P-Trap Repair & Replacement in Los Angeles
Power Pro Plumbing, Heating & Air repairs and replaces P-traps across Los Angeles and Orange County; the U-shaped pipe under your sink holds water that blocks sewer gas, so a failing trap causes drips, odors, and slow drains.
We work on every P-trap in the house — kitchen sinks, bathroom sinks, laundry lines, and the harder-to-reach traps serving tubs and showers. It's a small job we do right: correct materials, correct slope, hand-tight compression fittings that seal without cracking, and a full leak test before we pack up.
A persistent sewer smell isn't always the trap itself — sometimes a rarely used drain simply dries out, and sometimes the problem is deeper in the drain system. We'll diagnose honestly and fix the actual cause.
What are the signs your P-trap needs attention?
A P-trap needs attention when you notice any of these signs:
- Water dripping or pooling in the cabinet under a sink
- Sewer or rotten-egg odors from a drain
- Visible corrosion on older metal traps
- A trap that clogs repeatedly — debris settles in the bend by design
- Leaks that return after DIY tightening (often a cracked washer or misaligned joint)
Why does a cheap P-trap deserve a proper job?
A cheap P-trap still deserves a proper job because PVC, ABS, and chromed metal traps each seal differently. Overtightened compression nuts crack; misaligned tailpieces leak slowly enough to rot a cabinet floor before anyone notices; and a trap installed without proper slope holds debris and clogs. Our plumbers get the details right the first time — and while we're under the sink, we'll check the shut-off valves and supply lines too, since those fail at the same age traps do.
P-Trap Services FAQs
Why does my drain smell like sewage? +
The most common cause is a dry or leaking P-trap that's lost its water seal, letting sewer gas rise into the room. In rarely used bathrooms, simply running water restores the seal. If odors persist, the trap may be leaking or the problem may be venting or a deeper drain issue — worth a professional look.
Can I replace a P-trap myself? +
Handy homeowners sometimes do — but recurring leaks after DIY replacements are one of our most common calls. If your trap is metal, corroded, or misaligned with the wall stub-out, or if the leak returns after your fix, it's time to have it done professionally.
How long does a P-trap replacement take? +
Usually under an hour for an accessible sink trap, including a leak test. Traps serving tubs and showers can take longer depending on access.
My trap keeps clogging — is that normal? +
The trap's bend naturally catches debris, so occasional clogs happen. Frequent ones suggest heavy grease or buildup in the line beyond the trap, which a proper drain cleaning solves far better than repeatedly opening the trap.
