big problem. Im currently at a home with an irrigation system. when it kicks on the check valve on the cold feed for the hot water recirc for the water heater seems to chatter like a machine gun. would a ball check with a hammer arrestor and an expansion tank or two help. if i shut the ball valve for the cold feed off the irrigation works quietly. any ideas would be great. thanks.
I'm troubleshooting a gas boiler next week and I admit I dont often troubleshoot controls,transformers, hot surface ignitors etc. I usually use the trial and error but I would like to broaden my horizons to become a better tech. How can I test a transformer on a resedential boiler , spill switch , or igniter ? electrical is not my forte but i realize it is not as complicated a i thought . Anything would help. thanks
my dads steam boiler is making steam when it calls for hot water. low limit is at 180. did it fail?
