I have a washing machine upstairs. The discharge hose is placed in the top of some 2" ABS pipe. That pipe then drops about 14' to my basement floor, then runs along the floor for 5', ending in a hole in the floor. (The house is from 1955, so that hole in the floor is almost certainly intended to be used as a washing machine drain).
When the washing machine empties, the water properly flows through all the pipe and into the drain. Eventually though, the water starts to back up onto the floor. The floor is sloped towards the drain, so this isn't catastrophic, but I'm wondering if there is any way to reduce the flow rate of water entering the floor drain?
- increasing the pipe to a 4" or 5" pipe, then reducing the pipe at the drain end down to 1/2" or so - using the pipe as a sort of basin.
- Emptying the pipe into an actual basin that can hold the water, then having a smaller hose/pipe drain from that basin into the floor drain. Pretty much the same as option #1.
Any other suggestions? Is there any way to change the rate at which the washing machine pumps out water? I think if I could cut that in half, the problem would be solved.
