Hi, Andy.

Unfortunately, I have already replaced the service pipe with a new 32mm
diameter pipe. Cambridge Water tell me that they can't do anything about the
flow/pressure "because the supply is fed directly from a reservoir".


This rather suggests that their main is limited.

You cannot be seriosu.

Any main that feeds more than a couple of houses will be large enough to
feed one at high volume.

I was really referring to the statement from the supplier.

If the flow is being measured at the end of the 32mm service pipe, the
pressure was 2.8 bar and the flow only 25lpm, it suggests that
something else is wrong.



I think I am at about 3 bar hgere and water simply gushes out.

My main restriction is internal pipework and the water softener.


The best thing that you can do is to look at all the components after
the service pipe. e.g. stop cock full bore lever ball valve, 22mm
pipe internally to key points or 28mm for anything of any length,
avoid too many bends.


Totally agree here.
