washer drain overflowing
The washing machine in my garage goes into a 2″ abs line down to a p trap and then a T no hubbed into 2″ galvanized drain with about 15 ft. horizontal run into the main drain line the top of the T reduces to a 1 1/2″ galv. vent line which runs through the roof. The 2″ drain line also services the kitchen sink and dishwasher which have another 1 1/2″ vent. The washer drain has been overflowing lately. I have tried using a manual snake to clear the line as well as one of those gizmos you attach to a hose and it supposedly pulsates jets of water to clear the line. It seems to help for a week or two but then the problem begins again. I am not sure what more to do? Should I upsize the vent line to a 2″? Should I rent a power auger and run it through the line or should I seperate the 2 drains? Or?????? Please help
Probably restricted at the galvanized. You can remove the no hub to confirm this.
Also, if it’s a new washing machine then the pump may be putting out more volume than the original piping can handle. Seen it.
Remove the no hub. Clear the galvanized. Still have a problem, call a plumber.
