I have a pressure tester and I need to find the fitting to attach it to an underfloor heating manifold. Here is the connection on the pressure tester - I need something that screws into this. The connection that screws into the manifold will need to be like this. What is shown below does...

I am changing the trigger for my boiler from a timer to a wiring centre. The wiring centre is in a different place to the boiler. What cable diameter is acceptable to run from the boiler live supply / return to the writing centre? I have a reel of 2-core 0.75mm2 - would this be acceptable?

When I try to turn on the heating in the Tado sadly nothing heats up. Not sure if my problem is with Tado or the boiler as the hot water works fine. There is a sound of a relay clicking inside the Tado control unit, but as Tado doesn't always respond immediately to heat demand it's hard to...

Please take a look at this diagram which shows the joists under the floor of a 1st floor. The room is partly over a hall, and partly over a garage hence the brick walls below. I need to get 2 bundles of comms cables through this location, both around 25mm in diameter (see red text on diagram)...

I am trying to future proof my internet connections a bit. As such I want to put in place three cables now in conduit for each ISP in my area whilst I have opportunity. What are the different cable types they use? Virgin (I have this now) Coax type cable joined externally in a brown wall box...

All the videos I have seen show that you can use a bending spring to bend plastic conduit 90 deg. Is it possible to bend it only 30 or 45 degrees ?

I need to dig down the solid floor of my 1930s property to install under floor heating. I need to do this to get the heights level across the various rooms - I cannot get a "lay on top" system to work despite best efforts. The system will look like this - exact model not shown but it is the...

I have used mechanically fixed insulated plaster board in some rooms I have renovated to good effect. However, I did not use any sort of vapour barrier and unsure if I should have done. The external walls are what I believe is solid brick - that is, two courses of 100mm brick with a few...

Hi all, I am revisiting my plan discussed here https://www.diynot.com/diy/threads/filling-void-under-suspended-floor.615142/ to fill my suspended floor. I dropped a tape down into the floor and found that from the bottom to the top of the finished floor is 700mm. What I am thinking: 700mm -...

I am thinking about installing between joist UFH in an old 1930's house with 200mm solid walls. The room I am looking to fit it to is as follows: 18m2 floor space 2.6m height 2 external walls one which contains a large bay window which has pretty crap efficiency due to metal internal spacer...

I am planning an extension and a rework of the heating system. The house currently has a combi boiler, radiators in every room with a Tado TRV system (which has worked really well for the last 5 years). The proposed system will be a system boiler, water tank to support two bathrooms and...

I would like to get opinions on if I need an architect, or an architectural technician for my proposed extension. The house is a 1930's detached very typical of many houses built in the interwar period between 1920 and 1938. This picture is not the actual house but you get the general idea...

I've got a 48 zone Galaxy dimension and have a question in regard to panic button wiring. I was thinking of getting one of these CQR panic buttons: https://cqr.co.uk/shop/intruder/panic-buttons/double-push-intruder/cqr-padp3_wh_m-push-button/ The spec. sheet says that is 24v and I am sure my...

Hi all, Does anyone understand the purpose of the intruder 04 output function on a Galaxy Dimenion? According to the output functions table (page 6-91 of the manual I have), this function is only activated when the alarm is fully set. If I part set the alarm, then this output function is not...

Just wondering if it's possible to fill in the void under my suspended floors? - two reception rooms approx 16m2 each. - the void is around 4ft deep - various electrical cables need to be considered that go to sockets throughout the room The objectives are to improve thermal performance...

Does anyone have any experience of using an airless sprayer to apply water based undercoat and satin? I've got a Wagner control pro and a lot of doors to paint. I've been using Johnstone's Aqua and would like to continue to use that paint so the colour of the doors matches the skirting and...

Am I able to plug a 16A C19 cable into a UK standard plug socket? The socket forms part of a 32A ring circuit. This would be power an Uninterruptible Power Supply in my garage. Thanks in advance.

I live in a 1930's house and have finished renovating the upstairs and have fitted white primed DX30 doors. The upstairs frames accepted a 1981 x 762mm (30") door. I did not realise the downstairs frames are slightly wider at 813mm (32"). I can't find a matching door with a width of 813mm...

I bought some of this felt wool lagging from eBay. I need it to stop some pipe making noises on the joists when the pipes expand and contract. I noticed that this is felt wool interwoven onto a black plastic film. Is this safe to wrap around pipes that will get hot?

Hope I've got the right terminology here. I believe the piece of vertical trim is covers the "coupler" between the window units and the door frame? Does anyone know the name of this profile and where I could possibly get some? Thanks in advance.
