Protective coating inside of Potable water tank
Protective coating inside of Potable water tank
(OP)
We have a water tank that stores water for plant process aswell as drinking purpose. the tank is rmajor repair.
We need to protect the inside of this tank and wish to use a good protective coating that would not affect the potable water quality also.
Please suggest is it allowed to apply protective coating inside of a drinking water tank? if not, what is the alternative??

Epoxies are common, 100% solids epoxies are preferable - I've had reports on some certified potable water epoxies which were installed in cold weather with poor ventilation. Notable water quality complaints (taste, odor) resulted.
