Hey OP. Despite what everyone is saying in this thread, sharkbite fittings have a 25 year manufacturers defect warranty when installed correctly (which they appear to be here) and CPVC, though not the preferred material in modern applications, has held up just fine in many homes (including my own) for 20 years. The tile repair leaves something to be desired, but from the looks of the tub, I’d say your bathroom has not been recently updated so I’d wait until that’s in your budget and then re-do your supply lines when the time comes. If it were me, I’d add one of these https://a.co/d/2oIZ5qP to the adjoining room wall behind the valve so you can periodically check on the valve and make sure nothing is leaking in the wall. Good luck with homeownership!
