I’d get in touch with the supplier, they should be helpful in advising your options with your specific joist layout/size/depth..

Aico are about 150mm Dia, so a 50-60mm hole for hiding/retrieving a driver should give you room for fitting the smoke alarm base, if you cant use the manufacturers holes then I doubt you’ll get shot for making your own fixing holes.

As my MVHR unit is loft based, I constructed a small floor to ceiling cupboard in my sons room for shoes and the like. At the back of this is a 300mm*500mm void which I pass a bunch of ducts and an SVP stuffed with sound insulation as best i could. All through egger ontop of posi's. Personally I wouldn't cut each hole individually. Edit, All this is within the heated envelope of the house.

I’ve not seen a base like that one tbf, being pragmatic about it, if it’s grey water and it flows without stalling then I don’t see a reason to change. Don’t understand why you’d need a swept bend, the chamber is fine as that provides a bend between in and out.

Just trying to figure something out and could do with some confirmation. I have an island and it will have a worktop downturn at both ends. Do I still need end panels? I'm thinking not. But I've been sent a couple, and am trying to work out whether to raise a return or not...

used 22*100 rough sawn here, 22*75 may have been better, but it gave plenty of scope for board ends... Other thing I'd note would be working out lamp, mvhr duct, aircon, speaker placement beforehand to eliminate any potential clashes.

Trimmed some end panels and have some non faced edges that I’d like to protect. once upon a time it used to be pva that was used to protect them. But since times have moved on and it’s been shown that pva is no good around moisture could I paint on sbr instead? I’m guessing at this point so please put me straight 👍. ta, marek

Cheers, I'll have a go at that...

When joining kitchen units together, is there a standard practice for placement of connectors. I'll be putting one connector behind the back panel... Ta

Straight away, so likely my fault, or has been pointed out the wrong washer used!

Probably not... Application was both gerberit, and grohe cisterns...

I didnt have a great deal of success with those fittings, I'm sure they are fine but this ham fisted eejit had a failure on the washer. I used the 1/2" to 15 female coupler with a street elbow instead.

potentially use a 2 gang socket extension to bring out the metal work form the backbox that you use to fill into and upto, then remove when all filler is dried. ML Accessories | 2G16EXT | 2G 16mm Galvanised Steel Skeleton Extension Box | Superlec Direct

Number 4 for me

5, if the same as jackoboards, their instructions suggest one in each of the corners and 1 to the middle.
