When replacing a fountain pump or choosing a new a single, very first there are some important terms to hold in thoughts: "Head": This is the maximum vertical lift of the pump. For example, a 6' head implies the pump is rated to pump water up to 6 feet high. Note, however, that at 6 feet the pump would be providing quite tiny water, with gallons per hour about zero. So if you want to pump, say, 200 gph at 72",  you will probably want about a 300-600 gallon per hour pump to do the job.  "GPH" : Gallons per hour, usually rated at various heights  "GPM" : Gallons per minute, normally rated at diverse heights  "Pump Curve" : The quantity of water volume "curved" according  to several heights. A 500 gallon per hour pump, for instance, may pump 500 gallons per hour at " lift, 350 gallons per hour at 24" of lift, and so forth. When getting a pump for the initial time or when looking for a replacement pump, it is important that you know how a lot of 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 factor is the size of the pump, as covered above. But you also should consider how wide your tubing will be. Tubing is measured in two techniques: inside diameter (i.d.) and outside diameter (o.d.). Quite skinny i.d. tubing will drastically minimize water flow. Numerous buyers are shocked when they find that, after hooking up their 500 gallon per hour pump to 1/2" inside diameter tubing, they are only finding what they contemplate a trickle. We had an engineer do some calculations for us to illustrate the issue. Using 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 nonetheless utilizing 1/two" tubing, you will increase volume only slightly, to 264 gallons per hour! The lesson is this: When acquiring a pump, discover out what size of tubing is supposed to go with it. Another problem is running the tubing as well far. Long lengths of tubing produce 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 good notion to use 3/4" tubing as an alternative so as not to cut down also much on flow.  How significantly water do I require? What size of pump? This query is answered in element by regardless of whether you want a "trickle" or a roar. When you purchase a fountain, you will normally locate a recommended flow. For waterfalls, use this as a rule of thumb: for every 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 building a 12" wide waterfall that is 3 feet tall, you need to buy a pump that will be pumping 1200 gallons per hour at three feet of height. For little ponds, anytime achievable, it is a excellent notion to recirculate the water once an hour, a lot more frequently if achievable. As a result, if your pond is 500 gallons, attempt to purchase my life ionizer 9200  a pump that will recirculate water at a rate of 500 gallons per hour. For truly  large ponds, this is not required and is far also pricey.
