The Rainstore Indirect Header Tank Rainwater Harvesting System features a header tank in the loft space that provides water pressure to all appliances and ensuring that pressure is equalised. The wall mounted control panel manages the system and in conjunction with the header tank also controls the rainwater delivery to your appliances. All Rainstore systems feature a heavy duty, low profile, single piece tank, which has an in tank filter fitted to ensures the quality of the stored water into the tank. The filtered rainwater can then be utilised via the intelligent pump which is installed in the tank, which pumps the required harvested rainwater to the header tank. Sizes from 1700 litres to 10,000 litres to choose from.
