Frequently Asked Questions

Yes. A gas leak from a water heater is dangerous and can lead to fire, explosion, or carbon monoxide exposure. If you smell gas or suspect a leak, leave the home immediately and contact emergency services or your gas provider before having a licensed professional inspect and repair the water heater.

Why Gas Leaks From Water Heaters Are a Serious Safety Issue

Gas water heaters rely on a controlled flow of natural gas to heat water safely. When that gas escapes due to a faulty connection, damaged gas valve, or internal component failure, it creates a serious safety risk. Even a small leak can allow gas to build up in enclosed spaces, increasing the risk of fire, explosion, or carbon monoxide exposure.

Some homeowners first notice a gas leak by smelling sulfur or “rotten egg” odors near the water heater, while others may hear hissing sounds or experience unexplained pilot light issues. These warning signs should never be ignored. Gas leaks are not something to troubleshoot or repair without proper training and equipment.

In Albuquerque homes, aging water heaters, seismic movement, corrosion, or improper past installations can all contribute to gas-related issues over time. That’s why any suspected gas leak should be treated as an emergency. After the immediate danger is addressed, the water heater should be professionally inspected to determine whether repair is possible or if replacement is the safer option.

What Counts as an Emergency?

Not every urgent situation requires a middle-of-the-night dispatch — but many do. When there’s a safety concern, flooding risk, sewer issue, or a major comfort system failure in extreme weather, it should be treated as an emergency.

Emergencies usually fall into one of three categories:

  1. Water that’s running where it shouldn’t be
  2. HVAC equipment that has failed in unsafe conditions
  3. Sewer issues that threaten your health or property

If you’re unsure, calling is always the right move — we’ll walk through the problem and help you decide.

Common Emergencies We Handle

Common emergencies usually fall into two categories — urgent plumbing/drain issues and heating or cooling failures during unsafe conditions. Below is a quick guide to the types of problems we treat as emergencies, along with resources from our blog to help you understand what’s happening.

Emergency Issue (with Blog Link) Why It’s an Emergency

Burst Pipe or Major Leak
Water escaping where it shouldn’t can lead to structural damage, mold growth, and electrical hazards within minutes. Shut off your water and call immediately.

Sewer Backup or Strong Sewer Odor
Sewage backing up into drains or entering your home is a direct health risk. This requires immediate professional attention.
No Water or Sudden Loss of Water Pressure A sudden drop in water pressure or no water at all may signal a broken main line, a major underground leak, or severe blockage. These issues can worsen rapidly and require prompt diagnosis.

No Heat During Freezing Temperatures
In freezing weather, losing heat can quickly become unsafe for children, older adults, and pets. This should always be treated as an emergency.

HVAC Failure During Extreme Heat
Albuquerque heat can push indoor temperatures to dangerous levels. A sudden AC failure or evaporative cooler blowing hot air during a heatwave is more than uncomfortable — it can be unsafe.

Burning Smells, Smoke, or Electrical Issues from HVAC Equipment
These symptoms may indicate overheating, electrical failure, or fire risk. Turn off the system and call immediately for guidance.

A P-trap is actually a U-shaped bend in the drainpipe beneath your sink or other plumbing fixture. When water flows through the drain, a small amount stays behind in that curved section. This leftover water forms an airtight seal so sewer gases can’t travel backward into your home.
It’s called a P-trap because, when connected to the drain arm in the wall, the full assembly resembles the shape of the letter “P.” Go ahead at take a look under the sink, we’ll wait.

P-traps are typically made from:

  • PVC (most common in homes today)
  • ABS (in some regions)
  • Chrome-plated metal (common in older or exposed installations)

Bonus tip: Older homes sometimes used S-traps, which loop downward in an “S” shape. These are no longer allowed by code because they siphon dry too easily, causing sewer smells. P-traps replaced them as the safer, modern standard.

How P-Traps Work

The P-trap uses a very simple physics principle: water blocks air.

Here’s what happens each time you run the faucet:

  1. Water flows through the drain.
  2. Some water stays in the bend of the pipe.
  3. That water blocks air from moving backward.
  4. Wastewater continues down the drain line toward the sewer.

A P-trap can stop working if:

  • the water evaporates (common in rarely used fixtures),
  • the trap gets clogged,
  • the trap leaks,
  • or improper venting causes the trap to siphon empty.

Where You’ll Find a P-Trap in a Home

P-traps aren’t just under bathroom sinks — they’re everywhere wastewater leaves a fixture.

