I was looking from a solution to replace an external water supply (failing) for watering. And I finally opted for this adapter I laid on the kitchen faucet. Impeccable, not a drop of water escapes or at the tap or along the pipe as happens sometimes with fittings. The filter is screwed gardena instead of this filter on the tap, it performs the same functions as your standard filter. And when you need to water it sets the "valve" Gardena on the filter. Déboitage casing and ultra fast and easy. I highly recommend.
