Hello I have fitted a Nest 3rd gen to an older Potterton 24HE combi boiler. It’s wired as per the instructions from Nest. The hot water won’t come on unless the temperature is increased on the heating using the Nest. Is this normal? Many thanks

Hi I have a small retaining wall (7 courses high, 100ft long). I need to put a 6ft close board fence on top of it. The wall has substantial footings about 12” below ground level. It used to be a 7ft wall. Would I be ok using bolt down metpost brackets on the footings. Then postcrete to ground...

I have an electric shower (Triton T80Z 9.5kW) and a gravity fed system. I also have a pump in the airing cupboard which is being fed from the CWST to the shower. The mains water pressure is good. Why would this pump have been installed? Why wasn't the shower just fed via the incoming mains...

Hi, I'm in the process of laying a new block driveway. Just about finished putting the 150mm Type 1 (granite) down and have a couple of tons left over. I'm putting 100mm of lean mix on top of the type 1 before the sand screed and then the blocks. Over kill I know but it'll have a couple of...

For some reason the boiler seemed to think an outside temperature sensor had been fitted. The fault code 18 is "Lead break, outside temperature sensor". Being the constant temperature model it has never had one fitted so not sure why the code was thrown. It was easily sorted once I'd...

A quick call to Viessmann Tech this afternoon and all sorted. Thanks to Hugh :D .

Hi, We have a Viessmann 222-f boiler which has a fault code '1 18' 'broken frost stat cable'. We don't have a frost stat and can't clear the code. We've acknowledged it but it keeps returning. Also has the snowflake icon on the display. Anyone know how to reset it? Cheers, J

Thanks for the suggestions :) The other cold taps are ok, they're off the CWST in the loft.

Hello All, I fitted a new pillar tap to my cold water supply on the kitchen sink. Now when the tap is opened the water flows briefly before banging then stopping. The pipework from the stopcock tees off to a washing machine valve then to the sink. I've removed the tap from the flexi and...

Yes he's agreed it. Yes, he's happy. Yes, he trusts me. Yes, he's going to test it. Yes, he's going to sign it off. Yes, he's my bitch.

Cheers Ban, Don't worry, I'm getting it all done properly. I'm just doing the cable runs, lifting boards, channeling out etc. The whole house is being rewired so leaving all the connecting to the spark. I've used the MK Grid switches before. Would it be ok to have a 2 gang one of those on...

Hello All, I have a single electric oven which is rated ok to connect with a 3 pin plug. I also have a gas hob which only needs power for the piezo. I'd like to 'hard wire' both of these rather than have 2 sockets taken up with them plugged in. I've got the opportunity to do it properly...

Could you build the new roof at the same profile as the existing with a valley where the two meet? Like an inverted 'W'.

Thanks guys. I think the chance of hitting a fibre optic cable are pretty slim. We've only just been introduced to the wonders of broadband that actually works :mrgreen: . There is a BT cover (large manhole type) but that would be left between the fence and the road so there would be no...

Hello All, Our front garden is bordered by a 4ft hedge which we own and runs parallel to the road. Between the hedge and the road there is an area of grass approx 5ft in width. This land has not and never has been maintained by the council. They maintain the opposite side of the road which...

I'm having recessed downlights (x3) fitted along with a shower extractor fan with a light built in. All to be controlled by a PIR. The extractor is an inline model. It's a ground floor bathroom and the ducting will route approx 500mm before going through an external wall and into a garage...

Cheers. 125 is the stuff I've been using. Must be something I'm doing wrong :oops: . I use CT1 all the time at work. Thought it was just a grab adhesive and sealant. Didn't know it could be used as a caulk.

It was.

Hello All, I've replaced the door facings and skirtings in our hallway with soft wood mouldings. The timber was left in the house for a week to allow it to get used to the ambient temperature etc. Do I need to leave it any longer? I have used various caulks in the past, the last one was...

Cheers mate. Tracked it down to a dodgy neutral in a cheap junction box.
