We bought a house with a pool in April this year. I couldnt stand seeing the pool equipment bake in the Texas sun so I built the cover shown below. 1" PVC frame with inch and a quarter supports. The inch and a quarter slides over the one inch embeds in the cinder blocks. Theres a tee at the bottom of the 1" PVC inside the mortar filling the cinder blocks, which act to weight it down. Whole thing can either lift off or swivel up from one side.
