Dramm's Syphonject draws a concentrated solution from a bucket through a flexible suction tube and then dilutes it with the passing water stream at an approximate ratio of 20 parts water to 1 part concentrated solution. Includes a 170PL nozzle - ideal when using fertilizer syphons.
Dramm recommends that you determine the exact dilution ratio of your Syphonject with your available water pressure, hose and choice of nozzles. The 20:1 dilution ratio is directly related to the amount of water pressure available through your garden hose. As water pressure increases, the dilution ratio will increase.
