Shower plumbing for recycling water - with two=way valve closing waste pipe and pump lifting used water back to shower tap

摘要

The waste outlet (2) of the shower tray (1) has a controllable valve (5). When open this valve allows water to enter the waste pipe (6). When the waste valve (5) is closed, and a pump (4) is operating, the used water is lifted through a rising pipe (9) to the shower mixer tap (11) for recycling to the shower head (12). There are separate rising pipes for hot (7) and cold (8) fresh water. USE/ADVANTAGE - Shower plumbing with recirculating pipe saves water and energy used to heat water.
