Best Shutoff Valve Replaced in Kansas City MO

It's been 8 months since I got them replaced my old water heater and it is working good since then. Chase was willing to giving estimate based on the pictures of my existing component, explaining what's needed for the new installation and what can still work. Their pricing was lower than other large company in the market. The installation was neat, everything cleaned out after completion. He also explained to me how the atmosphere draft type of heater suffer when there is negative air pressure in the basement, and how my old unit is suffering from top panel rusted out. Adequate new air for the combustion, suggested me to install air louver allow air from the finished basement to supply new air.
About the Bradford brand heater he installed, I think it is good, we got 6 people showering same night(not concurrent) and hotter water did not run out.
