Review on 🏠 SHURFLO 94-800-00 Model 4008 Upper Housing: Complete Solution for Enhanced Performance by Daniel Shankle

This was a fairly easy job to fix our 2015 Navion 24G motorhome. The pump ran for a second or two every few minutes while water backflowed through the defective check valve. Recently the fresh water tank filled up when connected to the water supply and overflowed even though it was not set to the fill position due to the water flowing back into the tank through the pump. This fixed those issues. When I installed the pump for the first time after the repair, the pump did not turn off. It looks like there was a leak on the suction side sucking in air. I checked the connection and the washing machine was in poor condition and was probably the problem. This was not included, so there were no problems with the purchase. I better put a washer in the joint and wrapped the threads in teflon tape as an extra precaution. I made threads on both the suction side and the pressure side. This seems to have helped: the water flows well, better than before, and the pump turns off and stays off.
