Drainstore Rainwater Storage Tank Systems

Above Ground Rainwater Storage System

A durable, premium quality garden system for rainwater storage and pumping.The system features a highly efficient rainwater filter-diverter which is installed on the downpipe, cleansing the rainwater before diverting it sideways into the tank while leaves and debris continue down to the drain. When the Rain-Tanks are full the Filter-Collector automatically sends excess rainwater to the drain as usual.

The Filter-Collector’s unique removable filter cartridge can be taken out in seconds for cleaning, allowing maintenance without the need to dismantle anything.

The Rain-Tank System is a practical alternative to underground rainwater systems. Included is a sight gauge, and a self-priming jet pump capable of pumping water to a height of 42 metres. Each tank is 650 litres, a massive 143 gallons. Its attractive modern design has a space saving small footprint. By clever design each tank is easily linked to the next using a sturdy 32mm reinforced hose. Tanks are available in either green or grey granite effect.



System Size Options.

Typical system sizes are 1300 litre (2 tanks), 1950 litre (3 tanks), 2600 litre (4 tanks) and 3250 litre (5 tanks), although any multiple of 650 litres is available.
Systems can then be upgraded at any time with the addition of further tanks.

A Powerful, Fully Automatic Jet Pump

The 3P Rain-Tank system enjoys the pressure and convenience of mains water, thanks to it’s compact and powerful jet pump. The pump’s unique advantage is it’s integrated electronic flow control. Connect it to a hose or tap and it will run when you open the tap and automatically shut off when you close it, so there’s no need to run and switch the pump off. The pump is capable of supplying water at over 4 bar of pressure (59psi) or to a height of 41 metres (134ft). The flow rate through a 1/2 inch hosepipe is similar to mains water. The pump outlet connection will also take a 3/4 inch or 1 inch hose. Attached to the inlet of the pump is a large cartridge filter to ensure only clean water enters the pump. The 3P Rain-Tank System has a compact, sturdy metal valve and a simple, reliable brass connector enabling you to shut off the outlet from the Rain Tank and disconnect the pump for storage.


Pump outlet connection fits 1” (25mm), 3/4” (22mm) and
1/2” (13mm) garden hoses.


Easy-Fit pump connector with shutoff valve
allows easy pump removal.
