What is the life of a membrane? If it goes wrong prematurely, will it be replaced free of cost?
The life of a membrane depends highly upon the inlet water quality. If the TDS level of the inlet feed water is upto 1500 PPM, then the approximate life of membrane would be around one and a half years provided that the specified consumables/cartridges are replaced timely and the feed water conditions are met. If it goes wrong prematurely, it will be replaced on actual cost because being a consumable it is not covered under warranty.
