Water pump prime loss during winterization is commonly caused by faulty check valves, air leaks in suction lines, or worn pump components. This comprehensive guide covers diagnosis, repair procedures, and preventive maintenance for RV water systems.
Cracked Dometic AC covers can be temporarily repaired with plastic welding or epoxy, but replacement is recommended for long-term durability. Roof vent caps are typically made of UV-resistant ABS plastic and can be replaced individually for $15-30.
Black tank flush not accepting water usually means stuck check valve or debris in the spray nozzle. Try direct water connection without regulator, or clear valve with compressed air.
Fresh water tank drips that slow overnight are usually near the tank top - check fill hose, vent, and overflow connections. Inspect accessible areas before dropping the underbelly.
Protect your RV from freeze damage with this comprehensive winterization and de-winterization guide.
When your RV water pump runs constantly but produces no water after de-winterizing, you likely have air in the lines or a priming issue. Start by checking all faucets are closed, then prime the pump by opening the closest faucet to the pump until water flows steadily.
Lukewarm water from your RV heater is typically caused by a failing heating element, sediment buildup, or thermostat issues. Most problems can be fixed by replacing the heating element, flushing the tank, or adjusting the thermostat.
Lift slideouts for floor repair using bottle jacks and blocks under the extended slide frame, or a come-along from inside. Never rely solely on hydraulics - always use mechanical blocking.
For RV showers, the Symmons Temptrol and Phoenix PF213200 are top mechanical thermostatic mixing valves. Digital models like the Kohler DTV+ require significant electrical modifications that aren't practical for most RV installations.
When your RV's washer P-trap dries out from non-use, gray tank odors will escape through the drain. Add water monthly, install a trap primer, or use a P-trap cap to maintain the water seal and prevent sewer gases.
For Ford V10 RV engines, Wix 51348 (also sold as NAPA Gold 1348) offers the best balance of quality and value. Premium options like Mobil 1 M1-210A provide extended service intervals for RVers who drive long distances.
60 PSI is at the high end of acceptable but generally OK for modern RVs. If your regulator is set to 50 but reading 60, the regulator may be failing or gauge inaccurate. Compare with another gauge and consider an adjustable regulator.
Sanitize your RV water tank after extended storage, especially after hot Arizona summers. Use 1/4 cup bleach per 15 gallons, let sit 4+ hours, then flush thoroughly.
Low water pressure with 40 PSI at regulator indicates restriction downstream. Check inline water filter, city water check valve, and any winterization valves. Pump running on city water confirms restriction.
Replace your broken Oxygenics mount with a universal adjustable mount like the Dura Faucet DF-SA130-WT or ShowerMaxx Premium mount. Upgrade to a flexible stainless steel or kink-resistant hose for better performance and longevity.
