Water pump flow control connector

Water pump flow control connector with relief valve. Position of the side screw allows setting the desired flow level safely, without blocking the flow, which might damage the pump. External thread's dimensions (12.7 mm / 1.25 mm) fit the MOSFiATA submersible pump (25W turned out to be an overkill for my homemade hydroponic system). The hose connector is tight enough for an 18 mm internal diameter.
