💪 Enhance Performance with SHURFLO 94-800-03 Model 4008 Repair Parts - Check Valve Review

Ordered twice, both had the same alignment issue as the round valve was off center on one side was. This makes installation impossible as the misaligned plastic will prevent the part from sitting in place. The part number is correct so I believe this is a defective batch being sold.

I had a problem with my caravan where the fresh water tank was filling up even though it was connected to the mains water supply. The cause of the problem turned out to be a non-return valve in the fresh water pump, replacing it with this kit solved the problem. You can find the part online for half the price, but shipping is quite expensive.

Our motorhome had a pump running all the time and we were glad to know we could only buy this part. I replaced the pump diaphragm at the same time because I had a new one, but I'm pretty sure the check valve was the problem. Even with both parts it was less than half the price of a new pump and the motor was fine. I'm always happy to take an hour of my time to save fifty bucks.
