GSHA Services, LTD completed a plumbing diagnostic and water treatment service call at a home on North Cedar Crest Drive in Lake Villa, IL. The homeowner is on a private well with a whole-house sediment filter and ultraviolet (UV) water purification system, and was concerned about water quality and a UV alarm. Our licensed plumber inspected the well pressure tank and supply piping, checked the multi-stage filter housings and cartridges, tested the UV sterilizer ballast and replaced the UV lamp and quartz sleeve, then flushed and sanitized the system and verified flow, pressure and leak-free operation at every connection. We also inspected the bathroom exhaust vents and ceiling fixtures the customer asked about while on site. Well-water homes need annual UV lamp replacement and filter service to keep drinking water safe, and GSHA offers flat-rate plumbing diagnostics with clear recommendations.
