Gaffrig muffler air pump?????
After sitting all winter, my gaffrig air actuated mufflers won't stay closed. When activating them, the pump closes them just fine, but they open back up after about 5 seconds. I assume there is a bad valve or something that is letting the air escape. I can't find anywhere the air is leaking upon initial inspection. There appears to be some type of solenoid attached to the pump. Not sure if that may be the problem and it is allowing the air to leak back.
Last year they used to stay completely closed for about 15 mins before reactivating them.
Ideas????????

The solenoid dumps the air out of the lines after the pump shuts off, allowing the cylinders to retract. You could have a leak there, in a line or a piston seal in a cylinder. Or the pump could be worn out and not supplying sufficient air.
If you have the room, you can hook up a pump to a 1/2 gallon tank and run a pressure demand switch. Then the pump only runs when the tank needs to be refreshed. The pump will last much longer doing that- those pumps only had short duty cycles- like 20%.

I like the idea of adding a pressure demand switch and a small reserve tank. I may have to look into that.
