Hello,

Last summer we upgraded our boiler to a Triangle Tube prestige solo, with a Smart30 indirect hot water tank... We live in an area where city water has a high mineral content, and they flush the water mains frequently, leading to discolored water. We are starting to get discolored hot water, all he time, so I think the tank needs to be flushed, but can't find in the manual how. I have tried calling the installer, but he isn't returning my calls. Is it just as easy as my last conventional gas fired hot water heater - just open drain valve and let it go until the water turns clear?

Thanks for any help.
