My question is... Why do you have straw anywhere near your pump and pool equipment in the first place?
Clear all that out. If any equipment overheats, you could start a fire with all that dried straw anywhere close to the equipment. You live in the desert - straw, grass, weeds, debris shouldn't be anywhere near the pool equipment.
As for the air coming out your returns, you probably have a suction side air leak somewhere. Or possibly, your pump rpm may be a little too low and the small bubbles produded by your SWG are collecting somewhere on the return side of your plumbing. Once enough of the small bubble collect, they form a larger bubble which eventually gets pushed thru to your pool returns.
But most likely, it's a suction side leak.
Remove pump basket lid, clean all mating surfaces and o-ring, lube o-ring and reassemble.
If you have a leaf canister, do the same with it.
With pump off, listen around all Jandy valves for a hissing noise - which would signify an air leak.
Search the forums here on other ways to find a suction side air leak.
