soil stack

Hi all, will be getting a plumber to do the work but have had differing opinions and want to crack on with the other work required which means I need to raise the floor to the correct level. I live in a second floor flat, there's one flat above me. I'm adding a small en-suite wetroom but the...

Hi all. I am installing a new toilet downstairs next to an outside wall. There is a 3 way inspection/access chamber about 1.5 metres outside this point which I plan on going into. It has one inlet in use from the upstairs WC and the other capped off. I plan on going from the toilet out the...

I have Floplast waste pipe and need to feed into the soilstack. Due to space restrictions (internal wall built over the top!) it will be easier to use an offset reducer, but Floplast only manufacture (solvent weld) reducers with the entry point in the centre. Obviously other manufacturers do...

Our internal soil stacks are attached to external vents on our roof and the felt has not been sealed around the pipes. The wind howls through the attic space as there’s plenty of ventilation at the soffits and along the ridge line. See attached photos. Is this a standard / best practice type of...

Hi all, We’d like a toilet downstairs, but there are some isues. Our drains are at the back and feed into the main sewer at the back of our garden, so the existing soil stack (and the new pipe) MUST be at the back (WC goes under the stairs). Unfortunately, our foundation is solid concrete all...

Hi I'm hoping someone could advise me on what to consider in my case as I'm clueless about such things. We are looking to get a downstairs toilet. The drain is at the back of the house and the stack pipe is internal and is in the middle of the house. We had a professional come out and they said...

Hi, We recently had an issue with slug marks on our kitchen wall and, while investigating where the slugs might be getting in, I took a look inside a hatch in our kitchen which allows access to our soil stack and stop tap. While I was looking, I noticed a small amount of moist soil around the...

First time poster with limited plumbing experience - go easy on me :) We're doing a loft extension, and will have an internal soil stack serving a ground floor, first floor, and loft toilet - the 3 toilets are pretty well aligned. The soil stack will be 'boxed in' on the ground floor and first...

My house was ment to have a wc downstairs im looking to install a toilet and sink, as far as im aware the soil stack has been bunged with rags and skimmed over, will I have to replace the soil stack compleatly of is there a connector i can connect to the original soil pip to do this, all the...

Hi, I have a victorian property that I purchased earlier this year. We're just in the process of digging a French drain around the property and as we removed the top layer of patio slabs next to the soil stack vent, I noticed that the pipe in the ground was not connected to the pipe running up...

Hi, I'm doing my soil stack, but having to attach it 13cm away from the house to leave space for external wall insulation which I'm having done in a few months. I thought I was doing well! For the two runs of 40mm waste, I intended to use two 135° bends to get the 40mm pipe closer to the wall...

Hi, I'm getting external wall insulation done in a couple of months, but need to temporarily attach my new soil pipes/stack, but leaving a 13cm gap for the insulation. My plan was to dig up the underground horizontal, pipe see if it's in ok condition, then cut a bit off or replace it with a...

Hi all, I have a three-level, end of terrace house. It has an internal soil stack (black PVC), and it can be noisy. When people on higher levels flush, it is very audible in the sitting room. The stack doesn't pass through the sitting room. It passes through a small groundfloor WC surrounded by...

Hi, I took off my very old soil stack with the intention of getting external wall insulation done. The company could do it in a few weeks which would be fine, but I just heard the news about grants in September for these kinds of jobs, and I'm on borrowed money so I feel it would be best to wait...

I can only find 92.5 degree 110mm elbows, and while this makes sense to get a fall, what about when the elbow is used horizontally to go from a horizontal 110 pipe into the house to connect to the toilet? Surely then I just want a 90 degree elbow? If anything the extra 2 degrees will point it...

Hi, I'm looking to re do all the waste pipes on the back of my house as I'm fitting new toilets etc. I've never done this before, so just wanted to make sure I'm on the right track. If you see the current photo I plan to basically replicate this, but go more directly to the toilet waste...

I'm a reasonably competent DIYer. Pic shows current configuration of toilet in downstairs cloakroom. We are planning a refit with all new fittings, decor, etc. Obvs, but soil stack is in right hand corner. I'm going to box-in new cistern to hide soil pipe from loo and install a back-to-wall...

Hi all, We live in the middle floor of a three story block of flats. In our bathroom behind the toilet we have a panel where the soil pipe runs and all our waste pipes run to. We have always had a musty smell that we could smell every now and then in the bathroom but wasn’t ever that bad...

Hi, I've been reading this forum for a while, but I'm only now braving my first post. I was hoping someone may be able to advise? I'm building an ensuite in my master bedroom which warrants a new soil stack on the side of my house - the existing stack is on the other side of the house and...

Hi, I have an 8 foot section of a cast iron stack that is failing and is from ground to plastic above. It was originally external but is now internal to a garage (and tucked in to the corner). It just serves the upstairs bathroom and all inlets are in the higher level plastic pipe. The CI...
