Kenmore 7278434 Water Softener Bypass Valve

Worked like a charm. Old manifold sprung a leak and no matter what I changed, it wouldn't stop. Swapped this in with silicone lubricant and not a drop leaking after a week. Far less frustration than I figured and worked like a champ. The bypass isn't quite as good as the original, still has a small amount of water that flows in bypass mode but it's manageable. Lot better than a new $500 softener.

Fixed the water softener!

Perfect fit for kenmore water softener

My water softener started leaking water into the tank and onto the floor of the garage. I tried replacing the o-rings on my bypass valve where it attaches to the water softener. Slowed it down but that was about it. Replace the entire valve and liberally coated the o-rings with o-ring lube. I had to buy some from Home Depot to make sure I got a good coat of the lube on the rings. Everything works fine now. Good product

I have the Whirlpool WHES33 LE33 water softener. One day on a whim just checked the salt level only to find the entire salt reservoir full of water. Deduced that water was leaking where the bypass manifold plugs into the softener. I thought O-rings right away and went ahead and wasted my time replacing all the O-rings only for it to continue leaking. Upon even further inspection, found a practically microscopic crack in the manifold assembly. Only visible while shining a light through the plastic. According to Whirlpool, the exact correct replacement is part No. 7370286 and it is no longer available, I would have to replace with the manifold that has threaded adapters. Well I wasnt looking to change out the in/out fittings so I continued my homework. Knowing all the different softener “manufacturers” are all using pretty much the same parts, I came across this “Kenmore” version. Well what do ya know, its a direct replacement for the Whirlpool one which is “no longer available”. My water softener is back on line with OE configuration.
