How is water getting into our chemical tank? The banjo valve is in the direction to fill the water tank only (tested) and somehow it is back feeding into the chemical tank out of nowhere.Where where can we begin to look?
Either the o-ring, seat, or ball isn’t sealing or cracked. They sell repair kits for them as they are technically wear items.
It only happens when everything is off and not being used. Gotta be happening while driving. Do you still think it’s the banjo?
Walk me through the setup in the picture. I assume the hose reel is for your water coming from the job site. 3 way is split to feed water tank and ?. Label the hoses. Which tank is which?
