    Replacing a Danfoss HPA2 (4 wire??) motorised valve

    Happened again. The motor doesn't move the manual override lever, so no idea how it's getting stuck like this: I hadn't seen you could buy just the body (I knew you could buy just the head, as that seems a common repair!) - not sure it would be worth the cost saving for the peace of mind of...

    Replacing a Danfoss HPA2 (4 wire??) motorised valve

    Hi, Our heating got stuck "on" - the thermostat was off, even switching it to off at the controller stop the heating. Seems this can be one of the motorised valves being stuck open. This seemed to be the case, I checked the valves and the CH valve was in the manual override position (the...

    Insulated slab joining with EWI

    I was wondering if my plan for DPM is sensible. The rendering will cover the external wall insulation, and I'll just take that down to ground level. There's no point covering the insulation below ground level, right? I've been considering raising the slab a bit, so if there is a gap between the...

    Insulated slab joining with EWI

    I've got 120m of rebar to reinforce. But no, hadn't considered the thickened edge. Was going to just do a floating raft like this: https://www.greenraft.co.uk/ But from reading, you're right I really should have a thickened edge. I was planning on 150mm thickness for the slab, seems 300mm...

    Insulated slab joining with EWI

    I'm just ordering for building an insulated slab foundation for a garage/workshop. My plan is to lay XPS insulation in the slab and have it join to form continuous insulation with external wall insulation. I'm just wondering whether it would be best to build an insulated form for pouring the...

    Applied osmo hardwax oil on too thick?

    After spending many weekends laying and sanding a parquet floor I brushed on some osmo hardwax oil last night before bed, hoping to come down to a glorious finish this morning! Sadly, I'm really disapointed in the finish. It's patchy, and full of grey/white streaks. After doing a bit of...

    Options for laying over uneven flooring

    We replaced one really dodgy joist and an area of floorboards.

    Options for laying over uneven flooring

    No idea if this is good or bad: Looks like the big that's raised up is only one side of the joist

    Options for laying over uneven flooring

    Yeah, next weekend I'm going to pull the rest of the board up and hopefully see the ends of the joist, and try work out if I can plane it. Floor seemed sound - only one board squeeks in a different location where some board had been replaced. There's no noticeable movement in this location, but...

    Options for laying over uneven flooring

    Maybe it is just the one that's high actually... Hard to tell!

    Options for laying over uneven flooring

    They look to be reasonably level with each other the on either side of the "peak" Doesn't seem to just be one joist that's high. Looks like whoever replaced the joists did a terrible job... It's not deep enough to get access. I think they put 3 joists there because it was always a peak...

    Options for laying over uneven flooring

    I'm planning on laying on solid wood parquet flooring in our hall. The current floorboards are not in great condition so, after doing some reading, I decided to lay 12mm ply to remove any irregularities etc and glue down solid wood. Now I've come to lay it I'm concerned about the larger scale...

    Boiler fan on the way out - safe to DIY?

    Thanks for the advice, and confirming my gut feeling I probably shouldn't touch the thing. I'll get someone in. At least a bit of oil in the bearings has made it a nonemergency and I can get some quotes and shop around a bit. And yeah, slip of the tongue\keyboard. I know its carbon monoxide...

    Boiler fan on the way out - safe to DIY?

    The boiler fan is on the way out. The wife lost central heating/hot water today and panicked and rang in a plumber, who diagnosed a dead fan. Quoted £300 to fix, along with a bit of a dodgy refilling/pressure filler (still works okay though, and had always been a bit slow). £180 for parts, £120...

    Is this Asbestos

    Worth getting it tested, our neighbors roof looked almost identical and overlaps our garage, I inquired and they had a sample taken and it came back negative, it was just an old alternative fiber cement. Treat it like it is, until you send a sample off and get confirmation though.

    Building wall with 5 degree slope for rafters

    Hi, I'm re-roofing the garage and increasing the existing slope to a 5 degree pitch. I'll probably have to knock off the top layer of blocks and build up the new gable structure. I'm hoping to embed the joists in the wall, but I'm not sure the best way of building this 5 degree slope and...

    Adjacent garage roof... Asbestos?

    Yeah, I've been having a look and its something I can do and take to the local tip. I'd have to shave the beard off for a mask though, damn. Problem is... it's not actually my roof. Most of it is on someone eases land. I'd have to start taking up whole sheets and significant parts of their...

    Adjacent garage roof... Asbestos?

    I think the images are really huge, so it's made the text tiny! I'll try fix it (edit, think I have?) So it's definitely asbestos. Damn. Really throws a scanner in the works. The annoying thing is its not even my roof! Not sure what I can do about it. The local tip accepts small...

    Adjacent garage roof... Asbestos?

    Just about to order some box steel to reroof our garage and I went up to take some last min measurements and noticed that the neighbours garage roof actually extends a few inches over ours. The problem is I was going to add a few blocks into the wall in order to raise the rafters and...
