RV water systems are different from a house. The pressures are lower, the fittings are push-fit or compression, and the whole system runs off a 12V pump that can fail for a dozen different reasons. We see these problems every week in Port St. Lucie, FL. Here's what we fix and what it typically costs.
Your 12V water pump is the heart of the whole system. We diagnose short-cycling, no-flow, and intermittent pressure issues. If the Shurflo or Flojet is done, we carry replacements on the truck and swap it out the same visit.
$120-220 parts + labor - 45-60 minWe work on Suburban and Atwood (Dometic) water heaters - both gas and electric models. Pilot won't stay lit, unit won't heat on electric mode, thermostat failures, anode rod replacements - we've done hundreds of these across the Treasure Coast.
$150-350 depending on fault RV water heater repair detailsPEX lines, push-fit fittings, and compression connections all fail eventually - especially after temperature swings or a hard freeze up north before the RV came south. We trace leaks, cut and replace damaged sections, and re-seal fittings properly. No patches that fail again in 60 days.
$90-200 depending on location and scope RV water leak repair detailsCracked tank fittings and inlet connections are common on older rigs. We can seal and replace plastic tank fittings, repair or replace the drain valve, and re-secure loose tank straps. If the tank itself has cracked, we'll give you an honest assessment on whether repair or replacement makes more sense.
$80-180 depending on damageFoot-pedal seals that leak, flush valves that won't seal, and full toilet replacements are all in a day's work. Dometic and Thetford are the two brands we see most. We carry common seal kits and can order a replacement unit if your toilet's beyond saving. Most toilet repairs take about an hour.
$100-280 depending on repair or replacement RV toilet repair detailsA bad city water inlet lets in water when it shouldn't or doesn't seal when you disconnect. Regulators can stick high and hammer your lines or drop low enough that you barely get pressure at the shower. Quick swap, usually under an hour, and the parts are cheap - this one often gets overlooked for months.
$80-150 parts and laborSlide valves seize up, crack, or just stop sealing properly - and once that happens the smell is unmistakable. We replace gate valves on both black and grey tanks, check the vent lines for blockages, and test the tank sensors while we're in there. Pair this with a tank sensor check if your gauges haven't read right in a while.
$100-200 depending on fitting configurationSlow drains, cracked shower pans, and leaking drain fittings can soak the floor structure before you even notice. We seal pan edges, clear and rebuild drain assemblies, and check the underbelly for signs of moisture migration. Catching this early saves a much more expensive floor repair later.
$120-250 depending on damage RV shower repair detailsThis almost always means the fresh tank is empty, a line is disconnected, or the pump has lost its prime. Don't ignore it - running a pump dry for long kills it fast.
Inconsistent pressure usually points to a failing pump diaphragm, a partially closed valve, or a restriction in the lines. On city water hookup it can also mean a regulator that's sticking.
Water pooling under the coach or wet patches on the underbelly wrap after you've been using the system is a leak. Could be a fitting, a drain connection, or the water heater relief valve. Find it before it damages the subfloor.
A gas unit that won't light is often a thermocouple or igniter issue - both inexpensive fixes. A unit that heats slowly on electric mode usually points to a failing element or thermostat. Either way, we carry the parts.
Sewer smell inside the RV usually means a failed tank valve seal, a cracked vent line, or a dried-out P-trap. It doesn't go away on its own, and in a small space it gets bad fast. This one's worth fixing quickly.
Call 772-276-6465 or submit an estimate request online. Tell us what's going on - pump not running, heater won't light, water under the rig. We'll give you a time window, usually same or next day for most of the Port St. Lucie and Treasure Coast area.
Our tech shows up with a stocked truck and diagnostic tools. We trace the leak, pressure-test the lines, pull the water heater cover, or check the pump - whatever it takes to find the actual problem. You get a written estimate before we start any work. No guesswork billing.
Most RV plumbing repairs are done in 1-2 hours. We carry Shurflo and Flojet pumps, Suburban thermocouple kits, PEX tubing, push-fit fittings, and Dometic/Thetford toilet seals. If we have the part, it's fixed that day. No ordering, no "come back next week."
