PlumbingServices Water Heater Service by Greg Zimmerman June 8, 2019 written by Greg Zimmerman June 8, 2019 Recommended annually. Anode removed and tank flushed out. It’s not how much you use the water heater, but as long as it’s full of water, the anode is being consumed. – $25, additional $15 if a new anode is needed. 0 comment 0 FacebookTwitterPinterestEmail Greg Zimmerman previous post Toilet Supply Shut off next post Air Conditioner wireless control Leave a Comment Cancel Reply Save my name, email, and website in this browser for the next time I comment.
