Fast, Local Help: Mobile RV Plumbing Repair Across Port St. Lucie
We offer mobile rv repair with same-day slots most weekdays. We service PSL neighborhoods like Tradition, Saint Lucie West, Torino, Sandpiper Bay, and near Crosstown Parkway. We’re usually 25 to 40 minutes from Fort Pierce, Jensen Beach, and Palm City, depending on traffic on US-1 and I-95. Got a leak at Savannas Preserve or by the Mets stadium at Clover Park? We’ve been there. We bring SharkBite fittings, PEX-B, crimps, faucets, check valves, and a new pump if yours quit.
Cost to expect: basic leak find and fix starts at $189. Pump swaps are usually $295 to $475 with a Shurflo or Flojet. Water heater valve repairs run $225 to $375. If we need to pull panels or remove a toilet, add $65 to $140. Straight talk. No mystery fees.
The Most Common RV Plumbing Problems We Fix
Short answer: PEX leaks at fittings, cracked elbows from freeze damage, failed city water inlets, worn toilet seals, water pump cycling, and water heater valve failures. We also see gray and black tank valve jams, and fittings behind the shower that pop loose on bumpy roads. Sound familiar?
We carry PEX-B rolls, 1/2 inch and 3/8 inch, both copper ring and stainless cinch tools, plus angle stops, tee fittings, and 12V pump relays. We test with a pressure gauge at the city water inlet and run every faucet to catch hidden leaks. If your pump short cycles every 20 seconds, that’s usually a check valve leak or a tiny drip under a cabinet. We’ll prove it with a manometer and paper towel test. Simple, but it works.
We always test the city water inlet, regulator, and pressure under load.

What To Do Right Now If You See Water In Your RV
Direct answer: shut the pump off, close the city water valve, and kill the water heater power so it doesn’t dry fire. Then soak up the standing water and call us at . The longer it runs, the more base cabinets swell. And that’s a pain to fix.
We also recommend you:
Open the low point drains for 30 to 60 seconds if water keeps pooling. Check under the kitchen sink and behind the toilet. Those are the top two leak spots we find. If you're at a campground in St. Lucie County, ask the office about their water pressure. We see 80 to 110 PSI spikes in peak hours. No RV likes that. A fixed 45 PSI regulator is cheap insurance.
A Real Job We Did Last Week In Tradition
A customer in Tradition called at 7:40 am. “Floor’s buckling by the slide. Can you come now?” We were 25 minutes out. Found a cracked elbow feeding the galley faucet, hidden behind a false panel. Classic. Likely from a freeze event up north before they drove down. We cut out the bad elbow, re-routed with a 1/2 inch PEX-B loop to reduce stress, new cinch rings, added a shutoff valve, then pressure tested to 55 PSI. Dry as a bone. Total time 1 hour 15 minutes, bill was $259. They said, “Should’ve called sooner.” We hear that a lot.
Why RV Plumbing Leaks Happen After You Park In PSL Heat
Heat, vibration, and pressure spikes. That’s the trifecta. The Treasure Coast sun cooks lines in storage lots off Gatlin and Becker. Then you hit a pothole on St. Lucie West Boulevard, and a weak crimp lets go. Add campground pressure over 60 PSI, and we’ve got a mess. According to the Recreational Vehicle Industry Association, most RV plumbing uses PEX designed for residential work, but the install quality varies by model and year. We see better results from Winnebago and Grand Design, less from certain entry-level models. Honest take.
Tip we give every customer: use a brass pressure regulator with a gauge, not just the tiny barrel kind. We like Valterra with a dial. Set it to 45 to 55 PSI. Your pump and water heater will thank you.
A gauge-style regulator prevents pressure spikes from damaging your RV plumbing.

