This complete 1800 litre direct pressure rainwater harvesting system is ideal for collecting and storing rainwater to use in your home for tasks such as flushing the toilet, washing clothes or washing dishes. The 1800 litre system is suitable for smaller installations such as a 2 bedroom house.
The Direct Pressure system works by supplying water directly to the point of use, for example when a toilet is flushed the pump starts running and rainwater from the tank is pumped to refill the cistern. The pump automatically stops once the pressure in the pipework has been restored. Should the rainwater in your tank reach a low level, a small amount of mains water is sent to the rainwater tank, therefore leaving maximum capacity available for the next rainfall.
This system includes:
- 1800 litre polyethylene tank
- Pedestrian rated telescopic neck and lid
- B Series stainless steel submersible pump with float switch
- Rodent guard
- Calmed inlet drainage pack with rainwater filter
- Pump turret
- Pump lifting chain
- Floating intake
- Automatic mains water top up controller
1800 Litre Tank
The 1800 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.
- 1800 Litre / 400 Gallons capacity
- Made in the UK
- Made from high strength polyethylene
- Ribbed and curved design provides added strength and efficiency
- Low profile means a shallower dig is required
- Large 600mm diameter access allows inspection and maintenance
- Easy to install with environmentally friendly pea gravel backfill
- Ideal for areas with a high water table
- 10 year warranty
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.
Telescopic Neck and Lid
The telescopic neck and lid push fits into the neck of the tank and a rubber seal located towards the bottom ensures a tight fit. The telescopic part of the neck can be extended by up to 300mm and can be tilted in any direction by up to 5 degrees.
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.
This system is supplied with a B 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.
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.
Mains Water Top Up Controller
The top up controller kit detects when the tank water level is running low and initiates a mains top up procedure to ensure the tank never runs out of a water supply.
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.
The rodent guard protects the water inside the tank from rodents and large debris which could contaminate the water by entering via the overflow.
