Plumbing & Water Systems in Orange County, CA
RV plumbing systems are simple until they aren't. We repair fresh, gray, and black water systems, fix leaks at fittings and tanks, replace water pumps, service Atwood and Suburban water heaters, fix winter-cracked pipes, and unclog stubborn tank valves — all mobile, at your location.
Fully mobile — we come to your driveway, storage lot, or campsite. No towing needed.
Common Signs You Need Plumbing & Water Systems
If any of these sound familiar, give us a call — we can usually tell you over the phone how serious it is.
- Water pressure drops suddenly when you turn on a second faucet
- The water pump cycles on and off even when nothing is running
- There's a wet spot or drip in a basement bay or under the kitchen sink
- Hot water runs out within a couple of minutes
- Tank monitor lights show 'full' when the tank is actually empty
- The toilet won't hold water in the bowl between flushes
- You smell sewer gas inside the RV
Common Problems We Fix
Real failure modes we see on Orange County RVs — and how we repair each one.
Worn water pump diaphragm and check valves
Causes the pump to short-cycle and lose pressure. We replace the diaphragm or the whole pump and reprime the system.
Cracked fresh water tank or fitting
Plastic tanks crack with age and rough roads. We patch small cracks and replace tanks that are too far gone.
Leaking gray and black tank valves (T-handles)
Stuck or leaking gate valves are messy. We replace valves and seals so dumping is clean again.
Water heater element, thermostat, or anode rod failure
Suburban and Atwood units: element burnout, bad ECO/thermostat, gas valve issues, and seized anode rods are all common.
Frozen and cracked PEX or copper lines
Even SoCal sees freezes inland. Cracked lines under cabinets and in bays get cut out and replaced with PEX.
Toilet flapper, vacuum breaker, and flange seal failures
The classic 'won't hold water' or 'won't flush' problems. Most toilets we repair in under an hour.
What Happens If You Ignore It
Small RV problems compound fast. Here's what we see when these issues get put off too long.
- A slow leak under the sink rots the cabinet base and floor — wood damage spreads fast in an enclosed space.
- Sewer smell often means a dry P-trap or a failed tank vent — ignored, it can also indicate a cracked tank leaking into the underbelly.
- A water pump that short-cycles will burn out its motor and can cause fittings to fail from pressure spikes.
- Cracked plumbing lines will dump your full fresh tank into the underbelly the first time you fill it — soaking insulation and floor decking.

How Much Does Plumbing & Water Systems Cost?

- Whether the leak is accessible or behind a wall/floor
