When replacing a fountain pump or selecting a new one, very first there are some important terms to maintain in thoughts:

"Head": This is the maximum vertical lift of the pump. For example, a 6' head signifies the pump is rated to pump water up to 6 feet high. Note, nonetheless, that at 6 feet the pump would be supplying quite small water, with gallons per hour around zero. So if you need to pump, say, 200 gph at 72", you will possibly require about a 300-600 gallon per hour pump to do the job.

"GPH" : Gallons per hour, usually rated at different heights

"GPM" : Gallons per minute, typically rated at distinct heights

"Pump Curve" : The amount of water volume "curved" according to numerous heights. A 500 gallon per hour pump, for instance, might pump 500 gallons per hour at " lift, analysis water ionizers 350 gallons per hour at 24" of lift, and so forth. When purchasing a pump for the first time or when searching for a replacement pump, it is essential that you know how numerous gallons per hour you want to pump and at what height (head).

Water Volume The total volume that you will be pumping is controlled by a handful of variables. One particular element is the size of the pump, as covered above. But you also need to consider how wide your tubing will be. Tubing is measured in two ways: inside diameter (i.d.) and outside diameter (o.d.). Quite skinny i.d. tubing will tremendously lessen water flow. Many customers are shocked when they locate that, after hooking up their 500 gallon per hour pump to 1/two" inside diameter tubing, they are only finding what they take into account a trickle.

We had an engineer do some calculations for us to illustrate the problem. Making use of a 300 gph pump with 1/2" tubing is going to restrict your flow to 253 gallons per hour. By growing the pump to 450 gallons per hour, but nevertheless employing 1/2" tubing, you will increase volume only slightly, to 264 gallons per hour! The lesson is this: When buying a pump, locate out what size of tubing is supposed to go with it. Another problem is operating the tubing too far. Long lengths of tubing create resistance. If your pump calls for 1/two" i.d. tubing, for instance, but you are running the tubing twenty feet from the pump, it is

a excellent concept to use 3/four" tubing rather so as not to cut down also significantly on flow.

How much water do I need? What size of pump? This question is answered in element by regardless of whether you want a "trickle" or a roar. When you purchase a fountain, you will usually find a advised flow. For waterfalls, use this as a rule of thumb: for each and every inch of stream width or waterfall "sheet," you will need to deliver 100 gallons per hour at the height you are pumping. So if you are building a 12" wide waterfall that is three feet tall, you want to buy a pump that will be pumping 1200 gallons per hour at 3 feet of height. For modest ponds, whenever feasible, it is a very good idea to recirculate the water when

an hour, a lot more often if feasible. water ionizer Thus, if your pond is 500 gallons, attempt to buy

a pump that will recirculate water at a rate of 500 gallons per hour. For truly

huge ponds, this is not required and is far also pricey.
