1000 Litre Underdeck Water Tank



1000 Litre Rotoplus Underdeck Water Tank


Dimensions: 1900L x 1800W x 390H

Made from the the same mould as the Rotoplus Slimline tank, we’ve adapted this classic slimline rain water tank to become an under-deck tank. The original inlet is sealed and a new inlet is fitted on the wall as you can see in the image. 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. These tanks have additional powder added, to strength the side walls and increase their wall thickness.

At only 390mm high, this is one of the shallowest underdeck tanks in the market. 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 daisy chain one tank to the next. Like wise with the overflow, we can connect multiple overflows, so you can join overflows on the tank.

Being such shallow tanks, external pumps are required, as your traditional submersible pumps will not fit, nor will they be suitable for the application.
