3400 Litre Tank

The 3400 litre tank is rotationally moulded from high strength polyethylene and complies with EU and UK regulations. Designed with strength in mind, it is shorter in height compared to other tanks on the market today. This means that a shallower hole is needed to accommodate the tank, and this can be by as much as 500mm less. 

The ribbed design provides added strength and efficiency, while also allowing for an environmentally friendly pea-gravel backfill, eliminating the need for a time consuming and high cost concrete base and backfill to be used. The curved element of the design also enables all water, even from the bottom of the tank to be pumped out.

These tanks are amongst the most dependable on the market and as such are supplied with an industry leading 10 year warranty. With the correct installation and general on-going care, these tanks have a long lifetime ahead of them with very little or no maintenance required.

In-Tank Filter with calmed inlet

As standard, a PF filter is pre-installed into the neck of the tank. The filter removes leaves, grit and other debris from the rainwater passing through. The filter requires very little maintenance, usually about 3-4 times each year and is very quick and easy to clean with no consumables, just lift, rinse and replace.

The calmed inlet slows down the speed the water enters the tank and introduces the water into the lower part of the tank. As a result of this controlled entry, the water does not disturb any sediment at the base and replenishes the supply of oxygenated water throughout the tank, not solely at the top. This keeps the water inside the tank fresher for longer.

Submersible Pump

This system is supplied with a P Series stainless steel submersible pump which sits in the bottom of the tank and has sufficient power to service most garden based water requirements such as hoses and irrigation.

The pump combines with a float switch to help protect the pump from running dry and potentially causing damage.

Pump Lifting Chain

This allows you to quickly and easily pull the pump up towards the top of the tank for maintenance or inspection purposes.

Pump Turret

The pump turret is a flexible plastic connection between the pump and access port which allows smooth flow of the pumped water out towards its point of use.

Floating Intake

A floating intake ensures that no water from either the surface or bottom of the tank is taken into the pump. This means that only clean water passes through the system and is pumped to the point of use.

Rodent Guard

The rodent guard protects the water inside the tank from rodents and large debris which could contaminate the water by entering via the overflow.
