The Arc Stainless Steel Curved Waterfall is a premium water feature designed to add elegance, style, and tranquillity to ponds, pools, and garden landscapes. With its graceful curved design and polished stainless steel finish, this waterfall creates a smooth, eye-catching flow of water, transforming any space into a calming retreat.

Standing at 170mm in height and available in widths ranging from 200mm up to 800mm, the Arc Waterfall offers flexibility to suit both small decorative ponds and large, striking water displays. Whether used as a subtle feature in a private garden or as a bold focal point in a pool or landscaped project, it delivers a visually stunning and relaxing water effect.

The Arc Waterfall is manufactured from high-grade polished stainless steel, ensuring strength, durability, and resistance to corrosion. The mirror-like finish adds a modern touch while being easy to maintain, making this waterfall both a stylish and practical choice.

Designed with installation in mind, the base features laser-cut holes at either end for secure mounting, while the choice of inlet positions – back or bottom – allows for flexible fitting into your pond or pool system. Both inlets are 1″ BSP, making it compatible with standard fittings.

The curved spout not only enhances water flow but also complements contemporary and traditional landscapes alike. With the option to select your preferred waterfall width and inlet position, the Arc Waterfall can be customised to perfectly suit your setup.

Pump and flow rate guidance

Water blade pump sizing is one of the most common areas where people get caught out. The important figure is not simply the maximum flow printed on the pump box, but the actual flow reaching the water blade after vertical lift, hose size, bends and fittings have all taken effect. As a guide, allow around 1,250 litres per hour for every 100mm of blade width for a strong, even sheet of water. Wider blades and longer spout projections need more water to keep the sheet full and consistent.

Blade width	Suggested starting flow at the blade
200mm	Approx. 2,500 LPH
300mm	Approx. 3,750 LPH
400mm	Approx. 5,000 LPH
500mm	Approx. 6,250 LPH
600mm	Approx. 7,500 LPH
800mm	Approx. 10,000 LPH

Because head height can reduce the delivered flow significantly, we strongly recommend choosing a controllable pump where possible. A variable flow pond pump lets you oversize slightly to overcome losses, then turn the flow down until the blade looks right. Good options include the Evolution Aqua Varipump 10000, PondXpert VariFlow SINE 10000 and AquaForte DM Vario S 10000, depending on the width of the blade and the height of the installation.

Hose, clips and installation extras

Most pump-fed water blades work best with a short, neat run of correctly sized flexible pond hose. For simple installations, standard flexible pond hose is usually suitable. For higher flow rates, longer runs or where you want to reduce friction losses, the heavy duty flexible pond hose is the better option because the smoother bore helps maintain more of the pump’s output.

Always secure hose tails with suitable stainless steel clips. These products are supplied with hosetail fittings depending on the model, but the hose and clips should be chosen to match your pump and pipework layout. We recommend using stainless steel hose clips on flexible hose connections, especially where the blade is built into a wall and access may be awkward later. A pair of 20-50mm stainless steel hose clips has also been added as an optional extra on the pump-fed water blade pages for convenience.
