Washing machine drain overflows by wall where discharge hose goes in
Hi, I am having a problem where the washing machine overflows when in the spin cycle and water comes out the drain pipe that goes in to the wall. This is where the discharge hose goes into. House is older built in 1970. Drain pipe is 1-1/2 copper. I am aware of hearing that my newer machine pumps out faster than the old maytag. Also the older copper pipe should be 2 inch or larger. The problem is that it connects in the wall and goes down to the cement floor and into cement into iron sewer pipe. Also down at the floor other side of wall I opened in closet and I see where the kitchen drain from the sink t-s into the same pipe. I tried running a garden hose , ran fine in the wall drain for the wash machine for 30 min no overflow. If you run 1 load no problem but more than 1 back up and overflows. I would rather try to avoid disturbing all the copper connections as they are not leaking. I heard that the new machine has a water pump that pumps more volume faster than the old. There is no room for a laundry tub in this room as it is small. Can a restricter be put on the discharge hose without damage to the wash machine. The machine is a heavy duty large capacity in a single dwelling home. I should have bought a small machine instead but anyone have any ideas, thank you
Stand pipe leaks behind washer.
Everyone has good ideas, thanks, but my concern is this. I have a 1-1/2 copper drain pipe that comes down the wall from a double bowl kitchen sink dishwasher connection. They both by the way never have a problem and divert into the same copper drain into the cement floor that the washer does and then into the iron sanitary pipe. The washer ties into the same copper connection at the basement floor in the laundry room. I do not have room for a tub too small and other side of wall is outside or family room inside, no good. This makes me feel that the washer gets too powerful of a discharge rather then my old maytag that broke. I feel if I close off the system at the top of the stand pipe connection that the water pressure will build up , go up the wall (copper pipe)and into the kitchen sink possibly overflowing? Possible? What about this? Could I connect a rubber connector with hose clamps and add some pvc with a-- t. then I could divert downward a 1-1/2 pvc pipe to the floor drain between the washer and dryer. This floor drain is the same as sanitary which is utilized in older homes as this 1970 built. Good idea or bad as it could create a possible flood and or a floor flood problem. Other drains are fine. By the way the copper pipe in wall that the stand pipe goes into is about 5 feet long and drops into cement into iron pipe. Behind a ceramic shower so I would rather not break open the wall to install a larger 2 inch pipe as a total shower remodel would be involved here. Thanks all
