When replacing a fountain pump or deciding on a new a single, very first there are some key terms to maintain in mind: "Head": This is the maximum vertical lift of the pump. For example, a 6' head indicates the pump is rated to pump water up to 6 feet high. Note, however, that at 6 feet the pump would be providing really tiny water, with gallons per hour about zero. So if you need to pump, say, 200 gph at 72", you will most likely need to have about a 300-600 gallon per hour pump to do the job. "GPH" : Gallons per hour, typically rated at distinct heights "GPM" : Gallons per minute, generally rated at distinct heights "Pump Curve" : The amount of water volume "curved" according to different heights. A 500 gallon per hour pump, for instance, may possibly pump 500 gallons per hour at " lift, 350 gallons per hour at 24" of lift, and so forth. When purchasing a pump for the initial time or when searching for a replacement pump, it is essential that you know how many 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 few factors. 1 element is the size of the pump, as covered above. But you also should think about how wide your tubing will be. Tubing is measured in two ways: inside diameter (i.d.) and outside diameter (o.d.). Very skinny i.d. tubing will significantly decrease water flow. Numerous buyers are shocked when they uncover that, following hooking up their 500 gallon per hour pump to 1/two" inside diameter tubing, they are only finding what they think about 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 rising the pump to 450 gallons per hour, but still using 1/two" tubing, you will increase volume only slightly, to 264 gallons per hour! The lesson is this: When acquiring a pump, locate out what size of tubing is supposed to go with it. One more problem is running the tubing too far. Lengthy lengths of tubing create resistance. If your pump calls for 1/2" i.d. tubing, for instance, but you are operating the tubing twenty feet from the pump, it is a very good thought to use 3/4" tubing instead so as not to cut down also significantly on flow. How significantly water do I need? What size of pump? This question is answered in part by whether or not you want a "trickle" or a roar. When you acquire a fountain, you will typically uncover a advised flow. For waterfalls, use this as a rule of thumb: for every single inch of stream width or waterfall "sheet," you will want to deliver 100 gallons per hour at the height you're pumping. So if you are creating a 12" wide waterfall that is three feet tall, you need to acquire a pump that will be pumping 1200 gallons per hour at three feet of height. For small ponds, whenever attainable, it is a excellent idea to recirculate the water once an hour, more often if possible. Therefore, if your pond is 500 gallons, try to purchase a pump that will recirculate water at a rate of 500 gallons per hour. For genuinely large ponds, this is not necessary and is far also expensive. alkaline water
