running tandom guzzlers

[Windy Acres]

has anyone set up 2 guzzlers to pull on the same line? i was thinking put a seperate check valve before each pump, and have them in paralell, so if one loses a diaphragm while im at work, at least we would still be pulling with one, and we would get twice the cfm

Seems like it should work.

For anyone running the double guzzler, if one of the diaphragms gets a hole in it, do you lose all vacuum??

As long as the umbrella valves at inlet and outlet are still intact, a bad diaphragm shouldn’t affect the other one, they are separated. The valves will block sap from flowing in reverse so the good side continues to pump and the bad side is just free wheeling. I am setting up a 24 volt G2 Guzzler with my controller now, that would be an interesting test to do, remove a diaphragm and see what happens.

It will pump , but will leak on the damaged side. I seem to go through a diaphragm each season. The housing is soft be careful when tightening.
