Help & FAQ's

  • What is Hydrowall?
    Hydrowall is a structural building system that will contain water inside the wall. Hydrowall is a standalone building frame system. It can be used instead of, or alongside traditional construction methods like brickwork, or stud frame. Hydrowall is a modular system and is available in a range of heights, lengths, and widths. Hydrowall is quick and easy to assemble. The modular components simply connect together to create wall sections Hydrowall can be covered with whatever cladding system you choose so that it matches in with the rest of your home
  • Can I use Hydrowall for Structural load- bearing applications?
    Yes. Hydrowall is designed to support roof loads. The standard system can support roof loads in most domestic situations. Each design must be checked and certified by engineers for structural use. Superwall Systems can arrange for engineering drawings to be completed for your design. Sample engineering drawings are available upon request
  • an I put services like electricity and water in the Hydrowall
    Yes. Service conduits can easily be incorporated in the Hydrowall System. It is best to install services prior to cladding. Services can also be surface mounted providing the is secured to the wall only in the designated safe places. Please refer to the spacing diagram in the Hydrowall Installtion manual for location of the frame components
  • What are the dimensions of the Hydrowall?
    Hydrowall is a modular system. Modules are available in a range of heights, lengths and widths as follows: Heights: 1800mm, 2100mm, 2400mm, 2700mm and 3000mm Lengths: 685 (600) mm and 1285 (1200)mm Widths: 300mm, more to come Custom sizes may be available on request
  • Can I have windows, doors or openings?"
    Yes. Modules are connected together with a flexible pipe. The pipe can be as long as you want. Windows are easy because usually the pipe can run in the cavity under the window. Doors require that the pipe goes under the door somehow. Either down through the slab or under the door frame. Please refer to the technical drawings for door and window details.
  • Can I use it as a retaining wall?
    Not at the moment sorry. It's something we are working on
  • Can I hang a painting on the Hydrowall?
    Yes. Hydrowall is similar to stud frame construction. There are parts of the frame that are safe to drill into without damaging the liner, but parts that are not safe. Use the spacing diagram in the installation manual to check where the frame, or use a studfinder. If the fixing misses the frame then there is a risk that it will pentrate the liner and cause a leak. It is best not to drill into the wall unless you are SURE there is frame behind it. The vertical posts are the safest place to drill. There are also a number of hanging products like 3M adhesive hooks, or picture rails located near the cornice that can be used.
  • What happens if it gets a leak?
    The Liner is made from a heavy duty reinforced material, similar to that used for inflatable dinghies. It can withstand a lot of pressure and abrasion and each liner is pressure tested when it is made so it is very unlikely that it will leak from any fault or wear and tear. The Hydrowall system also incorporates a flexible ground mat that acts like a flashing to drain any water to the outside. There are other reasons that the tank may leak as follows: 1. Punctures Punctures are likely to occur if someone drills, screws or nails into the wall at an unsafe position. The safe positions are the vertical posts or high up the wall above the water line. The other cause of punctures is if someone has drill or screwed into the metal frame and created metal shards. These can find there way under the liner and may puncture the liner. It may not happen immediately but as the tank moves through filling and emptying, the metal shard could work its way under and into the liner. Fixing punctures Like an inflatable boat, punctures can be repaired if required. This will usually involve removing the cladding around the leak and draining the liner to below the leak level. You can use an inspection camera to help locate the leak (most plumbers will have one). If it is not possible to repair the leak then the leaking unit can be bypassed altogether but connecting the adjacent Hydrowall modules together. If the leak is high then another option is to only fill the Hydrowall to just below the leak level. This can be done by adding an upstand pipe at the outlet to create an overflow at the desired level. The upstand pipe needs to be just below the leak level. Then when the tank fills it will overflow before it reaches the leak level 2. Plumbing leaks Leaks can occur of the outlets are not connected properly. Always use high quality hose clamps and ensure they are tightened. 3. Overflow leaks If the inlet cap is not tightened then water may overflow. Always tighten the inlet caps on any that are not being used.
  • How do I clean the tank?
    Prevention is better than cure, so we recommend using a Superhead or some other filter to prevent debris and pollution getting inside the tanks (liners). If you already have a problem with debris in the tank then it may be difficult to fix due to the limited access. Most debris is located closest to the inlet(s). If you have a severe silt problem then you can try to vacuum it up by inserting a suction hose into the inlet. If you need to treat the water for smells or discolouration then you can try a treatment solution. Most caravan or boat shops will sell chemicals used to treat storage tanks. If that fails then you may need to drain the tanks.
  • Can I drink the water?
    Hydrowall is available in 2 types: Standard and potable. The Standard Grade is made from reinforced PVC which is not recommended for drinking (potable) water. This type is our economical option and is suitable for applications where drinking water is not required. The Potable Grade liner is made from TPU and is suitable for potable water. The material has been certified and is Watermark approved. NOTE: It is important to routinely check the quality of the water stored in the tank. Other factors like pollution and debris, mosquitoes and sunlight can affect the water and make it unfit for consumption, regardless of the liner used. We recommend the use of a UV steriliser or other filter on the outlet where water will be consumed.
  • What colours are available?
    Any colour! The Hydrowall System consists of a frame and flexible liner to hold the water. It can then be covered in whatever cladding you choose. Some common cladding materials are: Colorbond/ Metal Cladding- A range of colours and profiles are available Fibre Cement sheet (or similar)- Can be painted as required, or tiled Weatherboard- Timber, or composite boards can be used. Please visit the photo gallery for some examples and check the technical drawings for installation instructions.
