The Dometic water pump impeller is the rotating component that moves fresh water throughout your RV's plumbing system. If your water pressure is weak or the pump runs but water won't flow, a worn or damaged impeller is likely the culprit. This OEM replacement restores full water delivery to your faucets, shower, and toilet.

Frequently Asked Questions
Q: How do I know if my impeller needs replacement?
A: Signs include low water pressure even with a new tank, the pump running but no water flow, or visible cracks and wear on the impeller blade. If your PSH3000B3X pump is running but underperforming, the impeller is the first component to check.
Q: Is this a direct replacement for my pump?
A: Yes, this is the OEM impeller designed specifically for the Dometic PSH3000B3X pump. It's a direct drop-in replacement with no modifications needed.
Q: Can I install this myself?
A: Most RV owners can replace the impeller in 15–20 minutes. You'll need to access the pump (usually under the sink or in a cabinet), remove the pump head, and swap out the old impeller. Consult your RV manual or the Dometic pump documentation for step-by-step instructions.
