Windscreen washer

[Mike350]

Hi, the washer fluid seems to evaporate very quickly from the reservoir on my 2004 350SL, and needs frequent filling even though I’ve hardly used the car in mucky conditions, as only use it when the sun’s out (frequently recently!) so just an occasional use of the windscreen washers to clear squashed bugs en route. Last time I filled the reservoir water ran out the back of the car from a drainage pipe?

Any thoughts/tips?

Thanks

Could be a connection to the breather pipe coming off, this was mentioned on t’other side
