boiler shut off...
I turned off the main water valve at the metr to repair a small leak near the meter and opened a meter bypass while working. The water was on thru the bypass and I finished the repair and opened the meter valves and closed the bypass. A few hours later, I realized the boilers stop heating the water for heating and domestic hot water. A boiler man came and said that both boilers stopped working because both regulators closed and would not open so he jump-wired each until he could buy and replace each one. the boilers work fine now and I want to know if closing the meter valves caused this? I had the bypass open but I did close it off and on a few times just a few seconds each time to test if the meter valves were holding. The water supply was totally off for these brief seconds and that is the only thing that I can think of that may have caused these 2 regulators to go haywire but it doesn't seem right???? I wasn't there when the boiler repairman came so I couldn't ask him what happened. the reg. are penn brand and have a temp. gauge near so I guess they regulate based on temp. and/or pressure? Any ideas why this happened so I can avoid next time....??? many thanks for any advice....I may not have a chance to question the repairman man later...thanks to all....Mark

if pressure was taken off them(during repair) one might of locked up but both seem to be the old repair fix of i couldn't find the problem so i'll change something?your saying he JUMPED them to get the boiler to work but is it that the low water limits opened up due to a lack of water in the boilers from the fix which is whow they should work!this is boiler steam boiler you talking about not a hot water baseboard set-up.what is a mystery is there are no wires on a water regulator for a boiler...unless i am missing something here

You have to be using the wrng term with "regulators". Water would have no effect on pressure regulators in the gas side of the system. Are you sure you aren't talking about aquastat relays or something else? The description doesn't make a lot of sense.

Get your repair guy on the phone and talk to him. Let him walk you through what's going on with your system and how he came to his planned solution. Be sure to take notes and ask questions about anything you don't understand. Everyone in the trades has a cell phone. And since it's impossible for you to be there when he does the repair, it's important for you to fully understand what went wrong, why it went wrong, and how is it safely repaired. Most trades people don't mind dealing with reasonable people who pay attention, listen, and don't waste their time with attitude or rambling. Good luck and let us know how everything plays out.

boiler shut off
I think you are correct BIG MIKE, I may have called the unit a regulator but it is not. I thought I could remember the layout so that I could explain it and someone would recognize what part I was referring to. Now as I am trying to recall the configuration I'm not sure what I was looking at. I think this part was on the water supply to the boiler, and there was a manual valve and then a few inches past was this part. It was on the water supply also and it had a small square unit on top inside which had some copper wire fastened under screws. The repairman had unsrewed the two wires and connected them directly to each other so as to bypass whatever had malfunctioned inside this unit. he was bypassing this mechanism temp. to allow the boiler to function until he could replace these two units(each boiler had one). I am sure that these simultaneously malfunctioned and it was a result of something that happened when I was turning off the main water valve. I apologize if this is still confusing because of my poor memory but I will talk to the repairman and take notes so I know what went wrong. It bothers me when I don't know what happened and I don't want this to happen again. Thank you kindly for all the good advice; this is a great way to get help for all of us hackers trying to learn....mark

Small box with wires and screws sounds like a low water cut off or auto feeder. Is it a steam boiler?
