Review on PEX End Cap Plumbing Fitting - SharkBite U514LFA, 1/2 inch, Push-to-Connect, Copper, CPVC, Brass by Alexander Morgan

I bought a new industrial house in 2000. It's very big, 2300 square meters, I took care of my grandmother with Alzheimer's for 15 years. As she passed, this part of the house (designed as a duplex), was the main house, and then the mother-in-law's territory. As nobody lived in the area, we never went there. Fast forward to 2020: an under sink leak in the main part of the house repaired with a shark bite. Then, after 2 months, a drain tap under the sink in the kitchen was leaking, repaired. One day the floor in the laundry room was wet, the next the sink was leaking. Another one a few days ago in another bathroom and when I turned the water back on it was barely moving which means I'll have to look for another leak. After about 10-14 years, replace all the connections (switches) under each sink and toilet, otherwise you will regret it. 19-20 seems to be the time when they all fail at the same time. I need a new house now, the damage is way more than I want to pay for repairs.
