What about the actual branch connector, there is usually a boss on the side of those. Photo?

Is there not a branch where the vertical grey pipe and the sloping brown pipe from the WC meet that you can connect into below the floor further to the left?

But a 100 square metre building will need some heating, unless you never plan to use it in the winter. So why not use the heat pump you have? What else are you going to use?

Post an anonymised satellite view to aid the discussion?

Hi and welcome. You took a long time to find us, we have been going many years now.

The fuse, which by it's nature is a bit of resistance wire, will also have got hot and looks to be the culprit. Feed it directly from a 20A double pole switch, not a fused switch unit or you will just be moving the next failure to the FCU.

Surely though if installing mvhr to a non airtight house, you would at least block up all the old original individual vents for the multitude of individual fans, and block up or keep closed the window trickle vents, so you are down to just the leaks in the building fabric rather than all the previous deliberately made great big holes in the building. And while you are at it block up the letter box and cat flap.

Same as with a tiled roof. Counter battens then battens over the membrane and fix your wriggly tin sheets to the battens.

Done

But I would not change the agreed layout without first discussing it with the customer.

I selected Johnstones, that's what we use for final coats. BUT on a new build I thoroughly recommend Wickes trade matt white emulsion for the first coats on bare plaster. P.S do you want me to edit "Paint Pole" to "Paint poll" ?

You have to show him the drawing, and get him to explain why it is not according to the drawing.

Keep us posted.

I have done a few and recon 2 days for me the electrician and 2 days for the plumber so 4 man days. I might come out of retirement for £2000 per day.

Meter box designs are lousy to start with, you only have to walk round any housing estate to see how many are secured in place by duck tape. Fix some proper hinges and ignore the silly pins and it will be better that it ever was. I would nut and bolt them on with big washers to spread the load, I fear pop rivets may pull through the thin fibreglass.

Another self builder further down our road had the road crossing for services made by an unregistered builder, i.e did not have any form of street works permit. He made a far far better job than Scottish Water who did mine and did have the right permits. Just proves having a bit of paper proves nothing about actual competence.

All you can do now is wait and hope. If it does start moving now, you know why.

Confused. First picture is walls being built, without their facing stone? Last picture in post above is finished walls, with the stone front, and filled in and grass growing. So some time later? It's a bit late to ask if they are okay then?

Looks like it, less likely to be a cable fault. Could just, if you are licky be a connection inside the pump. Soak it in a bucket of water / bleach for 24 hours then have a go at opening it up?

Can you sketch a wiring diagram and I will give you some ohm readings to take Also post a picture of the pump.

Are you SURE it is registered with the Post Office. HOW did you register the address?

If the cap is located remotely, then both windings will be connected back to the control box. I would expect a 3 core cable in that case (but could be 4 core) With the mains disconnected, what is the ohm reading between the two pump wires connected directly from L to N? And what is the ohm reading from N to the pump wire that connects to the capacitor?

We kept ours as well, but our plot is big enough it is not intrusive and in any event there is access so it could be removed if I wanted to. I had a bit of a tussle with planning about it. They only wanted to grant temporary planning for the 'van with the clause it must be removed from site upon occupation of the house. I pointed out it's location would fall under permitted development as a garden outbuilding, so on completion day I could remove it, and then immediately replace it with an identical 'van in the identical position under permitted development. They agreed and changed the clause to residential use of the 'van shall cease upon occupation of the house. Ours is used as a storage and general work space now. We only paid £4K for it, lived in it for 18 months, and where else would you get a 30 square metre garden shed for that price?

Yes almost certainly the capacitor, the question is how easy is it to access. Is it a submirsible pump?

the heat pump will have a minimum flow rate below which it will throw an error. Fit a manifold circulating pump to be sure, or if you want to wing it, just try it, you might get lucky but if your HP throws a flow rate error be prepared to add another pump or 2 somewhere.
