Inquiry (采购产品): ESP Zone Valves I have a 3 zone heating system with 3 ESPo75C2 valves that were installed 4 years ago. I have already replaced one 2 years ago and may need to replace another. I need to know why these valves are so fragile, and price for a replacement. **** Hidden Message ***** kenneth bruen 2933 hyatt st yorktown, NY 10598 USA Company: KB ASSOC E-mail: brue@netscape.com **** Hidden Message ***** brue@netscape.com
