Service call in a large kitchen. Went on the roof and found a Studor filter the size of a hockey puck. Thing must have been ten plus years old. The large dish washing station near the toliet was venting though the stool. Would a pluged vent pipe cause water to bunce in the stool so bad it over flows? I jetted the line to the trap and down from the vent. The lines seemed clean. Do these filters work? and what happen ten years after there 2 year life span.
No announcement yet.
