Spindrifter 1 Inch Direct Air Feed Kit
The Spindrifter Direct Air Feed Kit allows you to hook up your air pump direct to the Diffuser; this means no Airline has to be threaded down the 1″ pressure pipe. This has a number of advantages but the main one is no water can find its way down the 1″ Pressure Pipe, which potentially will hold stagnant water and the dreaded blanketweed.
The Spindrifter bottom drain is known worldwide for its quality and design. The Spindrifter bottom drain completely replaces the “Standard Bottom Drain.”
The most noticeable feature of the Spindrifter bottom drain is the extra connection in the sump of the drain. This is where the machined Direct Air Feed connector glues in, supplying Air to the main diffuser stem. This allows the air supply hose to enter the sump independent of the water outlet pipe, thus eliminating the possibility of restriction to the water flow and somewhere else for blanket weed to attach.
The second part of the Direct Air Feed glues on the end of the 1″ pressure pipe which typically will be located in the filter house, enabling you to connect to the Air Pump.
This Direct Air Kit also prevents any back pressure, causing premature failure on your Air pumps.

Spindrifter Aerated Bottom Drain Twin Inlets
The Spindrifter bottom drain is known worldwide for its quality and design. This unit completely replaces the “Standard Bottom Drain.”
The most noticeable feature is the extra connection in the sump of the drain. This allows the air supply hose to enter the sump independently of the water outlet pipe, thus eliminating the possibility of restriction to the water flow and somewhere else for blanket weed to attach. The membrane and backing plate fit into a recess in the specially manufactured dome (provided). The recess in the dome prevents the membrane from becoming detached. The complete assembly is secured to the bottom drain by means of stem, which also provides the air inlet. Most water pipe sizes can be accommodated, the customer to specify. The air inlet is via a nickel-plated connector.

At Cotswold Koi we understand The importance of pipe work, mistakes made in pipework are one of the most common we come across and can be very costly and hard to change at a later date.
There are three main types of pipe work used on koi ponds:
The use of anything other than pressure pipe and fittings for both gravity and pressure lines is risky, the last thing you want is your bottom drain line leaking after all your hard work building your pond and is only a cost saving exercise, The added security and peace of mind that Pressure Pipe brings is well worth the extra cost. Unfortunately the use of pressure pipe and fittings in the past has simply been too expensive for the majority of Koi keepers, despite it being the preferred choice. here at Cotswold Koi we are looking to bring you a full range of pipe fittings for every occasion.
we are happy to provide assistance, should you need it, please Contact Us if you need assistance in choosing the right pipe work for your project.
