Just bought a new house, the bathroom has a boxed in soil pipe in the corner going up through the roof. I need to get rid of this intrusion into the room so that i can push the bath (narrow side) back against the wall and install a mixer shower on that wall.

I know i cant use an AAV as it will still nead to be above the flood point of the highest item in the room and i know the pipe cant go outside due to risk of freezing.

So what are my options?

hi
i have installed aavs and i just situate them just under the bath and not had any trouble but i may have installed them wrong if what you say about the flood point is correct? so i stand corrected
i dont see why you cant take the soil pipe out of the wall down the side of the house and re enter the drain system,depending on were they are situated,access etc
have you considered a saniflow system?

Not sure what a saniflow system is, i'm afraid (a bit new to all this!)

hi
your probarly best looking on the internet or screfix maybe
bob

Right, looked at saniflow and i'm not keen.

Anyone have any other suggestions of how i could get around this?

This must be a fairly common issue?

You are right, you should not use a AAV that will be lower than the highest sanitary ware.

Basically, you have three choices. Leave it where it is, put it outside (yes you can, lets face it, 3/4 of properties already have it outside and it was only ever brought inside for cosmetics purposes and easier connection), or move it to another location such as a bedroom or the opposite bathroom corner.

Sorry, but not sure what you are expecting anyone to say, there isn't a magical solution.

Thanks Plumbob,

Is there any reason why it should not have 90 degree bends in it? If not then i'll probably move it to the other side of the bathroom and then rejoin the exiting route once it enters into the loft space. That will mean 4 90 degree bends in total.

The reason for the vent is to prevent a pressure difference occurring which will suck water out of any traps. You can fit as many bends as you like, and the air will still flow to equalize the difference.

Good luck

Great news!

Many thanks for your help.
