KruppI wanted to pass along my sincere thanks to all the people at O’Brien Pool for the many years of excellent service. I started using you guys in 1999. Over that time you have installed a new liner in 1999 as well as a new salt generator in 2012. I couldn’t have been more pleased with the results I have achieved. I estimate the Salt generator has actually paid for itself in the two year period. I have a large pool (34,000 gallon) and was using over $750/yr in chemicals along. Now all I use less chemicals and my pool never looked better, not to mention the feeling we get when we swim!
