I have installed my solar heaters on the garage roof. This is the 1st time doing this. The past few years they were on the ground. I have to get new hoses because of the location on the roof. My question is about the hose cuffs. The local pool store has 100' reel of black hose for $100. I would need to cut it in half. On the cut ends cuffs would have to be added. Every cuff that I've seen for sale online talks about it for a vacuum. Can these be used for my hosed from the filter, to the heaters, then back to the return jet? The other option that I have is to buy cut to length grey hose in 3' increments at $1.70 per 3'. I have a 1hp pump.
