Check Valve
Hi Chrys,
While using a needle valve in a low pressure setup, I was getting
water backflowing at least up to the needle valve. While waiting for
my metal check valve to arrive, I tried a plastic check valve after
the needle valve. As people had mentioned several months ago, this
made it much more difficult to control the bubble rate. When my
metal check valve arrived, I plumbed it as I had originally intended
which is before the needle valve. This works great. I am using M3's
Hexo-Manifold so this method allows 1 check valve to protect 6 needle
valves. By the way, their Hexo-Manifold valve is giving me more
control than needed for my low pressure setup and you get 6 valves
for $59!
