It is not that it is not up to code, it is just that after a while, the rubber gaskets dry out from the water, and will not seal, or even worst, will not move. Ball valves can do the same thing if left to sit for a long period of time, without rotating the valve.

At least every six months, when you change the clocks, go through the house and rotate the valves closed & open to make sure they still work. Replace any that allow water still through, or even gas, if used for gas shutoffs.

gate valve

Hi I have a gate valve in my condo and it's not working and I can't turn the water off without turning all the condo units (everyone in the building) so I have to replace with a ball valve. If I was you, I'd swap it out.

when we are ask to bid a water heater or any other job....we always up grade plumbing if its needed for the purpose of a good install and future service ...most if not all the locals do the same thing because it is the proper way to do the need to bring up extra cost if its already included in cost of install been working for me

Bad sales pitch I guess.
