P.S. I asked for 32mm, but according to the mole contractor, it is up to the water company, and if it is on a hotel or a big house, it is usually declined.

Hi Charlie, I had an external water pipe replaced by a contractor using a mole, which saved digging up the driveway. Cost £380 for 15 meters of moling and included a trench that had to be dug through concrete to allow the mole to go round a corner at the back of the house. No inspection by the...

I suppose everyone knows what hardibacker is. i.e. solid cement board http://www.diy.com/departments/hardiebacker-12mm-cement-backerboard-for-tile-stone-l1200mm-w800mm-t12mm/136777_BQ.prd here is an example of the kind of expanded high density polystyrene\fiberglass\cement face board I am...

Hi folks, I need to refit and tile my bathroom. The plaster under the old tile is blown in places so I will have to strip it off. The walls underneath are not very flat so I think I'm going to use a backer board under the wall tiles(20x25x6mm). The wall is an unusual low density cinder...

This link says to use thistle bonding agent(ThistleBond-it) on painted surfaces. http://www.deepingsbuilding.co.uk/downloads/thistle_plaster_selector_guide.pdf Seems to be for the purposes of bonding, rather than suction control, or otherwise that chart would say to use the Thistle...

Hi, Do you know if your loft is a warm or cold loft? I know virtually nothing about building or roofs and so don't recognize the sheet material above your rafters in the last photo. Is it breathable, or ventilated? I think the regulations say that for a cold loft, you need to retain 50mm of...

Hi Folks, I'm going to tile an alcove and cupboard in my kitchen that the previous owners left out and now keep gathering kitchen mess! I'm trying to compile a shopping list of the things I need, I'm on a budget so don't want to buy things I don't need for such a small job. For info, I...

AdrianUK and Lectrician, glad you responded, I thought I was the only one in the country thinking of this. I've searched around on the internet and not turned up very much information on domestic systems. Good thinking about the combined relay box isolation message, I'll investigate if the...

Brilliant advice everyone, I couldn't see the wood for the trees on this one yesterday, especially in the heat, but the thrust is that structural strength is paramount, especailly with the unusual construction of brick walls ontop of floor boards, and I'm worrying over nothing about the heat...

I posted a new message about the cable pipe proximity since the subject of this thread has now changed! Find it here; http://www.diynot.com/forums/electrics/replacing-cables-running-beneath-parallel-to-radiator-pipes.407632/#3154679

Hi Folks, I have some lighting cables that have been damaged by mice that I'm trying to replace. The run I wish to replace travels underneath and parallel to a 4 meter length of the central heating pipes. The current holes in the joists are 50mm below the bottom of the pipes, is this enough...

p.s. the floor joists seem to be made of extraordinarily tough hard wood, although I'm not sure how to gauge that, so I'm more easily persuaded that insulation is a proper cause of action, rather than new holes in the joists. Thanks for any help, I'm not sure who else to ask as everyone I...

thanks for your reply John, Unfortunately family illness has kept me away from thinking about my wiring for quite a while, but I'm back on the Job now! the house has been in a right mess all this time! Looking at the cables for the lighting, some has been eaten by mice whilst the house was...

Thanks for your reply flying sparks! I have a central accessible location next to the chimney and so in order to get rid of the diagonal cable runs and inaccessible junction boxes I was thinking of replacing the lighting set up with a junction box set up like this...

Hi folks, Is adding extra switches to ceiling lights a notifiable change? I currently installing a wired alarm in my new house and would like to use the function that operates a relay on an alarm to turn on a couple of lights in the house. This will enable the security camera to take better...

Must be pretty high energy lights. Do you know what you are talking about? Nope! Not at all! It was more of a question really. The lights are rated at 1200W maximum bulb size, even though they were to be used with 23W CFL lights in. I'm not sure how many 1200W bubs you could run from...

No No No No No No No!!!! Sorry folks, I didn't mean switched earth! What a disasterous slip of the keyboard! I ment switched live!

thanks for the speedy replies folks. Top tip with the 2.25 meters, I had a look at the zones diagram the regulations, but I hadn't noticed the 2.25m hieght. I've got 2.4meters but I am planning to put in an L shapped bath, which will mean that the old shower pull switch is actually over...

Hi Trevor, I'm installing my exterior lights with 3 core and earth hi tuff, as this will allow me to pass a switched earth outside to allow switching the lights on from inside the house. Another option is that some types of security lights come with internal electronic control that allows...

HI Folks, Is there a minimum distance from the bath\shower for a shower pull cord to be located? The pull cord of my shower is next to the bath, so theoretically one could reach from the pull the cord or even touch the pull cord ceiling rose if you reached over the shower screen? The...
