Need some suggestions from you guys
PDQ M5. Soap and wax is watery and not foaming. Checked air and had good air flow. Noticed chemical pump pressure was low only about 60 psi. Normally runs over a hundred. I’m hoping the check valve might be blocked and can’t open all the way. if not do you think it is the chemical pump failing? At the cost of new pump I would like to eliminate other possibility before buying new pump. Any suggestions will be appreciated
thanks
