I had my boiler relocated in the loft, and to do this the gas fitter installed the 22mm copper pipe in a stud wall (no I did not do it myself). I had already stripped off the plasterboard. Now I'm ready to reboard the wall, but before I do I'd like to give the pipe some mechanical protection...

I have old style lighting circuits, not sure of the correct name, where each light and each switch is connected back to a central junction box. Does anyone know the correct/standard way of wiring a pair of two way switches for a landing light using 3-core cable with this? All the diagrams I see...

Maybe an odd question, but when I was refurbishing my hallway the other day I found an old electrical cable bonded to the staircase at one end and running to the area of the meter and CU at the other. No longer attached at that end. From the look of it dated to when the house was built in 1949...

While cooking dinner the oven and hob switched off. I checked the consumer unit and the RCBO for the cooker hadn't tripped. It still flips off when you press the test button. There is definitely no power in the cooker circuit as the cooker switch is the type with a socket and that doesn't work...

I'm having my kitchen ceiling replaced so have taken down the plasterboard. All the cables above are now hanging down and will be in the way of the plasterer when he puts up the new ceiling. Should I clip them to the joists to keep them out of his way or use some other method so they can still...

Hi all, wondering if anyone can help with some advice on how to wire a Salus RT300RF thermostat for a 230V application. The catalogue description says it is suitable but the manual only gives a volt free wiring diagram. It's not for a boiler, I want to use it to control the 230V fan in a...

Hi all, before I start I should say to avoid anyone jumping on their high horse this is is *not* something I'm proposing to DIY, apart from the associated works of lifting floorboards etc. I have Instagroup coming next week to install a new boiler. Because it's a big company, it's been almost...

Hi all, I have a question about installing a condensate pipe for a boiler. We're having a new boiler fitted in the loft, but at the moment I'm redoing the bathroom where the condensate will discharge to an internal stack. Rather than put the bathroom on hold till the boiler is installed or...

Hi, I've been looking to get quotes for the replacement of our Baxi Bermuda back boiler before the start of the next heating system. Was thinking of staying with the present vented system, so getting a heat-only boiler to minimise disruption etc. I've done some calculations and 12 kW...

Hi all, does anyone know of span and load tables for steel L-section purlins? I'm considering replacing my roof covering and need to know whether the purlins could safely take the weight of the new covering. The purlins span 3300 mm between trusses at 1300 mm centres. They are 64 x 51 x...

Can anyone tell me if it's significantly simpler/cheaper to install a heat-only boiler for an existing central heating and hot water system than a combi boiler? At the moment we have a Baxi Bermuda back boiler and 8 mm microbore central heating system with a vented cylinder. I'm thinking...

Hi all, I'm looking for some advice on vent pipe removal. I have a boxed-in vent pipe above the soil stack in my bathroom. Due to the room being small it would make the layout much more convenient if it was removed and replaced with an air inlet valve, as the neighbours have done (identical...

What sort of good quality paint would you use to repaint galvanised steel downpipes? The paint is badly flaked from neglect but the metal underneath is in perfect condition.

Hi all, I've been putting off painting my house exterior because of the textured paint that the previous owners had applied which I have never figured out how to deal with. Now though it urgently needs to be done as it is flaking off in patches exposing the bare render, which because of the...

Hi all, I'm looking for some advice on how to restore an old parquet floor in my living and dining rooms. It is original to the house, from 1948/49 but I'm not sure what sort of wood it is. The previous owners had it covered in carpet, which I have taken up. It's in OK condition for the...
