Replaced a liner last year. Provided top line model at best cost he could. Work was done quickly and professionally. I had constant algae ALWAYS return and mysterious breakdowns of Polaris motors EVERY season w pens pools over 10 years.. They would forget to show sometimes. I changed to faithful. Got a better price. AND NOTHING HAS BROKEN DOWN! Chlorine is always kept up and balanced. They show every week and clean it properly. FAITHFUL to me is the new good service. Pp acts like kings. Faithful has been great. I recommend them to our patients and readers here.
