Bad city connection check valve cause low water pressure?

If the city water inlet is connected to a flexible hose/tube inside, it's a remote possibility the hose/tube somehow got kinked and is restricting flow.

Good point - that happened to mine. The city water inlet is the second from bottom white hose on the right in the photo I posted above. A short length of pex then flexible hose. I had to loosen the connections and twist the hose to get the kink out. You can see that it's still a bit restricted but not bad enough to worry about.
