Chris and Maries Water Tank Installation Instructions

Important information for any person who currently has a water tank or is
considering purchasing and installing a water tank.

When your water tank becomes full of water it will become very heavy. A 3000L slimline water tank full of water weighs 3 tonnes this is more than the average family car.

If a water tank is not properly installed it can become full of water and fall over. Water tanks, in particular slimlines, must be positioned on a solid level concrete base that it is not concave or convex, dips in or mounds out, or on a base that slopes in any direction, they must be on a solid level concrete base. The slimline tanks must also be positioned 10-15cm (4-6 inches) away from your wall or fence and placed in a position where they will not experience heavy knocks or bumps.

Do not allow children to play on or around your tank. A slimline water tank will swell slightly at the bottom when it is full and a bit more when it is hot.

Your concrete slab needs to be a minimum of 10-15cm (4-6 inches) wider and longer than your water tank and a minimum 10cm (4 inches) thick.
Our water tanks have been computer designed and made locally from the highest tank grade plastics and with proper installation they will provide you with many years of good service.

If you have a plumber install your water tanks please provide them with this information. You should personally ensure that your tanks are being installed correctly as not all plumbers know how to install slimline water tanks correctly.

Common Mistakes

1. Tanks are placed on unlevel pathways around houses or sheds.
These pathways are often running up or down hill and sloped to drain water away from buildings. A small slope will cause the
tank to lean over by several inches (10+cms) and if the tank is installed hard against the wall, when it swells at the base as it becomes full of water and swells a bit more when it is hot, this combination of the tank pressing against the wall and leaning down a slope can cause the tank to fall over.

2. Tanks are placed on too small a slab with tank installed hard against wall with no room to expand.

3. Tanks placed on uneven ground, pavers, soil, sand, pebbles, gravel, garden beds.
None of these surfaces are strong enough to support a slimline water tank.

4. Tanks are positioned by eye.
Use a spirit level to position your water tank, don't use your eyes in place of a spirit level. A small slope on the ground will be magnified into a large lean on the tank, you need to use a spirit level to check the ground.

Tank Safety Check

Doing a tank safety check is easy;

Place a spirit level on the side of your tank to see if it is standing upright and not leaning. If it is leaning drain the water out, disconnect the tank and create a proper level base. Check your tank level again when it is full of water.

See that your tank is standing on a suitable concrete base with enough clearance between the tank and the wall.
