Wow the difference between that threaded brass and stainless piece is incredible. The brass looks warped, worn, and pathetic. Thanks for pointing out the evidence of a leak. I'll check that packing seal adjustment when I have some downtime soon.
Man the truckmount sounds smooth and consistent now. This thing is a workhorse! I thought the 120 gallon fresh water tank would go further than it does when wanding at 400 psi, the recovery tank fills up quickly too. Maybe I am wrong about the size of them. I need to map out dumping and filling areas. At least start screening customers on the phone to see if an outdoor faucet will be available at their home or business.
