Some minor repairs are reasonable DIY — replacing a supply line, tightening a slip joint under a sink, swapping a washer. Anything inside a wall, under a slab, on a gas line, or involving soldering or the main supply belongs to a licensed plumber.

Reasonable to Handle Yourself

  • Replacing a braided supply line to a toilet or faucet
  • Tightening or re-washering a slip joint under a sink
  • Replacing a P-trap on an accessible drain
  • Swapping a toilet flapper or fill valve
  • Cleaning an aerator

These are visible, low-pressure, and easy to reverse if it does not go well. Shut off the fixture stop first and keep a bucket handy.

Call a Professional For

  • Anything inside a wall, ceiling, or under a slab. Finding the leak is the hard part, and cutting into the wrong spot creates more damage than the leak did.
  • Gas lines. Not a judgment call — this is a life-safety issue and licensed work in New Mexico. See gas line service.
  • Soldering copper. Open flame in a wall cavity next to insulation and framing is how house fires start.
  • Main supply lines and shutoff valves.
  • Water heater connections, where venting and combustion are involved.
  • Galvanized pipe. Cutting into corroded galvanized routinely reveals more failing pipe adjacent to the repair.
  • Anything requiring a permit.

Why the Stakes Are Higher Than They Look

A supply line under pressure that fails while you are at work floods a house. Unpermitted plumbing surfaces later during a home sale or complicates an insurance claim on water damage. And a repair done without addressing the cause — usually high water pressure or corroded galvanized — just moves the failure a few feet down the line.

Check the Cause, Not Just the Symptom

High incoming pressure without a working pressure reducing valve stresses every joint in the house and produces repeat leaks. Hard water scale and aging galvanized are the other common Albuquerque culprits. A professional will look at the system rather than the single joint.

Two Things to Do Before Anything Else

Know where your main shutoff is and confirm it turns. And if you are unsure whether a repair is within your ability, it probably is not — a leak you can stop is far cheaper than one you make worse.
