We continue to make a wide range of controllers for rainwater toilet flush systems. Pictured below is one of the simpler units for use in systems with just one float switch located near the top of a toilet cistern, with the supply coming from a water butt that has a pump with run dry protection or a well with a 100% consistent supply of water.
As the inside of a toilet cistern can have very turbulent water, this controller is built with automatic time delays. The float switch has to be detected to be down (after toilet flushing) continuously for two seconds before the pump will be turned on, and then the float switch has to be detected to be up continuously for two seconds before the pump will be turned off again (cistern refilled above the height of the float switch).
We also make controllers for systems with header tanks feeding multiple toilets, up to three float switches, with displays to show system status, and/or dataloggers to keep track of number of flushes and/or the volume of rainwater used etc. Some of these are detailed in our rainwater category.
If you require any kind of rainwater toilet flush pump controller, please email firstname.lastname@example.org with details of your planned system and requirements.
