The liner can be hidden with boulders, rocks and pebbles, larger ones may need concreting in place. Don’t worry if you have none left over, small sections of liner are available to purchase at very reasonable costs. Lots of pond keepers will have a spare length of pond liner and underlay left over from when they installed their pond, this can be used to create a base for the waterfall.
#PREFORMED POND WATERFALL INSTALL#
You can install the waterfall on a natural slope or hill, or you can create the slope yourself using soil and sand. You can then build up the area around the waterfall with flowers, foliage and rocks or pebbles if desired. It is recommended that you conceal a length of pond liner under the cascade to catch any water splash and return it to the pond. Preformed moulded waterfalls will need to be positioned on a mound of dirt at the edge of the pond. Most pond keepers will want to leave their filter running 24/7 but may want to turn the waterfall off, in this case a separate pump would be perfect. If you will be using a separate pump for your waterfall, simply use the above calculation to work out the flow rate required and select a pump that matches that flow rate.
IMPORTANT: You can only feed the waterfall from a box filter if the filter outlet is higher than the top of the waterfall. These adaptors will fit onto the filter’s outlet with one flow of water going to the waterfall and the other going straight back into the pond.
If the volume of water leaving the filter is too much for the waterfall then some of the water will need diverting using a ‘Y’ adaptor. If you will be feeding the waterfall with water from your filter, as in most garden ponds, then the volume of water may be determined by the filters flow-rate. Use our Waterfall Calculator to help work out the flow rate you require! Using this rule, a waterfall measuring 35cm wide and 1m high will require a flow rate of 4500LPH. Follow this basic calculation to work out the flow rate required for your waterfall:Įach 100cm of height will require 1000LPH. Will the waterfall be supplied with water from the filter? If so, make sure the filter outlet can reach the top of the waterfall!īefore starting any waterfall, consider the size of the pump required as the higher and wider the waterfall, the larger the pump needed. Your waterfall will need maintenance so ensure you allow room for easy access. Think about if you want the waterfall to be visible from your patio or decking, perhaps consider a location near the bedroom if you like the sound of running water at night. The first thing to consider is the location of your new waterfall! Sit in your favourite spot and visualise where a waterfall would fit into the landscape of your garden. These waterfalls generally require a powerful pump to maintain the curtain effect of the water. They produce a sheet/curtain of water and often come with built in lights. More work than a preformed mould however you have control over every aspect of the design.īlade waterfalls offer a more modern take on the popular garden feature and are usually installed onto a wall or brickwork around the pond. Using a section of pond liner and rocks/pebbles, you can match the waterfall to the style of your garden very easily. Self-made waterfalls allow you to create a bespoke design, perfectly suited to your needs. They can be installed quickly and are the most popular way of adding a waterfall to a pond. There are many types available including plastic, resin and fibreglass and they all come in a range of colours and sizes. Preformed waterfalls are the easiest way of installing a feature to your existing pond. To maximise the enjoyment of the waterfall it is important to plan the build properly, just follow our guide to ensure everything is covered! They are an ideal way to return the clean, filtered water back to the pond and will add oxygen into the water. A useful guide covering many aspects of waterfalls.Ī waterfall is a very simple and effective water feature that adds a relaxing noise and focal point along with ever helpful water movement.
