We live on the 2nd floor of a 3 floor condo building. The washing machine
is drained by the hose being stuck into a pipe that diagonally sticks out of
the wall about 4-6 inches above the top of the machine. The problem is that
no matter what we try, the water backs up in that pipe and comes pouring out
the top when the machine drains. We've tried clamping sections of the hose
to try and slow the volume of water draining but we almost need to clamp it
off completely otherwise it still overflows. We've tried using lesser and
lesser amounts of detergent thinking maybe it's the suds that are building
up in the pipes and backing the water up but it makes no difference. We've
had several machines in here over the years and the problem happens with
each of them. Every couple of months we're able to compress and tape part
of the machine drain hose and get it set just right so it drains without
overflowing. However it keeps coming back.
Anybody have any ideas that don't involve ripping down walls floors and
ceilings or paying a plumber $500 to dig through the system?
The easiest thing to do first is snake out the line in the event it's
clogged. If you still have problems, it could be a problem in the vent
line going up to the roof. It could be clogged and can be snaked from
Another thing you can try to do is extend the drain pipe up about 2
feet. This will do 2 things:
1) Allow more water volume in the drain pipe, decreasing the chance of
2) The pump should drain a tad slower because of the added height it
has to push the water up. This should not pose a problem to the
washing machine because most washers can push water up a max height of
Just make sure the drain hose is long enough for the added height.
Otherwise you can buy a drain hose extender.
It should be fairly easy to extend the pipe up. You mentioned it comes
out diagonally. Just buy a 45 or 30 degree elbow and a short length of
PVC pipe. Glue it together, then attach it to the existing pipe with a
no-hub coupling. This will make it easy to remove in the event it you
notice it still overflowing. ( If you have PVC coming out of the wall,
do not glue the extension otherwise you cannot remove it, just use the
i would snake the line, probably a lint clog.
dont muck around a big flood with a patch job in your unit might put
you on the hook if another unit gets water damage.
snake the line.............
Any unit below yours having an issue????
