re flooding

A while back  was saying about the outflow of my washing machine flooding.

Just an update. I looked into it and the problem was that the pump was
just too fast for the pipe to cope without overflowing.

It only happened when either the machine was not very full OR when the
materials washed did not hold the water ie nylon etc.

I have now put a SPONGE  seal between the hose and the pipe to prevent
the water overflowing the pipe and it is working OK even with a totaly
empty machine discharging.

Thanks for the help.
