Arrived in site customer stated that they would like their tankless serviced. After inspecting unit. We found that this is the customers summer home but they had renters who come down and use the home so the unit is being used more then 6 months out of the year. Myguy plumbing gave customer options to flush the tankless. After the flushing was completed, MyGuy plumbing cleaned out filters and made sure everything is working as should. At this time everything is working as should no issues
