An easy and economical way to  automate a Blumat and/or BluSoak system. Just attach this to a 24/7 garden hose and gravity will take care of the rest. 

For small systems, this is a simple way of controlling your pressure without needing an expensive pressure regulator - just make the reservoir higher for more water, lower for less. 

The included fittings give you a choice of connecting to your water supply line with either a 1/2" male pipe thread or a 3/4" FHT

If your water source has over 50 psi pressure, add this (or similar) high quality but inexpensive pressure reducer: IG16309.
