Question about Cold Water Booster Set

[rpm]

pressure maybe 1 - 1.5bar but i will have to checked, flow rate no idea

Until you know these this thread is a total waste of time and you may as well stick a wet finger in the air, sorry Mateus but facts are required to help/ guide you.

OK i will measure, according to my research i can buy cap and get the measurement

The weir cup will give you the flow however still need dynamic pressure as well.

5. budget i don't know i would like to buy something right quality to money and install my self. I know how to hold spanners and pliers.

You do know of course that the installation of a booster pump drawing more than 12L/M is notifiable to your local Water Undertaker under the Water (supply & fittings) Regulations 1999?
You must give formal notice in writing before you start, it is likely that they will wish to inspect the installation upon completed.

Hi Chris
Last time I rang the local council to notify. They put me through to building control, who said
“ don’t know what your on about?”

Chris that is only when the pump is directly connected/ fed from mains not when your feeding from a stored source

This is the Water Regs Chalked not the Building Regs so it falls to the Undertaker to administer & enforce.

Sorry Shaun but it isn't limited to directly connected pumps.
It makes it quite clear that it applies to pumps that are indirectly connected drawing more than 0.2Litres/second. see - Table 5 (1), sub-clause 4(d) and it provides a diagram R6.1b showing indirect connection break cistern.

But it’s not drawing from the main it’s being fed from a tank

Why would they need to know you’ve connected a pump to a tank don’t have to let them know about shower pumps

Full guidance is given in R6.1 but to answer your question installing a pump even if it is indirectly connected will increase the draw from that supply main (more water out = more water in) especially if the cistern is not sized correctly therefore they want to know about a risk that the main pressure could drop, leading to an increase risk of back siphonage in surrounding properties.
Them's the rules "you have to give notice before you start" They then have 10 working days to respond.

At the end of the day, increased usage by one property in a stress water supply area wether its pumps that suck, or push on stored water leads to the neighbours getting kicked they all install one and everbody is back to square one. Did one in Hightown a few years ago, Grunfos one, guess what we more or less worked our way round thus little cul de sac. and they are all back in same desert Happy Days Rob Foster aka centralheatking
