With a Hydraloop device, you can recycle up to 95% of shower & bath graywater and optionally 50% of washing machine graywater – which enables you to reuse 25-45% of the total in-house domestic water. Through innovative and breakthrough technology, Hydraloop recycled water is clean, clear, safe and certified and can be reused for toilet flushing, washing machine, garden irrigation and/or swimming pool top-up.
Hydraloop H300 has been tested and certified to NSF/ANSI 350 and IAPMO R&T.

Input specifications #
Hydraloop requires a backup water connection in case there is insufficient recycled water available. Backup water can be mains (tap) water, treated rainwater or treated well water.
| Input Outlet | Water Delivery | Pipe size |
| Backup water | permanently pressurized min. 3.17 gal/min required | 1/2″ BSP |
The backup water enters the Hydraloop via a safe air gap (T4), ensuring no possible connection between (recycled) gray water and backup water.
