Water Filtration System Repair near High Park Blvd. I received a call from a homeowner who reported that their whole-house water filter was leaking. Upon inspection, I found that the o-ring on the filter housing was damaged and needed to be replaced. I also found that the filter itself was clogged and needed to be replaced. After replacing the o-ring and filter, I tested the system to ensure that it was no longer leaking and producing clean water. The homeowner was pleased with my work and relieved to have a reliable whole-house water filtration system.
