Question: I HAVE WHAT APPEARS TO BE A PLUMBING DESIGN PROBLEM AT MY HOUSE. THERE IS A DRAIN PIPE FROM A WASHER THAT FEEDS INTO A DRY WELL. THE WHOLE THING STARTS WITH A WASHER THAT FEEDS INTO A 1-1/2 INCH STANDPIPE WITH A TRAP AT THE BOTTOM. THEN A BASIN SINK WITH A TRAP FEEDS INTO THE PIPE. THEN A GARDNERS SHOWER WITHOUT A TRAP FEEDS INTO THE PIPE. THEN THERE IS A TRAP AND ABOUT A 55 FOOT RUN OUT TO THE DRY WELL. THERE ARE NO VENTS. THE PROBLEM IS THAT WHEN THE WASHER EMPTYS OUT, THE SHOWER FLOODS WITH ABOUT 3 INCHES OF WATER. I THINK THAT THAT MUCH WATER CAN NOT GO DOWN THE DRAIN VERY QUICKLY, BUT I WOULD AT LEAST LIKE THE SINK TO FILL INSTEAD OF THE SHOWER.
Answer: Sounds like the 55' is blocking (ed) up, or the dry well is full or the pores of the ground won't allow absorption. New dry well and line to it will probably fix this. A 1 1/2" line is more than enough to drain a washer. Put the washer hose in the sink as long as the sink doesn't overflow, that will slow the flow down so it doesn't come up in the shower. And before ya do any of this, turn off your caps lock!
