soil pipe

Hi everyone! I am moving a toilet across a room. I have had conflicting opinions from two plumbers about soil pipe routing. I upload a dodgy sketch to explain. In the circle is the current toilet and vent pipes which are boxed. I need to remove the toilet and all the pipes in that wall. For the...

Toilet is leaking from this pipe and I’m not really sure how to fix it. Before going to a plumber I thought I’d come here to get any tips on how to fix it. Someone came to put a floor in and he moved the toilet when doing this. But since then the toilet started leaking.

An unsavoury topic, perhaps, and I apologise in advance to anyone who may have eaten recently! Our downstairs toilet seems to suddenly have started blocking very frequently. I've bought a toilet plunger, which never fails to shift the "material", and it'll be fine for a few days, then blocks...

Hi all, I'm trying to fit a PVC S-bend leading to a vent to an existing caste iron soil pipe. I've bought a converter, which you just plug into the hole of the existing caste iron pipe but found the rubber fins on the converter are quite shallow and it doesn't seem long enough to be secure. The...

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, We've got an old larder space that we're thinking of converting to a downstairs toilet and sink. Trouble is it's in the middle of the house with no soil pipe nearby. We were initially thinking of putting in a Saniflo (or a Wasterflo WC2 rather). But anyone you talk to seems to say to avoid...

Hi Our soil pipe stack is leaking from a pipe joint where it enters the flat roof of our extension. I noticed a tiny pool of water on the dry roof when looking out the window today. Photos show pipe joint and leak. Upstairs taps, bath, sink and shower all drain properly but upstairs loo often...

Hi, the horizontal length of 4” pipe from cistern frame to the face of the 92.5 degree bend which goes into the main stack pipe, is 1400mm and has a fall of 45mm i.e 1:31.6, is this okay? I’m aware 1:40 is the standard. See attached for more details. Also the joint of the bend and the 4inch...

I currently having an issue with rats in my loft space. I believe they are coming though my soil pipe and climbing that until they are on the roof guttering. I can stop that partially by blocking the soil pipe with a rat stop product. However, I also have a downspout that goes from the roof into...

Hello, I previously thought I had a problem with leaking ventilation ducting from an extractor fan vent in the loft caused by steam from the shower fan and/or a leak in the roof. This originally started as a nail had pierced the flexible ducting used to connect the 2 pipes in the loft and...

I’ve recently fitted a concealed grohe cistern (this one https://www.grohe.co.uk/en_gb/rapid-sl-3-in-1-set-for-wc-0-82-m-installation-height-38773000.html) and am now fitting the wall hung pan (...

Hi there, let me just start by saying I am no plumber or expert and am looking for some advice on doing my first 'big' DIY project of turning a small bedroom into a bathroom, specifically with the toilet. I want to put the toilet below the window on an external wall which is upstairs 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...

I am working on a project where a (proposed) internal Soil stack clashes with a partition. It is being proposed that the stack is vertically offset from the vertical by ~5 degrees (300mm over 3.3m). I am struggling to find anywhere within CIBSE / BS that mention offsets from the vertical. Does...

Hi All, We are going through a cellar to basement project and just want to ask a few details about the drainage layout and what offers both building regulation coverage, but also what is the most practical solution. We aren't 100% tied to the layout so if a more suitable layout would be...

The original cracked/leaking clay drainage of the house has been disconnected and partially removed, with an inspection chamber installed as described in this thread (thank you to those who so kindly offered advise) We have temporary drainage set up & need to figure out the next step. This is...

The soil pipes from our two toilets are ascending for a short distance - just under 400mm to the external wall. This seems a bit odd to me, but I am not in the building trade so don't know much about plumbing. The toilets work, but the do seem to block quite often. I am not sure if it is because...

Afternoon All, I have a detached garage which I wish to have a waste pipe installed in for a dog grooming bath. The new build house has an internal soil stack in the corner closest to the garage. Plan is to dig up the garden alongside the garage and run a 6m long soil pipe just under the house...

Hi, I would very much appreciate you input on my project. Project: I am building a side extension which incorporates a new WC. My build will go over existing sewer pipes and manholes. Status: I have planning council permission and now I wish to obtain Thames Water Build Over permission...

Can i use a 45 degree bend in the middle of a soil pipe run. I have to install a new inspection chamber, cannot get it square on to the existing chamber due to falls etc so would need a 45 about 2 meters from each chamber. Is this acceptable to building regulations and is it sensible. I know...
