air activation valve install

[angellonewolf]

i have in my house a soil vent pipe that vent straight out the roof i am redoing the bathroom at the moment and want to ideally remove the top part of the vent and install a air admittance valve about half way up the wall above the highest u bend in the sink

we have 7 or 8 houses on my side of the street and this is the only soil vent pipe in my house to the outside.All of the other houses are using the same normal soil vent pipe from reading up on it ? you only need 1 in 5 or 1 in 7 to have a vent to the outside in a run ?

but what do i need to know before if i can install it

thanks for any help angel

ps can post a pic if it helps later ?

yep you can possibly remove it, but when you get issues later on with blocked drains what you going to do then. In gthe perfect world your house builder did the right thing and your property had its own vent pipe, because your builder knew a thing or two. Houses that share vent pipes inevitably get blocked drains

Yeah durgo valves are ok but some times the flap inside can stick open ( letting smells out), make sure you can always get to it. it should be above the highest overflow point, that'll be the basin overflow.

I am no expert on this but the old memory banks tell me no dont do it, because your open vent is there to vent your side of the street. I am sure somebody will be along soon to say I am talking bolloc*s as usual

Just re-read what you wrote, what do you mean by yours vents outside and the rest are using 'the normal vent pipe,.?

It must be above the highest spill over point . So 25mm above the highest sink rim or toilet pan connected to it.

Take vent pipe out through wall and up outside of house, no need for a dirgo and no blocked drains.

if indeed yours is the only vent on the street then no you cant fit one, 5 houses to 10 need a vent to outside furthest from the main drain and 10 or more need vents in the middle of the run aswell.

i hate durgos with a vengeance we had near perfect drains 60 years ago and the model hyas been changed over the years for thesole reason of cost and making house building more profitable
drains never used to smell unless they were blocked now they stink all the time

thanks for all the replys sorry was at work and could not reply

here is a few pics to help hopefully

one pic is a hand written pic to show diagram of street and relation to my house the dark line is the sewer and pipes to each house

the other pic is a pic of the bathroom

i cant move the pipe outside as there is a garage in the way so any movement would have to be inside of the house or a air vent if poss but i dont like the idea of a blocking regularly if that what it will cause

ps i am very good at diy and have unblocked drains and moving pipes so any of that should not be a problem

i mean all of the houses on my side of the street are built the same as mine all have a soil vent pipe built in to the bathroom and then out of the roof


thanks angel

This seems alot of effort and expense for no gain at all and possible future problems.

If you need to fill your weekend you could try golf or gardening perhaps.

if i go down the way of leaving the pipe as it is a bit later on in the year i will be installing a on suite on the main bedroom and will have to pull apart the soil pipe to add in another hole a bit lower down and run a pipe across the ceiling to the middle of the house how do you pull the pipe apart with out desturbing the vent bit on the roof or if i have to pull apart will i need to get on the roof and remove the vent part first ?

thanks for the help angel
