The windshield washer and headlight washer pump are clamped in the reservoir with a sealing grommet. If the pump is still running and you find that the reservoir is emptying very quickly, there may be a leak in the pump, but in most cases, the problem is with this seal.
Over time, the rubber dries out, hairline cracks develop and cause leaks.
