In the diagram above what is 230, 900, 901 on the hose attached to the pump?
Mine didn't have it and I see some dried washer fluid at the resulting hole near the pump. I am guessing some sort of pressure release drain that opens with no pressure allowing fluid to drain from nozzle hose but closes when the pump is on to force fluid to nozzles.
Thinking my valve (if it is one) may leak slowly draining the tank?
The front headlight washers may also be the culprit but it would have to siphon as the pressure hose goes up above the tank.
