The Ergo non-concussive basin tap for pre-mixed water is designed and manufactured from the highest quality materials. Time Delay Self-Closing taps are operated by simply pushing the tap and water is dispensed. Allowing the user a more controlled use of their water, this timer tap turns off automatically after a set period of time, which not only reduces the risk of people leaving the tap on and flooding an area but can be extremely cost effective as well.
