    Overflow Standpipe
    New washing machine with plastic drain hose perhaps too long for a 2'' diameter 36'' high copper stand pipe. Water over flow from stand pipe when washing machine is draining? What happen? Please help.

    If you have water coming out of the stand pipe the machine is draining that means that you have an obstruction in the line some where between the stand pipe and where that lines connects to the house main sewer line. This means it will have to be un cloged with a sewer cable.

    It's a Whirlpool washing machine with an unusual long plastic drain hose. It is so long that we have a difficult time to insert this hose into the standpipe. The last machine we have was a Maytag and it has a rubber drain hose which fits appropriately into the standpipe.

    Can I reduce the plastic drain hose by cutting the extra length off?

    Thx.

    I tend to agree at this point.
    The copper standpipe... is it 2" outside diameter? Is it the same for the trap?

    If the drain didn't back up for the old washer, it shouldn't for the new. Talk to the dealer. The longer hose could be combined with a stronger pump for discharging into a higher drain. Some of the newer washers discharge the water much faster. You could try coupling the hose tight to the stand pipe, or restricting the flow to slow it down.

    If you connect the drain hose tight to the stand pipe you will create a problem of syphoning as the washer drains. While the washer drains with no air entering the stand pipe that creates a long syphon line that extends below the water in the washer and if it can not get air to break this syphon, as the washer starts to fill for the next phase of the cycle it will continue to syphon out the water that is going into the washer.

    Now there is a fitting that is called an anti-syphon valve. It connects solid to the stand pipe and then the drain hose connects to it. As the washer pumps out a valve is pushed up by the air pressure and after the water has drained the valve opens to break the syphon.
