"Brilliant replacement if your kitchen sink (as mine) doesn't empty very quickly and water from the washing machine comes up into the sink.
I tried the usual route of use chemicals to unblock the pipes (including having a getting plumber to the same using trade-only acid based stuff# but the washing machine waste was still coming up into the sink.
Looking at the old P-Trap I could see the waste pipe from the washing machine was going up and over the cupboard divider and down into an appliance adapter - BUT the appliance adapter was at the same level as the outflow for the sink waste, so it sounded reasonable to me that the water from the w/machine was going up the sink because it was one of the easier places to go #as there was no lower centre of gravity for the kitchen waste pipe#.
So, having just replaced the old P-Trap with this AND making sure the kitchen waste pipe IS LOWER #i.e. closer to the ground# than the w/machine waste I can now happily report both the kitchen sink not only clears much faster AND the w/machine no longer rises up into the sink!!
FINALLY, a solution to a problem that has been bugging me for a few years now #despite the advise of others that the old P-Trap having the w/machine at the same level as the kitchen sink waste was acceptable).
In short therefore if you believe you've blocked pipes AND you've tried/had them cleaned and the problem persists it's more likely that the kitchen sink waste needs to be lower than any inflow.
