Pumping Mains

[DaleRCL]

Morning Guys,

A builder I work for has put me on to someone who has recently had their house refurbished, new plumbing etc. The plumber fitted a Megaflo without checking the incoming mains pressure (just over 1 bar) and subsequently there is not sufficient pressure to outlets.

The customer has nowhere to install a break tank and has asked me to fit a pump on the incoming mains. I have googled to see if this is do-able and have had all sorts of conflicting reports on the legalities or even the feasibility of doing it.

Can anyone tell me if it is legal, and if it is, reccommend a product I could use to pump it.

Thanks

Not legal to install a pump straight off the mains.
Since a megaflow was installed I assume there must have
been a cold mains header tank previously.
So it is a case of installing/reconnecting this and feed
the megaflow off this as if it was a conventional hot water tank.
Alternatively you can pump from the cold header tank into the megaflow
to build up pressure.

From The Water Supply (Water Fittings) Regulations 1999 you cannot fit a pump or booster drawing more than 12 litres per minute unless you have permission from the supplier.

There is nowhere to site a break tank so pumping from storage tank into Megaflo isnt an option

Doesn't an accumulator just improve the flow rate when multiple outlets are open, not the pressure?

You need a Mainsboost accumulator and Charger pressurisation unit. (No accumulator will work properly on 1 bar static; the make is immaterial - the engineering fundamentals are identical).

The Charger is approved for direct connection. Expensive and brilliant. We've fitted a fair number.
