We recently had the washer moved and a new 2" drain installed, but now we seem to be getting Suds overflow.
Break down:
Tapped into the main 3" a exit of house to sept tank i.e. right at the cast iron joint to PCV. run to sept tank about 10ft.
Distance from main to washer is 7ft, pitch was set at 1/4 in per foot, yes there is a 2" check valve, flapper type.
P trap at washer with 8 inch stack pipe.
Further FYI: top of stack pipe is about 12"~14" above main leaving house. We are not using any more/less soap then we have been, stillsame MFG.
Old system on other side of room is 1 1/2 copper with about a 20~24" stack pipe - never had this problem drains into other house sept sys. 3" copper, run to tank is about 30~40ft
I am wondering is stack pipe is not "long enough"? but extending would be a propential issue
Ideas?
Thanks
