Have you got the right size of discharge pipe?

So your outlet pipe can't cope with the volume of water the washing machine is chucking out. When you say there's nothing wrong with your outlet pipe, what have you checked? How far downstream?

Anything else discharging into the same run of pipe when the washer discharges?

We had a flooding problem once and unfortunately it had been on going for some time hidden by the vinyl flooring. Result was rotten floor boards and dry rot in the joists. On replacing the floor we found the culprit. When the house was being built some genius had dropped a wood screw down the discharge pipe. Over the next 10-12 years fine threads in the wash water had caught on this screw and finally built up enough the cause temporary blockage. Water could escape past it but it couldn't take the full flow.

Probably the same genius who didn't bother connecting the upstand pipe for the dishwasher when he heard we weren't having a dishwasher installed. The upstand pipe was there ok, under the sink clipped to the side of the cupboard, but when it got out of sight it didn't connect to anything. Poxy scumbag.

We had a similar problem which was identified as the top of the drain pipe was too low on the wall for the output flow from our new machine. A check of the owners manual mentioned the minimum height needed. Put the drain pipe 6 inches higher and we had no more problems with intermittent flooding.

This looks like it may be a good one. I shal check it out. Thanks

I was thinking this but was not sure how to go about it. Is there a connector for this sort of thing. What about syphon prevention.
