Frequently Asked Questions
How do I know if my check valve needs replacement?
Common signs include weak or inconsistent bidet spray pressure, water dripping from the bidet nozzle when not in use, or complete loss of bidet function. If your toilet flushes normally but the bidet doesn't work properly, the check valve is often the culprit.
Is this valve difficult to replace?
Most RV owners with basic plumbing skills can replace this check valve. You'll need to access the water supply line behind or beneath your toilet, disconnect the old valve, and install the new one. Always turn off your water supply before beginning any plumbing work. The valve typically connects with compression fittings or quick-connect couplings.
Will this kit work on my Dometic 310 or 320 toilet without a bidet?
No, this check valve kit is specifically designed for 310 and 320 Series toilets equipped with the bidet feature. If your toilet doesn't have a bidet spray nozzle, you don't need this part. This valve is part of the separate bidet water supply system.
What causes check valves to fail in RV toilets?
Check valves can fail due to mineral buildup from hard water, debris in the water line, freezing damage if the RV wasn't properly winterized, or simply normal wear over time. The internal spring and seal components eventually degrade, especially in systems that see frequent use or sit unused for extended periods.
