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.
Troubleshoot and fix random grey water tank blockages. Covers causes, cleaning methods, and prevention for smooth RV waste water drainage.
When your RV black tank overflows through the vent at less than full capacity, it's typically due to incorrect tank positioning, vent pipe placement, or sensor issues rather than blockages. The tank may be installed at an angle or the vent pipe may enter too low on the tank.
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.
Reversed heater lines cause hot dash air while driving because coolant constantly flows through heater core. Diagnose by feeling hose temps, fix by swapping hoses or adding shutoff valve.
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.
If you've already replaced the valve multiple times and the foot pedal continues to fail, replacing the entire Dometic 310 toilet is often more cost-effective and reliable than repeatedly replacing individual components.
With a macerator pump, RV-specific toilet paper is not necessary. The macerator grinds paper with waste. Single-ply or septic-safe regular toilet paper works well - Scott 1000 is the most recommended. Avoid ultra-plush multi-ply and wet wipes.
RV toilet dump valves stick after winterization due to lack of moisture and seal drying. Apply water-based lubricant or silicone spray to the valve mechanism and seals before and after winterizing to prevent sticking.
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.
Thor Ace has both macerator and gravity dump. Look for valves in the wet bay that direct flow to one or the other. Close the valve to the outlet you are not using. Some setups have both connected - gravity works by default, macerator works when pump is on.
No hot water pressure with working cold is usually stuck backflow preventer in hot water outlet. Located near tank connection behind water heater. Tapping the device or manipulating the spring frees the stuck valve.
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.
