I bought my unit in November 2005, but didn't get my pool finished, and the unit installed, until June 2007. The warranty is supposed to cover replacement of defective parts 100% for 3 yrs from date of initial installation, and at a charge of 60% between 3 and 5 yrs. I have determined I have a bad flow sensor (unit works fine when it's jumped). The Goldline rep I talked to said only way they can replace it under warranty is for me to pay a technician to come out and replace, and then they can only go on the date of production (I can provide them with plenty of "written proof" from plenty of people who helped me install the initial liner on June 2, 2007). I don't see why they are being so consumer-unfriendly about this. Anyone had a similar experience with Goldline?
