Review on ISpring F2WGB22BM 2-Stage Whole House Water Filter Set Replacement Pack, 4.5” X 20” With CTO Carbon Block And Iron & Manganese Reducing Cartridges, Compatible With WGB22BM, In White by Brandon Henry

We had this filter system installed by a plumber in July of 2021. It has been doing a great job of producing bottled water quality water from our well water. I did a recent filter change and one of the canisters would not seal. One of the O-rings looked to be stretched and was too large for the canister groove. I called iSpring customer support to inquire about getting a new O-ring. I spoke with SEAN and he promptly sent me new O-rings. I installed the new O-rings, requiring only hand tightening of the canister to attain a no leak condition! I am very happy with this filter system and with SEAN from ISpring support.
