[Home](/) 3. [Services](/#services) 5. RV Plumbing Repair # RV Plumbing Repair & Service From leaky faucets to full system overhauls — expert RV plumbing repair from Clean Slate RV Repair. We handle full-spectrum RV [plumbing](/services/plumbing): fresh-water systems, gray and black tanks, PEX rerouting, valve replacements, pressure testing, and leak detection. Every fix includes precise diagnostics — using flow meters, infrared thermography, and pressure gauges — to ensure watertight seals and optimal flow rates. RV [plumbing](/services/plumbing) is a world of its own — PEX lines, water pumps, holding tanks, check valves, city water connections, and winterization systems all need to work together flawlessly. When something goes wrong, you need a technician who knows RV plumbing inside and out. No shortcuts, no surprises — just reliable, code-compliant [plumbing](/services/plumbing) that keeps your rig functional and dry. Whether you're dealing with a mysterious leak, low water pressure, or a pump that won't prime, give us a call. ![RV technician diagnosing and repairing plumbing connections inside a recreational vehicle](/assets/plumbing-diagnostic-CQkpxIXM.jpg) ## Common RV Plumbing Problems We Fix RV [plumbing](/services/plumbing) systems are compact, exposed to temperature extremes, and constantly vibrating down the road. Here are the most common issues we see: Leaking fittings and connections: Road vibration loosens PEX crimp rings, SharkBite fittings, and threaded connections over time. We pressure-test the system to isolate leaks and repair them properly — not with tape and hope. [Water pump](/services/plumbing) issues: Pumps that won't prime, cycle constantly, pulsate, or have lost pressure. We diagnose the root cause — whether it's a failed check valve, air leak in the suction line, or a worn pump diaphragm. Frozen or burst pipes: Massachusetts winters are brutal on RV [plumbing](/services/plumbing). We repair freeze damage including burst PEX lines, cracked fittings, and damaged [water heater](/services/water-heater-service) tanks. Holding tank problems: Gray and black tank valves that won't open or close, tank sensors that read incorrectly, and drain valve leaks. We repair or replace gate valves, flush systems, and troubleshoot sensor issues. Low water pressure: Caused by clogged filters, partially closed valves, kinked lines, or a failing [water pump](/services/plumbing). We trace the system to find and fix the restriction. ### Need help with rv plumbing repair? Give Phil a call or send us a message — we'd love to help. [Call Us](tel:+15083333302)[Send a Message](mailto:cleanslaterv@gmail.com) ## Our Diagnostic Approach RV [plumbing](/services/plumbing) problems can be tricky to locate — water travels, and the source of a leak is often far from where you see the damage. Our diagnostic approach is systematic and thorough: We use pressure gauges to test the entire freshwater system for leaks, flow meters to verify pump output, and visual inspection to trace every line from the water inlet to each fixture. For hard-to-find leaks, we use infrared thermography to detect moisture behind walls and under floors without cutting into anything. This saves time, money, and your RV's interior. ![Technician performing RV winterization service, blowing out water lines with compressed air in autumn](/assets/plumbing-winterization-BQ3SvDdt.jpg) ## Winterization & De-Winterization Proper winterization is critical in New England. We provide complete winterization services that protect every component of your [plumbing](/services/plumbing) system from freeze damage: We drain the [water heater](/services/water-heater-service), bypass it, blow out all water lines with compressed air, and add non-toxic RV antifreeze to all traps, drains, and holding tanks. We also protect the [water pump](/services/plumbing), city water inlet, and exterior shower connections. In spring, we de-winterize and pressure-test the entire system before your first trip — flushing antifreeze, sanitizing the fresh water tank, and checking every connection for leaks. ![Professional PEX plumbing system installation inside an RV with accumulator tank and water filtration](/assets/plumbing-pex-upgrade-CSWr-NXq.jpg) ## PEX Rerouting & System Upgrades If your RV has chronic [plumbing](/services/plumbing) problems — repeated leaks, deteriorating polybutylene lines, or inadequate flow — a partial or full replumb may be the best solution. We reroute and replace [plumbing](/services/plumbing) using modern PEX tubing with proper crimp or clamp fittings. We can also add features like accumulator tanks (to reduce pump pulsation), whole-system water filters, and hot water recirculation loops. ## Pricing & What to Expect Our labor rate is $165/hour. A one-time $125 service call fee applies on your first visit only — that includes a complete [plumbing](/services/plumbing) diagnostic. From there, we provide an upfront estimate for any repairs needed — from simple fixes to full system replumbing. Every repair is pressure-tested before we leave — no callbacks, no leaks. ## Proudly Serving the South Shore, Southeastern Massachusetts & Cape Cod Based in Carver, MA, we provide mobile RV rv plumbing repair across Plymouth, Bristol & Barnstable Counties and surrounding areas.
