Open hose coming from the water pump
While looking for something that fell out of a drawer I took the panel off under the sink of my Sprinter, with the panel off I noticed a hose coming from the water pump that was open on the other end. there was a shut off valve at the pump end. Can someone tell me what this hose is for.?
