RV Water Pump and Plumbing Repair in Harlingen, TX

How you know the pump or plumbing is in trouble

The signs show up at the faucets first. A pump that runs without shutting off, one that cycles on and off every few seconds, and one that runs but gives no pressure each point to a different problem, and we sort out which. Grinding or clicking from the pump compartment is another warning. On the plumbing side, look for water under the coach, damp spots near fittings, or pressure that drops at one sink while the others still flow. A fitting that seeps even a little will eventually let go, so call before it does.

What is usually causing it

Pumps wear out, and once one can't build and hold pressure, replacement is the fix. Sometimes the pressure switch is the problem and the pump is fine. Other times the motor is good and the wiring or a connection has failed. PEX fittings are common in RV fresh-water systems, and they leak at the joint when a clamp wasn't tightened properly or the connection has worked loose. The ground here moves with seasonal moisture cycles, so a coach parked in one spot for months can shift slightly, and that strain tends to show up first at joints.

How we find the actual fault

We start on the electrical side: voltage at the pump, then the pressure switch, since a failed switch makes a good pump act dead. We inspect the stranded electrical wire for breaks and check the ground connections. Then we go over every fitting for leaks. We don't replace anything we haven't confirmed is bad, so you pay for a pump, a switch, a fitting, or a combination only when the testing shows it's needed.

What the repair involves

Before we service the pump, we switch it off and drain the water from the system. A replacement pump goes in with flexible inlet and outlet hose, and we secure each barb connection with a hose clamp. We reconnect the stranded wire and fit a new pump pressure switch if the old one has failed. For a leaking PEX connection, we open up access to the fitting, replace it, and check it under pressure before we leave.

What you will pay

PEX fitting repair runs $145 to $285 per location. Where you land in that range depends on how much has to come apart to reach the fitting. Pump replacement is quoted separately, since it depends on the pump and on whether the pressure switch or wiring also needs replacing. If we find something different once things are open, we call you and go over the options before doing any added work.

What to expect when you book

We come to your RV, whether you're parked at a campground or on your own property. After the repair, we run the system at the faucets and check the new connections for leaks. If your fresh-water system needs attention, call and we'll get you on the schedule.
