Notes about our home repair.

The master bathroom and downstairs bathroom use Price Pfister 7G-1H and 7G-1C water faucets.

Turn off water below the faucet. (Of course! But also so you can do the next part.) Then open the tap when you unscrew the step. A closed tap seems to create a vacuum or hydraulic counter pressure.

The bigger O-Ring is Danco's #30 (AS568B# 018). It's 7/8" OD x 3/4" ID x 1/16". (But their #40 is very close at 3/4 in. OD x 5/8 in. ID x 1/16 in.)

The inner O-Ring is Danco's #8 (AS568B# 110). It's 9/16" OD x 3/8" ID x 3/32".

A leak at the faucet is probably caused by the seat washer. The Danco 80359 (fits 3H-8H/C) seems to work.
