I've bought a flexible pipe, but it doesn't look very substantial, and I've had what may be a better idea. There is a push-in rubber seal between the lavatory outlet pipe and the soil pipe. If I remove this there will be a gap of about 10mm all round, can I fill this with some solid cement type substance - I think I've seen this in the past.
Would Plumbers Mait, or some sort of plumbers putty or mastic do it? ChrisOfBristolDec 10, Get a new pan connector and do the job properly and hygenically. G BrownDec 10, Plenty of proper connectors made to do the job. Buy one of the right size and length and it wll be fine. Do not bodge it. Captain LeakyDec 10, I wasn't aiming to bodge it - I thought there might be something that sets hard, is there such a thing?
I've had a good look at the various connnectors but couldn't see anything that would fit in the space. What do you think of those flexible conectors? No need to mess about with sealants. Just fit the right size WC connector - it will do the job properly. Flexi connectors are OK so long as they are used properly. I probably didn't make it clear that it's not just the join that's flexible, it's the whole pipe, it's corrugated like a vacuum cleaner pipe.
It doesn't look very thick and I would have thought that the corrugations would be bad for liquid flow. There is some cross purposes here - The flexible pipe you mention is part of the connecter between pan and soil pipe boss- it is usually only necessry to use these for substantially offset pan spigot and the soil pipe boss.
There are many types which don't have a flexible part to the coupling which should cover most situations of offset and distance from spigot to boss. The rubber sealing flutes on the fitting will allow a seal to be maintained with the normal structural movement present in a house.
The confusion here is the actual seal into the soil pipe which should not be rigid but will be flexible through the aforesaid flutes.
Soil pipe leaking - how to fix?
Grabbit while you can It's Gone, but was it any good? I won! Coronavirus: The latest from MSE The MSE team is working extremely hard to keep the info we have about your travel rights, cancellation rights, sick pay and more up to date. Hi, We have a problem with our soil pipe the large black one that takes waste from toilet. Before we owned the house it had what I think is called a "boss" pipe added to it - an extra small pipe routed into the side to take waste from the bathroom sink as well.
The sink waste was then re-routed somewhere else and the boss pipe was removed but leaving in place the "boss" bit sealed off. This "boss" bit keeps leaking and we can see pee yuk on the paving stone beneath from time to time. It is only drips and nothing worse than this!
We can't even work out clearly where the drip is coming from but it is somewhere around this boss. Have tried putting loads of silicone sealant all around the area but this hasn't worked. Please does anyone know what we could do to seal the leak?
Would prefer not to have to remove the whole pipe as it is cemented into the ground and it would be a nightmare to have to lift the paving stones etc.
Is there a way to cut off the section of pipe with the boss bits in and replace that part and if so how can we ensure the new bit doesn't leak?

Hello, I had a blocked drain recently and it caused my downstairs WC to flood when the loo was flushed as the soil pipe has not been sealed and waste water backing up in the drain came back up around the pipe which is boxed in behind the loo.
Not my shoddy work I add! Can someone advise me as to how I should seal the gap around the soil pipe to prevent this happening if the drain blocks again please, my concern is that if I use cement or an expanding foam type product some will fall into the drain and may contribute to the likelihood of future blockages.
Is there some kind of collar I can fix around the pipe and seal? Thanks in advance It's not normal practice to add sealant at the joint of soil pipe and a fitting, so I would think twice about doing that, and then not do it. Can you take and post a photo of the troublesome joint, so that better advice can be given? Softus18 Jan It's the hole where the soil pipe disappears through the floor, there is a gap of around 10mm between the pipe and the edge of the hole in the ground Ok, I have uploaded a picture hope this makes things clearer?
The problem is the gap between the soil pipe and the hole in the floor leading to the sewer OK I can see the photo:. Best picture I can manage but will try for anotheryes, the picture is of the pipe going into the floor yes that is the concrete floor you can see.
Seco, that sounds possible, I have posted another picture Actually the missus says it often smells in there but she just thought it was me! Thanks for your help Seco, will fit a sealing ring Joined: 3 Sep Country:.

