Completely impossible to get any after sales service! Troy from Titan Water Systems, made two appointments to supply and install replacement filters for the RO system. He never showed up for either appt and never even called to cancel, so left us sitting at home waiting for him. When I followed up via text to see where he was, he wouldn’t return or acknowledge messages. Same problem a couple of years ago when the system leaked. We finally just fixed it ourselves. Stay away from this company and individual!
