where can I buy solar panels for our pool. One froze.
Lucille,
I suspect you own a drain back system. This system was designed an sized to your specific pool. You should look for the brand name or the phone number for the installer. There is a chance I can identify the system for you with a photo?
How did it freeze? It is sealed and should not leak even if frozen. What was it doing in the pool?
