Poly Tank Installation Guide

IMPORTANT! Incorrect installation will void your warranty.

Site Preparation: The site must be firm, level, stable ground. It must be at least 600mm greater in diameter than the tank. The base must be adequately and uniformly supported over its whole area. Do not place the tank on beams with interval spaces. Ensure that the area is free from any sharp objects such as stones or roots. A concrete pad or 100mm deep compacted sand is recommended and must also be 600mm greater in diameter than the tank. If using sand it must be boxed in with appropriate material to avoid erosion. If locating the tank on a sloping section make sure that the area will not erode and do not backfill against the tank.

The tank is not to be buried. Do not walk or put weight on the dome of the tank this is unsafe and could also damage the tank.

Plumbing: a BSP outlet is fitted to the base of the tank ready for you to screw in your fittings, a reducing bush / nipple can be fitted if required.

No extra penetrations are to be cut into the sidewalls of the tank without written consent from the manufacturer. No penetrations are to be cut into the base.

A specially moulded box with flat sides is conveniently located to the front of the inspection hatch at the top of the tank. All fittings: inlet, overflow, ballcock, water level indicator etc. should be installed here. Therefore it is not necessary to walk on the dome. Connection between the tank and pump must include a flexible hose (not polyethylene pipe) to absorb vibration.

If connecting multiple tanks together or connecting a tank to a rigid structure, flexible hose must be used or a 90-degree loop to allow for expansion or shrinkages. Pipe the overflow away from the foundation to prevent erosion.

The cap in the middle of the dome is used during manufacture and must not be used for installation. Do not remove this cap. The lid is vented and offset for ease of inspection. PLEASE NOTE a 22,500 litre tank weighs 22,500 kilos when it is full so take care with preparation of the site and the installation of the tank.

Authorised TANKMAKERS agents may in certain circumstances deviate from these conditions if approved by TANKMAKERS.
