Choice of Pex-Al and Pert-Al at Wunda

Not unusual. From memory the door sizes and garage sizes haven’t changed in decades, and most developers don’t expect you to put a car in the garage - it’s for bikes, junk etc ..! I think the standard size is based around a Ford Prefect or something similar ..??

PIR and PUR both absorb moisture and are not certified for permanent damp conditions.

Can you show how you get to that figure ..???

Polystyrene beads..?? It’s been discussed before !

Nice tool here that may help you make decisions http://www.floodmap.net/

Steam mops are always pretty good for this.

Looks like that manhole has seen better days .!!!

Yep - 50mm of EPS, then a DPM and 110mm of PIR and you will be fine. EPS is relatively cheap and will also stop any DPM getting punctured. PIR takes UFH staples much better than anything else.

Got a photo of the inside of the manhole ..?? I’d reckon there is a 150mm clay section in the bottom of it. The “proper” way isn’t going to work so I would do the following Get a clay to UPVC connector and cut it just after the UPVC sleeve. Slide this onto your UPVC (Easier with a short section - 7-800mm will do, preferably with a socket on) the “wrong way round” so the open wider clay end faces out of the manhole. Bevel the end of the UPVC to 45 degrees and slide the whole thing into the manhole so you have 150-200mm inside the manhole, but not past the next branch. Now force the rubber back inside the clay from the outside, making sure it goes in all the way round - long screwdriver is good for this ..!! Set your levels so this short section has a 1:40 or less into the manhole and then fill round the pipe and the first 3-400mm with a semi dry concrete mix ( use Rapid Set or even post mix here) Once this is set, bench the inside of the manhole - don’t use rapid on the inside, use a 3:1 sand cement mortar and make sure it’s all nice and smooth and tidy...

As @JSHarris said - pitch fibre. They delaminate and deform over time. Get them all out and replaced as they are a nightmare to get a decent connection on to, and invariably collapse as soon as you mess with them. That hasn’t been bedded properly either so it’s probably unstable now you’ve exposed it.

Make one ..?? Have you got a length of 125mm pipe..? Cut the pipe at 20 degrees, rotate it 180 degrees and glue them together - gives you your 40 degree elbow. If you then smear with CT1 and tape with decent foil tape it will be fine.

Yes you can over drill the core for a joint - you’ll need a 125mm core drill.

Can also use a Sonoff TH to do this - benefit is you can control via ITTT or the app. Here is the site

I’ve got rid of my rods and use one of these on the pressure washer. Drain Jet It will blast blast it’s way through the worst blockages and is also flexible enough when soaked in a bucket of hot water for 10 mins to go round a u bend ...

I’ve got an Argon bottle that I bought then I pay per fill. He certifies the bottles and then swaps it every 5 years or when it’s damaged.

Yep

Ties may not be in line with joints perfectly but a tap down with a trowel sorts this. Never knock up, at worst give them a twist and put them in the perp if you have to. Are you insulating the cavity ..?

Congratulations..!! Must mean the bathroom is finished ..???

No it’s the right way ..! Got the clips ..??

Yes - it’s called Newton’s Law of Thermodynamics .... Just to advise, until there is some solid technical and accredited research shown by @Clive Osborne regarding Nexgen then please can we leave this thread as is.

Its because it isn’t hot. Thermostatic valves need a temperature differential to operate - it’s locking down the flow because there is no hot water to open the wax cap.

Yes - specify Ultion locks now, and they have a £1000 excess guarantee on them too. Some clever bits inside, and keys are incredibly difficult to copy. Not cheap but worth it. https://www.ultion-lock.co.uk/

Yep - concrete commons are available.

Interesting as Aluforms director used to be the Ops Director of Velfac... I would push them hard to help you here ..! https://beta.companieshouse.gov.uk/officers/kCCZuqYUPmpgbqj_hbBUxX3OfI0/appointments
