Economy Bottom Drains With Ring Aerator

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 its outlet at the Bottom of the Drain instead of the side of the drain like typical sump bottom drains. 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. Read more

Spindrifter Aerated Bottom Drain

The Spindrifter aerated bottom drain is known worldwide for its quality and design. This Spindrifter aerated bottom drain completely replaces the “Standard Bottom Drain.” The most noticeable feature of the Spindrifter bottom drain is the extra 1 inch DIA Pressure pipe connection in the sump of the drain. 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.
