This unit projects water out from wall in a clear and even arc, re-entering water approximately 200mm away from wall providing a dramatic, lively effect. This involves senses and proves difficult for even most staid personality to resist urge to reach out and play with curtain of water produced by this unit. Further enrichment is accomplished with use of lighting at night. A simple submersible spotlight positioned under curtain of water is all that is required.

Installation

This unit should not be installed any higher than 1.2m above surface of water in catchment reservoir. The water will begin to break up if installed any higher. A high-flow projecting waterfall is available which may be installed up to 2.0m high (please enquire).

Flow Requirement

This unit requires approximately 7200 litres per hour per metre width. This should produce a film of water approximately 5mm thick. Some adjustment in flow is achievable with use of an inline value. See examples 1 & 2 for further explanation.

Catchment Reservoir

Rectangular Statue ponds are recommended for use with a Projecting Water Wall as catchment reservoir needs to protrude at least 500mm from wall to avoid losing too much water from splash.

Pump

The pump required is governed by flow requirement and head height (ie. ie. height at which waterfall is installed above surface of water in catchment reservoir).

Example 1:- Installing a 1.0m Projecting Water Wall at a head height of 1.0m

This unit has a flow requirement of 7200 litres per hour (7200 (litres) x 1 (metre)) therefore requires a pump that will supply 7200 lph at 1.0m high. Check pump performance charts to find a pump that will supply this flow at required height. In this example a Seerose UP150 will push 7740 lph at 1.0m high and is therefore suitable. Example 2:- Installing a 0.8m Projecting Water Wall at a head height of 0.5m

This unit has a flow requirement of 5760 litres per hour (7200 (litres) x 0.8 (metres)) therefore requires a pump that will supply 5760 litres at 0.5m high. Check pump performance charts to find a pump that will supply this flow at required height. In this example a Seerose UP120 Fountain Pump will push 6840 lph at 0.5m high and is therefore suitable. TIP It is always better to ‘oversize’ pump rather than to purchase a pump that will only just suit. Allowances need to be made for loss of flow through tubing and fittings. It is far more practical to buy a pump larger than required and restrict output buy a valve, as it is impossible to get more performance than maximum specified on any particular pump.

Example 3:

An Aquashift 15000 Pump (210 watt)

210 (watt) x 8760 (hours per year) / 1000 x $0.1447 = $266.19 per year

Example 4:

A 0.75 HP Pool Pump (550 watt)

550 (watt) x 8760 (hours per year) / 1000 x $0.1447 = $697.16 per year

Total cost savings = $430.97 per year ($107.74 per quarter!)

Above we have only considered operational costs; however there are a number of other considerations when comparing a pond pump to a pool pump:

Guarantee/Warranty

All Pond Pumps supplied by Water Features Online are quality pumps and are backed up by Continuously Rated Guarantees of varying lengths (2-5 years). Continuously Rated means that pump is guaranteed to run 24 HOURS A DAY for period of guarantee. Conversely, while Pool Pumps may be of good quality, guarantees are NOT continuously rated and they are usually guaranteed to run for approximately 6 hours a day (read fine print!) for period of guarantee. If a pool pump is run for 24 hours a day then this effectively reduces a 2 year guarantee to a 6 month guarantee.

Noise

This is a factor often overlooked. Pond Pumps are generally submersible and therefore silent. Pool Pumps are generally dry mounted somewhere near water feature and can be very noisy. This is counterproductive when introducing sound of water into a garden.

Maintenance

Both Pool and Pond Pumps require some basic maintenance, they need to be kept clean and free of debris. However, Pond Pumps have fewer moving parts than Pool Pumps, therefore likelihood of breakdowns are greater in a Pool Pump. Often seals on Pool Pumps degrade and need replacing regularly whereas a Pond Pump generally does not have a seal.