1. Under Sinks

  • Kitchen sinks
  • Bathroom sinks
  • Laundry/utility sinks

These are the most visible and the easiest to service.

2. Showers, Tubs & Floor Drains

You won’t see these traps, but they’re there — hidden under the floor or inside the framing.

3. Appliances & Laundry Drains

Washing machines and some dishwashers connect through systems that rely on a plumbing trap to prevent sewer odors.

Do Showers Have P-Traps?

Yes. Building code requires every shower to have a functioning P-trap.

Why it matters:

  • Prevents sewer odors
  • Catches hair/soap debris before it reaches the main line
  • Maintains sanitary indoor air

If you smell sewage near a shower, the trap may be:

  • clogged,
  • dry,
  • cracked,
  • or not installed correctly.

Do Toilets Have P-Traps?

Yes, but not the kind you see under a sink.

A toilet has a built-in P-trap molded directly into the porcelain bowl. This is why water always sits in the bottom of the toilet — that’s the trap seal preventing odors.

Because toilets have their own internal traps, they do not use an additional trap in the floor line.

Common P-Trap Problems & How to Fix Them

Even though P-traps are simple and reliable, a few issues come up again and again in Albuquerque homes. The most common include dry traps, leaks, cracks, clogs, and installation mistakes. Knowing the signs early helps you avoid sewer odors, water damage, and costly repairs down the line.

1. Dry P-Traps (Very Common in Guest Bathrooms)

A P-trap needs water to seal out sewer gases. When a sink, shower, or floor drain isn’t used regularly, the water in the trap slowly evaporates. Once the water seal disappears, nothing stops those sewer gases from creeping into your home.

Signs of a Dry Trap

  • Strong sewer or “rotten egg” smell near the drain
  • Odor returns even after cleaning the sink
  • Gurgling sounds when water runs in nearby fixtures

How to Fix or Prevent It

  • Run water for 10–15 seconds at least once a week in unused bathrooms or basements.
  • If the odor returns immediately, the trap may have a leak or venting issue that needs attention.

2. Leaks and Cracks in the P-Trap

Leaks are the second most common P-trap issue. They typically occur from:

  • Corrosion (older chrome or metal traps rust over time)
  • Improper installation
  • Loose slip-joint nuts and worn washers
  • Physical shifting or impact inside the cabinet
  • Cracks in older or thin plastic traps

Because the trap sits under the sink, leaks often go unnoticed until they’ve caused damage.

Warning Signs

  • Water droplets or pooling under the sink
  • Musty smell in the cabinet
  • Swollen, warped, or discolored wood
  • Mold or mildew spots

Why It Matters

Even small, slow leaks can cause rot, cabinet damage, mold growth, or a broken trap seal — allowing sewer gases into your home.

What to Do

  • Tighten slip nuts gently — overtightening can crack the trap.
  • If corrosion, cracks, or brittle plastic is visible, replacement is the safest option.
  • PVC and ABS traps are good modern upgrades because they resist corrosion and damage.

3. Clogged P-Traps

Clogs form when debris builds up inside the bend of the trap. For sinks and showers, this often includes:

  • Hair
  • Grease
  • Soap scum
  • Food particles
  • Shaving products
  • Sediment buildup

Signs of a Clogged Trap

  • Slow draining
  • Standing water in the sink or shower
  • Gurgling after draining
  • Sewer odors even when the trap has water

Why You Should Avoid DIY Chemicals

  • Chemical drain cleaners can:
  • Corrode metal traps
  • Damage older plastic traps
  • Sit in the trap if the clog doesn’t clear, causing further deterioration
  • Release fumes that are hazardous indoors

Wire-hanger-style DIY methods can scratch the inside of the pipe, creating rough surfaces where future clogs form even faster.

Best Solution

Have a licensed plumber safely remove and clear the trap, check the rest of the drain line, and ensure no deeper blockage is forming.

4. When to Replace Your P-Trap Instead of Repairing It

A full replacement may be needed if:

  • The trap is heavily corroded
  • Cracks are visible
  • Fittings no longer tighten properly
  • Odors persist even after cleaning
  • The trap was improperly installed
  • You’ve repaired leaks more than once

New PVC or ABS traps are durable, affordable, and handle moisture better than old metal ones.

