I've just made 2 bathroom wall cabinets from mdf and painted them white with Farrow and Ball Estate eggshell water based paint. They look fine but I'm wondering if i should apply a varnish or some other type of clear finish to give them a hard scratch resistant finish, and if so, which type?

I have a spur from the ring main, terminated in the loft in a fcu. The fcu supplies a load (approx 600 watts) to a shower booster via a pull switch in the bathroom (C U protected by rcd). I want to fit a bathroom wall fan heater (1kw). Can I install a j/b in the loft and branch off a cable to a...

I want to install a wall fan heater for the bathroom, however, I want it to switch itself off after a given number of minutes (just in case I shoot off to work and forget to turn it off). An ordinary timer will be subject to the time I set it to come on (plus pull cord override) and go off...

I need to change an indirect cylinder in my daughters house that is clogged with limescale and about 30 years old. I can get a replacement from Wickes for £150 but I'm not sure what size adaptors are needed. I am assuming they will be 2 females at 1"-22mm and 2 males 1"-22mm. I want to get...

Can you define accessible for me? A ring main joint in a back box with a blanking plate over with 2 screws is visible and accessible. A junction box under a short floorboard screwed down with 4 screws is accessible but not visible. Does accessible mean visible as well as accessible?

A previous occupier has cut into the ring main under the floorboards and connected 2 separate spurs using a jb. It's a dangerous set up that can't be allowed to remain. The ring main cable has no flexibility in it. I can put a socket on the wall in a different place to replace one of the spurs...

I have 2 questions. My daughters new house. 1. I have replaced both (damaged) cables serving a ring main socket. One of the new cables has been taken back to the adjoining socket. The other cable, however, goes back to the consumer unit via a convoluted path and would require dismantling...

I have a socket on a ring main and I need to find the the next sockets on the ring in order to change one of the cable that has been cut and joined with a choc box in the wall (previous householder). Is there a way to find these next in line sockets without disconnecting all sockets and finding...

My very old blow torch has expired. I have a one off (probably) job diverting some 15mm pipes in my daughters new house. I don't want to spend a fortune on a torch as it may not be used again (I'm in my 70's). I have a fair bit of experience soldering copper pipe and a lot of experience as a...

I'm going to overboard my existing stuck down felt roof with 11mm osb. The underside osb decking is in good condition. Would it be ok to nail the new decking to the old using annular nails or do I need to use screws? As I'm doing this alone I need to get it done quickly during fine...

I have a detached flat roof garage with 2 layer felt, green mineral top. I fitted it about 8 years ago and bonded it so getting it off is not an option. It is beginning to crack and I have had to bodge it to stop leaks. The decking is external ply screwed to the joists. Can I simply bond a...

1. I have a fully pumped Y plan with a 3 wire programmer (broken). Can I change it for any 3 wire programmer or do I need to choose a compatible one? (My programmer isn't on any comparison table) 2. Can I by-pass the programmer and change my room stat for a programmable one? If I do this...

I have a 15 year old Potterton floor standing boiler with integral programmer. The programmer has slider controls that no longer function correctly. I would like to change it for an externally mounted programmer. The current programmer has a wire that goes to h/w out, a wire that goes to c/h...

I am intending to replace the laminate floor in my hall. The current edging is 15mm scotia which looks pretty unpleasant when taking a 90 degree mitre around the 8 door frames. Removing the skirting and undercutting 8 door frames (with the risk of damaging the skirting in the adjoining newly...

I have an ageing Potterton floor standing boiler which I installed 16 years ago and it has never faulted. I am considering the time when it will need replacing and what to replace it with. There are only two of us and the property is a bungalow with one bathroom and one kitchen sink and nine...

I recently had my main gas pipe from the meter renewed and redirected. It no longer has an earth bond. The new pipework runs along the outside wall until it splits in two place to enter the house. It would be virtually impossible to run an earth from the point where it enters the house to the...

I have a Proteus split load c/u. There is a circuit to an external garage which is terminated on the c/u with a mcb. Is it possible to change the mcb for a rcd? It would be possible to change over circuits to put the garage onto the rcd load and change one of the rcd's over to the mcb load...

The main earth bond (installed in 1970) to my cu is connected to the incoming water main underneath a bedroom floor at the point of entry. It is not accessible or visible. The earth wire is stranded (6mm i suspect). I would like to upgrade it to 10mm in line with 17th. If i connect it close...

I need to purchase and install a wash basin vanity unit. There is a 40mm waste pipe running horizontally along the wall at floor level (discharge from shower). Are (all/any) vanity units designed such that a small section can be cut from the rear of the two sides to allow the waste pipe to pass...
