Hi there. Our family have a number of showers in the morning, and I'm finding that after a 20 minute run of our shower (Aqualisa Quartz Digital), when we restart the shower for the next cycle, it starts fine, then runs super cold for a minute or more before re-stabilising. I guess that means...

I'm looking for a replacement part for my aqualisa shower but aqualisa will only sell me a complete processor unit. The part I'm looking for is inside the intake valves. It's the actuator "spider" which goes between the motor and the valve plate. I assume all quartz digital models (old &new...

Hi all, Just had my building inspector round this morning to check my extension against the completion certificate. He found a couple of minor issues, but potentially the most major one is that my joiner has built the roof with 225 timber at 600 centers instead of 250 timber at 400 centers...

I am installing a new downstairs WC and am wondering if I need a vent stack, or stink pipe, if ALL that I have on the drain is the toilet. The sink is drained separately as it would have been awkward to tie it into the toilet waste. There is a bedroom above the WC, so no additional...

I've run conduit through my garage for mains and lighting (on different circuits) but am struggling to get the T&E through the conduit (1 x 1.5 + 1 x 2.5 pretty much maxes the conduit out). As such, I think I'll need to switch to using singles instead of T&E. Screwfix sells conduit cable...

We have just broken through from our house to our new extension, and found that there is a discrepancy of approx 100mm in the position of a wall! Ouch! Anyway, that would mean that as you arrive on the top step of our existing stairs, there is only 800mm in front of you before the bathroom...

Sorry for posting these curious questions, but I'm... well... curious ;) My combi boiler is fitted in my loft, well above all rads in the house. Is it possible that air in the system could gather in the boiler, or in the pipework nearby, rather than in the rads downstairs? If so, is it...

Obviously to prove that a system doesn't leak. I'm pretty sure my plumber did NOT pressure test my plastic pipe CH system when he commissioned it last night. I'm just curious as to whether the 10 bar pressure ONLY tests for leaks, or actually has some "setting" action on the fittings -...

I'm looking to put down a durable smooth surface for my one-and-a-half car garage which we've just finished building. Seems there are plenty of places in the States which sell "commercial grade" epoxy flooring materials, but I'm looking for somewhere in the UK. Does anyone know where I can...

Just finished extension including wiring all tied back to new CU inside garage. Wiring has all been inspected by registered electrician and he is happy. (okay I'm only at first fix stage so far but getting there and he is happy so far). Electrician told me to use 10mm2 t&e to supply the new...

We have just finished building an extension to the side of our house, and with all the heavy machinery which has been onsite in the last six months, our slabbed driveway has turned into crazy paving with at least half of the 2ftx2ft slabs cracked and now about as level as a scottish hillside...

Building a new extension and am planning to run CH pipework myself if possible. At present, it seems like both upstairs and downstairs is on 10mm pipe, splitting off from 22mm pipe from boiler, under the house. I'll be putting 2 more rads upstairs and 2 more downstairs, but am guessing I...

I need to run a 50mm length of 1st floor bathroom waste pipe across my extension ground floor ceiling (6m) then down the wall, before going through the wall and into the main drain. There is no vertical 110mm waste pipe (soil stack) in the vicinity to tie into. The attached picture shows the...

Can I substitute two 6mm2 t&e cables in place of a single 10mm2 t&e cable? I need to run approx 4-5m from my old CU to a new CU in my extension, and the electrician has specified 10mm2. That's fair enough, but I have half a drum of 6mm2 cable in my shed, and although I understand that the...

My builder has just laid a new garage floor, and for all intents and purposes it's fine, but it's just that he has floated it by hand. Although it would be fine for storing my car in, I like to use my garage as a photo studio, and also as a workshop to restore my classic car. The rough...

I rebuilt my 1st floor bathroom about three years ago, swapping the location of the bath and the sink, and lowering the bath down to rest directly on the joists (strengthened). At the time, I used all 40mm push-fit waste pipe from B&Q, which went together fine. Draining from the sink, the...

I want to replace my CU and backboard for my house to have it better laid out, remove redundant equipment and make adding new circuits easier etc. I have Scottish Gas coming round next week to install an isolator switch making replacement of the CU safer, but as the meter and bullet fuse are...

I'm installing new soffits & fascias from scratch to an extension we are doing just now, and am wondering if there is a particular way they are normally constructed. Soffit depth would be approx 200mm. Intention is to have 6x2 rafter ends cut vertically then a 25x200mm softwood fascia nailed...

Moved to roofing / guttering.

New extension. Rafters have been terminated onto top of timber frame but stop short of outer block skin. It seems an extra course of blocks has been laid to make up the difference. Of course, now the sarking stops short of the top course of blocks and slater is upset as he has nothing to...
