The Galv Baths Are Made From Mild Steel That Has Either Been Hot Dipped In Zinc Or A Pre Galvanised Sheet. This Gives The Material A Sealed Coat That Prevents Rusting .These Items Can Also Be Used As Decorative Items In The Garden.
I installed all the filters, including the membrane .After the replacements I tested the water and a must say these do work ,kettle is clean from scale build up as my town water is hard water (has lime scale build up), the water also taste good too, I will buy these again in the future
