Many thanks, I will carefully clear the header tank of water & sludge and then I am going to replace it.

I am going to change my loft supply tank. I will be fitting one (or two) of those B&Q "ciffing" types at 190Ltr. Thing is to get a good head for my new mixer shower (not yet fitted) I need >= 1m head. So I am going to raise the new tank and the next convenient height gives me 1.5m. OK. This...

1. My old tank has no cover and I want more space in the loft. Is 50 gal. the right size and can I use one of the types with no lid (like a box). Any advice appreciated. I've seen some in B&Q. 2. My CH feeder tank is full of sludge and with mould on top. What is the best way of clearing this...

Has anyone costed ripping out the Oil system and replacing with Electric storage? This would save a hell of a lot of oil costs and the maintenance charges over the years!

The CH system is with an oil boiler Grant eco 21 series and has an expansion tank but is not a sealed system. Can I just drain the system, fit the pipework to the repositioned rad and turn on the loft feed tap to refill? If it not so simple is there another way to do this (I was thinking...

Thanks, yes I can see that would be the case. What I don't understand is that this "expansion joint" is adjacent to a corner where the outer wall turns around to the next properties external wall due to the properties being offset at their party walls by about 1m. Unless this filling serves some...

I have a 1970s end Terrace and it is built on a concrete raft (stretches under all 6 properties). The internals are either concrete or Breeze block and the outside walls purbeck stone block. At the party wall junction to next door there seems to be an expansion joint filled with some sort of...

Thanks so better cable best then. So what if the earth goes dis. in service - it would seem to be a potential hazard!?

Steambod implies just and ordinary 2.5/4mm T&E! Is that right? Another thought with a 16A MCB at the CU end and a RCB in the garage, what detects if the earth becomes disconnected?

What are my options if I want to suspend from the house to garage about 20m. 1. Type of cable? 2. Strain wire needed? 3. What type of cable run on walls either end? 4. Ordinary 2.5mm if in plastic conduit? 5. Need for armoured cable anywhere? Thanks.

In my bathroom I have an old unit and this seems to be fed from the lighting circuit. It is marked as 650/750W. Is this wired correctly? It works OK.

Well, I am not going to bother powering the garage. I've decided to buy a good extension cable and run it down to a plug in the porch (already there). Then there will be 4 sockets for the power I need. For the bathroom I shall have a mixer and do it soon before some quango decides there are...

Thanks BAS, I have ordered some library books. I feel competant enough to answer the questions but I do need to come up to date on this subject. Thanks fo the advice about the limitations of the forum. I will ask specific questions later but just put those (on the last) post to see if anyone...

Good point I will cost carefully but I guess the garage installation will take 1 day (£250?), the shower 1day (£250?) and the kitchen sockets 1 day (£250?) say £600 for all three as a deal? I could save that! I like the challenge of answering those questions. Sorry "BAS" but that response, if...

I have a full set of requirements from the LA electrician which I need to answer. As follows (for your interest): The following information should be provided before works commence on the electrical installation:- 1. Design documentation including the following: (A) Supply...

Very interesting about the earthing. I have a 1970s house that has not been altered in any way except a new CU. In that CU some of the wires have been lengthened using a simple conn. strip join as they would not reach. Can I fix the armoured cable to my garden wall to save burying it? The...

Thanks for all your replies. My conclusions so far as follows: Robgers, I am having the circuits tested by the LA electrician when I have done the work. I have been doing self build for 40 years now and keep informed of the wiring regs. flameport, I will combine the door bell with the...

I have read many of the posts for garages. I want to install a 4mm armoured cable and have the following I need advice on: 1. Firstly on the MCB (bus fed from 100A switch) side of the CU (split unit) I have: - Door bell - Cooker - Central Heating (I assume just the boiler circuit). -...
