Hi debsiedoodle; and Welcome to The Plumbing Page. At AskMeHelpDesk.com. You're responding to a 7 year old dead thread so I gave you one of your own. Look in then upper left hand corner of the first post form the date in the first post before you post, Thanks,
Turn the water off to the shower and open up the valve to pull the cartridge, ( I'm assuming this is a one handled valve), Check the inlet ports on the cartridge and clear out any trash. Now turn the hot water back on to flush out the supply You should see a full /.strong stream as you do this. Reassemble and test. Better now? Let me know, Tom
