RV Plumbing Repair — Mobile Service in Stockton & the Central Valley
A leaking fresh line, a valve that won't close, or a pump that runs forever — RV plumbing failures make a rig unlivable fast. I fix water pumps, supply lines, fixtures, and tank valves on-site, and I winterize rigs before the rare Central Valley freeze so you don't burst a line.

Water Pump Won’t Shut Off
If your pump runs without a faucet open, you likely have a hidden leak or a failing pressure switch. I diagnose the pressure drop and stop the cycle.
Leaking Toilet Floor Seal
Water pooling around the base of your Dometic or Thetford toilet is a floor-rotter waiting to happen. I replace ball seals and mounting gaskets to keep it dry.
Common Problems I See
Cracked PEX Fittings
RV plumbing uses plastic fittings that crack under vibration or temperature swings. I carry PEX crimp tools and high-grade fittings to fix leaks behind cabinets.
False Tank Level Reading
If your sensors say 'Full' when your tanks are empty, build-up or wiring faults are to blame. I clean and repair monitor systems so you know exactly what’s in the tank.
Seized Waste Gate Valves
If your black or gray tank handle won't pull—or worse, won't close—it puts your trip on hold. I replace cables and blade valves on-site.
Oxidized Delta Fittings
Rigs near the Delta marinas face unique humidity and oxidation issues. I repair brass and plastic connections that have degraded in high-moisture environments.
How the On-Site Visit Works
01
I Show Up
You call or text, we pick a time, and I drive to where the RV is parked: driveway, storage lot, campground, marina, or roadside.
02
I Diagnose and Quote
I run the real diagnosis on the spot and give you the price before any work begins. No surprise line items.
03
I Repair, Usually in One Visit
I carry the common parts. Most jobs finish the same day, where the rig sits.
Central Valley–Specific Notes
While the Central Valley is known for heat, our rare winter freezes can split un-winterized RV lines overnight. Whether your rig is parked at a Delta marina or in a Stockton storage lot, proper PEX crimping and professional blow-out service are essential. I use specialized tools to ensure every fitting is pressure-tight, protecting your plumbing system against the temperature swings unique to the Valley.
