It is generally accepted that Bottom Drains are a must and should be fitted to all modern day ponds under construction, those being modified, or alterations such as fitting a new liner.
This Standard, but good quality Bottom Drain features a removable lid with screw on flange ring for fitting to liner or concrete ponds.
The Bottom Drain also comes complete with centre pipe, which will need cutting to give the correct gap under the dome once the pond is built. Ideally 20 mm – 25 mm gap is recommended.
This drain comes in two sizes a 50 mm and 110 mm version suitable for standard solvent weld waste pipe work.
The 50 mm Bottom Drain is ideal for quarantine tanks for installation at lowest point of pond or tank, whilst the 110 mm Bottom Drain is ideally suited for ponds and larger quarantine systems. A must for gravity fed systems.
If you require these Bottom Drains to fit pressure pipe you will need the Bottom Drain Converter 110 mm - 4 inch listed above.
