Trying to help out my senior neighbor with her washer drain. She said during 'drain' water was spilling back out over the top of standpipe..
I discovered that the drain pipe to the drain was only 1.5 inches diameter and my understanding is it should be 2" ? I dry fit this this morning but am concerned about 2 things (perhaps more, u tell me!)
1) This drain junction is cast iron and the entry of the washer drain is still only 1.5". Trying to avoid costing this lady a major repair can I run the 2" pipe right to within 2" of vertical drain and use a reducing union to drop to 1.5" before exit? The new sandpipe is 30" tall currently.
2) Is the run from my 2" trap at 17" too long and in need of a vent before vertical drain?
I thank you all on her behalf
