Hi all, I have a Grohe Grohtherm 800 bath shower mixer tap fitted approx 3 years ago. Been working fine but it's now dribbling from the tap constantly and won't turn right off. I assume there's a fault with the cartridge? It only leaks when hot water supply is turned on, not when just cold is...

Hi Just fitting my Nest 3rd gen thermostat, it requires a 12v power supply, mains power is obviously too much and will kill it. Its located just above a double socket (ring main), is there any way of coming off this socket with a wire to power it? Found this 240v to 12v reducer, what would be...

Hi. Just had an external oil combi fitted, W-B greenstar heatslave II 18/25. I'd like it to be controlled via smart thermostat but struggling to understand which one would be best. Rads are all on standard trvs, not smart trvs, so no individual zones for house controlled through thermostat...

Is this right? Socket once screwed in isn't flush like it would be with a drylining box. Is this to allow for plaster skimming?

Can anyone recommend one, not too pricey, that'll handle a light & inline extractor? Also, opinions of these? Reliable? Thanks.

Hi If I lined some wall sections with a layer of this would a skim coat of multifinish plaster be sufficient to cover it? What depth would I need to go? It basically 6mm cork. https://www.diy.com/departments/diall-acoustic-thermal-insulation-roll-l-5m-w-0-5-m-t-6mm/1906876_BQ.prd Cheers,

This stuff claims to be as effective at insulating as 65mm mineral wool... Airtec foil. Is it fair to assume it would be a better insulator than polystyrene boards such as these 25mm boards? It's for internal wall insulation, specifically around window reveals where space is tight. The foil...

Hi Property I bought has a fireplace in lounge and another in the bedroom with flues up to a chimney stack that has been dropped below roofline. As far as I can tell the chimney is not ventilated at the top where it's been dropped. The fireplaces are still open so warm air from the house is...

Hi Got uPVC sash windows, they all have this on both sides but I've no idea what it is?

Hi Looking for a way to improve drain flow rate for a shower tray. When shower is on full it's really struggling. With the chrome cap on it doesn't drain fast enough and water will fill & spill over sides. Without cap it just about copes.. just. Was going to fit a water aerator to the shower to...

Hi Had a composite door fitted about 6 months ago, however it's a tight fit about halfway down and needs a good slam. Before I get the form out to have a look I wanted to try and sort myself. It's the right about halfway up on handle side. The hinges inside have an allen key adjuster at the top...

Hi Will a 125mm inline fan suffer much of a reduction in performance if connected to 100mm ducting? Thanks

Hi Are there any restrictions on the siting if an external oil (combi) boiler? I understand there are for the flue/outlet etc, but what about the unit itself? In the photo I've marked a space that is approx 400mm from house wall at the side. Boiler will be installed against kitchen extension...

Hi I understand adding internal wall insulation increases the risk of interstitial condensation within the walls, however I've heard that it's only really an issue if adding a lot of insulation and adding less negates the risk, is this true? I'm planning on adding 50mm Rockwool to solid stone...

Hi Had an issue with a socket last night. It briefly made a weird fuzzing sound before tripping the switch. I shut off power and opened it up, the neutral was loose in the terminal, which explains what happened (intermittent connection causing arcing & tripping switch?). What I don't understand...

Hi Not sure if this is the right section for this question? How long after a concrete slab is laid can a heating oil tank be fitted on top of it? Slab will be 100mm thick, 2.5x2.5. Tank will be a 1200l plastic low profile tank. It won't red filling straight away so will just be the weight of...

Hi. Just had a quote for a concrete slab to be fitted. Size is 2.4m x 2.4m, mot 1 + 75mm concrete, trowel finish, £800. Does that seem about right? Was expecting nearer £500 to be honest.

Hi Want to tile floors downstairs using natural slate tiles over a concrete subfloor. Haven't got the money for u/f heating though, so a little worried floor is going to be very cold in winter. Rooms will have internal wall insulation + good level of loft insulation upstairs, double glaze...

Bit of a long shot, but is it possible to get an idea of heat output on a standard style panel radiator? Size is 1400mm X 600mm with 10mm feed pipes. Bad pic of it below. I've found info for them online, but are these ones likely to be very similar spec? Want to know if changing it to...

Hi. Planning on having a new boiler fitted, it'll be an oil fired W/B Heatslave 25/32, will this be sufficient for a 4 double bed house with 2 bathrooms (one with shower bath, one shower shower cubicle)? Searching around gives mixed opinions, some yes, some no. Also, my existing radiator...
