The Auto-Drain Shower System is now equipped with a diverter for dual spray showers, and it comes in a low flow for areas where water conservation is important. It was initially designed for stagnation prevention in hospital showers but as engineers and facilities managers find out about it, they are interested in using it to purge water in showers for long term care, schools, athletic centers, gyms and other facilities and especially if there is intermittent use - like offices and campsites.
