Sorry but this is not correct. The anti-siphon valve is almost always apparent. These spigot valves are not very good and fail pretty regularly so I would not trust my drinking water to them.
Also an anti-siphon valve only works if it's above the water lines. If you store a hose above the spigot like many people do, you've just defeated the valve.
- lostlogin 9y agoEvery outside tap here in New Zealand is required to have a back flow preventer (is this a different thing?). They all passed the recent test they had which was required by the local council and they are all pretty old. The 'check valve' is required to be replaced every two years as it can't be tested according to the documentation here. I don't known what this is and don't have one.
