FYI My frabico Sun Dome failed after 3 seasons. The Vinyl turned yellow and brittle. It torn all over. They want $1000 to replace vinyl dome only . Doesn’t seem right 

Way too many and so brittle you bend it it cracks.Can you patch or tape the holes?
I know, they told me they last 3 to 5 years, but no one will go in the pool if I have don’t have a dome. The southern exposure is what turned yellow and brittle. I’m stuck buying one every three years. I guess the money I save on just using chlorine helps.Sounds like UV damage. Is there any sort of warranty? Unless you replace with something that has better UV protection, you will likely have the same experience.

I have a heater too, but the water has to be like 90° for anybody to get in it. The dome pretty much holds that temp when it’s hot out. I only use heater in April and October. There’s too many leaves and acorns and it’s too hard to pull the cover off when we had a net. The dome was the best thing ever. No maintenance. Never had to clean. Just bleach. For such a disposable product you would think it would be cheaper. I’m just venting. Thanks for listening.Is this a temperature problem? How much would it cost to heat the pool?
Yeah probably comes in big sheets though and I would need it contoured with seams. It’s a massive sheet of vinyl 18x33. It’s hard to pull up and take down. The sun dome is really heavy duty and thick and with all the pulling and stretching it still didn’t rip. It justed ripped this year. Dried out apparently. Maybe there’s other manufactures but I could never find one online.Assuming the framing is still good, why not recover it yourself with a more UV resistant plastic? Sure looks to me like a money saving DIY project.
