With the system which uses mains water to top up the tank when the level is low obviously the pump is required to transfer water from the tank to the toilets under all situations. What happens when there is a blackout or the pump fails??? I don't see how the toilets will fill up until the power/pump problem is fixed. With the mains backup system, where once the tank is low it reverts back to mains to directly supply the toilets, most of these systems cannot be used for external/garden use because there is nowhere to connect the taps legally as at any point in the system after the pump there is the possibility that mains water may be in use and therefore cannot be used for the garden. You would either have to run a seperate pump for the garden or use one of the few "mains backup" controllers which provide a separate external/garden outlet. The only one I've come across that can do this is the H2DUO which enables people to use tank water for the garden and toilet but once the tank is empty it only allows mains backup to the toilets. Hopefully this helps a few people understand the complexities of trying to kill two birds with one stone and use one tank for internal and external duties.
