Guys - we keep seeing discussions where people are confusing Flush Valves with DI Bypass Valves. They are two very different things, and serve very different purposes.

A FLUSH VALVE is essentially a flow-restrictor-bypass, and is therefore installed on the concentrate (waste water) tube. It allows water to rush through the RO membrane housing, and through the RO membrane to clean both. Flush valves can be manual or automatic.

A DI BYPASS is a 3-way diverter valve (http://www.buckeyehydro.com/tds-creep-bypass/) installed on the permeate (RO water) tube. We use DI Bypass valves to effectively deal with TDS Creep.
