plumbing and heating

This will most likely be a stupid question, how does this fitting work? Do I literally just thread it on my pipe? What kind of connection is this called? Thanks

I'm planning on relocating the pipes for radiators 1 & 2 to make way for a steel beam. Radiators 1 & 2 will branch off the main flow and return between radiators 3 & 4. I noticed the flow & return leave the boiler in 22mm copper and steps down to 15mm copper before the first radiator, this then...

Hi Everyone, I have a question with regards to a specific requirement I have for an electric 3 way diverter 28mm valve on an ASHP installation? As far as I know most 3 way valves are configured so the flow comes into the bottom of the 3 way valve (Inlet: C) and then the water either flows out...

Hi, I have recently moved house and I want to screw in a large set of bookcases into my bedroom wall. The problem is that through the wall is the bathroom and I am worried about hitting any pipes.

Hi Looking for advice. Customer has a back platinum combi 28he and they have one floor with 5 rads and top floor with 6 and the last couple of rads on the top floor don't get hot enough. I've balanced them and got the last rads on the pipe run Luke warm. Wondering if I could fit a secondary...

Customer has a gas boiler. Shower only gives out lukewarm water. All taps give out hot water. Have replaced the thermostatic mixer valve previously & the shower then worked perfectly. however over a period of weeks to months it gradually dropped in temperature back to where it is now with it...

Hi everyone, About a month or two ago we noticed that the F and E was overflowing quite a bit. We also had some rusty coloured water. I can see now from research that this would naturally point to a hole in the coil. I had a plumber out, who I wouldn’t use again because he seemed completely...

Adding a vertical rad into our new extension. I noticed the pipes were centered in the wall which I didn’t like so I asked the plumber could we move the rad closer to the corner. Does anyone know of this affects the efficiency of the rad? We were told by moving it closer it would reduce the...

Hi all I am just wondering which setup do plumbers/heating engineers like the best out of these 2 systems with CH header tanks in the Loft? - and is one better than the other or do they both work as good as each other , any caveats with either? *Diagrams not - no-where near - drawn to scale...

Trying to connect Vado Capsule kit to overflow. The issue is when I am trying to install either of the 2 waste adapters it came with to my existing McAlpine overflow they don't fit. Has anyone installed one of these and has the same issue?

Hi, This is my radiator in my bathroom. I want to change it to a towel rail. As a chippy I’ve done fair bit of plumbing but want advice on changing this. What would be the best pipe lay out? It’s a 500 rad getting changed to a 500 towel rail. I know the tails come underneath. Could I put a...

I have an issue with my Salus thermostat (model ST620RF). All of the sudden, the lights on the receiver have gone blue and red (dimmed) and the heating and hot water stopped working. The thermostat has new batteries and is working fine as well. I have tried multiple times to re pair it and reset...

Hi, My heating is switched ON. 3x of my radiators TVR valves are OFF. BUT the radiators are still coming ON. I’ve checked the TVR valve and they are working, the pin is opening and closing they are ok. It seems really odd that this problem started at once, any idea what this could be...

Hi, Could anyone tell me if it is ok to up the size of pipe from my radiators from 8mm to 15mm? My current configuration is 22mm from the boiler then it downsize closer to the radiators to 8mm. I would like to upsize from the 8mm to 15mm but in my head i dont think its possible. Might be...

Hi, I recently had my bathroom renovated (including installation of a new towel rail) and ever since a radiator in one of our bedrooms has stopped getting hot. The only way we seem to be able to wake it up is by turning the overall heating up REALLY high. Any idea what it might be? It has...

Hello. So I’ve recently moved into a 1900’s terraced house with a loft conversion from 2001. The shower in the loft is either scorching hot or Luke warm. It also had problems with being jammed stuck until I loosened it with WD40. However, as it’s the loft, it’s not a priority (I imagine a...

As in the title - What's the required insulation under building regs for heating pipes in the unheated loft space within a residential building? I can't seem to find any clear-cut answers.
