    What’s this black plastic on new radiator

    Yep - exactly that - just to stop the end panels getting bent out of shape and act as a stand off piece for the brackets as it's a Type 11 and there's no back panel. As suggested, there's usually covers actually over the brackets to stop them getting flattened. They'll do the same job by the...

    Re sealing a bath

    Something like that. Good pointer here - and these guys actually use grout but would be the same process with adhesive I would think Tile Backfill Repair

    Electrical Issue With Central Heating

    OK, definitely - don't leave it like that for long. If there's one thing to get right, it's the main power cabling from the fused connection. At no point should it be using incorrectly coloured wiring to feed the main power into the system, that's just asking for real problems in the future...

    Electrical Issue With Central Heating

    240v @ the neutral for the CH valve? Well, obviously there shouldn't be 240v on the neutral and that wouldn't usually be internal to the head, unless there's a short in there of course. Cant really tell from the photo but I'd be checking back at the wiring centre to start with but be careful...

    Woolwich man jailed for dangerous gas fitting in Croydon

    Yup, when it's a non qualified individual doing gas work then it's an out and out criminal offence. Just unfortunate that it takes something that's unsafe and no doubt obvious, like a gas leak etc for these shysters to be found out.

    adding to shower

    Where are you locating the controller unit, same place as the current I guess? Where is that and how is the supply to the current hand shower wall outlet run? Depending on what the wall is constructed from would determine if you could then run a feed from the controller up inside the wall and...

    Re sealing a bath

    Grout won't change the 'hollow' sound no - if the grout is to be cut out then I have seen tilers use a thin slurry of adhesive syringed/piped in at the back and that fills the void and left to set. Not sure if that would work with these though gravity would be your friend.

    Bleeding a unvented non-combi boiler rads

    Normally only if the rads are cold at the top do the rads need bled. If the rads are cold in other areas around the bottom then that's usually something else. As suggested - bleed key and you'll find loads of step by step tutorials online. The rad vent is opened on the rad until only water...

    Bleeding a unvented non-combi boiler rads

    What makes you think you need to bleed the rads?

    Not Getting Hot Enough!

    Has this only started since the new pump went in? No - the boiler shouldn't be short cycling, with all 12 of the rads (average sizes?) calling for heat then that boiler should happily modulate down to around 7Kw. If it's short cycling then it means the boiler is reaching max set temp and...

    Backfilling around compression fittings?

    Is it to be tiled? backfill that section with adhesive. Cut the tile as close to the pipe as possible and then use the correct tile drills to drill the tile to take a plug. just need to be sure you can miss the fitting. Fitting kit bracket screw holes look a bit tight too.

    Electrical Issue With Central Heating

    If you're happy testing 240V then if there is no power on the pink to the valve (that will be the live brown) then either the programmer isn't sending out a 240v Live call for heat or the stats receiver isn't passing that on to the valve. When the programmer is calling for CH then check for 240V...

    Washing machine waste hose

    As a rule of thumb, I run the drain hose to rise at least as high as the machine, it can then drop back down to the waste its to be connected to.

    Moving kitchen plumbing

    There's going to be a fair bit of groundwork required. An outside section where the services are currently located will need to be dug and the cold water mains and ducting moved and the waste picked up and then re-ducted and re-run to where required. Then the slab will need channelled and the...

    Freestanding bath.

    Hence the question to check there's is a joist in between for all it takes. I would presume there is one but always best to check. Wouldn't be the first time I've seen dodgy floor joist spacing though. Seeing what I've seen in my time, personally I would never assume.

    Silicone after grouting

    Yeah, understand, a bit of a pain for sure but better that than a call back later on with issues.

    Do basin fixing kits work?

    M10 screw bolts should be more than fine. As long as they are into well supported batons then all should be good.

    Cant say I've seen many domestic floors done in OSB, maybe different down south tho

    Freestanding bath.

    I wouldn't think that the joists centres would be 800mm which is what they would be roughly, if the bath width is 750mm and the joist is sitting just outside the edge of it and they are running in line with the bath. So would think there would be another between the one @ the wall and the one on...
