Re: Washing Machine Stand Pipe Overflowing
Typical pipe diameter is 2", and no, your garden hose won't usually overflow the stand pipe because it doesn't have the volume that a washer does during discharge.
What is the height of the stand pipe? It should be at or just above the level of the washer, a few inches low can make a huge difference in performance. The purpose of the stand pipe is to give the water somewhere to collect while the drain catches up to the discharge rate of the washer.
