KOITOILET I
The most versatile and complete solution for Koi Ponds using a 4" Aerated Bottom Drain. We have installed this 4 inch bottom drain in our shop display ponds as well as on several 45 mil and gunnite ponds. I used to always say I wouldn't install a pond without a 4 inch bottom drain but I have recently changed that to I wouldn't install a pond without an aerated 4" bottom drain. Remember that aerated bottom drains like the Koitoilet I and Rhino II require an air pump like the Medo Air Pump.
- The Koitoilet I has a sweep type bottom design to eliminate trapping debris.
- 4" of height above horizontal discharge pipe helps to prevent concrete from cracking
- The air supply connection on the Koitoilet I is at the bottom through center column.
- Fully encapsulated screws in large and strong screw bosses protects from cracking and leaks.
- Threaded center column makes for easy disassemble and maintenance of the Koi Toilet I.
- Thick and wide sealing flange for better liner grip.
- Perfect angeled air dome and high quality air diffuser with internal check valve function.
