Bath without anti vac trap

[Mgrant]

Hey I've got a bath to fit that happens to be on the end of a waste/ soil pipe run. The bath has come with a waste and trap all connected up. However the trap is not anti-vac, will this be a problem anything I can do to over come this?

Quite possibly, best to insert a mcalpine antivac tee/ socket which fits inline.

Fit an Aav above spill over level

This could fit just after the trap?

There is a 2 inch air vent on the run this tees of the run between the toilet and the bath waste. It's an internal concealed stack.

Yes, no problem after the trap.

Got a link to one of these anti vac sockets? Never seen one before.

i wouldnt worry baths very seldom empty the trap as the shape means there is a lot of run of water which refills the trap even if the initial flow empties it if yoyur not having problems i'd leave it

It's a new install so don't no if there ll be a problem
