Blade water features, also known as water blades, are some of the most modern water features available. Instead of large, bulky structures like fountains or waterfalls, a blade water feature has a minimalist design. It consists of a flat, bladelike spout, which produces a wide, uniform sheet of flowing water using liquid-regulating devices known as baffles. Apart from their spouts, blade water features consist of piping or tubing, water pumps and reservoirs.
You can mount a blade water feature on to a variety of surfaces, provided they are horizontal. These include interior drywall or plaster walls, exterior brick or stucco walls or even the side of a wooden pool deck. By having a blade water feature empty into--and draw its water from--an existing water source, such as a pool or pond, you can eliminate the need for a reservoir.
Blade water features are available in two primary installation varieties: rear-entry and bottom-entry. With a rear-entry blade water feature, the plumbing outlet is at the rear of the spout, which means the water feature's piping or tubing will be hidden entirely behind the installation surface. In comparison, a bottom-entry blade water feature has its plumbing outlet at the bottom of the spout. While a bottom-entry water feature, with its exposed plumbing, may be at an aesthetic disadvantage, the installation process for bottom-entry blade water features is easier because it does not require sawing-out or otherwise clearing a space in the underlying surface.
Manufacturers produce blade water features with a variety of different spout lengths. The longer the length of the spout, the wider the resulting sheet of falling water will be. Common examples of blade water feature spout lengths include 30cm or 11.8 inches, 60cm or 23.6 inches, 90cm or 35.4 inches, 120cm or 47.2 inches and 150cm or 59 inches.
You can install a blade water feature's spout at a variety of heights. However, the higher you position the spout, the more powerful your pump's motor will generally need to be. If your pump is not powerful enough, it will not be able to pump water up the piping or tubing and out the spout. Position the spout of a blade water feature approximately 1 meter or 3.3 feet above the reservoir below. This will help minimise residual splashing and will help prevent the falling water from tapering and losing its uniformity.
Two of the most common materials that manufacturers use to create the spouts of blade water features are plastic and stainless steel. While plastic is the less expensive option, stainless steel is more durable and tends to provide greater aesthetic value.
Blade water features are also available with LED, or light emitting diode, lights. These lights, which connect to the spout, help make the falling water more colourful and brilliant.
