DIG’s two-in-one, 3/4” and 1” Filter/Pressure Regulator combines a 150-mesh stainless steel filter with a 25-PSI or 45-PSI pressure regulator, reducing the number of components needed to start a drip irrigation zone. The heavy-duty filter/pressure regulator’s compact design fits in smaller sized areas allowing several drip zones inside an irrigation box. For best results install it upstream of the control valve for reliable operation and easy maintenance of a drip irrigation zone.
