The following shower handle and bathtub faucet both require special valves according to Lowes. I have spoken to a few people and contractors who say that they are not needed because of "sharkbites". Do most plumbers circumvent these "Required" valves with sharkbites. I dont really know what sharkbites are (or understand how they work). The valves seem to address pressure balancing?
Would skipping the required valve affect product warranties?
These valves are very expensive. If I can avoid using them, I am happy to do so. I just want to make sure that I am not missing something important.
Edit:
Its interesting that one review says that these valves are for shutting off the water at the fixture instead of further downstream. I already have a water-shut-off at the shower. I thought it had something to do with the water pressure because they call it a "PosiTemp® pressure–balancing control valve"
"The separately purchased rough-in valve is used in combination with this valve trim kit and the rough-in valve includes the cartridge and, if you want, stops. Stops allow the hot and/or cold water feeds to be turned off so that the cartridge can be replaced without shutting off the water further upstream or to the entire house."
