Installing your tank

Installing Your Home Tank

Rain water tank installation is critical to the effectiveness of your Home Tank and it is important this guide is followed to ensure a long life for your tanks. If this guide is not followed then Aquadam guarantee may be voided.

Tank Installation Steps

Above Ground:

Steps 1-3 on pad

1) Prepare a reinforced concrete pad that is level and 300 mm wider than the diameter of tank OR prepare an earth ring 300mm wider than the diameter of the tank so that no part of the tank is bearing on the wall. Fill is to be consolidated fill with 50-75mm of sand or crusher dust on surface.
2) Tank is rolled to position (if position requires a crane this will be at purchaser’s expense).
3) Tank must be secured or water filled to 25mm to prevent blow-away (no responsibility taken for tanks being damaged in this manner).
…go to steps 4 – 6.

Steps 1-3 on stand

1) Prepare a stand that has hardwood decking with gaps no grater than 25mm (1”). Decking should be supported structurally by bearers strong enough to prevent sagging of decking when tank is full.
2) Tank must be lifted into place by crane (if positioning requires a crane this will be at purchaser’s expense).
3) Tank must be secured or water filled to 25mm to prevent blow-away (no responsibility taken for tanks being damaged in this manner).
…go to steps 4 – 6.

Steps 4-6 on pad or on stand

4) Water Inlet – Water should be directed into tank through the strainer. Fixed inlets must be suported and have flexible hose fitted (similar to outlet instructions). Inlet pipe must be supported by stand.
5) Water Outlet – Connect your outlet with flexible hose 300mm in length. The hose must be placed between the valve and all other plumbing or rigid pipe work. Elbow fittings must be used as shown (important: Water capacity of the inlet must equal water capacity of the overflow e.g. 2 x 100mm inlets = same capacity overflow).
6) Water Outlet – Overflow – Connect overflow. Water must be piped away from the tank.

In Ground:

1) Before commencing, check for underground pipes and ensure excavation work does not infringe on the weight bearing capacity of adjacent structures.  Excavate the hole in depth to allow for 50-75mm of bedding material and a maximum depth of 1/3 of the tank wall height. Excavate the hole in diameter to allow for a 150-200mm gap between the tank wall and the surrounding soil (the site is not suitable if there is water or if the floor of the hole is unstable). Spread washed river sand into the hole and compact it with a plate compactor, to provide a firm level base. Check that no rocks, roots or sharp objects penetrate the sand base.

2) Tank must be lowered into the hole squarely by crane (if positioning requires a crane this will be at purchaser’s expense).

3) Prior to starting to backfill, the tank must be filled with water to a level marginally above ground height. The soil taken from the hole must not be used as the backfill under any circumstances.  Spread a 200 -300mm layer of sand around the base of the tank. Manually compact the sand ensuring that all the voids are filled. Continue adding sand in 200-300mm layers, ensuring each time that it is well compacted into all areas until it comes to within 150mm of the surface. Restore remaining 150mm with fresh soil.

4) Water Inlet – water should be directed into tank through the strainer. Fixed inlets must be supported and have flexible hose fitted (similar to outlet instructions). Inlet pipe hose must be supported by stand.

5) Water Outlet – connect your outlet with flexible hose 300mm  in length. The hose must be placed between the valve and all other plumbing or rigid pipe work. Elbow fittings must be used as shown (important: Water capacity of the inlet must equal water capacity of the overflow e.g. 2 x 50mm inlets = same capacity overflow).

6) Water Outlet – Overflow – connect overflow. Water must be piped away from the tank.

Home Tank Checklist

On-site delivery

– Check you’re prepared for our driver to position tank, drill outlets, fit taps & seal.
– Check there is suitable and safe site access (see preparing for delivery).
– Site must be prepared as per instructions.
– Make sure is about 4 people are present to assist tank positioning
– Water is immediately available to put 25mm in tank to prevent blow-away.

Preparing for Delivery

This Easy Step Installation Guide will help you prepare for the arrival of your new Home Tank.

Delivery & Safe Access

To deliver your tank without damage please ensure that you notify logistics if there is not sufficient space for an oversize semi-trailer to around or if there are any obstacles that the driver will need to consider. (A minimum of 50m turning space is required, max dimensions of truck: 21m(L) x 2.5m(W) x 5.2m(H). Obstacles may include low power lines, gates, inaccessible roads, roundabouts, crossings, overhanging trees etc. Check our website to see our delivery areas). Our driver will need assistance at time of delivery to unload your tank from the truck. Please have able-bodied people available., if assistance cannot be provided then hire or use of any equipment is at purchaser’s expense (i.e.crane hire, 4WD tractor, backhoe hire, front end loader hire).

Delivery Onsite

Onsite delivery is where our driver will help site the tank only if the provided conditions are met as per the Checklist., if you have followed the guidelines, the site is prepared and safe, our driver will install your tank.

Plumbing Fittings

Please advise prior to delivery if you need any extra Home Tank fittings or valves. Extra fittings are available upon request at additional cost. Check with local council for regulations relating to rain water tank installations. See fittings & accessories for more information.  Typical PVC or metal fittings are relatively rigid and inflexible. (Purchase and delivery of any additional plumbing fittings and pipes are responsibility of purchaser. Our guarantee specifies a 300mm flexible hose be fitted to the outlet).

Securing your tank

When your tank arrives you must put at least 25mm of water into the tank. If water is not available ensure that the tank is tied down to secure it from blow-away and damage (Aquadam take no responsibility for tanks being damaged if the tank is not secured properly). Water tank stands can be used but must be designed by a qualified consulting engineer (due to OH&S our drivers and service people are not permitted to work at heights and therefore cannot assist in placing or servicing tanks on stands).
