Backwater Valve Installation in Burbank & LA
Cheap insurance against the worst backup.
A backwater valve sits on your sewer line and does one job: it lets sewage flow out, and slams shut when the city main surges back toward your house. For homes below street level or in backup-prone areas, it’s the cheapest protection against the messiest disaster there is.

What installation covers:

- Testing — we verify the flapper moves freely and seals shut
Plumbing repair services

Faucet repair & replacement
That drip is money down the drain. Cartridges, seats, valves — or a whole new fixture if the old one isn’t worth saving.
Toilet repair & replacement
Running toilets, weak flushes, rocking bowls. Fill valves, flappers, wax rings — or a full replacement when it’s done.
Garbage disposal repair & replacement
Jammed, humming, or dead. We’ll try the reset and the honest fix first — and swap in a new unit, wired and tested, when it’s shot.

Leaky traps, loose faucets, cracked supply lines. The small stuff, fixed properly so it stays fixed.

How a backwater valve saves you
One moving part between you and the city main.
City mains push back
Heavy rain or a downstream blockage can send sewage back up your lateral. Gravity doesn’t care whose house is in the way.
Out yes, in never
Normal flow pushes the flapper open on its own. Reverse flow slams it shut. Simple, mechanical — no power needed.
Different from a backflow preventer
Backflow preventers protect drinking water (see our backflow testing page). Backwater valves protect your home from sewer surges. Different pipe, different job.

Backwater valve FAQ
What homeowners ask before installing one.
What’s the difference between a backwater valve and a backflow preventer?
A backwater valve is on your sewer line — it stops sewage from backing into your home. A backflow preventer is on your drinking water — it stops contamination. We do both; they’re separate devices on separate pipes.
Does my home need one?
If you’re below street level, have a history of backups, or your area’s sewer surcharges in heavy rain — probably. We evaluate for free.
Do backwater valves need maintenance?
Yes — the flapper has to move freely to seal. We recommend periodic cleaning, and we do it.
Will it affect normal drainage?
No. Normal flow pushes the flapper open on its own. You’ll never notice it’s there — until the day it saves you.
Do you charge by the hour?
No. Flat per-job pricing with a free estimate, agreed before work starts.
One valve. Zero sewage in the house.
