The shower was running then there was a clunk sound and the shower died down to a trickle. The Tub faucet seems to work fine just when I switch it to the shower there's just a trickle. Same thing for both hot and cold water.

Remove shower head and see if you get normal flow.

I took the shower head off and it seemed to have a steady stream.

Hi RobertNC80

Clear the shower head of debris (look in neck of shower head...should be something clogging the screen), or replace it entirely...will fix the problem here!!
