AquaFlo Acrylic Spillways

Projecting or Cascading Waterwall

The Aquaflo range of acrylic spillways are designed to be built in or behind a wall and can be installed in either a swimming pool with chlorinated/salt water or in a pond with fresh water. They can be set up to cascade (trickle gently down the wall) or to project (shoot out in a blade of water) from your feature, depending on the flow of the pump you have connected to it. Available as just the spillway box or with in build LED lights in different colours.

To order, consult the chart and the information below then select the spillway which suits your needs from the drop down list on the side of the page and add to cart. Don't forget to also select your pipe inlet as bottom or rear entry (see diagram below for example of each - bottom entry as shown on the left image and back entry on the right image).

  • Can be used as Cascading Sheet (trickling gently down the wall) or Projecting Sheet (shooting out in a blade of water) water feature
  • ​Can be used in chlorinated or freshwater (pools or ponds)
  • Available with a 50mm or 125mm lip
  • Available with solid White or Blue LED Lights or alternatively with Red/Green/Blue colour changing LED Lights (RGB includes a remote control and several options for patterns)
  • LED light bars can be removed or replaced for easy maintanence
  • Plumbing kits including pipe and fittings you need to connect to your pond pump specific for these spillways available - click here
  • Refer to the bottom of the page for assisting with pump selection
  • Recommended maximum height of 900mm above the water lever for any projecting spillway including Aquaflo. Any higher than this and the sheet breaks up and your feature will be very noisy, potentially beyond the point of being relaxing anymore
  • Matching ponds and troughs available - click here
  • For pump setup information - click here
  • Box dimensions 80mm x 60mm + lip projection
  • Each spillway comes with 32mm BSP female threaded socket inlets. 1 Inlet 300-900mm, 2 inlets for 1200mm

Aussie's Observations about AquaFlo Acrylic Spillways

Rating:
Budget • Good • Better • Best • Superior

Suitable for:

Suitable for almost any situation requring a spillway or waterwall. 125mm lip is perfect for walls the width of 1 brick.

What we liked:

Aquaflo spillways are our most flexible spillway. They are suitable for pools or ponds, can be used as projecting or cascading sheet and are available with or without lights. You can install an Aquaflo spillways in almost any situation.

Less than ideal:

When connected to a pool pump a non-return (one way) valve is required to be fitted to the pipe coming from the pump in order to keep water in the pipe at all times. The inital rush of water from a powerful pool pump runs the risk of cracking your spillway box if the line is not full of water.

Lip Length

50mm & 125mm. Lip extension is measured from the top vertical edge of box to the tip of the lip (point where the water exits) - see the above diagram

What is a Projecting sheet spillway?

A box with a delivery spout is mounted in a wall, a large volume of water passing through this special unit producing a solid sheet of water that projects away from the wall. The sheet of water does not touch the wall, but goes directly into the pond/pool/spa. These units have been designed with an multi chamber internal baffle system for a spectacular flow over the spillway.

What is a Cascading descent spillway?

A box with a delivery spout is mounted in a wall, water flows softly from the spillway and runs down the wall face into the pond or pool. Sheet descent units have been designed with a multi chamber internal baffle system to promote even flow over the spillway.

 

Hint 1: If being used as a projecting sheet effect, never mount higher that 900 mm above the water. The further the water drops, the narrower it becomes due to surface tension. The drop in the photo's above is .9m to give you an idea. Another way to understand this tapering effect is that for every 50 cm of drop, the width of the sheet of water narrows by about 100 mm. After about 90 cm of drop the sheet starts to break up.

Hint 2: Any elbows or tees in the system will reduce flow. On the 2 inlet model spillways, it may be desirable to use two pumps, this will avoid the need for a tee.

Hint 3: Glass .. When water is run down glass, to improve water flow and maintain it's full width you should angle the wall between 2 to 5 degrees

Hint 4: Acrylic .. When water is run down Acrylic, to improve water flow and maintain it's full width you should angle the wall between 5 to 7 degrees

Hint 5: How to neatly get the electrical cable from the pump and the water tube out of the pond cleanly and allow for service. Click here

Choosing your pump


PUMPS: How to choose : A projecting sheet spillway requires a flow of at least 700 Litres per hour for every 100 mm of spillway width. While a sheet descent sheet spillway requires a flow of at least 350 Litres per hour for every 100 mm of spillway width. This flow rate is measured at the spillway, therefore in choosing the pump, the distance* between the surface of the water and the spillway is a factor that only you will know.  We have therefore made a number of suggestions below based on about 1.0m mounting, covering a variety of price points. The (list starts with the best quality and works right).  *The higher the water is being pumped, the larger the pump must be, also on 2 and 3 inlet spillways the flow must be higher because of the tee that is required in the plumbing.