  • Can I join the modules at angles other than 90°?
    Yes- almost anything is possible but keep in mind the standard connection system is for 90° connections. Other angles will usually require customisation of the joining parts and/ or spacing members to create the non- standard connection.
  • Warranty and Product Lifespan Information
    Hydrowall has a lifespan of 25+ years. Hydrowall has a 2 year product warranty to be free from faults and defects. Each liner is individually tested checked during manufacturing and quality control prior to shipping. If for some reason the liner appears to be damaged then please contact us to arrange a replacement.
  • Can I use it in Freezing Climates?
    Yes- If it is insulated. Water has a a high thermal mass so it will retain the thermal energy that it gains from the internal or external environment. If you are in a freezing climate it could be used as an internal wall and insulated from the outside air temp. Then it would heat up from any internal heating and retain and maintain the temperature inside the room. The water itself can be heated (from solar or whatever) and become a heat source. It is the same theory in hot climates too. The recommended construction is to insulate the wall on the outside and use the water (thermal mass) to help regulate the internal temp. If however it was a standalone wall like in a shed or fence then it is likely to freeze.
  • Why Do I Need a First- Flush Filter?
    A first flush filter prevents pollution entering the rainwater tank. This prevents sediment and pollution from building up in the rainwater tank. Pollution and sediment in the tank can create a number of potential problems ranging from wear and tear on pumps and appliances to hazardous health issues from bird droppings and rotting leaves.
  • Are there distributors in Canada or USA?
    The Superhead fits 90mm (OD) pipe, while 3 inch pipe has a outside diameter of 88.9mm. It is a close fit and can be sealed with silicone, or if you can source 90mm pipe then it will also fit.
  • Does it fit USA pipe sizes?
    Yes. Australia uses 90mm (outside diameter) pipe for stormwater. USA uses 3" pipe which has an outside diameter of 88.9mm. It is a very close fit and the fittings are tapered to fit the smaller pipe size. It can easily be sealed with pipe cement or silicone. It is not high pressure so the slight size variation is not a problem
  • How Does Superhead Work?
    It is best to watch the video to see how it works, but here is the basic explanation: When it first starts to rain, water contaminated with leaves, dust, bacteria, salt and other pollution is washed off the roof and into your downpipes. The Superhead is positioned between the rainwater tank and the gutters so instead of the contaminated water entering the rainwater tank, it fills the flush pipe. After about 20- 30 litres of water has been flushed off the roof it should be clean (depending on the roof size). The water will then automatically divert into the rainwater tank. The flush pipe slowly empties so it is ready for next time it rains.
  • How much does it cost?
    The Superhead costs around $70. You will also need to buy a length of PVC pipe to create the flush pipe and connect to the Rainwater Tank. Buying the various components invidividually will cost over $100
  • What is a Rain Head and First- Flush Filter?
    A rain head is a device which is positioned on the top of downpipes to stop leaves and large debris clogging up the stormwater system. A first- flush is a filtration device which filters smaller debris from the rainwater harvesting system by discarding a preset amount of water when it first starts to rain. When the flush has been done the water is diverted into the rainwater tank The Superhead combines both devices into one simple and compact design.
  • What is size first- flush pipe do I need?
    The volume will depend on the length of the pipe. 90mm pipe has a volume of 7 litres per metre. A larger diameter pipe can be used to increase the flush volume with the use of adapters. The flush volume can also be changed using the adjustable valve at the bottom of the first- flush pipe. For large roofs we recommend installing a Superhead on each downpipe to ensure an adequate first flush.
  • How do I connect it to standard reticulation fittings?
    The adjustable drain can be replaced with standard reticulation fittings so that the flush water can be piped to a different location. To do this you will need the following fittings: length of 19mm pipe (or adapters to reduce to the desired size) 19mm male screw- barb (male screw on one end- barb fitting on the other) 19mm valve ( a cheap one will do and is available in most reticulation sections/ stores) Method: Remove the adjustable plug and insert the male screw- barb fitting. Attach a length of 19mm pipe to the barbed end of the fitting. Cut the pipe to the desired length and attach the valve to the end of the pipe. Calibration: Close the valve and fill the flush pipe with some water (or wait until it rains). Open the valve gradually until it drips a few times per second. Maintenance: There is an increased chance that the valve will become clogged with fine debris from the flush pipe so care should be taken to check that the valve is dripping and emptying the flush pipe after it rains. If not, open the valve and allow the water to flush any blockage and then close it to the correct position again.
  • How do I clean and maintain it?
    The unit needs very little maintenance but it is important to check it occasionally to make sure the flush pipe is draining. Over time dirt will build up in the flush pipe and can eventually block the drain. To remove any build up, simply unscrew the drainage plug completely and allow the water pressure to clear any dirt. The insect screen is self- cleaning and should be automatically cleaned when rain enters the device. If it does become blocked for some reason simply unscrew the leaf screen to access the insect screen.
  • Where can I buy it?
    Superhead can be purchased through our web store or from all Reece irrigation stores and other good rainwater stores. Please reference product code SH-01
  • How do I become a reseller and/ or installer?
    Trade and wholesale pricing is available for trade and wholesale customers. Please contact us if you would like more information
  • Can I install it myself (DIY)?
    Yes. The Superhead is easy to install if you have a basic handyman skills. There are a number of ways to that the Superhead can be installed so feel free to configure it how you want. If you need some help then contact us. If you are not confident or just can't be bothered, then any plumber should be able to install it for you.