Plumbing emergencies don't wait for Monday morning. We answer emergency calls around the clock across St. Lucie, Martin, and Indian River counties. A burst line in the middle of the night is a real problem - we'll get someone out there.
All our technicians are RVIA certified through the Recreation Vehicle Industry Association and hold current Florida state licenses. When someone's working on your water heater or LP gas lines, credentials matter. We're happy to provide proof before we start.
We warranty all labor for 90 days. If something we repaired fails in that window, we come back and fix it at no charge. Parts carry the manufacturer's warranty on top of that. You're not calling us back in 30 days to argue about a repair that didn't hold.
Water pump died on us at a campground in Stuart on a Friday afternoon. They sent a tech out Saturday morning, had a replacement pump on the truck, and we had running water by noon. That's exactly what mobile service should be.
Hot water heater pilot wouldn't stay lit for the whole winter. Tech came out, said it was the thermocouple, had the part right there, done in under an hour. Price was fair. Would have cost me three times as much at a shop to tow it in.
Found a leak under our travel trailer that had been going on for weeks - two fittings behind the belly wrap. Fixed both same day, showed me exactly what was wrong, and explained how to spot it early next time. Honest and thorough.
Most RV plumbing repairs run $80-350 depending on what's wrong. A water pump replacement is usually $120-220 parts and labor. Water heater repairs run $150-350 depending on whether it's gas or electric and what the actual fault is. Pipe leaks and fitting repairs come in at $90-200. We always write up an estimate before starting - no surprises.
A pump that runs but produces no water usually means the fresh tank is empty, there's a cracked or disconnected line before the pump, or the pump has lost its prime. We see this a lot on rigs that sat dry for a season. Less common causes include a seized impeller or a collapsed inlet screen. We trace it in about 20 minutes on-site - it's one of the more straightforward diagnoses we do.
Almost every RV plumbing repair we do is on-site. Water pump swaps, water heater repairs, pipe patches, toilet replacements, tank valve replacements - we carry the parts and tools for all of it. You don't need to tow anywhere. The whole point of mobile service is that we come to your campsite, driveway, RV park, or storage facility.
We work on Suburban and Atwood (now branded as Dometic) water heaters, which covers the vast majority of RVs on the road. Both gas and electric models. According to Dometic's product lineup, these units use standardized components - we stock common igniter boards, thermostats, anode rods, and bypass kits on the truck. If you've got something less common, call and ask - we'll tell you straight.
Common signs include water pooling under the rig after use, soft flooring near the sink or bathroom, a water pump that short-cycles (kicks on for a second then off repeatedly with no tap open), musty smell in the storage bays, and visible wet stains on the underbelly wrap. If your pump cycles on and off by itself with everything closed, that almost always means a leak somewhere in the system.
Yes. We replace gate valves, fix sensor issues, repair cracked fittings, and address bad drain connections. Smells coming from the tank area are usually a failed valve seal or a cracked vent line - both fixable on-site. Tank valve replacement runs $100-200 depending on the fitting configuration. If your sensors haven't read accurately in a while, we can check those at the same visit.
Most repairs finish in 45 minutes to 2 hours. A water pump swap takes 45-60 minutes. Water heater repairs run 60-90 minutes depending on the fault. Pipe leaks vary - a simple fitting repair is 30 minutes, a burst line under the belly wrap can take 2-3 hours. We'll give you a time estimate when we do the diagnostic. No vague "a few hours" windows.
A pilot that won't stay lit on a Suburban or Atwood unit almost always points to a dirty or failed thermocouple, a faulty piezo igniter, or a blocked orifice. In Florida's humid climate we also see corrosion on the igniter board contacts - the salt air off the Treasure Coast accelerates that. This is one of the most common calls we get and usually runs $80-150. We carry Suburban thermocouple kits and igniter assemblies on the truck, so it's typically a same-visit fix.
