Thanks for all the input on this. I thought I would post a reply as it seems to have been sorted. I had plumber out last week to look at this and he "adjusted" the diverter valve which seemed to help as the boiler was firing up when the hot water was put on. Whilst the water was warm it...

Hi there, I am having some problems with my heating/hot water as follows. We have a Worcester Bosch CDi Combi Boiler. Problem 1. When I get in the shower I turn the mixer valve (not thermostatic) fully round to hot but only get luke warm water coming through. I can resolve this by turning...

Pic of cu and main feed. Require would mean recabling whole house. I can simply remove spurs and add additional sockets to existing ring. To fix current issues. I will need to move some sockets as part of the decorating which currently I can't do because I don't have an rcd in the cu.

So I was doing a bit more reading on this last night to work out what would be the best solution. I have 5 circuits in CU (upstairs/downstairs lights/sockets and cooker), and I dont believe that I cn put a single RCD between the feed and the CU as that doesn't comply with regs. swapping out the...

I think I can install a fused RCD like this next to the internal socket then install the external socket on the outside wall after the RCD. the RCD can be used to isolate the external socket. Would this comply?

Have just check and they are plug in circuit breakers like this.

Ah OK. And from a quick google it appears that swapping MCB for RCBO is notifiable?

I did think about installing an isolator but dismissed it when I found out I needed a seperate RCD as i could cut the power to the socket byt throwing the RCD. This would not solve the issue above though so I will install the isolator switch. as the socket is going on the other side of the...

I believe a built in RCD is mandatory on external sockets. As it looks like I have MCBs in CU I will need an RCD fitted socket. I use the Plug in RCD when doing general DIY around the house.

Pretty sure there is no test button. so it looks like MCBs

Have just googled MCBs and RCBO for pics and I think they are MCBs. There are no additional RCDs that I am aware of. I will take a picture tomorrow as my CU is outside the main house and I need to go to bed. Thanks for the input.

Thanks guys. I am in England and I have RCD (trip switch) in the consumer unit rather than fuses. I normally use a plug in RCD when using power tools. If my consumer unit is uses RCDs then should I not use a the plug in RCD when doing DIY?

definitely cant use masonry nails?

Hi Guys, I want to fit an external RCD fitted weatherproof socket in my back garden. I have a plug socket on an internal wall, on the other side of the wall that I want to fit the external socket. I am quite happy with drilling through the wall and fitting the sockett but I cant figure out if...

So I have managed to work out that it is one radiator that is causing the problem. If I lock off the rad that is upstairs and directly above the problem rad. the problem rad fires up fine. I have locked this one rad off to try and clear any locks. I am still getting air out of one of the...

Thank you. I will try to find this.

Hi Guys, Can anyone recommend a paint on Sealant to fix a porous Corrugated Asbestos roof? Replacing or covering are not really an option as it is an adjoined garage roof with 4 neighbors. It was covered in moss and I have cleaned all that off in the summer.

The boiler is upstairs, and all rads are fed from the walls. It is a 70's house with parque flooring under the carpet and I suspect that it is poured concrete under that. It is weird that once it gets hot it will stay on until the system shuts down. I am still getting a bit of air out of the...

Non of the rads have been balanced. They weren't when we moved in 12 months ago and the rad was fine until now. happy to try balancing if it is likely to make a difference? The pipes come out of the rad at the bottom then go 90deg into the wall

Hi Guys, I have been redecorating one of our upstairs bedrooms and have had to replace the Rad valves in this room as they were corroded and would not lock off to remove the rad. I drained the system down from a downstairs rad in the dining room as this was the only place I could get a...
