Comments about 3/4" Sweat Connection Zone Valve, normally open, no manual opener (24v):

I have been using this product for about a year when I left the unit powered off for a day, the ball inside never resealed to the port after that. This unit still leaks water and circulates heat when fully powered and actuated. The volume throughput is also incredibly lacking in that the flow hole is about the diameter of a pencil if not less. That is a big difference in a 3/4" line. I have spent a lot of money on this site and I have to say, this is not the first poor product.
