Upon arrival customer had a leaking hose bib that needed to be replaced. Further inspection water heater had a slow leak out of the dielectric nipple on the hot side of heater. We pulled out nipple after disconnecting heater from supply line and leaned up threads for reinstall of supply line. Water heater is tested and operational as it should. Thank you for calling John The Plumber and be sure to call back for any plumbing needs! -Shane