Regular Maintenance Helps Prevent Major Problems

Routine drain cleaning and periodic plumbing inspections help catch issues early. A plumber can confirm:

  • The trap has a solid seal
  • The drain arm has proper slope
  • Venting is correct
  • No double-trapping exists
  • No hidden leaks or slow drips are starting

This type of maintenance protects your home from both sewer odors and long-term water damage, especially in older Albuquerque neighborhoods with aging plumbing.

Mineral scale is one of the most common, and most overlooked, causes of tankless water heater problems in Albuquerque homes. Our local water contains natural minerals like calcium and magnesium, which gradually collect inside tankless systems, especially on the heat exchanger. Over time, that buildup acts like insulation, forcing the unit to work harder to deliver hot water efficiently.

As scale increases, homeowners may notice slower hot water delivery, inconsistent temperatures, higher energy use, or new system noises. A professional tankless water heater descaler treatment dissolves hardened mineral buildup, restores proper heat transfer, and helps the system operate the way it was designed to.

Why Descaling a Tankless Water Heater Is So Important

The heat exchanger is the heart of a tankless water heater — and one of its most expensive components. Scale buildup restricts heat transfer, increases operating temperatures, and adds unnecessary strain to internal parts.

Many manufacturers list descaling as required maintenance. Skipping it doesn’t just reduce efficiency; it can shorten the life of the unit and, in some cases, affect warranty coverage. Regular descaling is a preventative step that protects your investment and helps keep daily routines running smoothly.

Descaling vs. Flushing – What’s the Difference?

These two terms are often confused, but they serve different purposes.

Descaling uses an approved tankless water heater descaler to chemically break down hardened mineral deposits bonded to the heat exchanger and internal water pathways. This is the only way to remove stubborn scale buildup caused by hard water.

Flushing moves clean water or a mild rinse through the system to clear out loosened debris after descaling. Flushing alone does not remove hardened scale.

For best results, professional descaling is typically followed by a post-service flush to clear residual material. This process uses an approved tankless water heater cleaner to break down mineral scale, then flushes the system to remove loosened buildup. In some situations, especially with older equipment or systems that haven’t been maintained in years, a technician may recommend additional inspection before any cleaning is performed. When that happens, we explain what we’re seeing and recommend the safest path forward.

How Often Should You Descale a Tankless Water Heater?

For most Albuquerque homes, annual descaling is a solid baseline.

Homes with very hard water, high hot water usage, or skipped past maintenance may benefit from descaling every 6 to 9 months. Water quality can vary by neighborhood — and even by street — which is why the best timing is based on actual system condition rather than a one-size-fits-all rule.

Staying ahead of scale buildup helps maintain efficiency, prevent performance issues, and avoid more costly repairs down the road.

Signs Your Tankless System Needs Attention

Scale buildup often shows up gradually. Common warning signs include:

  • Hot water taking longer to reach faucets
  • Inconsistent temperatures during showers
  • Reduced flow when hot water is running
  • Error codes related to overheating or scale
  • New hissing, rumbling, or vibration sounds

These symptoms don’t always mean the system is failing — but they often point to mineral buildup affecting performance. A professional water heater descaler treatment can restore normal operation and reduce unnecessary wear on the heat exchanger.

Professional Tankless Heater Descaler vs. DIY Cleaning

DIY descaling is often presented as simple, but it comes with risks. Using the wrong solution, skipping steps, or missing early signs of damage can lead to leaks, component failure, or voided warranties.

Professional service is especially important for:

  • Older tankless systems
  • Units displaying error codes
  • Homes with very hard water
  • Systems that haven’t been serviced in several years

Our certified technicians evaluate the condition of the unit, select the appropriate tankless heater descaler, perform the cleaning safely, and verify proper operation afterward. It’s preventative care that protects your system and helps avoid larger repairs.

What Happens If You Skip Descaling?

Unchecked scale forces the heater to run longer and hotter to meet demand. That leads to higher energy use, increased stress on internal components, and a greater risk of overheating or shutdown.

Over time, performance declines and system lifespan can shorten. Regular descaling supports efficient operation and helps keep manufacturer requirements intact.

How Tankless Water Heaters Work Compared to Traditional Tank Systems

Tankless water heaters heat water on demand rather than storing hot water in a tank. When a hot water fixture is turned on, cold water flows through the unit and is heated instantly using gas burners or electric heating elements.

This design eliminates standby heat loss and allows for a longer system lifespan, but it also means tankless systems place greater demands on gas supply, electrical capacity, and venting. In Albuquerque homes, those requirements are often the main reason installation costs vary so widely.

