Pro-Pal Series - Expansion Tank Pro Service Valve

Easily install, isolate, drain and replace any expansion tank and quickly connect an entire system to the cold water feed. The 3-way ball allows flow to pass between the expansion tank and the system, or isolates the system and allows for the expansion tank to be drained.

Good video but you fail to mention that not only is this device useful for tank replacement but also for yearly inspections as the water pressure in the tank must be relieved to get a proper air reading on the bladder otherwise you are just effectively reading system pressure and not actual static air pressure. This is a real problem on many systems that have just an isolation valve. Many mechanics just put an air pressure gauge on the tank with boiler pressure still exerted on the bladder. This of course does not give us bladder pressure but system pressure. I think if more guys understood why they need to use your valve, you would sell a lot more of them. Love them, use them on every job.

Thanks for the comment Anthony! We always appreciate learning about new ways that our valves can be used!
