Hello ChrisR and Corgiman. Right: I've done what you said. I bought a mains pressure test valve. Pressure is 8.5 bar. Then I opened (full on) all the direct-fed taps (of which we have three) and timed flow for one minute, collecting the water in buckets. Flow appears to be 28litres/min -...

I've just cleared an embankment running along the rear boundary of my garden. The embankment rises about 1.5m to a fence which is between us and the adjacent garden. The slope varies, but is mainly 45-50deg, and about 60deg at its steepest. I want to grass this embankment. I would prefer to use...

Duly noted. Thanks for your help and advice, Corgiman.

Define "competency qualification"..... :?:

Err... no, Corgiman. One or other of two local plumbers will do it, but I like to know what's going on. If it requires a 22mm supply, then I can get this sorted in my own time, before the plumber tells me I need to do it before he can commission the system. So, what's a tundish, then??

I appreciate what you say, Corgiman, but to achieve the 22mm objective, it looks like I'm going to have to dig up the main until I find where it connects to the supply company's plastic pipe, and then get it replaced with 22mm............ Mind you, I could then get my own stop cock put in which...

I'm still planning to get a Megaflow system installed (eventually), but I read somewhere that you had to make sure that the incoming water main was of sufficient pressure and flow in order for it to work properly (i.e. provide adequate flow at the taps, etc.) The article suggested that 15mm...

Good point, Hazelb. I'll certainly do this. Thanks.

Djinn, where might I find these legal requirements?

Hello Mistee. I was thinking about your little problem earlier today. When the plumber installed your neighbour's flue, if it is right on the boundary as you say, then he must have accessed your property in order to drill the hole and fit and seal the terminal. So, did he ask your permission...

I have an early 1950s house. It has a central heating system heated by a Baxi back-boiler gas fire. The CH system has been fitted at a later date, but I guess about 25 years ago (when 22mm copper pipe was joined with swaged ends which fitted over the next length). The chimney has been lined to...

No, I didn't, HarrogateGas. This is one of those grey areas where I wasn't sure where to post. If I posted on "Tools" I'm sure someone would say: "Have you tried Plumbing?" (since it is about a specific plumbing tool). I elected for "Plumbing" on the supposition that most of the contributors...

I'm looking for a 'Y' or 'X' shaped key with different sockets on each leg to fit drain cocks, central heating pump valves, and sometimes, rad valves or gate valves when the knob/handle is missing. I can't find anything on Screwfix, and the one I bought from B&Q doesn't fit anything (even though...

Rubbish. They don't take out the old stuff, they just increase the thickness to the current spec (250mm, I think). Quote should therefore be less, as they will need less insulation. Yes, there was insulation in my loft: 100mm stuff. Now, it's 3 times as thick! They're just trying it on. If...

Ask pretty mch any of the larger companies in Yellow pages. They come along and give you a quote. at the time, they will ask if you are on any benefeits, receive WT credits, etc., and adjust their quote accordingly. In the summer, we had our cavity walls filled and extra insulation in the...

Anyone tell me how this device works? I can't find any info on the web. A cross-sectional view would be helpful.

I have a large garage and cellar under my house. In the cellar, you can look up and see the underside of the flooring and all the joists. Great for plumbing and wiring mods, but not so good for insulation. At some point, I may insert insulation material up between the joists, but not until all...

Aaaahhhhhhh.......wash your mouth out :twisted:

I did a test this morning: 3.5 litres of cold water came out of the tap before warm water appeared. Now, say 3.5 litres 3 times a day, times, say, 350 days, = 3.6cu. m/year. Down here in the SW that costs me about £12. Hopefully, when I get round to installing the Megaflow system and re-routing...

In due course, I (or more accurately, a plumber), will be installing a Megaflow hot water system in my house. This will reduce the time it takes for hot water to appear at the taps. Now, this might be a stupid idea, but what's to stop me installing a sort of flow and return loop in 22mm...
