Spa Pond Water

Building your own waterfall can be a rewarding experience, however, related to water can be complicated so you should arm yourself with as much information as possible to build something you will be happy with.

Minimum flows

For every inch width of the chute should have a minimum 100 to 150 GPH (gallons per minute) of water supplied by the pump. cascaded Example: if you want the top plate of the cascade of having an area of 10 inches wide, where the water turns and for its waterfall, you would need a pump that can provide 1000GPH. Furthermore, it is necessary to understand how the pumps are rated to ensure that you get the desired effect you are looking for. There is a loss of efficiency in the movement of water through pipelines and must account for this to ensure that receives its waterfall water flow you need.

Scores of the pump and the pressure drop

The maximum score for your pump, for example 1000GPH refers to a pump with a zero pressure head. Pressure head refers to the weight of the water pump is to lift and push. If the pump has to lift the water a long way that will produce less LPH. Simplified, the pump will have a rating that refers to the amount of vertical rise of water will do. Provide a chart in the specifications of the pump that provides the LPH zero pressure in the head, but the wait GPH with a foot of vertical rise, or two feet of vertical elevation, or five feet of vertical rise, and so on.

Accessories cause the pressure drop also

Other factor in this equation is accessories such as ninety degree elbows, forty-five degree elbows and bends in the pipes or valves also increase the pressure head. A bomb that has to raise the water about a foot, but also through a series of four or five fittings elbow 90 degrees have significantly less gph pushing a bomb through a straight run of pipe.

The height and width of the waterfall that identify the requirements of the pump

It is therefore necessary to determine how high the pump needed to get the water to reach its top bowl and also how you want the big dump in your bowl up to be. This gives you an idea of what size pump you need. Assuming the same 10 inches wide and a drop of landfill five meters to reach the top plate, would have to find a pump that can produce a minimum of 1000GPH with a head of 5 feet. This means that the label on the pump is probably around 1250 GPH to the zero reference pressure for the pump with a yield of about five feet 1000GPH head.

Calculation of pressure head pipe fittings

It is recommended to note that you will have fittings, bends and restrictions in pipes have to get from lake to its upper bowl so this will also increase the pressure in the head. In larger applications the number of bends in the pipe, length and fittings used are calculated to determine the exact pressure loss for water to reach your destination. For smaller applications such as its cascade of this calculation is unnecessary. When building your plumbing of your pool at the top of the waterfall to try to use as few fittings and bends in the pipe as reasonably possible. Above all try to prevent the fittings back to back like two or three bends ninety degrees in a short section of pipe. Accessories and curves in succession short because the more head pressure than the same number of accessories and more spread. For simplicity not calculate the number of accessories you will use to build its waterfalls, but instead large pump for a minimum of ten percent.

Now the equation all together Plumbing

If you have a cascade of 10 inches and a lift of five feet, and you represent 10% of the additional flow that is lost in the fittings and pipes run ending the next.

1000GPH at a pressure head of five feet of a pump will be announced with greater 1250gph flow as referring back to zero pressure head. To account for their accessories need 10% more flow, another 125 gph or more than for 1250 GPH pump. This means that the minimum qualification of the pump 1375 GPH would be considered. Round this number up to 1400 or even 1500 GPH rating as bombs are usually sold in increments of flow and it is likely Not find a 1375 GPH pump.

The reason it is necessary to consider this at this stage is that you need to determine the size of the pipe to run a waterfall in the pond in the upper container. If you have calculated that the flow rate needed to achieve the scope of the waterfall is thinking you can find the pump that is needed to get this from your local hardware store or supply pump. The most suitable type of pump for most DIY cascades is a submersible pump. You'll have to sit directly in the pond and as a result of the black pump is better than a light color that will be very visible. You may use remote pump as a pool can use, but this will increase the difficulty of installing the plumbing system considerably as well as increased project cost as well.

Once you locate the pump to be used for cascade can now start installing the plumbing system, and consider details such as the creation of a chase electrical cable to allow the pump to be installed out of sight instead of hanging out the side of the pond.
