Frequently Asked Questions
Q: How do I know if my wet end assembly needs replacement?
A: Signs include reduced water pressure, visible leaks around the pump housing, pump running but no water flow, or the pump cycling on and off frequently. If your pump is otherwise functioning, a worn wet end is likely the issue.
Q: Can I install this myself?
A: Yes. Most RV owners can replace the wet end assembly with basic tools. You'll need to shut off power, drain the system, and unbolt the assembly from your existing pump motor. Installation typically takes 30–45 minutes.
Q: Will this work with my P500 pump regardless of year?
A: This OEM assembly fits all standard Dometic P500 series pumps. Verify your pump model before ordering. If you're unsure, our team can help confirm compatibility.
