THE REFINER AN (ACID NEUTRALIZER)
Acid Neutralizers are used to balance out specific water problems. If your water is acidic, it can be extremely corrosive to your plumbing system. Signs of a low pH are blue green stains on toilets, fixtures and tubs, which means your water is eating away at your pipes. If left untreated this will lead to problems with leaking pipes and costly repair bills. An acid neutralizing filter can treat this issue and prevent any further damage.
