Whole house pump

[Chalked]

Have a customer who has moved into a house. It has a megaflo. Feeding three bathrooms. He is not happy with the flow rate. ( 3.5 bar static but drops to .7 when drawing @17 lpm) someone had fitted a twin impeller pump to one of the showers! All this achieves is to suck the water out of every other tap!

He seems willing to go for best option.there is plenty of space in the garage And even a concrete ledge to fit storage tanks.I would go for a storage tanks ( maybe 200gallon?) a variable speed booster pump and a pressure accumulator tank.

whats best? And where?

ta very much

Proper booster set with staged switching and two or three 200l tanks

I would have thought an accumulator would do the trick on it's own. Don't bother buying an accumulator though, just get a large potable expansion vessel to use as an accumulator. I would be explaining to the customer that resolving the problem is a two stage process. Stage 1 add an accumulator and if that is not sufficient add the pump after. Covers your back then and the customer will be happy that you are thinking of his wallet.
