My plumber installed new shower diverter-spout below. The last one was dripping. While working, he also misaligned the shower top knob incorrectly, so Hot Side brings cold water, and Cold side brings hot water reversed.
We're bringing plumber back to fix next week. While I operate in this reversed mode, will it cause any damage to the diverter/spout I just installed? Or nothing to worry about? He didn't even replace the cartridge, was just rescrewing the top shower knob etc to fix the slight dripping/leak.
