Hi all, Not sure if this should be in electrical or one of the other forums but sure the problem is encountered a lot more here! Have also tried searching and can't find the answer. Just wondering what the correct method is for protecting cables penetrating a 30 minute fire ceiling? I can...

Hi all, Final step in our renovations is to sort out the insulation in a timber frame 'overhang' section of my daughters bedroom. The rest of the house is brick and overall this section is relatively small. The make up appears to be the timber frame with c.50mm of fibreglass insulation...

Hi all, Can anyone please suggest solution to adding two small (c.18 and c.12m) loops to an existing heating setup that consists, in short, of: UFH throughout downstairs, split across 2 manifolds each with a mixer and pump set but no temperature control other than mixer and flow rate Large K2...

Morning all, Does anyone have any advice on how to do silicone sealant neatly when one surface to be sealed has a wood grain? In this case it’s a white tile splashback to solid wood worktop with white sealant. When I smooth it off the sealant ‘bleeds’ into the grain slightly and I’ve been using...

Hi all, We’re planning to have a drive redone and as part of the works planning to have a couple of large tanks to divert surface water to as we live in a high risk environment. New soakaway for on catchment surface water will be sized and located as per regs but I can’t find anything anywhere...

Hi all, Feels most relevant in the ‘Building’ section. Is there such a thing as expanding silicone sealant, or a.n.other waterproof sealant? Basically waterproof properties of silicone with gap filling of foam? We live in a flood resistant property and need to make a soil pipe penetration...

Hi all, We have an extension that at some point we would ideally take a water feed to - due to a number of factors, going through the house is not possible. We have our mains water pipe in the drive that we could connect to. My understanding is that any mains water feed has to be buried at a...

Hi all, Having a challenge interpreting Part J of building regs, specifically distance from log burner to combustible materials; in this case an oak mantel we are about to install. Our Stovax Stockton 5 stove just lists ‘N/A’ as distance required above the stove. My (perhaps incorrect)...

Good morning experts, Just looking for some advice to help with some post flood renovations that we are doing. We are creating a new ensuite in an existing garage conversion that has a bedroom above. Structure isn't changing, just gutted it because of an abysmal (but bc signed off) insulation...

Good morning all, We're currently working through knocking around an existing bedroom above a garage. This includes a new staircase, the existing of which took up a huge amount of space - so we're trying to rationalise and create as much floor space as possible. Our architect, who...

Morning all, Hopefully a simple question! Is there any reason why I can't fit a rectangular shower tray with the waste at the 'opposite' end to 'usual'? Basically at the walk in end rather than under the shower itself. Would make the slotting of waste pipe into a gypsum screed much, much...

Hi all, I have previously asked about possible ways of running 2x 28mm Flow/Return and 2x 22mm Cold/Hot to a remote annex. I can't find that thread now so apologies for asking another one but this might be useful for others searching in future. So this may be a very stupid question but here...

Good morning team, Not sure if this question sits in woodwork/carpentry or flooring but here goes! Just had a DIY-Kitchens delivered (Linwood range in Carbon, absolutely fantastic quality for anyone thinking of one) and need to make a start on getting it fitted. The fitting will be taking...

Hi all, Is there any reason, regulation or otherwise (aside from best practice) why pipes cannot be run within the cavity wall? I need to get 2x 28mm (CH F/R) and 2x 22mm (H/C) to a remote part of the house and currently have a large section of the cavity exposed due to having to replace flood...

Evening all, We’ve got a relatively thin 30-40mm Calcium Sulphate based liquid screed (Gyvlon Thermio+) set on top of PIR insulation. We need to channel the screed to lay some new pipe work for an extension (2x 28mm F+R pipes, 2x 22mm cold+hot pipes) and just wondering if anyone could advise...

Hi all, I’m looking for conduit for 28mm plastic pipe and conduit but not having much luck. Any suggestions for both pipe and conduit brand to look for? JG Speedfit do the 22mm pipe and conduit; 28mm pipe but no 28mm conduit! I need to run a 28mm flow and return that will be buried in...

Afternoon everyone, I'm just preparing our existing, uninsulated (we think) floor slab for imminent installation of underfloor heating (booked for c.2 weeks time). Short version: I'm an idiot and didn't consider everything. Long version: We are limited in options for height build up due to...

Good morning all, Just starting preparations for existing slab to have PIR insulation laid over the top before UFH and liquid screed. The top layer of the existing slab is quite rough and won't provide a decent base for the PIR to sit on so I think I probably need to provide a blinding sand...

Hi all, Do any of the fall type requirements for an SVP apply above the last branch/connection connected to it? Can't find anything online anywhere. Basically planning a new SVP and want to take the venting part of it as far across the side of the house as we can to prevent shading on solar...

Good morning knowledgeable ones, Could anyone possibly point me to the written regulations regarding how much cover a domestic gas pipe must have when buried in concrete screed? I should be clear that I am not trying to work out what I can achieve, but rather make the case that a gas pipe...
