Hot water side wears out faster. Seems to me if a plastic screw cap on a bottle of carbonated pop stays sealed under pressure, there should by now have been innovations in the plumbing world for things like the rubber washers, seat assembly, etc without having to replace faucet. i don’t need a life guarantee but a year without repair would be nice. Three flights down to turn off water, 3 back up to repair, 3 down to test drive repair, 3 up to see if test drive failed, etc etc.
