Apparently, he can burp the alphabet....... I tried to book him for my daughters 13th, but his mum said he wasn't allowed out.

Yup. The mains peaks out at around 04:00 and the use of a non return valve captures the available potential, usually north of 2.5bar sometimes as high as 4bar and that’s sat there ready to utilise for the days needs. What matters, is how much of it you stored.

Accumulator vessel is undersized. A pre-charge of 1.5bar vs 6bar cutoff will see the diaphragm being exercised a heck of a lot further than I would ever specify in a design for any of my clients installations tbh. The upshot of this is a lot more % of stored pressurised water vs redundant air space in the accumulator, but it will massively shorten the lifespan of the diagram ( aka bladder ) too. I never fit less than 300L in a family home with a poor cold mains, and set it to accept 50-60% water ( max ) to give the vessel / bladder as long a life as possible. The reason you run out of water so quickly and the pump starts up again under duress is down to incorrect specification alone. I would add at least another 1x accumulator of Dili mar or slightly bigger size to improve things. The pump also has a limited lifespan and this cycling will ultimately see that needing changing sooner too. FWiW I have never fitted a charge pump to a mains, even ones where I can p**s quicker than the water mains, instead just fitting much bigger acc’s and leaving them to be pressurised off the static head of the cold mains instead. Works extremely well. In my experience of over 2 decades of installing these devices on multi-occupant dwellings with poor to very poor cold mains, I have not once fitted a pump to the cold mains, instead it’s just been down to specifying the correct size acc’s and the results have been excellent.

One for your structural engineer

Completely agree. We threatened you from afar to get rid of the piss-coloured grout, and nothing. But then when we came around mob-handed to show you we were serious….bingo! Glad this shambles got stopped now before it got any further. Time to say “Adios” to Roy and Woody. God help their next victims……

I've bought 2 sets, maybe I will buy another two. The cheapest I could find a 4-pack of 5.0's was £260-£270, so for £300 I couldn't say no. I now have 2x drills, 2x chargers, and 2 x cases up for grabs if anyone wants them? I'll put them up on Market Place here over the weekend, or PM me with an offer anybody I already have the heavy duty brushless drills / impacts, plus an identical brushed drill as a backup, so these are completely superfluous to my requirements and need new homes. The warranty can be claimed by the new owners for 3 years trouble free motoring. I will register the batteries only in my name.

@Wilko58 Sorry to be asking this a bit late on, but have you proved the 110mm AAV is functioning properly / at all? Does the 50mm tee in under the 1st floor boards, or does it tee in at ground floor level?

That’s what I suggested, as they cannot be boxed in. They need accessibility.

Another for Brink here. I fit nothing but Brink ( via CVC Direct ) and always excellent results from both the units and CVC’s client / consumer support. ??

A typo one lol.

Ideally the AAV should be above the trap height of the basin. Can you extend that 50mm pipe up alongside the SVP and terminate in the attic?

?‍? Ermmmm……..

Just making sure you don’t fry the ones you love the most…….Zippy, Bungle and George. ?

It will be, by the fact that the incoming live goes to the terminal C ( common ) and the switch wires to L1 / L2 etc. Now, more importantly, let’s have that chat about colourblind people DIY’ing their own electrical work……… ? lol. My dads engineer was too, and had to keep coming back and forth the office with short off cuts from the vending machine wiring looms asking which colours were which

Yup.

That explains the grout then !

They’re both live cables ya nugget

They’d likely just fail it possibly with a recommendation to come back less the offending item(s), which would be free as you get 2 ‘hits’, iirc, before having to pay to submit again. If the amendments are not non-material and you have to come back with a full resubmission then you may have to pay the fees again. Panicking too soon isn’t healthy, just wait and see what they come back with.

I assume this is a typical ‘boat’ hot water system, but if there is no vent then I wonder how expansion / contraction, when the water heats up and cools down, is overcome? What temperature does the water get to?

Don’t fit usb sockets though, as that can cause issues when doing insulation resistance and other ‘dry’ tests

Ask your sparky first. A lot will get the hump, quite rightly so as well, if you start cutting and stripping their cables without prior ‘permission’. They are damn well entitled too!! Insurance, competent scheme costs, all the gear to keep and update / recalibrate, running a van, paying your taxes, vehicle costs and more. Why would they not charge you when it’s you that asks them to come to do work ?

One of these LINK directly onto the top, PTFE’d on, and then take the flexible grey ( poly or Hep2o by the looks ) further away, or possibly replace the garden hose completely?!?

Are these under warranty?

Fractional. Some, yes, but I would say bumping up ton15mm PB would would exceed that value, and keys not forget about a skim coat which also has inherent heat capacity also.
