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.
Repair holes in RV grey water tanks. Covers temporary road fixes, permanent ABS patching, and polyethylene repair options.
Your 2-inch thick cabinet bottom and poorly routed PEX lines are classic examples of RV manufacturers prioritizing cost over space efficiency. These issues can be addressed through cabinet modification and PEX rerouting.
Troubleshoot house batteries dying while on 50 amp shore power. Diagnose converter, breakers, and connections to restore proper charging.
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.
Slideout rubbing wall with smaller bottom gap suggests drooping - worn lower rollers or adjustment needed. Inspect rollers, check mounting bolts, and look for floor damage underneath.
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.
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.
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.
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.
