32mm MDPE DZR Stopcock

Product Information

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).

Using a common body and only two sets of interchangeable components, Talbot Pushfit will connect to metric PE pipes and their imperial equivalents It would seem even stranger to then carry on with 28 mm water pipe after the boiler if the inlet is only 15 mm.

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?

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.Yes, the DHW outlet for a domestic combi boiler will only be 15mm , generally most just T off as you said. 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. re. water supply , not sure why you'd need 28mm but makes sense not to starve/reduce potential flow to the combi DHW cold feed as djh says , to other take offs . so using a larger bore up to boiler would priorities the DHW cold feed. On domestic jobs I general do it in 22mm up to combi boiler. No, but why give yourself extra work by reducing before the stop-tap? Some utilities want the service MDPE to go in one length from stop tap to stop tap.

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 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):Shower Trays Rectangular Shower Trays Square Shower Trays Quadrant Shower Trays Offset Shower Trays Wet Room Shower Trays Pentangle Shower Trays Shower Tray Accessories 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.
