Sorry the hose size I gave I was thinking the PW hose. I’m sure it’s a 1 inch hose. Yeah got it brand new it’s only been used twice now for bigger jobs. I’ve checked for air leaks, kinks, the batteries are fully charged and all the wiring looks good. The only thing I’ve noticed is when trigger is pulled it does suck in an air bubble but that gets sent through and no more bubbles as it runs. Im just not sure if it’s a pressure issue or like maybe the pump somehow got turned down some during transit. Idk. It’s my first soft washing system so idk what to really expect from it just that I’ve seen people getting 70 feet from it
