Dramm Pressure Regulator Valve
About this product
The Dramm Pressure Regulator Valve is located near the pump and discharge hose.
Start-up assembly: Loosen the Pressure Regulator Valve (P.R.V.) by rotating the large red knob on the pump housing counterclockwise. This lifts the spring tension off of the check valve, and allows all of the spray solution to bypass back into the chemical tank via the overflow hose.
