When you change between different cleaning solutions frequently when downstreaming this manifold is a great way to efficiently and easily change from 1 chem to another.
With having check valves it also allows you to mix say your soap and hypo mix.
Use the 3rd valve for something like benzo for for roof treatments.
You can easily add another valve to the end for another chemical or for water to flush your downstream injector out.
These are made to order but come standard with 3 valves and check valves and your choice in hose tail size on the outlet.
