Water leaks in an RV are sneaky. In a house, a leak usually shows up pretty fast - wet drywall, dripping ceiling, puddle on the floor. In an RV, the water runs along the subfloor, soaks into the insulation, and drips out the belly wrap underneath the rig. By the time you see water on the ground, it might have been leaking for days or weeks.
The most common leak sources we find in Port St. Lucie are push-fit PEX fittings that have loosened over time (road vibration does this), compression fittings at the water pump inlet/outlet, cracked water heater bypass valves, and city water inlet connections that seep when pressurized. Florida's heat accelerates every one of these failures - plastic and rubber don't last as long when the underbelly hits 140+ degrees on a summer afternoon.
We use a systematic approach to find leaks: pressurize the system, check every fitting and connection point, and inspect the underbelly wrap for wet spots. Once we find the source, the fix is usually straightforward - cut out the bad section of PEX, replace the fitting, pressure test again, and verify it holds. If we need to open the belly wrap, we reseal it properly when we're done. Most emergency plumbing calls we get in this area are water leaks, and we can usually have them fixed the same day.
Most likely a fitting or line failure in the fresh water system. Turn on the pump, close all faucets, and watch for drips underneath. If the pump keeps cycling on and off with nothing open, there's definitely a leak. $90-180 to fix depending on the location.
Classic leak indicator. The pump builds pressure, the leak slowly drops it, and the pump kicks on again. This can drain your battery and your fresh tank. We pressurize and trace it - usually a fitting behind a wall or under the floor.
Water is running along the subfloor and collecting at the lowest point of the belly wrap. The leak could be anywhere upstream. We need to open the belly, trace it back to the source, and fix it. $150-250 including belly reseal.
City water runs at 40-60 PSI, the pump runs at about 40 PSI. Higher city pressure can expose a weak fitting that holds fine at pump pressure. A pressure regulator helps, but the real fix is replacing the weak connection.
Could be the T&P relief valve (pressure/temp safety valve), a cracked drain plug, a corroded tank, or a failed bypass valve. We check all four. If it's the anode rod hole or a rusted fitting, it's usually a quick fix. Need a full water heater repair? We handle that too.
This means water has been sitting in the subfloor for a while. The leak itself might be a $100 fix, but the floor damage could be more serious. We'll fix the leak and give you an honest assessment of the floor condition.
We stock the most common RV water line repair parts so we can fix your leak the same visit. Here's what's on our truck and what you should know about each one.
We carry both red (hot) and blue (cold) PEX in the two sizes used in almost every RV built since 2005. PEX is flexible, freeze-resistant, and holds up better than CPVC in a rig that vibrates down the highway. When a section fails, we cut it out and splice in new tubing with proper fittings. According to SharkBite's specifications, their push-fit connections are rated for 200 PSI at 73 degrees F, well above anything an RV system will see.
Push-fit fittings are fast and reliable when installed right. The problem is that road vibration can work them loose over time, especially at bends and tees. We carry both push-fit connectors and copper crimp rings. For lines that see a lot of movement, we'll often recommend crimped connections since they're more vibration-resistant than push-fit.
Shurflo 4008 and Flojet Triplex are the two most common RV water pumps on the market. We carry seal kits, diaphragm kits, and complete replacement pumps for both brands. Pump connection leaks are one of the top three calls we get for RV water line repair in the Port St. Lucie area. The inlet and outlet barb fittings are usually the weak point.
We stock standard and flush-mount city water inlets, adjustable pressure regulators (40-50 PSI range), and water heater bypass valve assemblies. The city water inlet is exposed to sun and rain 24/7 on most rigs, and the O-ring inside dries out faster than you'd think. A leaking inlet is a 30-minute fix if we've got the part, and we almost always do.
Call 772-276-6465 or request an estimate online. Tell us what you're seeing - water under the rig, pump cycling on its own, wet belly wrap, dripping from a compartment. The more detail, the better we can prep. We'll schedule you same or next day.
Our tech pressurizes the water system, checks every fitting, valve, and connection point, and inspects the underbelly wrap for wet spots. Most leaks take 20-30 minutes to trace. You get a written estimate before we start any repair work - no surprises.
We cut out the bad section of PEX, replace the fitting or valve, and pressure test the system again to make sure it holds. If we opened the belly wrap, we reseal it properly. Most RV water leak repairs are done in under two hours. You're back to normal the same day.

Pump was cycling on and off all night. Tech came out, pressurized the system, and found a fitting behind the shower wall that had loosened up from road vibration. Replaced it in 30 minutes and we haven't had the issue since.
Found a puddle under our fifth wheel after it sat in storage all summer. They traced it to a cracked bypass valve on the water heater. Quick fix, fair price, and they checked the rest of the system while they were at it.
Water was seeping out the belly wrap for weeks before we figured out what was happening. Tech opened it up, found a split PEX line right where it made a bend, replaced the whole section and resealed the belly. No issues since. Wish we'd called sooner.
Most leak repairs run $90-250. A simple fitting swap is on the low end. A leak that requires opening the underbelly, tracing the source, and resealing is on the higher end. We always give you a written estimate before starting any work.
We pressurize the system and systematically check every connection point, fitting, valve, and line. We also inspect the underbelly wrap for wet spots and use the pump short-cycle test to confirm there's an active leak. Most leaks take 20-30 minutes to trace.
Sometimes, if the leak is at an accessible fitting, valve, or connection point inside the RV. But if the leak is in a line that runs through the floor, we'll need to open the belly wrap to get to it. We always reseal the belly when we're done.
Rubber seals and plastic fittings dry out, shrink, and crack when they're not in use, especially in Florida heat. Pump seals, water heater bypass valves, and push-fit fittings are the usual culprits after long storage. This is one of the most common calls we get.
Yes, eventually. Water sitting in the subfloor leads to delamination, mold, and rot. A $100 leak repair today can prevent a $2,000+ floor repair next year. If you see any signs of a leak, don't wait on it.
Yes. Fresh water leaks from pressurized lines (pump or city water) and drain leaks from grey water sinks and shower are both in our wheelhouse. Different systems, different fittings, but we handle both on the same visit.
