Cold water header tank in workshop Drainage and wastage systems and plumbing help, advice and answers

[wadeydiyer]

Hi,
I have a workshop that was built over 30 years ago with original washbasin/pedestal and close coupled (plastic cistern ) toilet. Only cold water as hot water is fed by a small electric water heater.
Rising main comes into property and goes to one cold tap then continues to a header tank above the cloakroom which then feed a cold tap in the same sink and the toilet cold water feed.....
Looking to replace with the infamous 'Sink in a box' and 'Toilet in a box' from the good ol' boys at City Plumbing. Can I do away with the header tank/ballcock system and, more importantly, why was it there!!

Hi wadeydiyer,
Best suggestion is that when built the water supply was not reliable so a tank was added so there was always water available. If you have consistent pressure and flow you can take the tank fed part out of your system.
