We're facing a new liner, and I'm trying to understand the costs. Using this site, I get the following for our existing pattern.
Group H - Blue Hampton 20 mil - $1544
Group I - Cambridge 30 mil - $1739
Group J - Blue Hampton 28 mil - $1836
Can anyone explain why the "Group J" is thicker, cheaper, and called something different? FWIW, our existing liner (Cavalry/Ft Worth) is labeled Cambridge 30 mil on the paperwork.
Also, our warranty shows 20% ($347) prorate at less than 10 years (Installed ~8/1/06), 15% ($261) for 11 years. Is it worth the $87 to change it now, or should patch and wait until spring? Anyone know if the warrant date is based on notifying them, or placing the order?
