I do not know about plumbing at all, to be honest.
My question is - I was wondering if anyone knows why I need to stand for 1-2 minutes turning the shower head diverter knob back and forth until finally the water comes through the shower head and not the faucet?
I did have some luck with putting the hot and cold water handles about equal to each other, and that gave me water from the shower head within 10 seconds. My habit though is to have more hot water by turning the hot knob further than the cold to get the water toasty, but that's when it causes me to need to stand there for a prolonged time until the water comes out from the head.
Thanks, sorry for the long question]1
