Loss of hot water in Moen Shower facet - single, pull handle
I have lost significant pressure in my shower equipped with a Moen single handle pull out and rotate - R or L. I have a 2nd shower with identical unit - swapped cartridge - no change. Pulled out the posi-pressure valve on the hot side and found some debries, no change in pressure, may be worst. After removing debries I left out the cartridge and flushed the facet, even dragged my small air compressor upstairs to blow out. Any ideas on what is causing the issue?
Thanks,
Jeff
