Function:
To protect the potable water supply from backflow from a non-
potable source due to a drop in supply.
Protection:
Pressure i.e. backsiphonage
Installation Instructions
Requirements:
1. Install 12" (300mm) above highest point of downstream piping.
2. Install bonnet side up and allow for accessibility for testing/service.
3. Install where discharge or spillage is not objectionable.
4. Do not undersize supply or oversize the valve in relation to demand.
5. Do not install where backpressure can occur.
6. Protect from extended freezing.
7. ASSE Standard 1020 requires that the atmospheric vent valve remains
open until the valve bodypressure exceeds 1 lb. Until this pressure is
reached, some amount of spillage will occur at the atmospheric vent. In
order to minimize this leakage on start-up, close the downstream shut-
off valve and open inlet shutoff valve quickly
Recommended
Service:
1. Test periodically as required by local jurisdictional authorities.
2. Open test cocks to drain in cold climates if only operated seasonally.
3.
Replace
rubber goods every 5 years.
