Replace a shower drain when you see water damage or staining on the ceiling below, persistent odor that cleaning does not resolve, visible corrosion or cracking on the drain body, repeat clogs at the same point, or a drain that has separated from the pan or tile.

The Signs

  • Leaking below. Water stains on a ceiling under an upstairs shower, or dampness in a crawlspace, usually means the drain body or its connection to the pan has failed. This is the most urgent sign — the water is going somewhere, and it is doing damage on the way.
  • Persistent odor that returns after cleaning, which suggests a cracked trap or a failed seal rather than buildup.
  • Visible corrosion or cracking. Older brass and cast iron drain bodies corrode; plastic can crack from settling or impact.
  • Repeat clogs at the same spot — a damaged or corroded drain catches debris that a smooth one passes.
  • The drain has loosened from the shower pan or tile, breaking the waterproof seal.
  • Standing water that never fully clears even after cleaning.

Cleaning vs. Replacement

Most slow shower drains are buildup, not failure. Hair bound with soap scum and mineral scale narrows the opening over months. If a professional drain cleaning restores full flow and the problem stays away for a year, the drain is fine. If flow never fully returns, or clogs recur within weeks, something is wrong with the drain itself.

Why Albuquerque Drains Corrode

Hard water accelerates mineral scaling inside the drain body, and older homes here frequently have brass or cast iron assemblies that have been in service for decades. Scale narrows the passage permanently — no amount of cleaning restores what corrosion has taken.

What Replacement Involves

It depends on access. A drain accessible from a crawlspace below is straightforward. One in a slab-on-grade home — most of Albuquerque — may require cutting concrete or working through the shower pan, which usually means tile or pan work as well. We evaluate access before quoting, so the number you get is real.
