What exactly gets fixed in RV plumbing service?
Water heater swaps, faucet replacements, pump replacements, and leak diagnostics are our bread and butter. We pull out failed Atwood or Dometic water heaters and install matching units. We replace corroded kitchen and bathroom faucets with durable Shurflo or OEM equivalents. Fresh water pumps that won't prime get swapped with tested replacements. When you've got a mystery leak, we use pressure testing equipment to find where water is escaping - under cabinets, through wall penetrations, or at tank connections. Gray tank valve repairs and black tank seal replacements happen regularly. We also chase and repair pinhole leaks in PEX or copper runs, often caused by vibration, corrosion, or age. Average turnaround on straightforward jobs is same-day.
A Forest River Sunseeker owner rolled in with a water heater that wouldn't heat above 90 degrees. The Atwood unit was 8 years old and corroded internally. We quoted a full swap - $1,200 including a new Dometic equivalent and full system flush. While we were there, the customer mentioned a slow drip from under the kitchen sink. Pressure test revealed a micro-crack in the cold water supply line behind cabinetry. We re-routed with new PEX, tested everything to 60 PSI, and gave them a working, ice-cold water system again. That's plumbing repair in context.

What are the most common RV plumbing problems?
Water heater failure, low water pressure, and mystery leaks top our call list. Water heaters fail because they sit unused for months, mineral buildup clogs heat exchanger passages, or
Mineral and sediment buildup in water heater
Pump cavitation from air in lines or dry-run
How much does RV plumbing repair actually cost?
Pricing is flat-rate by phone, no surprises. A water heater swap runs $1,100-$1,600 depending on whether you keep your old unit or upgrade from Atwood to Dometic. Faucet replacement costs $250-$450 per unit including the ca
Bad gas valve, pilot module, or thermocouple. Atwood and Suburban each have their own failure pattern.
Air leak somewhere on the suction side, or a failed diaphragm. We find it with pressure testing.
How fast can you get to my RV if something breaks?
In Florida and Idaho core areas, we target 2-4 hour emergency response. Because we're mobile-only - no shop, no waiting room - we roll directly to you. We carry common parts: Atwood and Dometic water heater units, Shurflo pump assemblies, faucet cartridges, sensor probes, tank valves, and pressure-test gear. Most emergency calls we take same-day. If it's a simple fix - dead pump, clogged line, bad sensor - we often resolve it in under 2 hours and you're back on the road. Longer jobs (full heater swap, tank valve disassembly) might run 4-6 hours. We also work with a nationwide partner network for RV owners outside our service footprint, so if you're traveling and your water system fails in Colorado or Louisiana, we can connect you with a certified mobile tech.
A Tiffin Allegro owner broke down at a Florida campground with zero water pressure mid-afternoon. Their Shurflo pump had burned dry. We got there in 2.5 hours, diagnosed the issue (air in lines, pump seized), pulled the pump, flushed the system, installed a rebuilt Shurflo unit, and pressure-tested the whole rig. Customer was back filling tanks and showering by 5 PM. No waiting for a dealer appointment. That's mobile repair working as designed.

What happens after you fix my RV plumbing?
We pressure-test the entire system to 60 PSI before we leave, provide a 90-day workmanship warranty, and give you documentation of what was done. Every water line gets pressurized. Every connection gets checked for drips. We document photos of work, parts installed, and test results. You get a receipt listing each component replaced or repaired, serial numbers where applicable, and the warranty terms. That 90-day window covers any failure traceable to our install or repair - if a new faucet cartridge leaks, we replace it free. If a newly installed pump fails, we swap it. Parts manufacturer warranty runs separately (usually 1-2 years), and we register Dometic components in your name so you own the coverage. We also give you a brief written rundown of what failed and why, so you know whether to expect the repair to hold long-term or if a full system overhaul is coming.
A Coachmen customer had us replace a gray tank valve. We pressure-tested the entire gray system, documented the old valve's corrosion, installed the new one, tested again to 60 PSI, and provided a photo summary. Thirty days later, customer called - valve was weeping slightly. We drove back, re-seated the connection, tested again, and confirmed zero leaks. No charge, covered under our 90-day warranty. That's the standard.
