I have always had great water pressure in my master shower. Recently we have been hearing a humming noise after the water was turned on. Today I went to take a shower and the water pressure was terrible. The water was barely coming out of the shower head. Is this a major problem? How can I fix it?

Thanks

John

Remove shower head. Look in shower head for blockage. Check water flow out of shower arm while you have shower head off. Post back if you don't find blockage in shower head.
