The when I turn it on the pump is almost silent (at least compared to the AC version which had a distinct hum/buzz of moderate volume). Battery measures 12.8v with the charger connected pump off, 12.5v when I turn the pump on. It only got to 32-33F today after a big freeze so tubing is still pretty much frozen, but the pump doesn't even seem like it's trying to pull anything and vac stays at zero, albeit there's no liquid in the diaphragm. It just seems too weak to me. Am I wrong and that's just how quiet the DC's are?
Huge flow coming tomorrow so I want to make sure I'm ready!
Have you tried setting it up so that it pumps some liquid through it to see if it is even working? Sounds like maybe it’s not working.
