    110mm AAV with wrongly sloped horizontal pipe or 40mm AAV

    I’ve seen that one, but if it works with a 32mm pipe doesn’t it just mean that the extra section of a 40 or 50 mm pipe would go unused? I might as well use the 40mm leftover I have then

    110mm AAV with wrongly sloped horizontal pipe or 40mm AAV

    Is 50mm a standard pipe size? I’ve only ever used 40 and 32mm

    110mm AAV with wrongly sloped horizontal pipe or 40mm AAV

    I am in a bit of a pickle with the AAV. The soil stack in on the left corner behind the bath (see pictures). Previously there was a section of 40mm pipe on top of it with a small AAV. We never had a problem with it. I understand 40mm don’t provide sufficient air flow (although we never had a...

    My 170cm bath tub is 169cm, how do I fill this gap?

    Is it sufficient to glue it or do I need mechanical fixings? The 20mm boards are dotted and dabbed + mechanical fixings, which where a nightmare to fix to the hollow blocks behind

    My 170cm bath tub is 169cm, how do I fill this gap?

    I installed 20mm backerboard to the side wall to bring the space to 171cm (to allow 1cm margin for installation and tiling). Now I realised the bath is 1cm shorter. Can I glue another set of 1cm backerboards to the existing one to close the gap?

    Door frame standard internal width for a 686mm door

    Hello, I checked out and measured door frames in Wickes and I found two different answers: MDF door frame: 691mm for a 686 door Softwood door frame: 688mm for a 686 door The softwood seems tight with only 1mm clearance per side, unless they swell when painted?

    Door frame standard internal width for a 686mm door

    I need to build a door frame for a 686mm door. The reason I’m doing it is because I want a transom window and I’ve made the wall thicker by adding tile backer boards. I’ve measured the door and it’s actually 684mm wide instead of 686, the door is new. Is 686mm the width of the frame or...

    Qboard basic vs Qboard waterproof

    Hello, I need to buy tile backerboard for my bathroom and I’m thinking of buying the QBoard from B&Q. I just don’t understand the difference between these 2: **Qboard Basiq Square edge 20mm Backerboard (H)2400mm (W)600mm**...

    Plywood arrangement for bathroom subfloor

    I already have the two structural plywood boards. There are no noggins at the moment, in this house they were only in the bigger rooms (floorboard offcuts). Not really feasible to add them now as there are pipes. But could still add some timber at the top and bottom of each pair of joists, then...

    Plywood arrangement for bathroom subfloor

    I have a bathroom under renovation; I’ll removing all existing floorboards and replace with 18mm plywood, which will then be over boarded with something like cement boards or similar before tanking and tiling. I need 2 plywood sheets to cover the entire floor, which arrangement is better, A...

    Insulated backerboards directly over studs?

    I’m renovating my bathroom and I’m building a studwall behind the bath to accomodate some pipes and a concealed shower valve. Do I need to have plasterboard beneath the boards? Or can I screw the insulated boards directly onto studs...

    Replacing shower thermostatic cartridge

    I’ll try and pull it out. The other bit I’m not clear about is that the adjustment white thing that goes onto the spline shown in picture 1 doesn’t fit on the new part. And it didn’t come with one, so there will be no scalding protection (I cannot set a max temperature)

    That’s the temperature control

    Replacing shower thermostatic cartridge

    Yes. They sold me both. I imagine there is a similar piece inside the shower bar that I failed to remove, I briefly tried with some pliers with it wouldn’t budge. Do you mean I need to open the shower bar on the opposite side by removing the flow handle? Also, there was a white plastic bit...

    Replacing shower thermostatic cartridge

    I’m trying to fix a thermostatic shower. The shop that sold it to me originally provided this part, which is slightly different from the original one. First photo: original cartridge Second photo: what the replacement cartridge looks like Third photo: what is this part? With the replacement...
