[maintman2008]

I have a soil pipe that goes through the bathroom and would like to reduce down so I can fit a normal bath. how do I do this and what parts do I need to solve this problem and I have herd of a breathing cap if this can be fitted and solve my problem what is the shortest length can this be.

Need a lot more information than that, and preferably a drawing of what you mean.

If I were a gambling man, I'd be guessing that the soil pipe is currently running floor to ceiling, and he wants to shorten this using an aav below the bath at floor level.

whaaaa yer can't do that silly boy

it says so in the book (dia made me read it )

Yes, that's what I assumed too, minumum size for air admittance valve is 3" and it must be sited above the spillover level of the highest appliance (Basin)

Don't shoot the messenger

so what about the aav's that can go below spillover level ?

Thus, op, if you want to get that bath in, you're going to have to relocate the soil pipe either along the wall somewhere or (more likely) outside!

Which ones are those?

floplast.

A1 approved in accordance with BS EN 12380 - can be installed below the flood level of connected appliances.

but 200mm above the highest wet entry.

That is interesting.

Now I wont feel as guilty for having installed standard AAV's beneath the worktops of fitted furniture for the last God knows how many years
