I think, Shevek, that it would be more useful for all if your threads were more generic and that in future I will be quicker to start another, more specific, thread, if the generic one has drifted or lost interest. So I have a 24kW combi, with a 22mm supply pipe from the road (length 10 metres or so), until up close to the boiler. I've kind of got a bee in my bonnet now (thanks to you guys :p) about doing what I can to reduce pressure/flow variations when multiple outlets are open - it's one real bugbear in my current wee flat - the minute one thing comes on (like the washing machine), the hot water taps or shower immediately drop in pressure. These two books are the perfect starting place to help you get to grips with one of the most vitally important aspects of our society - our homes and living environment.FloPlast's WRAS approved MDPE Systems are suitable for use below ground on cold water services with polyethylene pipes manufactured in accordance with the requirements of BS EN 12201 - 2 (BLUE). Accordingly, having most of the important info in one thread (a well named thread) is the first priority. If underground it may be cheaper to first reduce the 32mm MDPE to 25mm and then insert the necessary stop cock and tee off all in 25mm. Can I assume you've read here and on EB about taking the outside tap off either outside as a tee off the 32mm mains incomer, or immediately after the stopcock eg before the PRedV?

I think I may be being a bit thick, but our incoming supply is 32mm, which I'm going to run right up to the plant room and tee off to the UVC and to the cold water manifold and fit a reducer to each. It is worth running large pipes to supply the combi with cold water, since that doesn't contribute to wasted hot water, and also other things such as the kitchen cold tap, toilets etc. The main downside with having a 15mm cold main going up into the loft and right down to the other end of the house from where it comes in is that it's a bit noisy. They do get a little sneaky - especially one of the utility contractors - and fir 32-25 reducers, then a 25mm water meter, then back up to 32 to the house.Most combis have 15mm pipework for DHW, because at the flow rates they support (they have a flow rate limited built-in usually something like 8 to 13 litres per minute - depending on size), the pipe losses for 15mm copper are usually negligible (and as has already been said, smaller pipes between the hot water source and the points of demand gives less wasted hot water). TerryE - When the plumber (that was too expensive) was on site, he had a look at the incoming 32mm and said he'd just run that right up to the plant room - seems logical to me as it helps with a greater flow rate if I run 32mm as close to the inlets as possible? If noise issue materialise, then presumably I can do something to reduce the flow to the supply anyway? Was he aware you were using a main pressure DHW combi , I presume he was referring to pipe sizing for a gravity fed/main presuure HW tank of similar. I was after a brass compression stop tap for the above, however they don't seem to exist, I read somewhere that stopcock reducers exist but cannot find one for a 32mm tap to 28mm copper does anyone know if they exist if not what about a 28mm to 1 1/4" female iron?

It does seem a little strange to go all the way to the boiler in 28mm (or 22mm) only to reduce it on the boiler input to 15mm. Yes, the DHW outlet for a domestic combi boiler will only be 15mm , generally most just T off as you said. It's a balance; from experience I know when I hit a subject with an all encompassing thread I often lose half of what I'm after, potential commentators switch off and I start being very military again with numbered lists and unfriendly looking re-direction.

I think we'll then change to copper (not sure what size yet, probably determined by what kind of meter and softener we can get), then a drain off valve, then the meter. Given that we're planning to run two showers off a combi I guess we should probably reduce to 28 mm instead of 22 mm, run that to the 1st floor bathroom and then reduce to 22 mm for the en suite on 2nd floor?

I dont know if you can substitute a check valve, and a full bore, for a stop tap - we've never done it, and i've never seen this arrangement on site.Compatible with both commercial and domestic properties, these useful valves are available in a wide range of sizes and materials.
