“The Honeywell zone valves I replaced had been in service for more than 20 years with no problems. Only recently did one begin to stick in the open position occasionally, so I thought it prudent to swap them out before winter sets in.”
“The hydroxide heating system in the house stopped working, as both zone valves quit. I was able to get 2 of these valves within 2 days of ordering and got the house warm again. And at a great price.”
“I needed a replacement terminal zone block, as my 58 year-old current block broke and the valve would not shut off. I really didn't need the valve, but I had to buy it to get the zone block.”
