Gone West

Isn't it a requirement to have a double check valve on entry into the property.

Joint backer rod was discussed on here a little while ago.

I fitted Lindab guttering, and the instructions say that the galvanising creeps back over a cut surface, as long as the metal is only cut with hand tools. If power tools are used the heat build up destroys the galvanising near the cut. We didn't have any rust showing after several years of use.

He could try Fix-A-Floor. https://www.ebay.co.uk/itm/162317653688

Why does a DIY reedbed have to be any larger than a commercial system?

We had a small plot and didn't have room for a drainage field, so we were going to have a deepbore soakaway. The deepbore soakaway turned into a 47m deep well, so we needed another solution. The neatest solution for our needs that we could find, and was acceptable to the BCO, was a Klargester reedbed system. We used the supplied reeds for a year or so but they were very vigorous. We were told we could use irises instead of reeds as they had suitable rhizome root systems and grew less than half the height of the reeds. We never considered willows as they would not have been suitable for the reedbeds we had.

IIRC it was around £2000. It worked fine, no smells, but you wouldn't want children playing in it. The maintenance consisted of thinning out the reeds every three or four years, which you had to be careful when doing, as you shouldn't get the water in any cuts, so it was a Marigolds job.

I wouldn't say huge. We had a Klagester Reed Bed System, for six people output, it was two tanks, IIRC 2.5m long by 0.8m wide and the BCO sanctioned the tertiary treated effluent to be piped into a soakaway. https://www.kingspan.com/gb/en/products/water-management/reed-beds/

Would have thought the Dewalt website was your browser homepage 😁.

Yeah, we found it 'interesting' positioning a 1.5 sink, and tap infront of the window with a flying mullion. It's all good fun.

When your A2A is defrosting, does it just turn off the indoor units.

Welcome to the forum, good luck with the renovation. Stormdry is one type of treatment you could look at.

If you don't mind me asking, what type of stone is it and does it have a particular name.

I think I did mine more or less 50/50 with the tap positioned central but so both windows would open. The sink was fixed with G Clips. https://www.gclip.co.uk/Undermount_sink_installation.html

I doubt it, looks more like coir fitted to stop the pipes squeaking against the joists. If you're worried you can get asbestos testing kits from Amazon.

I bought a 620mm wet bridge saw for around £150 back in 2010. I did all my floor tiles, roof tiles and sandstone paving with it, and at the end, the bridge bearings were knackered so I gave it away. Used several blades but always got clean cuts with no chips.

We only had two trades who I considered to be very good, the plasterer/tiler and the carpenter who did the cladding and plasterboarding. The first carpenter, who was recommended, was useless, so he went on the first day. Others I let go and did it myself. I ended up doing the studwork, electrics, plumbing, kitchen, bathrooms, flooring, doors etc. The reason it took eight years.

We had a Genvex Combi with an EASHP and when we had a problem with it we used Isoenergy who were excellent. We were in Kent and they are in Surrey, don't know if that is your area. https://www.isoenergy.co.uk/

I think 55% RH is good. It's roughly the same in here at the moment. At the last house, with MVHR, it was around 45% which we also found comfortable.

We didn't have UFH and our bamboo flooring pulled back from the edges in the summer, in the main bedroom, if the sun shone on it for any length of time. The solution was to close the blinds a bit.

We kept our bathrooms at 24C with electric towel rails.

This was a few years ago, but the make was Nikles and I think the model was Pure Tronico.

We heated our EASHP powered UVC to 45C and didn't have any problems with our bath thermostatic valve, nor the thermostatic showers.

We've used 247Blinds several times, good choice and reasonable prices. https://www.247blinds.co.uk/
