I have a Polypipe wet UFH system which heats a large new extension (5 circuits off manifold) and an old study where the floor was relaid (2 circuits off manifold) with 100mm of insulation over concrete and under the screed. It works well in the extension, but will not heat the study. The...

We have a polypipe wet ufh system with PBPRP controller which works reasonably well, over a period of time learning how early it needs to call for heat in order to reach the comfort temp through the ITCS feature. The problem comes when we light a wood burner in the room. Despite following...

We have a pump on our hot water system to deliver hot water immediately with no delay (long pipe runs). Currently it works off the timer when the water is heating. While altering the kitchen I want to wire it so that there is a switch (plus neon) in the kitchen to put it on while washing up...

I have several wooden Little Nipper mouse traps which were used successfully last winter. Having got them out again I find that the springs are suddenly weakened so that they won't set, although they were fine when put away. I appreciate they only cost a quid or so, and am happy to replace if...

We have wet u/f heating in a new extension, with Polypipe PBPRP programmable room thermostats. Apart from the fact these are a nightmare to programme, I wondered if anyone had any thoughts on the most efficient way to set them? We want warmth morning and evening: the Optimum Start feature...

I have a ball valve fitted to an expansion vessel on a cold water system - usual pressure is about 4 bar. Despite several attempts using ever more PTFE and or Jet Blue, it continues to weep at the thread. Can anyone suggest a remedy - should I stick to loads of one, a combination, or what...

I have a 25mm MDPE pipe entering house from rainwater harvesting system. I need to put an elbow on it, then run into a filter with 1" BSP taper threads (female) and from there to a control unit with 1" BSP fittings. Question is, what fittings and pipe can I use internally? Plastic MDPE...

Just opened door of Zanussi jet stream washer dryer after a wash (not dried) to find everything covered in a pale grey dust which looks suspiciously like disintegrated door rubber. There is loads of it, much stuck in the creases of the seal. But the seal itself looks in pretty good condition...

I am building a single storey lean to type extension and want to put a wood burner in it with a twin wall s/s flue but am having extreme difficulty making sense of the building regs concerning this. They seem to indicate that as long as it is over 2.3m from the neighbouring buildings it needs...

I am putting in a woodburner in an existing fireplace which I have opened up back to the original brick opening. The constructional hearth is soft brick bedded in sand/weak mortar, and is very damp, and I am going to replace this with concrete. It is an old house (1800) with no DPC, and I...

Just replaced my top fitting immersion thermostat as old one had failed - see earlier post - thanks for the help b****r of a job, but got it done. There is now a slow but steady leak from round where the thermostat fits into the element. There doesn't seem to be any washer/o ring/seal etc...

Immersion thermostat seems to have failed - tank boiling water up. Purchased a new thermostat (for top fitting single element immersion), removed wiring and loosened old thermostat. Then the problem... Immersion tank is raised off ground, and too near cold water cistern above it to be able...

I have moved into a house with a Gardtec 800 Series alarm with LCD keypad. I need to decommission it while I carry out some major renovations. I have the user and engineers codes - can anyone tell me how to do it without having to disconnect everything please? Thanks

I have been looking into installing a rw harvesting system for toilets, washer and garden watering, but as the garden rises away from the house would have to bury the tank very low to get a fall on the pipes. Last night I dug a test hole, and hit the water table 1300mm down (sand and gravel)...

I'm looking for a value for money core drill plus bits - for occasional use drilling waste pipes etc up to about 127mm through brick and stone. Anyone any experience? Thanks

I have a fully pumped gas CH system with Horstmann Centaur Plus C27 programmer and Honeywell V43073A1088 motorised valve. When HW or CH are on separately each work fine, and motorised valve (with cover off) can be observed moving from one side to the other accordingly as Boost/Advance are...

Trying to connect new chrome effect 15mm pipe to new cistern. Bought a C x Fi coupling 15mm x 1/2"(42832-92) from Screwfix as this seemed to be only chrome fitting available but, unlike a conventional tap connector it doesn't have a spigot inside it. Will this connect to the plastic male...

Just bought moretti mono basin mixer from screwfix... and opened it up to discover it is recommended min 0.5 bar. I have mains cold supply and gravity hot supply with approx 0.3 bar. Does anyone have any experience of whether it will work satisfactorily, or should I try again?
