Posted By: Shevek Posted By: borpinI went from 32mm to 22 but wish I had gone to 28mm before splitting to H&C of 22mm. Shower Enclosures Wet Rooms Shower Doors Shower Cabins Quadrant Shower Enclosures Offset Quadrant Shower Enclosures Walk-In Shower Enclosures Pentangle Shower Enclosures 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? 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.

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. 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.

FloPlast's manufactures a comprehensive range of polyethylene pipes and fittings for use in potable and non-potable applications.This is the problem with having lots of different threads on closely related subjects: I'm fairly sure Shevek said something about his lot wanting their own meter for monitoring purposes separate from the water company's one but maybe it was somebody else and I, for one, can't be bothered to search. 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. but this is common .I presume this last restriction is not considered to have that much effect as long as the main run is sized correctly It is possible to have one thread that cover just about everything, there are a few on here, the M one and the W ones spring to mind Sorry, after the original post, I've moved this to the "Plumbing: how to calculate appropriate sized pipes for dead legs" thread, where its more directly relevant...

If noise issue materialise, then presumably I can do something to reduce the flow to the supply anyway? Or is it probably six and half a dozen? 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. 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.g. if someone flushes the toilet, you don't want the DHW flow rate to suddenly drop). I haven't done calcs yet but Barney mentions the possibility of running 28 mm from the HWS generator to first floor and then on in 22 mm to the second floor (we're running two showers off the boiler): It would seem even stranger to then carry on with 28 mm water pipe after the boiler if the inlet is only 15 mm.

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. Pipes from the combi to points of use are mainly in 10mm PEX or 10mm copper. dynamic pressure ~ voltage at non-zero current (i.e. under the effects of "upstream" supply resistance). The boiler requires a minimum gas pressure at the gas valve inlet to satisfy the boiler when its on full power jamiehamy was there a reason for using a 32 mm MDPE supply instead of 25mm? Broadly the 25 MDPE pipe has the same internal diameter as 22 copper, and 32 MDPE as 28 copper. You aren't really supposed to expose MDPE to direct sunlight, so you'd normally go from MDPE to copper on entering the house.

So, question is, why would you do that if boiler inlet/outlet is smaller.
