aqua hot
2013 Diplomat. I have heat on zone 4, but only blows cold air in the other 3 zones. Any ideas why?

I will third that. Don't "beat on them" just a smack with the handle of a large screwdriver and depending on the ambient noise, sometimes you can actually him the "click" and then the flow of glycol. They will be coming right up out of the top of the enclosed unit and are merely a brass union looking part with the PEX line coming out of the top. They may have a small cap on one side. You can either feel the lines or use an infrared gun to see the temperature differential on either side of the check valve. Or just give all of them a tap and call it a day.:)
They will stick if not used for an extended period of time. Also, whenever you flush your glycol system try to keep the mixture as close to 50/50 (boiler glycol/distilled water) as possible. Too much glycol can magnify the sticking issue.
