I have a Securoglide Compact garage door about 10 yrs old. The rubber safety strip at the bottom has shrunk away from the ends so the safety circuit does not work and you have to hold the "down" button in for the entire distance. Apparently it has two copper wires in it which are shorted...

I have a Honeywell zone valve which just whirrs all the time as if the gear drive is slipping. The manual lever is completely free to move as well, I can't feel it opening the valve like I can the other two in the system. In this thread @ChrisR wrote "your CH valve is stuck partially open. If...

... which is part of a UFH system installed in 1995? I have not been able to find one with the same port configuration. Unlike most of those available on the web the cold input (bottom) is opposite the outlet (top) and the hot comes in at 90 deg. Ideally I would like to fit an exact replacement...

I have a 3.68 kW PV system and would like to use it to power a modulating heat pump of about 5 - 10kW output in such a way that during the day it only draws as much power as would otherwise be exported. One installer has said you can do this with an Eddi. However from example 14 here...

We have a working installation with an old Sky dish (with a rectangular cross-section support arm which the LNB bracket plugs into). I now want to replace the LNB with a quad one, but commonly available types e.g. the Visiblewave seem to come with a non-compatible bracket. I have read that the...

We have a standard 3.6kW solar setup installed in 2011, it has a Total Generation Meter fitted inside between the inverter and the CU. Outside in the meter cupboard there is an old two-rate meter for the E7 supply. Neither of the above measures the amount exported (and it is not possible to...

We have a whole-house rainwater harvesting system (except for the drinking water taps), and in recent years I have had to replace the PRV on the hot water tank (corroded/broken spring) and a blanking plug (pinhole leak). There is a blue-ish deposit in the shower as well which I imagine is copper...

Am trying to find a replacement HF ballast for a fitting believed to be a TLC MDEC 258 [https://www.tlc-direct.co.uk/Products/MDEC258.html]. There are various ballasts for 2 x 58W fittings listed on line from third-party suppliers but they come in several different sizes and fixing centres...

I have a monobloc kitchen sink mixer like this https://www.screwfix.com/p/mono-mixer-kitchen-tap-chrome/5497T (except for the finish). It leaks from the swivel joint. How do I get it apart in order to see what is wrong? TAI Chris

I have bought a replacement quartz sleeve for my Pentek UV-120 steriliser but cannot get the old one out. This video suggests a simple "twist and pull" motion should be sufficient . However it has taken 48 hours for a combination of soapy water and descaler solution to free it to the point...

I have a Bosch SMS4452GB/14 dishwasher which despite its age still performs very well. But recently it has taken longer and longer to fill. Sometimes we need to nudge the programmer to get it to move. I have checked the incoming pressure and the filter in the inlet hose and both are OK...

Woke up yesterday to find house cold and boiler locked out with code 20 (limit thermostat). Reset it and it ran OK for the rest of the day. Flow temp display shows 63C. This morning the same thing happened but the fault code was 79 (flow temp or temp differential too high). Again reset it and...

Hello all, I am hoping someone will be able to identify the manufacturer of this manifold from the picture. The system was installed by the previous owner about 20 years ago and has never worked very well even though I have sorted out several mis-wiring problems. There is a balance issue in...

Have now had a new oil pump fitted to my Archie Kidd VHE boiler and so far so good. However I notice that, after running it for a while with the casing back on, the motor and oil pump are both too hot to touch, is this normal and is it likely to have been the cause of the oil pump failure (shaft...

Because we live at the bottom of the hill and our neighbours have already been flooded with sewage from a blocked public sewer, I plan to install a non-return valve in the foul drain from our house. The NRV will have to go upstream of the last manhole on our property as this is right up...

We have a Kidd VHE boiler with EDGB Inter 2011 burner, Satronic control box and Danfoss BFP21L3 oil pump. This morning the c.h. did not come on and I found the boiler had locked out. On pressing the reset button the motor runs for 14 secs without firing and then locks out again. After...

There is a road drain which discharges into our garden and flows down a bank in a concrete culvert about 9 ins wide x 6 1/2 deep covered with slabs. eventually disappearing underneath the next-door garden in a 6 in earthenware pipe. The overall drop in level is about 2m over a distance of 17...

We have a 2005 Corsa 16v hatchback and in recent weeks have noticed water under the carpet in the offside rear footwell. There does not seem to be any obvious source of a leak e.g. round the door or window seals, and the two blanking plugs in the floor pan beneath the carpet are securely in...

What should I expect to pay for second-hand slates? My neighbour has a quantity of 20 x 10 in slates left over from a dormer conversion which I want to re-use on a new garage roof to match the house. Both properties were re-roofed with new natural Spanish slates in 1993 so there should some...

We are having a dormer loft conversion done, with a flat roof meeting the original ridge line. To begin with, the specialist company told us they would trim the back wings of the old Victorian ridge tiles so they would fit securely and refix them in mortar. I have taken one up to the roof to...
