Spend the money on a cu change

That RCBO is a bit random TBH. Was wondering what the merit was of fitting that. ?

@pocster Go buy a new CU and have it all tidy from the head in. That 100ma RCD is only worth scrap weight anyway as it offers no non-lethal protection. If your spending money, make it good money after good, plus it'll fly all the next checkups for years to come. There are already 10mm2 PVC earth cables to the gas meter and water stopcock so another job that doesn't need doing / paying for.

Yes...."we".

No. we should be collecting every scrap bit of PB we can and burying it in our houses to retain heat and stabilise our heating systems.

Lol. No. There can be only one........... PS are we buggering up yet another perfectly good thread ?

That's EXACTLY what I was just going to say

Hi and welcome. . Dont be shy of asking daft questions ( as I can then read the answers stealthily and look more cleverererer ). Naughty boy @jack. Gold dust like that needs to be ON the forum ( never know if I may need some of that juicy information ).

You and me both mate. If I could turn my conscience off I'd make a bloody fortune. Point being this is, all but one RCBO, front of house rcd anyway. There is no need to split or segregate and this is the guy who has a £1 meter on his missus's hairdryer so cost effective too. I'd recommend a CU change here to a modern dual RCD 17th ed board, of course, and if I was spending a few hundred THATS where I'd put my money. Safer, and 50% redundancy. You can buy a CU for less than these aforementioned bits will cost to retro fit into the existing CU so I'd go that way in a heartbeat.

There's big difference between immediately dangerous and not to current standards. This guys hoping to get an easy job. Would it not be cheaper and quicker just to ditch the single RCBO back to an MCB and fit a 30ma front-of-house RCD ? Change of £100 and less than an hours work.

I would NEVER say that Hush dave, you'll get me in trouble.

According to @JSHarris's comments, PB actually has good thermal absorption and retention qualities ( worded badly by me but you get the drift ) so once the shock and horror of the suggestion wears off it may not be so bad at all. It would definitely make acoustics better, for sound deadening, and if you bonded it with foam where it was needed you'd be able to use double depth plasterboard fixings to hang heavy equipment. Just the suggestion seemed a bit 'cowboy' to me at the time, so I didn't do it.

That's pretty good going tbh, and some complex angles to meet. Less than one sheet of waste makes you a hero . I was quite taken aback when a QS once told me to reduce the PB waste removal by filling up some of the stud spaces, with the offcuts and the 50mm of rock wool sharing the same 100mm void with each other . Costs a fortune to get rid of these days too.

After building a house, that's most folk isn't it ?!? ??

Like the Impey then ? Happy days

You can get a plunger on it at plunge it clean. Tbh with the first trap that lifts out and the 50mm waste, there's not much that's going to ever go wrong. These are designed to be where they are so I'd not panic about that. The Impey linear I recently fitted had a 3 section trap; hair trap, airbreak insert and the waste / body itself. With the top two removed you can stare into the 40mm throat. excellent bit of kit.

Can't you just use more strong boys if loading is the issue ? Needles are a heck of a lot of disruption ?

If I've grabbed the wrong end of the stick I'll apologise and put it with all the other sticks .

It'll be the orange propane iirc. TBH your gas fitter needs to advise you properly. I take it your not doing this yourself? Gas + hero = bigbaddaboom .

Thats the locate button too. Very handy in a large or 3 storey house. If the smoke alarms go off you press locate and it silences all the alarms except the one that's been triggered, so you can head there immediately to investigate.

The resistance of the water flowing through the UFH loops vs the cold mains would leave positive pressure in the hose, ( unless it's a ridiculously low pressure supply ). Plus the pipe would need to be constrained at the point of the pinhole. Likelihood of Venturi type suction occurring along the hosepipe? Imo, zilch. The ufh pump / manifold rarely gives a flow rate of more than 5 litres per minute through each circuit so it's vital to use the cold mains purge first to ensure that no pockets of air remain. The loop can airlock with ease when you revert back to the pump only if it's not 'blasted' through. Ive serviced a few where one zone has air-locked and the others are working. Sometimes you can get them going again if you turn every other actuator off but some I've had to purge through again, usually in installs where the pipes rise slightly as they move away from the manifold.

What did it say !!!!!

Now your just showing off. I still chuckle when I read the title of this thread .
