Hi All, Hoping you can offer some advice! I'm laying a concrete pad (roughly 3.5m x 2.5m x 150mm/6"). Trouble is, I want coloured concrete (a dark gray heading towards a light black) with exposed aggregate. So what I was going to do was get a coloured ready mix in, lay it and tamp it level...

Morning All! Cold start in East Anglia this morning.. woke up to the central heating not working. It's been a bit flaky this last couple of weeks. Boiler is firing and hot (oil boiler. Not combi), central heating pump is spinning away (brand new), water pressure is showing 2bar, the feed pipe...

Hi all, Have noticed that my joists are not exactly 600mm apart, some are 570mm some are 610mm. When I am laying insulation in the larger ones, I am noticing a slight gap. Is this going to be a problem? This problem is worsened by my inability to cut the rolls exactly straight!!! I have...

Hi all, I've run S/FTP pure-copper CAT6a throughout the house for CCTV and wasn't sure how to maintain the interference shield that's inside the cable. There is a multi-strand earth cable underneath the outer insulation of the cable, I can connect one side of this to the house earth, where...

Hello all, It's coming to the time of year again when the mrs is going to want the heating going 24/7 and at 30 degrees (joking!). I've got to drain down the system to fit a new PRV on the boiler and top up with some rust inhibitor. I've always had problems with air locks in this system when...

Hi All I'm no boiler engineer but I am mechanically and electronically minded so I'm hoping you can help me troubleshoot the problem as I have had an 'engineer' come out to look at it and he pointed to the fire stop valve being the problem which I am confident it is not!... Red lockout...

Hi All Have a Mira Excel thermostatic valve installed in both bathrooms, been there for about 5 years or so. They are both fed off a Heatre Sadia MegaFlo. For some reason one of the valves has stopped working properly.... I switch the valve on and the shower is at full flow/pressure...

Hi All I have read various 'how to' guides on tiling and have gotten the idea of what I need to do but I have one or two questions I am hoping you can help with. 1. When marking out the tiles on the walls, should I do it on a wall with nothing on it or on the bath wall? I am asking...

Hi All Yet another question from me.... Ordered a shower fitting which arrived yesterday. I can't see how this would fix to the wall? It's a regular 1/2" tap fitting on the end but the collar (which still has the protective blue wrapper on it in the picture) doesn't act as a stop against...

Hi All I've got one of these fancy glass basin thingys, looks nice. They supplied a click-clack push button waste with it. Ordered a 32mm antivac bottle trap for it from Screwfix but it seems like the threads are different. It will start to screw up to the waste on the bottom of the...

Hi All I'm always draining down my central heating system and refilling after fitting new rads here and there. It's always been a b*gger to get rid of the airlocks on this system so I'm kind of used to it. This time I have been trying to get rid of an airlock for the past 2 days! It just...

Hi All I have bought a back-to-the-wall toilet and cistern. I've been told by the seller that using a flexible pan connector will make the installation easier. I'm reading in a few places that these flexible connectors are prone to leaking (going off the comments on the Screwfix website)...

Hi All I have a thermostatic mixer with female 3/4" inlets and outlets on it. I can find the male 3/4" push fit flexible fittings on Screwfix but not the female ones or any female to male adapters. Am I missing these somewhere? Anyone know what to do? Thanks

Hi Guys Not sure if it matters which I use but want to make sure... I have a Heatre Saudia 'Megaflo' which applies cold mains pressure to the hot water tank to ensure I have mains pressure hot water throughout the house. I'm fitting a new bath, sink and toilet and wanted to know if it's...

Hi all I am asking questions like there is no tomorrow :lol: sorry about that! Lockshield valves. I have found a guide on the web that says to balance them you need to: 1. Open the lockshields and TRV's on all the rads. 2. Switch the heating system on. 3. Find the rad that heats...

Hi All I have purchased some designer wall mounted rads, the kind that go up the wall. They are 1800 x 420 in size. I have mounted them where I want them and plan to chase the pipes into the wall to give a nice neat finish. The question is this: If I chase these pipes into the wall...

Hi All Hope you can help, I currently have 2 standard radiators, 600 x 600 2990 BTU output each, with lockshield and thermostatic valves on each. Being a typical starry eyed DIY'r I would very much like to ditch this in favour of fitting a pair of designer radiators. I have done this...

Hi All I am really getting frustrated with this so hoping one of you guys might have a good tip on how to do this. I have concrete subfloors, I have chased a line which is 3.5cm wide x 360cm long x 6cm in depth. Using the chaser and SDS hammer to punch out the concrete has left me with a...

Hi All Sorry if this is a dead obvious answer but I am having a few probs. Have installed soil/vent pipe on the side of the house which is 110mm diameter. The drain hatch I am trying to connect to has a pipe coming off it which is smaller than 110mm. I know this because I bought a...

Hi All I have just finished my mechanical inspection pit in the garage and managed to get it all fully waterproofed and warm using fibreglass. I read a lot of information posted by a lot of people all over the web who complained that digging the hole and finishng it nicely was not the...
