For irrigation, we have about more than 50000 L of large tank and the outlet of 2 inches (thick red - high pressure) goes through the ground for drip irrigation. Now I need another small tank of 200 L with some liquid(nutrient for soil) to be added along with water. Though the outlet of tank B will be 1/2 inch, the water pressure(in drops) will be control using a gate value. Since the existing water flow is very high pressure, just directly connecting the outlet from tank B to the existing water pipe may result in water being pumped into tank B.
Though in picture, the position of the outlets are in middle, actually it will be in bottom.
Will check valve be the solution here? Since the outlet flow from tank B will be drops and the from tank A it will be very high pressure, could the valve open so that those drops will get mixed with existing water flow?
If check valve is not the right one what should use here?
