maple crest, how did cleaning the tubing work ? do u like doing it better than rinsing? i think next year thats what im going to do is do it under vac and not rinse but i dont know, i already pulled my pumps so i gotta rinse now with my 1inch pump maybe next year ill use air and water but a guy at leader said it just turns to vinage and rinces out the first run so who knows, im sure not washing dont affect how much sap u get if ur using new adaptors every year
