When replacing a fountain pump or choosing a new life ionizer 9100 1, initial there are some crucial terms to hold in mind:

"Head": This is the maximum vertical lift of the pump. For instance, 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 delivering extremely small water, with gallons per hour around zero. So if you want to pump, say, 200 gph at 72", you will almost certainly 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, usually rated at diverse heights

"Pump Curve" : The amount of water volume "curved" according to several heights. A 500 gallon per hour pump, for instance, may well 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 seeking a replacement pump, it is essential 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 few variables. A single aspect is the size of the pump, as covered above. miracle max But you also ought to take into account how wide your tubing will be. Tubing is measured in two approaches: inside diameter (i.d.) and outside diameter (o.d.). Really skinny i.d. tubing will drastically reduce water flow. Many customers are shocked when they uncover that, right after hooking up their 500 gallon per hour pump to 1/2" inside diameter tubing, they are only acquiring what they think about a trickle.

We had an engineer do some calculations for us to illustrate the issue. 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 still employing 1/two" tubing, you will enhance volume only slightly, to 264 gallons per hour! The lesson is this: When buying a pump, discover out what size of tubing is supposed to go with it. An additional difficulty is running the tubing also far. Long lengths of tubing produce resistance. If your pump calls for 1/2" i.d. tubing, for instance, but you are running the tubing twenty feet from the pump, it is

a excellent concept to use 3/4" tubing instead so as not to reduce down too much on flow.

How much water do I need? What size of pump? This question is answered in part by no matter whether the link you want a "trickle" or a roar. When you purchase a fountain, you will normally discover a recommended flow. For waterfalls, use this as a rule of thumb: for every single inch of stream width or waterfall "sheet," you will require to deliver 100 gallons per hour at the height you're pumping. So if you are building a 12" wide waterfall that is three feet tall, you want to acquire a pump that will be pumping 1200 gallons per hour at three feet of height. For modest ponds, whenever possible, it is a good concept to recirculate the water as soon as

an hour, far more frequently if feasible. 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 really

big ponds, this is not necessary and is far as well high-priced.
