Outlets and overflows are drilled as per your specification or are otherwise supplied as pictured.
The tanks are available in a full range of colours, however dark colours are usually the best to go for when looking at underdeck tanks. Underdeck tanks use more raw material to ensure strength of the tank.
The tank is still made using food grade UV20 Polyethylene and includes one outlet and overflow. If you need to connect multiple tanks, we can add additional outlets so you can connect tanks.
External pumps are most required for underdeck tanks due to the low height. There is a small but powerful submersible pump that is suitable MHR20-TM2 428mm high.