What Affects Tankless Water Heater Installation Costs in Albuquerque

Several factors influence the cost of a tankless water heater and installation, especially in older or custom-built homes common throughout Albuquerque and Santa Fe. Key factors include:

  • Fuel type (gas or electric): Gas systems are more common for whole-home use but often require gas line and venting upgrades. Electric systems may need electrical panel upgrades to handle higher amperage.
  • Household hot water demand: Homes with multiple bathrooms or simultaneous hot water use need higher-capacity systems.
  • Existing utilities: Older homes may have undersized gas lines or limited electrical service.
  • Venting requirements: Gas tankless units usually require dedicated venting that differs from tank-style heaters.
  • Home age and layout: Accessibility, wall placement, and distance to exterior walls can impact labor and materials.

These details are usually evaluated during a professional water heater assessment.

Average Cost of Tankless Water Heater Units

The price of the tankless unit itself is only part of the total cost. Typical unit price ranges include:

  • Electric tankless water heaters: About $500–$1,500
    Often used for smaller homes, casitas, or point-of-use applications
  • Gas tankless water heaters: About $1,500–$3,500
    Common for whole-home systems in Albuquerque due to higher output capacity

Larger households generally need higher-capacity units, which increases equipment cost but helps avoid inconsistent hot water.

Installation Costs and Common Upgrade Expenses

Installation labor and required upgrades are where pricing can increase most noticeably. Common installation-related costs include:

  • Professional installation labor: Typically $1,500–$3,000, depending on complexity
  • Gas line upgrades: Often $500–$2,000 if the existing line is undersized
  • Electrical upgrades (electric systems): Panel or wiring upgrades may add $1,000–$2,500
  • Venting installation or modification: Commonly $500–$1,500 for gas systems
  • Condensate drainage and mounting: Costs vary based on location and home layout

Homes built before the 1990s are more likely to need one or more of these upgrades.

When Tankless Installation Costs Are Lower — or Higher

Lower-cost installation scenarios

  • Replacing an existing tankless water heater
  • Homes with modern gas lines or electrical panels
  • Straightforward venting and accessible mounting locations
  • Smaller households with moderate hot water usage

Higher-cost installation scenarios

  • Converting from a traditional tank water heater
  • Older Albuquerque homes with original utilities
  • Long venting runs or roof penetrations
  • Larger households with multiple bathrooms or high demand

A professional evaluation helps identify which category your home falls into.

Why Professional Installation Matters for Tankless Water Heaters

Tankless water heaters are efficient systems, but they are less forgiving than traditional tanks when installed incorrectly. Professional installation of your tankless heater helps ensure:

  • Safe gas and electrical connections
  • Proper venting and combustion air supply
  • Correct system sizing for Albuquerque’s elevation
  • Compliance with local plumbing and mechanical codes
  • Manufacturer warranty protection

Improper installation can lead to poor performance, safety concerns, or premature system failure.

Long-Term Cost and Lifespan Considerations

While tankless water heaters typically cost more to install upfront, many Albuquerque homeowners consider them a long-term investment.

Important long-term factors include:

  • Lifespan: Tankless systems often last 15–20 years, compared to 8–12 years for tank heaters.
  • Energy efficiency: Heating water on demand can reduce overall energy use.
  • Maintenance needs: Annual flushing is recommended to manage mineral buildup.
  • Repair considerations: Repairs may be more specialized but are less frequent over the system’s lifespan.

Over time, these benefits can help offset the higher initial installation cost.

When Tankless Installation Signals a Bigger Plumbing or Utility Issue

In some cases, planning a tankless installation uncovers larger concerns, such as:

  • Undersized gas supply lines
  • Aging or overloaded electrical panels
  • Inadequate venting pathways
  • Water pressure or flow limitations

Addressing these issues helps ensure the tankless system operates safely and reliably long term.

Making Sense of Tankless Water Heater Installation Costs

Tankless water heater installation costs can vary widely in Albuquerque because each home’s utilities, layout, and hot water needs are different. While some installations are fairly straightforward, others require upgrades to gas lines, electrical service, or venting to ensure the system operates safely and reliably.

Understanding what drives the cost helps homeowners avoid surprises and make informed decisions about whether a tankless system is the right fit. In many cases, the higher upfront investment is balanced by a longer system lifespan, improved efficiency, and consistent hot water performance over time.

A proper evaluation of your home’s existing setup is the most reliable way to determine what installation will involve and where your home falls within the typical cost range. This approach helps ensure the system is sized correctly, installed safely, and built to perform well for years to come.
