Nylex Water Tanks FAQ's

1. How do I choose a location for my tank?
There are many factors that will determine the most appropriate location of your rainwater tank. Nylex recommends that you walk around your house and note the locations of your downpipes.

The closer the tank is to a downpipe, the simpler and cheaper the installation will be. Once you have selected an appropriate site, you can begin to prepare this site for the tank.

2. How much water will I collect?
The amount of rainwater you will collect is dependant on a number of factors, including:

* The size of your roof – including pitch and shape.
* The amount of rainfall you experience in your area.
* The number of down pipes you have leading into the tank.

For every millimetre of rain on 1m2 of your roof, you will collect 1 litre of water.

To determine the amount of water you will be likely to collect, please refer to “Selecting the Right Tank for Your Home”.

3. What do I get with my tank?
If you purchase a round rainwater tank, you will receive a tap / gate valve, an inlet with strainer and an overflow.

If you purchase a slimline / rectangular rainwater tank, you will receive two brass outlets, a tap / gate valve, an inlet with strainer and an overflow.

Please Note:
? 600 Litre Slimline Tanks are supplied with 2 x 20mm brass outlets, 2 x 50mm brass threads (moulded into the tank), 1 x 20mm tap, 1 x 50mm overflow and 2 x plugs to seal the unused ends.
? 1100, 1600 and 2100 Litre Slimline Tanks are supplied with 2 x 25mm brass outlets (one at the base and the other at 400mm - bucket height) and 1 x 90mm overflow. Overflows can be positioned between 2 and 10 or 4 and 8 o’clock. Outlets can only be positioned at 2, 4, 8 or 10 o’clock.

5. Are there any regulations I need to follow when installing my tank?
Nylex recommends that you check the relevant regulations relating to rainwater tank installation with your local council.

6. Who can install my tank?
Nylex recommends that your tank is installed by a licensed plumber.

7. What rebates are available for my tank?
The rebates available depend on the state in which you live:

* 2000L – 3999L Tank = $150
* 4000L – 6999L Tank = $400
* 7000L + Tank = $500
* Internal Connection = $150

Victoria:

Please Note
The Internal Connection refers to connecting your tank to a part of your homes water supply. For example, using a Rainflush System to provide water to flush your toilet. Conditions apply to all rebates listed. Current as at 26/10/04.

8. How do I apply for the government rebate?
Before you can apply for the government rebate, you need to:

* Keep your purchase receipt.
* Have your plumber provide you with a certificate of compliance once the tank is installed.

Once you have completed these two items, contact your local water authority and request that they send you a rebate application form to complete. You will be required to provide your water authority with the purchase receipt and certificate of compliance.

9. Can I drink the water from my tank?
Nylex recommends that you do not drink the water from your tank.

10. What is the best way to use my stored rainwater?
The most effective way to use rainwater is to use it to flush your toilet. On average, 19% of the potable water supplied to your house is used to flush the toilet.

By using a Rainflush System to flush your toilet, you will make maximum use of your rainwater whilst reducing the demands you place on fresh drinking water.

11. How can I divert the stored water to flush my toilet or use in my washing machine?
The use of a Nylex Rainflush System will provide you with this capability.

The Rainflush System provides you with a continuous and pressurised water supply. The system will use your tank water and divert to the mains if the supply of tank water runs out.

* 50 litres per minute (single storey homes)
* 60 litres per minute (double storey homes).

12. How much water does my garden require?
Depending on the size of your garden and if you also wanted to water your lawn with your rainwater, you will need the following amount of water per day:

13. Why is a slimline tank more expensive than a traditional round tank?
The cost of a rainwater tank is based on the raw materials that are used in the manufacturing process. All Nylex rainwater tanks are manufactured from polyethylene. Approximately 80% more polyethylene resin is required to manufacture a slimline tank than a round tank.

Slimline tanks require a larger amount of resin to create a thicker wall that will not bubble out when the head (water) pressure grows in the unit as it fills. Round tanks do not need as much resin as they allowing the head (water) pressure to be more evenly distributed.

14. Is it cheaper for me to buy more than one tank?
Nylex provides discounts on the purchase of 22,700L, 30,000L, 35,000L, 45,400L and 47,200L combinations (minimum purchase of 2 tanks for each of these sizes).

15. How do I connect one tank to another?
Two tanks can be connected together via a balance pipe. Nylex recommends that this is done by a licensed plumber.

16. How long is the warranty on my tank?
Nylex provide a full 10 year unlimited warranty on our entire range of tanks.

17. Can I bury my tank underground?
Nylex recommends that you bury up to one third of the wall height. Any more than this will void your warranty.

18. What base do I need to prepare for my tank?
You can place your tank on a bed of sand, a concrete slab or a tank stand:

* Sand - A 7-10cm sand bed is an ideal base. Ensure the sand bed is 30cm wider than the diameter of the tank and that the sand cannot be eroded from under the tank. ie. direct overflow away from the tank.
* Concrete - Tank may be sited on a level concrete slab slightly wider than the diameter of the tank.
* Stand - Only tank stands with a hardwood decking spaced no more than 5cm apart should be used. Bearers must have sufficient strength to prevent deflection when tank is full.

19. What is the height of a tank stand?
A tank stand is 600mm high and at the base is 100mm wider than the tank.

20. What pump do I need for my house?
The pump you may need depends on the number of people in your house and what you intend to use the pump for.

Nylex can provide you with a range of pumps to assist you in dispersing your stored water in and around your home. Pump options include:

* Low Volume Pressure Pumps to service 2 taps.
* Pressure Pumps for small (3 taps), medium (4 taps) and large (5-6 taps) homes.
* High Volume Pressure Pumps to service 7 taps.
* Transfer Pumps – to move stored water from one location to another.
* Submersible Pumps – to place inside your stored water supply.

To determine the amount of taps your pump will need to service for your home, allow one tap per person in your household plus two taps.

For example:
2 person household = 2 taps + 2 taps (for washing machine & dishwasher) = 4 taps
3 person household = 3 taps + 2 taps (for washing machine & dishwasher) = 5 taps
4 person household = 4 taps + 2 taps (for washing machine & dishwasher) = 6 taps
5 person household = 5 taps + 2 taps (for washing machine & dishwasher) = 7 taps

21. Will my tank be delivered to me free of charge?

* 100L – 8,208L tanks will be delivered to your tank outlet.

22. How long will I have to wait for my tank to be delivered?
