ok guys , ive got a temporary bathroom set up while my permanent bathroom gets sorted , the problem ive got is where to drain my bath to. there is a loo in the room next to the temp bathroom and just outside is the drain from the loo that runs to the sewer. from this drain runs a vent that goes up the said of the house , i can patch into this pipe.
can i drill a hole into this drain pipe and run my bath drain into it temporarily? would a core drill go through it? its a clay type pipe.
the only thing i am worried about is causing a collapse in the drain through drilling into it. the bath drain will be 40mm so i will need to drill a 40mm hole in the foul drain pipe.
the pipe up the side of the house is asbestos , i dont want to drill into that. its the pipe underground that connects it to the loo that i want to connect to.
Vitrified clay takes some drilling into Bert, just as easy to install a junction if its 100mm pipe work.
Can you drill through the dividing wall and connect the sink to the pan connector at the back of the WC ?, you would have to add a temporary AAV as well.
its the bath i need to drain. the wc pan connector is below floor level as the pan trap terminates vertically and id rather not have to dig up the floor.
how about drilling into the asbestos vent pipe that goes up the side of the house? i know drilling into asbestos isnt ideal but the only other (easy) way i can see is running 40mm plastic waste pipe underground down to the inspection chamber and draining into that.
is the asbestos pipe going up the wall just a vent or does it have connections in it. you could a specialist contractor to remove and dispose of the pipe then replace with a short length of plastic and an air admittance valve.
failing that is the asbestos in sections can you just remove one and replace, saves the associated risk to you and those around of drilling it.
its just a vent for the toilet , no other drains connected to it. its one big length , i am not sure how deep it goes but its not too deep. its connected to clay pipe underground.
this drain will all be redundant soon when we get the new drain in for the bathroom on the other side of the house (see my other thread) which currently drains into the rain water drain.
i dont mind drilling the asbestos , providing its done properly it should be safe enough but obviously if i can avoid it i will.
one of my alternatives is to take the 40mm plastic bath waste out through the wall then down below ground level and terminating in an inspection chamber about 4 meters away , its a bit of a pain because there is a concrete path in the way but i never really liked the path anyway and was going to take it up sooner or later. with there being an open vent connected to this chamber i shouldnt have any issues with the trap below the bath being breeched should i?
this only has to work for a few weeks until i get my bathroom plastered , plumbed and fitted out.
If, as you say: it's temporary works. Why not run it above ground and into the top of your manhole? Take off the lid, replace with double thickness ply and cut a hole the size of your outlet pipe.Fix ply in place by drilling holes and screwing down sealing with mastic. A lot quicker and cheaper, will save you cutting into asbestos pipe, or a dig down.
leave the asbestos alone and run temporary to manhole direct. cheapest and quickest option, and easily reinstated later. adavise get asbestos removed and replaced with contemporary material later
