RV Plumbing Repair in Washington

From a dripping fitting to a water pump that won’t prime, RV plumbing problems waste water and can quietly cause water damage. Poulsbo RV repairs the fresh, gray, and black water systems in travel trailers, fifth wheels, and motorhomes throughout Washington.

Signs Your RV Plumbing Needs Repair

Plumbing trouble shows up at the tap, the tank, or as a leak:

• Low or no water pressure at the faucets
• The water pump cycles constantly or won’t shut off
• Leaks under the sink, around fittings, or at the water heater
• Tank valves that won’t open, close, or seal
• A sewer smell inside the RV
• No hot water, or water that won’t get hot

Why RV Plumbing Fails

RV plumbing takes constant vibration on the road, which loosens fittings and cracks lines over time. The biggest seasonal risk in Washington is freezing: water left in lines and the water heater over winter expands and splits fittings, the pump head, and valves. Hard water builds up scale in the water heater and faucets. Gate and dump valves wear out and stop sealing, and the water pump’s check valve and diaphragm fail with age, which is why a pump may run nonstop or lose its prime.

Why Plumbing Leaks Shouldn't Wait

A small plumbing leak inside an RV is a slow path to expensive water damage, since the water soaks into the floor and walls before you ever see a puddle. A pump that runs constantly can burn out, and a freeze-split line discovered in spring means the damage already happened. Catching leaks and freeze risk early protects both the plumbing and the structure around it.

How to Keep Your RV Plumbing in Good Shape

• Winterize the water system fully before the first freeze
• Sanitize the fresh water tank seasonally
• Check fittings and under-sink areas for drips regularly
• Use a pressure regulator on city water hookups
• Lubricate dump valves to keep them sealing
• Drain and flush the water heater to clear scale

Why Does My Water Pump Keep Running?

A pump that won’t shut off usually has a leak in the system, a worn check valve, or a failing pressure switch. We test to find which and repair it.

Can You Repair a Freeze-Damaged Water System?

Yes. Freezing typically splits fittings, the pump, and valves. We locate every split, replace the damaged parts, and pressure-test to confirm there are no remaining leaks.

Why Do I Have No Hot Water?

It depends on whether your water heater runs on propane, electric, or both. We diagnose the heating element, gas valve, igniter, or thermostat to find the fault.

My Dump Valve Won't Seal. Can It Be Fixed?

Yes, worn gate valves are a common and straightforward replacement that restores a proper seal.

How Do I Keep My Plumbing From Freezing?

Full winterization with the lines drained and antifreeze in the system is the only reliable protection in a Washington winter. We offer winterization service.
