32mm MDPE Supply Pipe upgrade for flow.

[cockneydave]

Hello all,

Currently suffering from poor internal flow rates near the internal 20mm stopcock of 10L/min.

Want to upgrade system to either unvented cylinder or large storage combi to feed 5 bedrooms/1 bathroom/1en suite.

Affinity water have confirmed supply pipe to the boundary stopcock is 25mm mdpe as part of the lead replacement scheme.

House was extended 20 years ago and 20mm MDPE going into the existing stopcock which goes into 15mm/22mm copper around the house.

It is possible we still have a lead supply pipe and was extended to the new stopcock position in 20mm mdpe but unsure.

Flow Rates:

Boundary

40L/min

2Bar static


Garden Tap

2 Bar static

15L/Min

Kitchen Tap (next to 20mm stopcock)

2 Bar Static 10L/Min

My question is would upgrading the existing 15mm/20mm supply pipe to 32mm MDPE help increase the flow (considering boundary is 40L/min)??

Cheers,

Dave

Yes will increase volume but not pressure.
