With recent home purchase we inherited a LifeSource whole house water treatment system with sediment prefilter. Online reviews are widely spaced from wow to ugh. First order of business is the prefilter leaks, not from the canister seal, but from the bypass mechanism above it (pic). Called LifeSource and their solution is to come out and look at it for about $120. Ugh. No markings on the prefilter as to manufacturer. I'm hoping LifeSource sourced this prefilter from another vendor. They wouldn't tell me. The canister takes a 20" long filter. Canister diameter is about 3.5". Can anyone ID this prefilter?
