It would seem even stranger to then carry on with 28 mm water pipe after the boiler if the inlet is only 15 mm. Our rising main and stopcock in our old house is 15mm, and we have mains pressure hot and cold systems fed from it. Sorry to revive an old topic - but about to replace my 32mm MDPE to 15mm stopcock (temp set up) to directly feed the 28mm internal pipework.The TALBOT high quality stopcock chamber with a standard base is used for 20-32mm stop valves and has a 700mm tube with a Talbot product code of E3199. 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? Compatible with both commercial and domestic properties, these useful valves are available in a wide range of sizes and materials. Also, if you go to 22mm copper, just use a quarter turn full bore lever valve as an isolator - quick and simple and very rarely do they go stiff. The main difference is that the resistance of pipes goes up with flow rate (so somewhat more similar to an incandescent light bulb than a wire).

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 suppose you still could go straight into a 22mm manifold then off to appliance in 10-15mm if you felt there was some benefit with that setup. say 28kW , so as to create a safe burn , as with all pipework , you get a reduction in pressure relative to friction, resistance . 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?Accordingly, having most of the important info in one thread (a well named thread) is the first priority.

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. will take water from that pipe, so if you have a large cold supply pipe, then the dynamic pressure drop at the combi input will be minimised when you're drawing off cold water to other things (e. PlumbNation is a trading name of Online Home Retail Ltd (company number 03852312) registered in England.Also is there any reason not to then use a check valve and peglar full bore lever valve in place of the brass stop cock? Certainly change your distribution pipework to 22mm if possible, it would be a bit of waste to lose all that nice quiet flow if reduced to 15mm. The Philmac Stopcock 32mm Black Metric/Imperial is a compression fitting made from acetal and polypropylene. Yes, the DHW outlet for a domestic combi boiler will only be 15mm , generally most just T off as you said.

The grip and seal on the pipe increase with pressure and tensile load so that the pipe will burst or neck before the fitting fails. 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. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Why do they manufacture 32mm MDPE without matching brass stopcocks surely 32mm to 28mm internal is a standard setup?Water meters are usually more expensive than 15mm, but you will get the associated flow reduction going to 15mm instead of 22mm.
