We have a dorma bungalow which is about to have a new boiler, the plumber needs access to this roof void to put 22mm heating pipes in the corner, if access cannot be achieve easily either the ceiling will need to come out a little, or the piping along the ceiling. Can the roof tiles be removed...

Sadly this boiler does not cut it anymore. It takes ages to heat the rads, there are 9 rads in the house, 4 bedrooms, 2 bathrooms, lounge, study, dining room, kitchen etc. The house had an extra bedroom in 2006, the heating was not upgraded just extended. This is why we need a combi, the hot...

No, its flow and return. Picture 1 and Picture 2 are the radiator. I had the rad off tonight, the valve key thing that I picked up from Screwfix is too big. I get what its for now, anyhow its no good. Ive cleaned the rads out with a hose pipe, a lot of sludge came out which was good. Ive...

Morning, Appears that the new TRV's are not the same size as the old connections. The old valve has a longer body, which means the copper pipe can be shorter. I can put the new trv and oliver further up, but that's not good practice. One of two things need to happen - a) Extend the copper...

How do i get the old tail out? I cant see a nut to put a spanner on?

Thanks, i have a boiler change coming up. We wont be able to balance the system without a lock-shield.... £6.50 for a TRV and Lock-Shield from Screwfix, not the best quality (Drayton Liquid) but its a start..

Can i re-use the nuts on the copper pipes, or do i need to remove the nuts/olives and use the ones provided? I assume these will be satis - http://www.screwfix.com/p/15mm-angled-trv-with-lockshield-white-chrome/31811 I know they are cheap, however ideal for a tester

Thanks, that's nice to know. I can see that the connection (Tails?) on the Rad will need to be changed on one end. Are these normal sizes? Where can I buy one from?

In short, I think I have old radiators which may have a 3/4" thread, I can fit a bush to reduce it to 1/2" which will enable the fitment of the TRV, however I have a concern about the distance of the new TRV. This picture shows the old radiator connector, without TRV. This picture shows the...

Hi all, Old Ideal Mexico RS30 - Heat Only, Water Tanks in the airing cupboard etc. Upstairs Rads - Piped under the floor Downstairs Rads - Piped through the concrete floor. I guess it is what is it, and the loss of pressure in the combi indicates a leak, and it would help running new drops...

A question of the unknown really, a System Boiler which is being swapped to a Combi. The plumber has commented that a Combi being pressurised, may find weaknesses in the plumbing and pin-hole the pipes. If this happens, the work is of course extra to rectify. Is this something that is common...

I guess time will tell, eventually as we redecorate all old cabling will be replaced. We just hope that we can pull the new cables up the existing conduit/capping. Just leaving minor filling where the back boxes have been removed. I see 50mtrs of 1.0mm T&E is £18 odd. Is there anywhere...

Emf induced by the lighting circuit due to cables within the same capping/conduit? The house currently has a 4 way board, which is built up of 1x Ring Main, 1x Lighting Circuit, 1x Immersion, 1x Cooker (which is the kitchen sockets = bodge). The plan in the future is to have a 10-way dual rcd...

http://m.supremetechnology.com.au/mobile/Product/ProductDetails.aspx?ProductId=613 Hi John, It's a Fluke T3 tester. I should of broken out the multimeter.

Not to be distracted by the Live-Earth waffle, that was probably caused by a light being on somewhere in the house, the board not being turned off. Therefore the churp is the PME connection... The question is DC voltage from the spur..

A bit of a strange one... Recently I have installed a few extra sockets (7 doubles) in the stud walls upstairs. The sockets were run with a view to extend the ring main at the single socket on the landing. One leg was going to pulled out and Junction Boxed, and the other pushed up the stud...

Thats for the replies, The plan could be to have a soakaway, with a high level pipe going out to the surface drain system. A design where it will attempt to soakaway, but if the soakaway (i.e. Crates) are full then the water has to go somewhere. If it does not go somewhere, it floods onto...

No point, we have a surface sewer... We have Surface and Foul...

Rear garden floods, which then runs onto the patio area. The soil is clay, I have dug a large hole 1mtr deep roughly and its still clay. Appears that a normal soakaway is out of the question, unless its going to be huge, then it would just be an underground water storage facility. Has anyone...
