      Recently had leak in nipple on a 5 to 6 year old gas fired water heater. I replaced nipple. I drain tank down some before making repair. Hot water heater is in the attic of 2 story home. I now have an intermittent problem of vibration in piping on downstairs kitchen sink on the hot water side. It is a MOEN washer less single handled sink. No leaks packing and it functions properly. Any idea what the problem is. Do I possibly have air trapped in the line. Will it clear itself or do I need to somehow depressurize the system and bleed off trapped air, OR do I have another problem. Any suggestions would be appreciated.

      Mark:–Go to the water heater and check to see if you fully opened the water supply valve after you worked on it. Sometimes old stop valves will have a washer that vibrates between the stem and seat if not fully opened. This humming or chatter is transmitted by the piping to other areas of the house. Hope that solves your problem…Bud.
