How to find a slow leak?
Nickfromwales replied to Fallingditch's topic in Central Heating (Radiators)
I think the mention of power flushing as a routine part of a new installation, and power flushing as a resolve to a blocked pipe need separating out. Paying someone to PF dry pipes won't do a thing so would, afaic, be a waste of money, time and effort. When retrofitting a new boiler to old pipes and worse, old rads, a PF is mandatory in most cases. Bump : Are the rad valves ALL new?- 76 replies

How to find a slow leak?
Nickfromwales replied to Fallingditch's topic in Central Heating (Radiators)
I only ask about the filter as it's a 5 min job to dose with Sentinel with one of those ? Eliminate the PRV and come back to us re the leak sealer .- 76 replies

I'm all makita for everything except my chopsaw. I bought the Dewalt DWS 780xps shadow line and it's been a beast. I'd instantly recommend a Dewalt unit but you've got to love this makita one for the price and 12" blade. Im putting that in my wish list. Time to sell the other kidney ?

How to find a slow leak?
Nickfromwales replied to Fallingditch's topic in Central Heating (Radiators)
If the pipes are dry then they're disconnected. There's no way a blockage would be tight to 1 bar on BOTH pipes It may well be that this was the old heat leak rad that was plumbed in parallel to the hot water cylinder so, worst case, will need to be teed back into the flow and return. Is there a magnetic filter at the new boiler location? Oh, and don't forget to make sure rain can't fill the clear bag- 76 replies

There's a general 'rule' down my neck of the woods. If at least 1 in 10 properties in a terraced run ( or run of properties known to share a sewer ) have a vent to atmosphere then they'll give you the ok to not vent and use AAV's. If your end of run then I'd endeavour to vent it TBH, only retro capping it if the stench ever becomes evident.

Cutting existing 110mm stack thats tight to the corner?
Nickfromwales replied to Barney12's topic in Waste & Sewerage
Remember to use a 127mm core not the smaller one for the actual soil pipe as the knuckle of the tee won't go into the recess left by the smaller size core. . Saves you having to chip it out from inside and out. Remember that for a clip to go onto a standard soil pipe run externally, the knuckle of the fitting outside ( if you are having a fitting directly outside of course ) will need to be recessed slightly into the wall too. Mock up a piece of pipe in 2 clips and hold it against the wall, measure the distance and compare it to the fitting, and you'll see what I mean. -
Can't go wrong. Pampers and site boots. That an early shot of you @Declan52 ?

Bath Surround / Boxing In, and concealed pipework
Nickfromwales replied to Onoff's topic in Bathrooms, Ensuites & Wetrooms
Good idea. Silicone is the anti-Christ when your looking to glue or paint something. I worked in an autobody repair shop for 2 years, prepping and priming damaged cars. I also got given the splenderific task of sanding out and machine polishing ( mopping ) any evidence of 'fish eyes' ( where silicone had somehow got into the booth from the valeting bay next door and caused the paint to react / not adhere properly ) which was a soul destroying job on a good day. Even worse when it's outside. Oh and don't keep the mop still on a freshly painted, plastic, Rover 216 door handle either Oops. Another day I was working for free -
Bath Surround / Boxing In, and concealed pipework
Nickfromwales replied to Onoff's topic in Bathrooms, Ensuites & Wetrooms
Yup, but only M-S if there's any excess crap to remove, like old silicone etc . If it's a relatively clean pipe then Meths will do the job on its own. -
Only advice to add to this phase is to add one or two automatic air vents ( bottle vents ) instead of the manual ones. Will make commissioning a much easier job . These will screw straight into the empty holes ?

I did an entire oil boiler job once in around 400mm and less crawl space. Fitted all the central heating rads, pipes down into the 'basement', then under I went to extend, clip, and insulate it all from 10mm to 15mm to 22mm. And a poxy favour job Just resign yourself and crawl around until you love it. Then start working. Enjoy ?

100m2 is not quite so limited . Also, , for large installs you simply run multiple ring mains accordingly How many rewires have you done in a medium sized house that have a ring for the kitchen / utility sockets, a ring for upstairs sockets, and a ring for downstairs sockets? More than one? ( I know I'm going to regret asking, but I'll take what's coming )

Unvented Cylinder D2 discharge pipe calculations
Nickfromwales replied to ProDave's topic in General Plumbing
22mm will be ample if there's no immediate invert. They're what cause the problems. ? -
Just have a joint in the pipe . Maybe fit one of these where the joint is going and use this as your connection point for the basin and utility etc . Use metal brackets for the horizontal run, one just before the break, and another two on the remaining run before it goes vertical to the new loo, ( as plastic ones are a bit shite on horizontals as only one side of the clip really gets strained ). I often find these broken over time with the run all shapes. .

Nickfromwales replied to ProDave's topic in General Plumbing
How much vertical fall can you get from start of D2 to first invert ( to horizontal ), and then how much horizontal before the next drop Dave?
