Reo Sac FAQ
What is the difference between reo sac™ and other reinforced bladders?
The reo sac is superior to other reinforced bladder tanks in the following ways:
- it has the unique steel mounting plate that ensures there is no movement in the fixed PVC pipe work
- the unique mounting plate not only fixes the pipe work in place but it ensures that there is no stress or pressure on the pipe work
- the standard inlet fitting is 100mm PVC - the same as everyday normal PVC pipe work that you will have on the side of your house. In case you only have 90mm pipe work, a 100mm-90mm reducer is included as standard in the kit. Or you can use an adaptor if you have rectangular or metal down pipes. Most other reinforced bladder brands supply only a small diameter tank fitting (normally 50mm) which reduces the flow rate into the bladder tank during a high rainfall event. The combination of the large inlet fitting and the unique steel mounting plate allows multiple bladder tanks to be connected together via a 100mm manifold to maximise the fill rate and ensure multiple bladder tanks fill and empty as one large tank.
- Each and every reo sac is tested in the factory before it leaves carrying its own unique serial number which is tracked from its initial fabrication through to its final installation (as long as you send us your warranty registration form or register on our website so we know where it is!)
- reo sac has its own sales team that is available in all eastern seaboard cities to follow up on any installation issues, warranty claims or concerns relating to the product
- reo sac has a national network of preferred installers who can provide you with an obligation free quote for the supply and installation of a reo sac bladder tank
- the reo sac comes standard with a 25mm air vent with mosquito protection to ensure any air entering the bladder tank can easily escape without placing any pressure on the bladder tank itself. This air vent is 67% larger than most other brands meaning there is no risk of undue pressure being placed on your bladder tank by air trying to escape during a rapid fill in heavy rain.
What is the difference between eco sac® and reo sac™
The eco sac is installed inside a steel frame which provides greater peace of mind that the water you capture and store will stay within the exact location you want it to. The eco sac will also store approximately 20% more water for the space it takes up on the ground because the flexible PVC material fills the frame and harness and takes on a square shape within the framework. The eco sac also has a full range of protective covers available.
The reo sac does not require a frame due to the reinforced nature of the material. It has the same inlet and outlet configuration as the eco sac® with the same unique mounting plate. However, the absolute location and footprint size of a filled reo sac cannot be guaranteed (this is the same for all reinforced bladder tanks) as it can with the eco sac®. reo sac holds less water than the eco sac® due to the non-flexible characteristics of the material.
What is the size of the reo sac™ box?
Because of the small frame required to supporting the unique steel mounting plate, the box for the reo sac bladder tank is relatively small and can easily fit in the boot of most cars. Its measures 380mm W x 480mm H x 900mm L
How much storage do I need?
The answer depends on two things:
- How big your roof is to capture the rainfall that you need?
- What you want to use the water for?
Call New Water (NZ) Ltd on Toll Free 0800 4 NEW WATER and we will help you determine how much storage you need in order to have enough water for all the things you want to use it for. Remember that 1mm of rain on 1 square metre of roof will give you 1ml of water.
What colour is it? Does it come in other colours?
The reo sac colour is grey. It is only available in one colour due to the highly specialised nature of the material.
What do I get in my reo sac™ kit?
With every kit you get:
- the bladder with 100mm inlet and 2 x 32mm outlets fitted
- Steel mounting plate for inlet and outlets with a supporting frame
- protective geo textile fabric ground sheet
- 2 ball valves
- screws and brass locking nuts
- 300mm length of 25mm vent pipe with mosquito protection
- 1 x 100mm-90mm reducer
- 1 overflow relief valve
- a pump (optional)
Will the reo sac™ leak?
No. reo sac is manufactured using industrial strength reinforced fabric sealed by high frequency welding. The reo sac manufacturing technology is taken from much larger industrial applications for bladders holding over 100,000 litres of fluids much heavier than water. reo sac uses the overlap method of welding the seams which is much stronger than the fusion method used by most other brands.
What about difficult access under my house or deck?
A reo sac flexible rainwater storage system will fit under your house as long as a person can get under your house. Ideally, a height of at least 700mm is preferred as it will enable maximum storage capacity for your reo sac. The sac will fill to a height of 600mm except for the narrower widths that only fill to 500mm (refer to the size and capacity chart)
If space is tight, the overflow pipe can be set lower than 600mm. The height of the overflow pipe from the base of the bladder tank will determine the height to which the reo sac fills.
Can a pump be connected?
Yes. Any type of pump and/or mains-water control system can be connected to your reo sac flexible rainwater storage system.
If you want to reticulate inside the house for toilet or washing machine you will need to buy a float chamber to connect the mains water controller to the reo sac so that the controller knows when the reo sac is empty and to switch back to mains water. If you order the pump from us then the float chamber is automatically included free of charge.
Can it overfill?
Not if the reo sac is installed according to the installation instructions! Our preferred professional installer network is properly trained to ensure that the reo sac will never overfill. It is essential that the overflow pipe be set correctly at no more than 600mm from the ground.
Once the bladder is full, any excess rain will divert to the existing stormwater system. The reo sac includes a fail-safe relief point for the overflow pipe unlike any other flexible or fixed rainwater storage system.
Does the reo sac™ need to sit on level ground?
Yes. The ground under a reo sac cannot be sloping. It needs to sit on level ground in order to ensure that maximum storage is achieved (water won't run uphill!) and to remove the possibility of the bladder tank moving when filling. However you do not need to prepare the ground with concrete. The bare earth is sufficient just as long as long as it is cleared free of any sharp objects and the provided geo-tech ground sheet is used.
How good is the water quality?
Does the reo sac™ come with a warranty?
Yes. The reo sac has a 10 year warranty as long as it is installed by a trade professional in accordance with the installation instructions You can even register your warranty on line. (See our Warranty Registration page)
What sizes does the reo sac™ come in?
reo sac® comes in 66 different sizes and configurations ranging from 1,150 litres to 7,050 litres in a single bladder tank. More storage can be achieved by joining multiple bladder tanks together as long as you have the space available.
What can I use the water for?
The water stored in a reo sac can be used to water the garden, fill swimming pools or fishponds or can be reticulated back into the house for use in toilets or washing machines. Our installers can advise on what size reo sac is best to meet your water usage needs and also what pump is best for your needs.
How much does the reo sac™ cost?
The reo sac price depends on the size you buy and whether or not you buy a pump. Call us on Toll Free 0800 4 NEW WATER and we will organise for a qualified installer to come and give you an obligation free quote on the reo sacthat best meets your needs and its installation or refer you to one of our national resellers.
What happens if I move house?
The reo sac is easily transportable so that if you move house you can simply empty the reo sac, roll it up and dismantle the mounting plate and frame and all the connections. As long as the reo sac will fit between the piers of your new house you can move it with all your other possessions and get a qualified installer to re-install it for you.
