Contacted brass built thru a referral. To work on my tankless water heater the circulation pump burned up. They replaced the pump and suggested we add a filter to help stop the hard water clog up the tank. The initial verbal quote went from 700 to 1300, after the were done. The kicker is that 2 weeks after I started getting a error code on the heater and when I contacted Charles he said that I isn't related to anything that they have done to the heater and will not even come back and look at it or give me a referral to anyone that can help. So use at your own risk!! Apparently Charles doesn't like my review!! He sent me a text telling to delete my review!! The same day I posted it!!!
