Sink drain pulling vaccum on boiler condensate trap

[Nintendofan]

is this an Ideal boiler in a new build property? My Ideal boiler gurgles as well in the utility room but as the boiler is fitted with a 75mm sealed trap according to the installation manual then this is fine.

Download the installation manual and read the section on the codensate drain and see if you come to the same conclusion as me.

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?

Did you check your boiler is factory fitted with a 75mm sealed condensate trap as shown in the Ideal installation manual? if so then you'll hear the bubbling but it wont empty the trap so is safe to leave as it is.

Yes it is.

It was ideal who said it shouldn’t do that…

my gas engineer who services it each year says its fine. Is your new build still under 2 years old? if so speak to the developer as ask the question.

I'm guessing the drain of the sink isn't connected to any soil stack with ventilation but connected directly to the outside sewer pipe. If this is the case then when the sink is emptied then the air being compressed from the waste water needs to escape somewhere and the route of least resistance is via the boiler.

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

Rang Ideal - they were helpful - they are coming to have a look at it. If it's done incorrectly least then I can throw that back at the builder!

Hi, did Ideal inspect this and suggest if it was correct or not?

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
