Mobile RV plumbing and water system repair
A drip under the sink and a pump that keeps cycling tell you different things. Let Kirk know what you’re seeing and whether it happens on city water, the onboard tank or both.
Water pumps, fixtures and leaks
Water pumps and fresh water lines
Ask about low flow, pumps that run without building pressure, leaking fittings and water lines damaged after storage or freezing.
Toilets, faucets and drains
Common symptoms include a toilet that won’t hold water, a leaking faucet base, a wet cabinet under the sink or water dripping from a drain connection.
Tank fittings and water heater concerns
Note whether water appears while filling, using a fixture or draining a tank. If hot water is the issue, include the heater’s model and whether the problem is with temperature, flow or a visible leak.
Common questions
Why does the pump come on when all the taps are closed?
A pump that briefly comes on again is responding to a drop in pressure. That can come from a small drip, a toilet valve that doesn’t seal or another place where pressure is being lost. Tell Kirk how often it cycles, whether you see water anywhere and whether the issue started after a repair or the first use of the season.
Why does the RV leak on city water but stay dry on the pump?
The city-water inlet and its connections are involved when a hose is attached. Pressure from the supply can also expose a weak fitting that behaves differently on the onboard pump. Tell Kirk whether the leak starts immediately when the hose is connected or only when you open a fixture. The timing narrows down the section to check.
How can I tell if the leak is from a drain or a supply line?
Water that appears only after you use a sink or shower points toward the drain or fixture. A leak that continues while the system is pressurized with everything turned off suggests a supply-side issue. Describe where the water first appears and what was in use, since water can run behind a cabinet before it reaches the floor.
What if there’s good cold-water flow but hardly any hot water?
If it happens at several taps, the issue may be shared by the hot-water side, such as the water-heater bypass or a restriction near the heater. A problem at one tap points more toward that fixture. Include the heater model and mention any recent winterization or spring startup so Kirk knows what was changed.
