A Backflow Prevention Valve is required to stop water from the irrigation system returning to the potable supply.
Once you have this kit your garden tap can be removed, the backflow prevention kit can be installed and the garden tap installed back into the backflow prevention kit.
That way your irrigation system is not restricted by the reduced flow rate of a garden tap and you still retain the tap to attach a garden hose to if needed.
This back flow prevention kit includes:
- 1 x 3/4" Dual Check Valve
- 1 x 3/4" Brass Ball Valve MF
- 2 x 3/4" Brass Nipples
- 1 x 3/4" Brass Threaded Tee
* Teflon tape is required for assembly.
