Booster pump recommendation

[David9546]

Hi we built our home and plumber installed a jojo 1.1kw booster pump i see pressure is not great and I see its stuck on 3bar. I see from tank to house is about 13 meters with 40mm pipe then it reduces to a 22mm copper. It the goes up 7 meters double story house has 3 bathrooms i see if I fill a bucket that it is 14lt per minute

That flow rate is about average. Not great but not bad either.

Check the pressure on all the taps. If it's better on some than the others, the issue is probably with the faucet/showerhead itself...

Hi i measured all the taps further away is a bit less 11-12 l per minute and closest is 14
