Purchased to water plants from 5 gallon bottles. Easy to install. Noticeable, soft hum only when water is running. Not loud or unpleasant. Tubing easy to uncoil, recoil. Does not leak. Purchased 'PureSec 1/4 Water Line Fittings 1/4 Push to Connect Fittings for 1/4 OD Tubing(1/4 Ball Valve' for the end of the tubing to control/ stop the flow while using. Does not completely empty the bottles; stops when about a half gallon is left.Convenient as I can water plants where they sit without taking them to the sink. Pleased with this application.
