But in summer when the bedroom window is open, it will not be heating the house will it? It will only be doing hot water heating, and use the timer so it does not do that while you are in bed. My take on the noise thing. My ASHP makes about the same level of noise as an oil boiler burner roaring away. But people are happy to put an oil boiler inside the house so the noise it makes is inside the house, but seem to have a problem putting that same level of noise outside, just in case they might open a window and hear it?

Are you aware of such an "internal" ASHP? And what are the "tubes" you refer to? Apart from exhaust air heat pumps, all air source heat pumps have an outdoor unit.

Well here the "main" that serves 12 houses is 50mm and WELL over 100m long, so i would say 50mm for one house is over size.

I wonder if an air blower treatment plant can only cope with a small amount of sludge before the blower outlet gets blocked and then the build up will be rapid?

We have an island in a similar space, and like it. BUT our kitchen is not a through route. I have seen a similar kitchen with doors in opposite corners and when just "passing through" it is an irritation to have to dogleg one side or other of the island, particularly if there are stools or other items in the way.

I would not fit them personally. the only place I used unswitched sockets is behind appliances and tv's etc where you don't want to go to the bother of installing the appliance to ten find out you forgot to turn it on but can no longer reach. Do they not do a switched version?

Not stock issues, but I ordered some plasterboard, P5 flooring and other timber and am now waiting over a week for a delivery slot on the builders merchants wagon.

Well I have been and checked. The air blower is blowing and you can see and hear the contents sloshing about agitated by the air bubbles, so all appears to be working correctly. It was just that it was over due a service.

This is for our old house, to cover the top of the pumping station. The neck is 600mm diameter but pushed a little out of round by the backfilling (but that could be corrected) When installed 18 years ago it was supplied with a standard, lightweight, 600 by 450mm galvanised lid and frame. It was too small and was bodged in place by some poor cement that overhung the edge of the neck as it was too small. Anyway that as rusted through and needs replacing preferably with something right for the job. But I am having trouble finding anything. I have had a look here https://www.drainagesuperstore.co.uk/browse/underground-drainage/manholes-and-grates/pedestrian-manhole-covers.html The only one that looks suitable, is the bottom right an 600mm by 900mm but is a lot more expensive and in any case out of stock. I would have thought a 600mm round drain cover would be a standard item?

If plumbed wrongly, there is a risk of "swapped contents" I think it was @joe90 that first mentioned this some time ago.

"Plug In Solar" is a name of a dealer. It does not mean it comes with a 13A plug on the end and you just plug it in to a socket. Though I bet some people make the mistake of connecting it that way?

There is no FIT any more, that finished (for new applicants) a couple of years ago. So any solar PV you install now is for your own use. If you pay the premium and pay for an MCS install, and have a smart meter, you might qualify for a mere 5p per kWh exported. So just buy te cheapest you can and get an electrician to install it. You should be able to get a 4Kw system for that. Keep an eye on ebay, you may be lucky and find a complete system for sale near you.

Looks like when this rain stops I will be going and checking the air blower is working and blowing bubbles properly........

So what happens to the shower trap level when you flush the loo in the cloaks? The plan does not help much without seeing a plan of how the pipes are actually connected.

Yes, I have a relative who boasts at how long since his tank was emptied. It seems counter intuitive to me that a treatment plant with all it's working bits does not "digest" the waste better. It's almost as if the cleaner effluent from a treatment plant demonstrates that it is better at separating the liquid and the consequence is it leaves more solids behind so need desludging more often. I am pretty sure a treatment plant would not go "forever" without desludging. We will try 2 years next time and see what the verdict is from the tanker driver.

I think what surprised me was the septic tank, also at 4 years did not seem to be an issue other than the fat, yet he was adamant that our treatment plant was well over due. So for some reason I am sure someone else will explain, a treatment plant is less forgiving if you don't desludge it often enough.

I have fitted a couple of these in Offices where they just want a sinkfull of washing up water. https://www.ebay.co.uk/itm/183802471233?epid=1161120738&hash=item2acb7b2341%3Ag%3AvgQAAOSwxeNgL~bl&LH_BIN=1

What is the detail of the wall make up? I see a flaw there. the gap between the door and the tile edge, lets any water that gets through onto the top of the wall that the door sits on. I had exactly this discussion when fitting my slider recently. Our door is set further out, so any water that gets through between the door and (in our case) decking runs down the front of the wall (protected by DPC) not onto the top of it. Look carefully at your wall build up and see if you can set the sliding door further out.

I thought I would post my experience of getting out treatment plant desludged today, with some local knowledge for those in the Highlands. Previously we ad used Sureclean in Alness. They got taken over by another company last year who promptly closed down the Alness branch. Shame as they used to charge us about £150 each time, i price I now find was astonishingly cheap. So time to find some others. Euroloo wanted about £450 Ouch. Scottish Water and Hielan Loos both wanted about £250 but had long waiting lists. Eventually we landed with Denholm Macnamee in Invergordon, formerly MSIS. They could do it today (booked last Friday) They charge by the tanker hour and per 1000 litres of waste. So today our treatment plant, and the septic tank at our old house down the road were both done. £518 for the pair. Our treatment plant has been running 4 years now, longer than it should, but last year we could not get anyone to do it as everyone was on Furlough (I argued at the time why was an outdoor job that you do on your own shut down) the guy did say it was overdue and we should not leave it as long until next time. We will try 2 years for the next pump out. The Septic tank down the road never gives any problems though he did notice a lot of fat / oil so we need to have words with the tenant. There was a lump of fat half blocking the inlet pipe which I had to clear.

You might as well make it to just above the roof or the caravan or outside toilet.

Make a shed to store all the "future projects" in.

Not seeing this high demand here, my workload is only just starting to increase from the doldrums of last year.

You don't need a P trap, the toilet has it's own trap, so trap following trap is a bad idea. You just need a Y branch to take the 'van toilet in one side and the outside toilet in the other. While you at it put in a 90 degree branch to feed a vent pipe that you can strap to the outside of the outside loo building to vent the run. Depending on the eight of the existing pipe, you might need a raised platform for the outside loo.

Happy with this Rationel triple glazed lift and slide door I just fitted, timber frame aluminium clad.

Floor or wall, however it fits best bearing in mind you need access for filter cleaning / replacement so you need space to stand or kneel while servicing it.
