Managed to get a small hole in the kitchen sink (see photo), which is leaking underneath. Unfortunately the sink can't be easily replaced as it's fully integrated within a granite worktop. Just wondering what's the best way to repair this? Would applying plumbers mait underneath the hole keep...

I think there was an O ring in the soil vent pipe but for some reason it didn't fit securely as the other connections. I'll tape it up and monitor over the coming months. I possibly could have used another adjustable bend but it probably would have involved a lot of fiddling about in the...

That's me fitted it now (see photo). Everything connected well except for the final cut pipe end (attached to the flexipipe) connected into the soil vent pipe. This fits in and fills the soil vent pipe hole well enough but it's less secure than all the other connections. You could easily pull...

I think I've come up with a solution if I cut 2 small (10cm in length each) narrow (110mm) sections from that 1m pipe. If I file these at each of the cut ends it gives me some narrow connectors to join everything together: - connect 90 degree bend pipe directly into existing roof vent pipe -...

I'm trying to give the non-AAV option a good try before potentially resigning myself to the AAV. To do this I was going to connect a 1m pipe to an adjustable bend pipe ( https://www.screwfix.com/p/floplast-sp560-0-90-adjustable-bend-grey/50087) to connect to the existing roof vent pipe. This...

Thanks Hugh that really helps me better understand how AAVs work. Thanks for all your help

Not at all, just want to go with the simplest solution where possible. I've already completely sealed off the soil vent for the past 2 weeks until I figure out what to do. The only noticeable impact in the house is some drain gurgling. So I'm thinking worst case if I did fit an AAV I might at...

The soil pipe (going all the way to the ground) is vertical. I was struggling to adjust the bends to a suitable angle and didn't want to spend too much time up there faffing about with pipes, bends, coupling etc as its a nightmare for my asthma (even with a mask on). It's a really awkward space...

Thanks for sending that on Hugh. I tried to read it on my phone which probably isn't the best idea as there is a lot of info in it. Ian - just print off the pdf from the link and save paying £14 on ebay. Hugh - it's hard to fit everything into 1 photo so I've posted this short video. Ignore...

Some interesting suggestions although I didn't even think about aluminium ducting for a soil vent. I just assumed it wouldn't be suitable and durable for this purpose. Hugh - that flexi pipe is only 480mm. My gap is around 1.4-1.5m. I've struggled to find anything advertised as suitable for...

The solution I described above won't work based on the vertical height and angles between the top of the soil vent pipe and the bottom of the roof vent pipe. It just won't fit. The only solution is either to fit an air admittance valve on top of the soil vent pipe with no connection to the...

Thanks for the tip. Never done anything like this before so any tips welcome! Can I just use washing up liquid to lubricate between the pipe and adjustable bends? Or do I need a special lubricant? How far would you normally need to insert a pipe into these fittings? I'm thinking in terms of...

Thanks for the reply. I had another look and I'm sure the extractor fan is actually separate from the soil vent pipe. I take your point about the potential drawback of option 2, fitting an air admittance valve. That it would restrict the drains being able to fully breath. I had a look at...

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...

Thanks SFK that's reassuring to know. Cheers Scott

Just a follow up question with this... So I replaced the bathroom extractor vent cowl with the mushroom one from toolstation (see attached pic). At the same time I decided to replace the soil vent with the same type of cowl. I was just wondering if it is actually a good idea to replace the...

I had a plumber check this out when he was doing some other work and he reassured me that it was nothing to worry about and easy enough to clean off. Thanks for people's replies.

Thanks for everyone's thoughts. It sounds like I've got nothing to worry about which is a relief

How long would you normally wait for a retreatment? I don't think the posts are in concrete. Would you normally expect them to be?

Just had a new fence installed with some strange blue stains. Any ideas what these might be and if they are a concern and possibly need fixed or treated? We're being charged £650 in total (labour and materials) for this double sided fence. Just wondering if this is a fair price? Any advice...
