Can someone help i have just plumbed in a new dish washer and washing machine but neither will drain the water out? I changed the bottle trap under the sink with a new one that as got 2 waste pipes on it but it does not seem to want to drain either. At the moment i have had to un couple them and use buckets?
I hope this doesn't sound stupid, but you did cut the end off the new drain stubs on the bottle trap, didn't you? Usually the ends are blanked, in case you didn't need to use it.
