PROBLEM

REPAIR CHECKLIST

Continuous bubbler flow.

Insure that push button is not obstructed

and springs back to normal position.

Remove four screws, which secure

plastic diaphragm block to brass valve

body. Pull plastic and rubber diaphragm

assembly out of valve body. Locate tiny

hole in rubber diaphragm just under lip

of plastic part. Clean debris from this

hole. Inspect valve seat for grooves. If

seat is worn, replace with stainless steel

seat (newer models) or replace valve

(older models, integral brass seat).

If valve seat was OK and diaphragm

holes were free from debris, inspect

rubber button located at center of

floating steel disc in valve diaphragm

block assembly. If button is worn, turn

disc over or replace disc.

If diaphragm and seats are in good

condition, stretch spring slightly. Spring

is located behind floating stainless steel

plate.

Insure that air bleed port on valve

plastic block assembly is not plugged.
