• Drip Depot Hendrickson Bros Hose Thread Backflow Preventer

    DG41 Hose Thread Backflow PreventerBackflow prevention devices are recommended with any irrigation system with a shared water source. The Hendrickson DG41 Backflow Preventer (Atmospheric Vacuum Breaker) is an economical choice to prevent the risk of backflow contamination from outdoor hose faucet connected devices. the DG41 is made of high strength ABS plastic for reliability and durability.Special Notes:During normal operation the backflow preventer will appear to "leak" after the system or timer is turned off. This is normal as the backflow preventer is allowing water to drain from the system without entering the water supply. The amount of water drained will be equal or less than the water capacity of the drip system.This fitting is not designed to be operated under constant pressure. It must be placed after any timers or valves in your system.

  • Apollo 404A33AM Bronze Dual Check Valve with Atmospheric Port, 1/2" NPT Female

    The Apollo DCAP Series Backflow Preventer is designed to protect residential and commercial water supply lines from back-siphonage or back-pressure of non-potable (non-hazardous) substances. It has an intermediate atmospheric vent to insure protection from backflow conditions. It consists of two independently acting and spring-loaded check valves in a corrosion resistant material. During normal flow operation, the vent valve is closed, and the two check valves are open allowing flow of water through the unit. Each check valve is designed to hold at least 1 psi in the direction of flow. When a back-siphonage condition occurs, both check valves close and the atmospheric vent opens to permit air to enter the intermediate zone. In the event of back-pressure and if the second check valve is prevented from closing tightly, leakage will be vented to the atmosphere through the vent port. Economical and durable. Maximum working pressure 175 psig. Approved by ASSE 1012 and CSA. Inlet temperature range 33/210 degrees F. 5 year, domestic warranty. Maximum backflow temperature 250 degrees F. Bronze body. Stainless steel spring. EPDM C.V. Seat Discs. Seats, Spring and seat retainer, and poppets are Glass-Filled PPO. Nitrile/EPDM O-Rings.
