Vacuum Breaker on Toilet Hand Sprayer

Hi All,

Can anyone provide reasoning to why my 65 Caravel has a factory installed(?) Watts 288 Vacuum Breaker Anti-Siphon valve on the toilet hand sprayer only? The inlet water for the flush valve on the toilet is a straight connection, without the Vacuum Breaker valve, but the hand sprayer has the valve?

I would think it would be the other way around. I'm thinking about removing the Watts valve and just straight piping the sprayer since the Watts valve is leaking anyways...any have a reason I should keep it? The hand sprayer would have a hard time stretching to fit in the toilet boil for the unlikely scenario of siphoning out of the toilet into the plumbing system.

Actually, it does make sense. If your hand sprayer were to be left lying in the sink with the sink full of water, it would be possible for graywater to be siphoned back up the hose into your freshwater system under certain conditions.

A handheld sprayer is the only water connection in your system where the freshwater outlet can accidentally be submerged in graywater, and thus the only one that needs an anti-siphon valve.
