Direct Air Feed Kits Ref: DAF These Direct Air Feed Kits were Primarily designed by Alternative Aquatics to provide an alternative means of getting Air to the Spindrifter Bottom Drain. The Kits are available in all size varients of the rigid pvc pipe used to supply air to the current Spindrifter Aerated Bottom Drains, manufactured by and available from Alternative Aquatics. SpinDrifter Bottom Drain Direct Air Feed Kits let you connect your air pump direct to the Spindrifter Bottom Drain. The Machined direct air feed adaptor simply glues (solvent weld) into the 45° elbow on the inside of the spindrifter bottom drain sump. A short length of air hose connects the nipple on the coned end of the direct feed adaptor to the nipple on the stem of Spindrifter Bottom Drain. The other Direct air feed adaptor conects ( solvent weld ) to the the end of the PVC PRESSURE PIPE that runs from the bottom drain to the airpump. It is reccommended that this PVC PRESSURE PIPE should be terminated as close to the pond as feasible with the straight direct air feed adaptor. The connection from the straight direct air feed adaptor nipple to the air pump valve should be made with flexible Reinforced PVC Hose. Do not use 6mm/4mm airline or multiway valves as this will seriously affect the perfomance of the Bottom Drain and could result in premature failure of your chosen airpump. The bore of the pvc hose should not be less than 3/8 inch(10mm) but may have to be larger if the run to the air pump is a long one. The combination of the Spindrifter Direct Air Feed Kit, the correct bore of the connection hose to the air pump valve and the size of the air pump valve will help to avoid high back pressure on the air pump thereby ensuring a long pump life.
