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.
Tommy Bottom Drains
These Tommy Bottom Drains are perfect for those using mid water feeds to the filter systems and are worried about pulling fish in to the filter, pumps etc.

The Tommy Drain has a removable lid with stainless Steel screws and a flange ring for fitting to liner or concrete ponds.
The Tommy Drain can still be used mounted in the pond base if required, such as for a quarantine system or where the outlet is best suited at the bottom of the drain instead of the side.
The Tommy Bottom Drains are suitable for outlets from the side or bottom of your pond or filter.

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.
