input needed on back flow valve
Marco,
Two problems with teh backflow.
First one is abiggie.. Brass is made up of Copper. So that is a no go.
Secondly with all the stuff in a tanks water, including calcium, you will find that in time the back flow won't work as it will clog up and not seal properly.
Take alook at Flame*Angel's case on RC. She was running one and it didn't work when she needed it.
