When you turn on the hot water tap, nothing comes out until the hot water reaches the tap.
The cold (dead) water is pushed by mains pressure to a holding tank in the ceiling.
The water in the holding tank is then used to operate all toilets in the house by gravity feed. No power is used in the supply of water to the toilet.
The holding tank is fitted with an overflow to a rainwater tank for use in the garden. The holding tank is also fitted with an emergency back-up from mains pressure.
With our complete system you have no wastage of water. In most cases you will never have to use potable water in the toilet again.
