Picture of a Grohe Sinfonia lav faucet.

: I installed a new sink and a price phister faucet. The problem I am having is a leak at the rubber gasket right above the friction washer. The gasket that came with the faucet was too big not allowing the top flange of the gasket to go into the 1 3/4 inch opening. I bought a new gasket that fit perfectly. Both gaskets would not seal at the rim of the sink and if I tighten it as much as I could then the water would leak between the rubber gasket and the brass threading on the assembly. I was thinking of trying silocone to seal the rim and the threads. Is this standard practice? or am I doing something wrong.

I use plumbers putty on the sink to drain ring at the top end, if the sink is steel or china. If Marble, I use Silicone. On the brass threads where the gasket is below, smear plumbers putty on the threads. It doesn't say to do this on the directions, but I always do it. You know why. Terry
