Water Tank dimensions and specifications
The main dimensions of the plastic water tanks can be found on the product page under the 'Specifications' tab. Dimensions such as length, width and height are given in cm. The height is generally the height of the tank without the lid opening. For more precise details such as LxWxH in mm, height including lid, the exact position of the brass BSP outlet or the position of the integrated baffles or ribs etc., please refer to the technical drawings of the water tanks. These can be found on each product page under the 'Drawings and Certificates' tab.
Here you will also find a resistance list, which shows the material resistance to specific liquids or chemicals that can be stored in our plastic water tanks. Permanent storage and use of water in our water tanks is possible up to a temperature of 70 degrees Celsius. The storage of diesel is also no problem. The WRAS certificate confirms that the water tank is suitable for the storage of drinking water. If you are a business customer, we can also provide you with 3D models of the water tanks in the form of CAD/step files for your individual planning.

Easy installation of Tank accessories on the Water Tank / threaded BSP outlets
All water tanks have a moulded inch size brass threaded BSP outlet. Here you can install our Brass Tank Connection Sets or other brass accessories. In this case, order the brass threaded BSP outlet on the water tank open/drilled to drain the liquid and empty the water tank.
If you purchase the water tank with an 'undrilled/closed' threaded BSP outlet, the threaded BSP outlet will still be on the water tank but will be completely covered in plastic from the inside. This means that the filling medium never comes into contact with the brass thread. The plastic water tank is therefore also ideal for the safe storage of liquids such as chemicals, alkalis or acids that should not come into contact with brass.

Equip the Water Tank with individual and additional Tank Connections
Install Push-In BSP Fittings on our Water Tanks
If you need to install additional or alternative connections at points on our water tanks that are difficult or impossible to access through the existing lid opening, we offer a convenient and flexible solution with our new Push-In BSP Fittings. The Push-In BSP Fittings can be installed completely from the outside at any flat spot. This gives you an external thread of ½ - 2 inches on the water tank. You can then screw other required tank accessories (preferably plastic) onto the external thread of the Push-In BSP Fitting.
If you are storing liquids other than water in the tank, we can also supply the Push-In BSP Fittings with an NBR (diesel resistant) or FPM (chemical resistant) gaskets. For more information on sizes and installation on the water tank, click on the button below the video or view the video.
Install PVC Connections / PVC Tank Connection Sets on our Water Tanks
Any additional connections required for inlet, overflow or external ventilation can be made easily and independently using PVC Connections or PVC Tank Connection Sets in sizes ¾ - 2 inches. Ensure that the point where you want to drill a connection hole is accessible through the existing lid opening on the water tank so that the PVC Connection can be screwed on tightly.
This will provide you with an external thread in the required inch size for the installation of other tank accessories such as ball valves or hose tails. For more information on available sizes and installation, click on the button below the video or view the video.
Buy a Water Tank with pre-installed Spin Weld Outlets (LLDPE) - exclusively for business customers
If you do not want to install the Tank Connections yourself we offer Spin Weld Outlets for all natural translucent and in colour-configurable Water Tanks. On these you can install your required tank accessories.
You are free to choose the position and size (available in 1/2 - 2 inches) of the Spin Weld Outlets you require, but please note that the Spin Weld Outlets can only be welded into flat areas of the water tanks.
