Perlick 525 forward seal faucets are great. The forward seal reduces sticking in the lever, reduces bacteria growth in the faucet, and generally offers a smoother pour than a standard faucet. Unfortunately, many owners of the 525 series faucets have experienced leaking, which has caused much frustration. Perlick offers a rebuild kit, but many users have reported that the rebuild kit only fixes things temporarily or sometimes the rebuild kit doesn’t resolve the problem at all.
I’ve rebuilt 6 Perlick faucets, three I bought new that leaked for me, and three more that I believe were leaking when I bought them second hand. None of them leak now. Here’s how to repair yours.
