I am installing an irrigation system in my yard, and am tapping into the main water line. It is 1" pex pipe, and I plan on using some pex compression fittings connected to a PVC tee for the sprinklers.

My question is, how reliable are these pex compression fittings? This connection will all be buried underground, and after making sure it isn't leaking when I attach it, I will cover it with dirt and likely never see it again. If it ever begins to leak, I will never know.

Another question... how else can I tap into a 1" pex pipe? Thanks.
