POOLS

During summer, a pool exposed to sun and wind can lose up to 8 litres (8mm) of water per square metre per day!

Downpipe rainwater diverters are recommended for topping up pools but harvested water needs to be of good quality and contaminant free. Ideally, water diverted to a tank or pool should pass by an effective first flush AND debris divert system.

  • SUPADIVERTA is available with an optional first flush kit that captures the initial roof wash.

  • SUPADIVERTA has a 750 micron (.75mm) filter that diverts solid bird droppings and other debris throughout the entire rain event.
  • The middle (FLUSH) outlet continuously captures much of the smaller debris that passes through the filter to the reservoir floor.


Don’t let poor product choice result in grit, decaying organic matter and phosphate enriched bird droppings upsetting your pool’s chemical balance.


HINTS

  • If an outside T.V. antenna (bird roost) is close to a downpipe, consider harvesting another downpipe if the water is to be diverted to a tank or pool.

  • Large pools will need more than one downpipe harvested.

  • Diversion is beneficial during light rainfall but if heavy rainfall is expected, do you need to divert additional water? Pools overfilling during heavy rain require additional and costly chemical treatments to restore the pool’s chemical balance.

  • Silicone based chemical pool covers are safe and claim evaporation savings of 40-50%. AQUATAIN is probably the best known of these products.

  • SUPADIVERTA’S syphonic drainage system allows high flow rates over long distances. This allows SUPADIVERTA to be fitted to high yield downpipes away from the pool.

  • Ideally, pool owners should top up the pool with decanted water from a rainwater tank during dry periods. The cost of tanks has fallen and many sizes and shapes are now available.


CONNECTIONS
SUPADIVERTA is easily plumbed and can be connected to a hose when required. Aquatrek recommends using either an 18mm garden hose or 19/25mm poly pipe. A 12mm garden hose has little internal volume and high friction loss.

Plumbing the supadiverta

To connect the 2nd and 3rd priority outlets to a single horizontal pipe, use an elbow and Tee as shown above. The photo shows the use of a PVC 20 x 25 mm reducing elbow and a PVC 20 x 25 mm reducing Tee. A short PVC pipe cut to size is needed to connect the elbow to the Tee. When connecting to a detachable 18 mm hose, 20 mm PVC pipe and fittings are used.

There are several ways that a temporary hose can be fitted but an inline tap must be fitted along the horizontal pipe plus a connection that the hose can attach to.

PVC PIPE
Fit a 20 mm inline tap into the horizontal pipe. The PVC tap/valve shown is a push-fit connection. Fit a 20 mm PVC adaptor over the pipe and then screw a 20 mm poly sprinkler adaptor into the PVC adaptor. The PVC adaptor has a female thread at one end.  When fitting the hose, open the tap to flush out the pipe and then snap fit the hose to the sprinkler adaptor.


POLY PIPE
Join the 19 mm vertical drops to a 19 mm horizontal poly pipe by using a 19 mm poly Tee and a 19 mm poly elbow.  

Fit a length of horizontal 19 mm poly pipe to the Tee and fit a poly inline tap along its length. Attach a hose connector to the end of the poly pipe. A coupling is then used to join a hose to the other connector.

There are also other fittings available that come in different sizes.
