storage tank?

[Laburnum]

The water pressure in my pub is really poor. One example is if two toilets are flushed they seem to take forever to fill.

I have chased it up with the water co for months now, but no joy of any improvement.

An idea we had was to put a storge tank in the loft and soley just feed the toilets in the building,

Would it be advisable to use 22mm pipe to increase flow rate? and can you get ball valves that are designed for low pressure? ( the highest we can get the tank is roughly about 3m aboove the highest cistern)

Any advise and suggestions will be deeply apresiated.

Thank you in advance.

All new ball valves usually come with both high and low pressure inserts. Low is for tank fed cisterns. The more height the better. have you actually had the mains pressure checked in the street? it couldn't be a blockage or half jammed stop cock in your water inlet pipe?
