Description:
Homewerks Worldwide anti siphon frost proof sill cocks assure protection against freezing and undesirable back siphoning. Because they're frost proof, they can stop outside hydrants from freezing and bursting the pipes. Plus, the anti siphon feature protects against water siphoning back to contaminate the potable water system. Also, unlike anti siphon attachments, which must be manually drained to prevent freezing, the integral anti siphon design is self draining.
