We have a Puronics water filter system for our house. It is time for the annual renewal and check up of the system. I have left several messages over the past several weeks, both texts and voice, to the local dealer, LCRG Enterprises Inc., in Belleview. No one has responded. Does anyone else with a Puronics system have this problem? Do you know if the company is still in business? I'm not sure who else to call. Thank you in advance.
