RV Water Leak Repair

Water leaks in an RV cause damage fast. Here's what we see.

RV water line leak being traced and repaired in Stuart FL

A water leak in a house is annoying. A water leak in an RV can cause thousands of dollars in structural damage within days. The floors, walls, and substructure of an RV are made of wood composite and foam, and once water gets into those materials it's a race against rot and mold. We see this all the time in Stuart, FL, especially on rigs that sit in storage for a few months.

The tricky part about RV water leaks is that water travels. A split PEX line behind the bathroom wall might show up as a wet spot in the bedroom carpet eight feet away. The water follows floor joists, wiring channels, and gravity, so the drip you see is almost never directly below the leak. That's why we start every job by pressurizing the freshwater system and systematically checking every connection point.

In Martin County, freeze damage is still a factor even though most people don't think of Florida as a freeze state. One cold snap with unprotected lines is enough to crack a PEX fitting or split a line. Beyond freeze damage, we deal with crimp ring failures from road vibration, corroded brass fittings, deteriorated pump seals, and factory defects on newer rigs where fittings weren't crimped properly at the plant.

Common Problems

6 RV water leak scenarios we deal with in Stuart.

01

"Water dripping under the RV when the pump is on"

Usually a split PEX line or failed fitting in the underbelly. When you turn on the pump and water drips from underneath within a minute, the leak is somewhere between the pump and a fixture. We pressurize the system and trace it to the exact fitting or line section. $110-325 depending on access.

02

"Wet spot on the floor but I can't find the source"

Water in an RV travels along joists and wiring channels before pooling. The wet spot is rarely directly below the leak. We check behind access panels, under sinks, around the water heater, and inside wall cavities to trace the path back to the origin. This is detective work, and it's what we're good at.

03

"Water pump cycles on and off by itself"

If the pump kicks on every few minutes when nothing's running, you've got a leak somewhere in the pressurized system. Even a tiny drip through a fitting can bleed off pressure and trigger the pump's pressure switch. We pressurize the system with the pump off and listen/look for the leak point.

04

"Leak only happens when connected to city water"

City water runs at 40-60 PSI, which is higher than what your onboard pump produces. A fitting or line that holds fine at pump pressure can blow at city pressure. This is why we always test at both pressures. If you don't have a pressure regulator, you should get one.

05

"Water heater compartment is wet on the outside"

Could be the drain plug, pressure relief valve, or a corroded tank. We check all three. A loose drain plug is a $65-110 fix. A blown PRV usually means the water heater is overheating, so we'll check the thermostat and high-limit switch while we're at it.

06

"Fresh water tank draining overnight"

If you fill the tank and it's low by morning without using any water, there's a constant leak somewhere. Usually it's a fitting at the tank outlet, a cracked tank fitting, or a failed check valve letting water back-siphon. We'll pressurize and check every connection from the tank forward.

Common Leak Points by RV Type

Where leaks happen depends on how the RV was built.

Different manufacturers route plumbing differently. Here's where we find the most leaks by RV type across Stuart and Martin County.

Travel Trailers (Jayco, Keystone, Forest River)

Most common leak points are in the underbelly where PEX lines connect to manifolds. Road vibration loosens crimp fittings over time. Jayco trailers tend to have better underbelly protection, but Keystone and Forest River models from 2018-2022 have a known issue with crimps near the water heater.

Fifth Wheels (Grand Design, Coachmen, Heartland)

Fifth wheels flex at the pin box connection, and plumbing lines near that junction take the most stress. We frequently find leaks in the forward basement area where lines run up to the bedroom and front bathroom. Grand Design rigs use a PEX manifold system that's generally reliable, but the manifold itself can develop leaks at the barb connections.

Class A / Class C Motorhomes

Engine vibration adds stress to every plumbing connection. We see more fitting failures on motorhomes than towables because of constant vibration during transit. The area behind the dash and above the cab-over (Class C) is a common trouble spot where lines run through tight spaces and rub against framing.

Class B Campervans (Winnebago, Thor, Pleasure-Way)

Tight quarters mean plumbing is crammed into small spaces with lots of bends and connections. The area behind the wet bath wall is the most common leak location. Access is limited, but we've worked on enough of these to know where to look and how to get in without tearing up the interior.

How It Works

Three steps to finding and fixing your RV water leak.

1

Call and Describe What You're Seeing

Call 772-280-3915 or submit an online request. Tell us where the water is showing up, when it happens (pump on, city water, all the time), and anything else you've noticed. The more detail, the faster we narrow it down.

2

We Track Down the Source On-Site

Our tech pressurizes the freshwater system and methodically checks every fitting, line, valve, and connection. We inspect the underbelly, inside cabinets, behind access panels, and around the pump and water heater. Written quote once we find the source.

3

Leak Repaired Same Visit

We carry PEX tubing, crimp fittings, SharkBite connectors, hose clamps, pump seal kits, and replacement valves on the truck. Most leak repairs are done in under 90 minutes once we've found the source. Underbelly jobs take a bit longer but still get done the same day.

Real Reviews

What Stuart customers say about our leak repairs.

Leave a Review
Our water pump kept cycling on and off every few minutes. Turns out a tiny fitting under the shower was weeping just enough to bleed the pressure. Tech found it, replaced the fitting, and the pump has been quiet ever since. Quick fix, fair price.

Underbelly leak on our Grand Design. Another company wanted us to tow it to their shop. Stuart RV Repair came to us, dropped the belly wrap section, found the bad crimp fitting, replaced it with proper PEX connections, and sealed everything back up. All done in the driveway in about two hours.

FAQ

RV water leak repair questions from Stuart customers.

How much does RV water leak repair cost in Stuart?

Leak repairs in Stuart typically run $85-325. A single fitting fix costs $85-140. PEX line replacement is $110-195. Underbelly access and repair runs $150-325 depending on the location and scope. A standalone leak detection pressure test costs $75-120. Written quote before any work starts.

How do you locate the source of an RV water leak?

We pressurize the freshwater system and check every fitting, connection, valve, and line. Water inside an RV travels along floor joists and wiring before showing up somewhere visible, so we trace it back to the origin. Systematic pressure testing is the only reliable way to find hidden leaks.

Can you fix underbelly leaks on-site?

Yes. We do underbelly leak repairs at your location regularly. We open the coroplast belly wrap in the affected area, access the leaking line or fitting, make the repair, and reseal the belly. Most underbelly jobs take 1-2 hours depending on depth and insulation access.

Why does my RV water pump keep cycling on and off?

If the pump kicks on every few minutes when no fixtures are running, there's a leak bleeding off system pressure. Even a tiny drip from a fitting or valve will cause the pump to cycle. We pressurize the system with the pump off and look for the leak point. It could be anywhere from the pump to the farthest faucet.

What causes PEX lines to fail in an RV?

Freeze damage is the top cause, even in South Florida. One cold snap with unprotected lines is enough. Road vibration loosens crimp fittings over time. UV exposure on lines near windows or exterior compartments degrades the PEX material. And some factory crimps, especially on 2018-2022 models, weren't done properly and fail prematurely.

How long does it take to find and fix an RV water leak?

Depends on the location. A visible fitting leak takes 30-60 minutes total. A buried underbelly leak takes 1-2 hours due to access time. The detection phase adds 20-40 minutes on tricky leaks where the water has traveled far from the source. Most jobs are completed in a single visit.
