At Webstone, we’re always listening. Thanks to our partnerships in the field; we recently introduced the Expansion Tank Pro Service Valve. This latest innovation in our Pro-Pal line of Step-Saving Valves is designed to streamline installation and facilitate replacement of any Expansion Tank. This full port, forged brass fabricated assembly eliminates multiple joints and fittings reducing labor and material costs as well as potential leak paths. 
 

The Expansion Tank Pro Service Valve
4-in-1 Alternative To 2 Tees, Ball Valve & Boiler Drain
Eliminates 5 Leak Paths
Saves An Estimated 45 Minutes Of Labor

The ETPSV installs easily, quickly connecting to the main system, supply feed, and expansion tank. When the tank needs to be replaced, the main valve isolates the unit from the rest of the system. Opening the drain valve releases pressure from the waterside of the diaphragm; allowing the water to drain neatly from the tank into a bucket below. This design saves the contractor from having to clean up an otherwise unavoidable spill.
