“Hi I was pleased with the product. The only thing that should have been revealed first was. I found a red tag that said that I should set the valve on open, then solder with low heat. After I had it installed, I found out that all I had to do was take off the top. That removed all of the working parts. I then would not have had to worry about damaging the control ball. Thanks for the good product. Next winter I may have to order a booster motor. I do not know yet, but this past winter before I installed the valve, I could not get enough heat when it got colder than zero degrees.”