How We Diagnose RV Water Leaks Without Guessing
We start with a system pressure test at the city water inlet. Then we isolate fixtures. We’ll shut the water heater bypass, cap suspect branches if needed, and use a thermal camera on warm water lines. Sometimes we add UV dye to the fresh tank, run the pump, and check for dye at joints. We also listen. A cheap mechanic’s stethoscope picks up hissing behind panels. Old-school trick. Works great.
Average diagnosis time is 30 to 45 minutes on a simple leak. Multi-leak freeze damage can take 60 to 90 minutes. We only open what we must, and we put every panel back with fresh screws. If we break a trim clip, we replace it. No excuses.
Water Heaters, Pumps, And Toilets: Repairs We Do Daily
Short answer: yes, we handle all three. We stock Atwood/Dometic and Suburban elements, thermostats, and T&P valves. For pumps, Shurflo 4008 is our go-to. Quiet, reliable, parts are easy to get. We’re not fans of off-brand imports. Save yourself the second visit. For toilets, Thetford Aqua-Magic and Dometic 310s are common. Seal kits fix most leaks. If the bowl’s crazed or the pedal sticks, swap it.
According to Dometic’s current service manuals, electric elements on combo heaters should be replaced at the first sign of ground fault. We agree. A GFCI trip every shower isn’t normal. Fix it.


For manufacturer specs and service bulletins, we reference Dometic Service Manuals and Suburban’s water heater documentation from Airxcel. If we install new equipment, you get the exact model and serial in your receipt for warranty.
Seasonal Reality In St. Lucie County: Rainy Season Leaks
Every June through September, we get calls after afternoon storms. You think it’s plumbing, but it’s roof runoff sneaking behind a slide and into the floor. We’ll check your roof and slide seals while we’re there. If you need rv roof leak repair or slide out repair, our team handles that too. Preventive resealing once a year saves you thousands. Hurricane season? We recommend shutting off city water and using the pump so a blown hose doesn’t flood your rig while you’re gone.
If you need more than plumbing, see our pages on rv roof repair and rv slide out repair to understand pricing and timelines.
DIY Or Call A Pro? Our Honest Opinion
Small drips at a P-trap or a loose faucet line? Go for it. Tighten gently, use Teflon paste not tape on plastic threads, and don’t over-crimp a PEX ring with pliers. But a hidden leak behind a wall or a black tank valve job? Call us. We’ve seen too many DIYs turn into swollen floors and delaminated walls. A $259 fix can become a $2,900 floor rebuild. Not worth it.
And please, no silicone on pressurized fittings. We see people try this all the time and it never holds. Waste of time. Use the right parts once.
Emergency And Same-Day RV Plumbing Repair
We keep two trucks ready for emergency rv repair calls across Port St. Lucie, Jensen Beach, Stuart, Palm City, Fort Pierce, and Vero. Typical response time inside PSL is 60 to 120 minutes if you catch us before noon. After hours, we triage leaks, shut water down, and return at first light for permanent repair unless you want the after-hours rate. We’ll spell it out before we start. Call and say “urgent leak” so we prioritize you.
Looking for other services while we’re on site? We can handle rv ac repair, rv refrigerator repair, and basic rv electrical repair the same visit. Ask for a bundle price.
Same-day mobile service at a PSL campground after an overnight leak.
Codes, Specs, And Doing It Right The First Time
We follow manufacturer specs for PEX fittings and crimp standards, and we test to 60 PSI max, which matches what most RV makers consider safe. Florida doesn’t apply residential plumbing code to self-contained RVs the same way as homes, but safety rules still matter. According to the Florida Building Code (FBC 7th Edition), potable water systems should be protected from overpressure. That’s one reason we insist on pressure regulators at Treasure Coast campgrounds.
We also follow RVIA recommendations on propane and water heater service procedures. No shortcuts. No guessing. If a part is backordered, we’ll source an approved equivalent or tell you the lead time. Transparency beats surprises every time.
Warranty, Reviews, And What You Can Expect From Us
We warranty workmanship for 12 months on plumbing repairs. Parts carry the manufacturer warranty. We’re licensed and insured, and we’ve completed 3,500+ mobile rv repairs across the Treasure Coast since 2010. Current rating: 4.9 stars on 600+ reviews. If something isn’t right, we make it right.
