Yeah said to add a one way valve or a tundish. I said a tundish is no good as it lets foul smells back into the room. So the plumber fitted a one way valve today
Hi yeah I've asked the question to the builder it's under 2 years. They keep bringing back in the plumber to try different things.
How they are on about ripping my cupboard out to inspect the waste pipe :(
Air admitance valve didn't work. still pulling through air. Someone else seems to think the drain below the sink may be blocked - does that make sense?
Ah thats a good idea!
Actually found a u bend with a valve built in - this will save having to pull out all the glued sections which go into the waste

Thanks for heads up about waste pipe!
The one coming from the top to bottom is the trap for the sink into the drain. Before the trap it has a washing machine connected and a double sink.
The one coming from the left os the boiler condensate overflow
Hi,
When I drain the sink in my kitchen I can hear the boiler bubbling, it's the condensate trap pulling water down the overflow pipe into the drain which goes into the same drain as the sink.
Is this normal?
Yeah they are. I rang the head office of the plumber company and they said they don’t do residential customers. I’ll try and speak to one of them. You reckon they could do a job on the side for a bit of cash? They’d do all the certificates etc?
