Review on Fleck COMINHKR047408 FBA_60049 Replacement Bypass by Natalie Gregory

I bought two of these which fit perfectly and didn't leak the first time. First I tried replacing the o-rings on the old bypass valves but even with silicone grease I wasted my time. I wanted to confirm that they would fit control valves and clamps but couldn't find the dimensions between the two ports so I took a chance and assumed it might be the standard spacing. Everything was installed and I have since found that the control valves are a Fleck 5000 ProFloSE water softener and a WF20-56 (5600) water filter. Hope this information helps someone.
