    • GARBAGE!!!!!!!

      Bought this along with the panels. What Garbage. So far 3 connectors have split. They can not take the sun. All are now cracked. The Diverted is not usable with normal 2" pool plumbing. Sitting in the box it came in. as is the backflow valve. Had to buy a 2" diverter. $$# and 2"backflow $^% . Have had to replace all connector which are about $#$% each. About the only thing that is useful in this kit is the mounting hardware otherwise save you money and buy you own connectors.
