Sewer Line Repair & Replacement in Rancho Cucamonga
Camera-verified diagnosis, trenchless options, and honest pricing from a local, owner-operated plumber. Call (909) 727-2959, day or night.
Your sewer line is the one pipe you never see and the one you can least afford to ignore. When it fails, wastewater from every toilet, sink, and shower has nowhere to go but back into your home. W.P. Plumbing repairs and replaces main sewer lines across Rancho Cucamonga and the Inland Empire, and we're available 24/7 when a backup can't wait.
Rancho Cucamonga is hard on sewer lines. Mature trees in older neighborhoods like Alta Loma and Etiwanda send roots straight into pipe joints looking for water. Homes built before 1980 often have clay or cast iron lines that crack, sag, and corrode. Add our hard water scaling up the inside of the pipe, and a line that drained fine for decades can fail in a single season.
Billy runs W.P. Plumbing the way you'd want it run: camera inspection first, footage you can see yourself, a firm price before work starts, and no cut corners once it does. Estimates on sewer main repair and replacement are free, and every job is backed by our workmanship guarantee. Licensed, bonded, and insured.
Signs Your Sewer Line Is Failing
- Every drain in the house runs slow at once
- Gurgling toilets when the washing machine drains
- Sewage smell in the yard or near floor drains
- Soggy, extra-green patches of lawn over the sewer path
- Backups in the tub or shower, the lowest drains first
- Repeated clogs that snaking only fixes for a few weeks

Why Homeowners Choose W.P. Plumbing
Camera Before Shovel
We run a sewer camera down the line before we quote anything. You see the footage yourself, so you know exactly what's broken and where before we dig.
Trenchless When It Fits
Pipe lining and pipe bursting let us replace a failed line through one or two access pits instead of trenching your whole yard. Most jobs finish in a day.
Upfront Pricing, Free Estimates
Main line work gets a free estimate and a firm price before we start. No surprise charges when the job is done. That's how Billy runs this company.
Licensed and On Call 24/7
W.P. Plumbing is licensed, bonded, and insured. Sewer backups don't wait for business hours, and neither do we. Often on-site within 60 minutes.

Frequently Asked Questions
How much does sewer line repair cost in Rancho Cucamonga?
It depends on what the camera finds. A single cracked section near the cleanout costs far less than a full line replacement under a driveway. That's why we start with an inspection and give you a firm, written price before any work begins. Estimates on main line repair and replacement are free, and the price we quote is the price you pay.
Can you replace my sewer line without digging up the yard?
Usually, yes. Trenchless pipe lining cures a new pipe inside the old one through a single access point. Pipe bursting pulls a new HDPE line through while breaking the old pipe apart. Both typically finish in one day with one or two small pits instead of an open trench. The camera inspection tells us whether your line qualifies.
How do I know if it's a clog or a broken sewer line?
A clog usually affects one fixture. A broken line affects the whole house: every drain runs slow, the lowest drain backs up first, and toilets gurgle when the washer drains. If a plumber has snaked the same line more than once in a year, the pipe itself is the problem. A camera inspection settles it in about an hour.
Will hydro jetting fix roots in my sewer line?
It clears them. Our jetter runs up to 4,000 PSI and cuts roots, grease, and scale out of the pipe, restoring full flow. But roots got in through a crack or a failed joint, and they grow back through the same opening. Jetting buys time; lining or replacing the damaged section fixes it for good. We'll show you both options on camera.
