RV Valve & Fixture Replacement in Jensen Beach

RV faucets, valves, and plumbing fixtures aren't built to residential standards. They're lighter, cheaper, and designed for a vehicle that vibrates down the highway at 65 mph. That means they wear out faster than the fixtures in your house, and when they do, you need someone who understands the differences between RV plumbing and residential plumbing. Scott Marlins has been replacing RV valves and fixtures across Jensen Beach for over 10 years, and he'll tell you straight: the right fixture installed correctly lasts years. The wrong one creates problems within months.

Faucet Replacement

RV faucets are the most commonly replaced plumbing fixture we see. The original equipment faucets in most RVs are basic single-handle or two-handle designs made with plastic cartridges. Those cartridges wear out, the handles get loose, and eventually the faucet starts dripping or loses the ability to mix hot and cold water properly. In Florida's hard water, mineral buildup inside the cartridge accelerates this process.

When it's time for a new faucet, you've got options. RV-specific faucets from brands like Dura Faucet and Phoenix are designed to fit standard RV sink cutouts and use 1/2-inch connections that match most RV plumbing. But many of our customers upgrade to residential-grade faucets from Moen, Delta, or Pfister. These are better built, have ceramic disc cartridges that last much longer, and come in more styles. The tradeoff is that they sometimes need adapter fittings to connect to RV plumbing, and they're heavier.

We handle the full installation either way. That includes removing the old faucet, cleaning the mounting surface, installing the new unit with proper sealing, connecting the supply lines, and testing for leaks at every connection point. If you want a pull-down or pull-out kitchen faucet, we'll make sure the sprayer hose routes properly and doesn't interfere with anything below the sink.

Shower Valve Replacement

RV shower valves control the mix of hot and cold water going to the shower head. Most RVs use a single-handle mixing valve, and the internal cartridge is the part that fails. Signs of a failing shower valve include difficulty getting the right temperature, water that swings between hot and cold, low flow even with a clean shower head, or dripping when the valve is in the off position.

Replacing an RV shower valve requires access behind the shower wall, which varies by RV model. Some have an access panel on the back side of the wall, while others require removing the valve from the shower side. We've done this job on hundreds of RVs, and we know the access tricks for most common makes and models. A typical shower valve replacement takes 1 to 2 hours.

For owners who want a better shower experience, we can install upgraded valve assemblies with better temperature control and higher flow rates. Paired with a quality shower head (we like the Oxygenics brand for RV use because of its water-saving design), this upgrade makes a noticeable difference in daily comfort.

RV Toilet Replacement

RV toilets aren't like home toilets. Most use a foot-pedal flush mechanism instead of a tank-and-lever system, and they connect directly to the black holding tank below. The two main types are gravity-flush (the standard in most RVs) and vacuum-flush (found in some high-end coaches). Both types eventually need replacement due to worn seals, cracked bowls, or failing flush mechanisms.

Thetford and Dometic are the two dominant brands in RV toilets. Thetford's Aqua-Magic V is the most common model we replace, and the Aqua-Magic Residence (which has a residential-style profile) is the most popular upgrade. Dometic's 300 and 310 series are also common. We stock standard replacement seals and carry the most popular complete units on the truck.

The replacement process involves shutting off and disconnecting the water supply, unbolting the old toilet from the floor flange, cleaning the flange surface, installing a new wax ring or foam seal, bolting down the new toilet, reconnecting the water supply, and testing. Floor bolt patterns are standardized across most manufacturers, but we always verify before ordering if you're switching brands.

Bypass Valves and Shut-Off Valves

Water heater bypass valves are small but important. They allow you to route water around the water heater during winterization, so you don't have to pump 6 to 10 gallons of antifreeze through the heater tank. If your bypass valves are missing (some budget RVs don't come with them), leaking, or stuck, winterizing becomes expensive and messy. We install new bypass kits that include the valves, fittings, and mounting hardware.

Individual shut-off valves at each fixture are another upgrade we recommend. Most RVs leave the factory with no way to shut off water to an individual sink, shower, or toilet without killing the entire system. Adding quarter-turn ball valves at each fixture means you can isolate a problem while still having running water everywhere else. It's one of the most practical upgrades you can make to an RV's plumbing system.

We also replace main water line shut-offs, city water inlet check valves, and pressure regulators. These components protect your entire plumbing system from overpressure and backflow, and they're worth inspecting every year or two.

Why RV Fixtures Fail Faster in Florida

Between the hard water, the heat, and the road vibration, RV plumbing fixtures in Florida have a tough life. The combination of mineral-laden water running through plastic cartridges that are constantly expanding and contracting with temperature swings means you'll replace fixtures more often here than in cooler, soft-water states. The typical RV faucet cartridge lasts 2 to 4 years in Florida versus 4 to 6 years in northern states, based on what we see in our service calls.

Toilet seals are another Florida casualty. The rubber seal between the bowl and the flush mechanism dries out and hardens faster in the heat, leading to slow leaks that waste water and let tank odors seep into the bathroom. We recommend checking toilet seals annually and replacing them every 2 to 3 years as preventive maintenance. The seal itself costs under $15, and replacing it takes about 30 minutes.
