Water Leaking Into Fresh Water Holding Tank
The fresh water holding tank is filling up with water due to a low volume leak and I suspect it's not the Watts brass three way ball valve used to divert water to the fresh water holding tank while connected to city water. I am thinking it might be the check valve in 4008-101-E65 Surflow water pump. I don't think this pump has a replaceable check valve, so my questions are:
a. Would you install a shutoff valve in the fresh water holding tank fill line? This adds a winterizing gotcha if I fail to remembered to open it during the winterizing procedure. However, its an easy fix!
b. Install an in-line check valve on the suction side of the pump? If so, what check valve type/brand would you use?
c. Replace the pump?
d. Is there another point in the fresh water plumbing that could be causing this problem?
Thanks in advance for your help.