Replies: 4 Views: Hey guys, need to tap the hive mind for advice on some home repairs. BTW, this isn't really a H ouse but instead a townhouse apartment that we're talking about here with a long history of craptaculous half-assed repairs being done, hence the reason why I'm going to try and do this repair myself.
I think of it as a good way to get some experience in for our first home. It appears the pipe was sealed with some sort of caulking which is decaying. I swear it looks as if it's just standard white silicone caulking that they used. That would explain why it seems to be coming loose from the pipe. It wouldn't surprise me in the least if it was. What chemical goodies should I be looking for? PVC sealant, glue, expoxy, or other? Are there any special considerations for sealing waste pipe PVC vs.
Thanks guys! I'm not expert on this subject but maybe its not supposed to be a glue or epoxy so you can get it apart if need be. I see plumbers putty at the store, maybe thats what its supposed to be sealed with. Be prepared to spew feces all over your basement first, then break the joint. Clean the area to be adhered with sand paper and the prep chemical they sell next to the PVC cement. Just reseal it. That will last for many years and if for some reason you have to take it apat in the future, just cut the pipe and put in a splice.
Happy schlepping. I'm just not clear on what type though since there's a bunch of different types to choose from. Some of them may be fine for normal drainage like in a landscaping situation but might not be suitable for your house's main sewage drain.
Anyone here that can loan me a clue?? Don't quote me on this though- ask at the dee pot. Thanks for the not so good news Carhole. That's what I needed to know though.
How to Seal Pipe Holes in a Brick Wall
You're certain that the existing joint can't be sealed in some way? No cracks or such, just a small leak at the joint above the tap.
If you mean it is leaking around the plug that is screwed into the pipe, this must be free, so it can be removed and the drain cleaned out. If it is leaking around the area that has the plug, yes, it must be sealed.Discussion in ' Builders' Talk ' started by diyhopefulOct 6, Log in or Sign up. Screwfix Community Forum. Water seeping in around soil pipe. We have a soil pipe that comes down the outside of the house and then enters a small, tiled, pitched roof.
The rubber diaphragm type seal also has some aluminium foil sticking it to the soil pipe but this is coming away allowing rain to run down the outside of the pipe and drip off a bend inside the ceiling void.
Is there something other than the foil tape I can seal the pipe to diaphragm or even replace the diaphragm with?SOIL PIPE STRAP BOSS - HOW TO DRILL AND INSTALL
I'd prefer not to remove the soil pipe to insert a whole new diaphragm. Hope this makes sense and any advice would be appreciated. You can get a collar that fits around the soil pipe to throw the water away from the seal - if that makes any sense!
Any ideas where? Screwfix don't seem to stock anything like that. And fix in place with a good quality exterior silicone sealant. IF the soil pipe is also PVC and a tight fit - fair enough. I'll have to take a look up the ladder at the weekend.
Was hoping to "fix" it without having to remove the soil pipe though. Ah, does the pipe have a fitting at the end which would prevent this collar sliding on? A few dollops of sili to stop the panel flapping about I think the builder that installed it used a vented slate like the one you show DA but then cut the hole a bit too big and wrapped alu tape round it Bloomin' builders etc,etc But the tape did last a few years I feel a bodge coming on.
Thanks again guys.If you have noticed a bad smell coming from your toilet or bathroom and it comes and goes… more than likely its a leaking toilet waste pipe rubber or pan connector rubber known in the trade. Some times when the waste pipe rubber is worn and which is often called toilet pan connector rubber it can leak water when the toilet is flushed and the gases from the main sewer line which is methane back into the room.
Below I will explain on how to test and replace these toilet pan connectors on both a P trap and S trap toilet. With a P Trap toilet which is the type that goes through the wall will show up more of a leak from a perished pan connector seal than an S Trap.
P Trap toilet pan test- Make sure that the toilet tank is full for this test. Look and feel with your hand for any water escaping from around the seal or if you have any food color die can help to. As above can add some food color die to help see if there are any leaks but as said above the S Trap is harder to pick up any leaks.
You are relying more on a visual look at the rubber seal to see if any water is leaking out but more to see if the rubber seal is perished and letting methane gases escape back into the room. Now that we know the difference between a p trap and s trap toilet pan and how to test to see or know if we have a leaking toilet waste pipe. Below is a step by step procedure on how I do this job and how you should do it and what not to do as well.
To replace the pan connector rubber seal you will need to remove the toilet pan from its location. This can be a job in its self as toilets are either screwed and silicon down to the floor or concreted down.
If concreted down then you will have to replace the pan as there non-reusable once they have been concreted down. These steps are for low, mid and high-level toilets and may vary depending on which toilet suite you have but the principle will all be the same. Turn the water off at the toilet stop valve to stop water going to the toilet tank cistern. When off push the buttons down on the tank to drain the tank out from all the water.
Depending on the installer they can be star drive or flat drive screws and should be either brass or stainless. Some installers only silicon down the pans and cut the heads off the screws and silicon them in where the holes are to look like there screwed down so if you are trying to remove a screw and keeps spinning that be what it is then. Install the new one and place the retainer ring back on.
That is as easy as it is to replace the toilet pan seal rubber. Toilets need to be fixed down on a flat and level floor if not it will crack or worse be on a lean.
Got a leaking pan cone rubber see how to change it today. Having a leaking toilet waste pipe really stinks pardon the punt. Get down next to where the toilet pan connector rubber is and push the button on the tank.Seal gaps around water, sewer and gas pipes that pass through brick walls to prevent conditioned air from escaping as well as unwanted pests from entering the home.
No matter how tight the fit, a gap will remain around pipes routed through brick walls. Several types of sealant are adequate when sealing these gaps, however; the type you choose should depend on the size of the gap. Dust the area around the pipe with an old paintbrush or handheld duster to remove dirt, dust and other debris. Load a caulk gun with exterior grade caulking. Prepare the hole by using a hammer and chisel to square the edges. Be careful not to damage the pipe.
Dust the area around the pipe with an old paintbrush or hand-held duster to remove dirt, dust and other debris. Slightly dampen the surface area around the pipe. Mix a small amount of cement in a clean bucket using a margin trowel. Apply the cement around the pipes perimeter using the margin trowel.
Work the material into the gap to fill additional voids behind the surface when necessary. Apply foam sealant to the gap around the pipe's perimeter. Either expanding or non-expanding foam sealant is sufficient for filling the gap.

Skip to main content. Home Guides Home Home Improvement Furnishings Seal your home by filling gaps around pipes that pass through exterior walls.
Use a damp rag to remove excess caulking. Don protective gloves, eye gear and a respirator. Tips Use a combination of foam sealant and cement stucco to fill large gaps and voids. Fill larger voids with the foam sealant, then apply the cement to provide a natural finish to the surface surrounding the pipes.
Warnings Foam sealant fumes can be harmful, and the material is extremely hard to remove from your hands, so be sure to wear safety gear. Follow instructions and warnings provided by the manufacturer when using foam sealant. Foam sealant is extremely flammable; do not use the material near open flames.
