SharkBite fittings are very cool but they are a VERY costly method of repair. There are times when one can be a life saver, and the ability to release the grip and pull out the pipe can be useful. But I would not trust a fitting that has been reused to not leak.
I much prefer using regular crimp rings and Pex fittings. The old school copper crimp rings are a royal PITA, but the SharkBite stainless ones are wonderful, but OTH you need their ratcheting crimper to install them. To remove one, you just grab the crimped part with vise grips and twist it. The copper ones have to be cut off! You can buy the tool for the cost of a handful of push SB fittings; the regular brass PEX couplers, elbows etc are cheap. The stainless clamps are only 50 cents each.
This tool will do everything from 3/8” all the way up to 1”, so it works nicely for home repairs too, like your irrigation system..

As an older gentleman I have a hard time crimping the 1” rings due to hand and arm strength. Slipping a couple of pieces of hollow pipe over the handles gets the job done easily.
