Review on 🚰 Moen 9601 ChoiceFlo Compatible Replacement by Maryland Hess

Revain's price is light years better than the local plumbing supplier. This is an original product from the original manufacturer and not a counterfeit. During installation I found that the instructions are not the easiest. Shut off the water supply to the filter, and then open the drain to relieve internal pressure. Remove the old one by simply unscrewing it. Purchase potable silicone grease and apply to the o-ring, then install the new block. Enter easily. By following the instructions and leaving pressure in the system, I've found removing and reinserting the block almost impossible. Make sure the filter is not pressurized - it is fully pressurized to prevent leakage. This prevents easy removal.
