Customer called stating a previous plumbing company installed a Kenmore whole home water filtration system that was just installed a week ago and not working properly. When we arrived customer greeted us at the door stated he does not want to change the system and wants a plumber to only fix what is wrong with the existing system since the previous installer were unsuccessful in fixing the issue. The system is a 3 in 1 single tank filtration, customer had advised on site immediately when arrived that he disclosed to our office that has had several other plumbers out there previously and they all stated that they can only replace the system and not fix the issue. We proceeded to provide and estimate to replace because we advised the customer that is the only option we could provide and highly advised for him to speak to a representative from the manufacturer. At this time customer will be looking into manufacture alternatives.
