Rubber gasket is no good. Sometimes it seals and sometimes it doesn’t. Pump will run continuously if it’s not sealed. Also it falls out when you take the unit off
Besides the gasket problem. The units battery only lasted 10 times then went dead. will not charge. I got 3 months of light use. Now looking for a battery. Warranty ???
I have used my PTT daily for my small pest control company. It’s worked like a charm and I have not had any issues for 2+ years. Would hate to go back to pumping….
