I am using a brass valvw on my doser that i use for kalkwasser. I assume that brass is okay to use but am not certain. If anyone knows of anything harmful happening from using brass i would like to know. THANKS
Some 30 years ago the University of Washington marine labs at Friday Harbor
had a flow through system that was all glass or glass-lined. This included
the pump that ran water through the system. I should emphasize the system
was immense, it served about 10 separate buildings and probably entrained
upwards of 100,000 gallons of water at any one time.
A new maintenance man was on call one evening when the pump broke down.
Rather than try to fix the glass-lined pump, he fastened on a brass-lined
pump. The residence time for water inside this pump was less than a second
(from the bay thru the pump into the glass pipes of the system). Within 1/2
hour of the pump being installed researchers noticed mortalities of their
animals. Within about 2 hours effectively every organism in all the flow
through tanks was dead.
