Is there a big difference between filter for aboveground pools and underground pools? Both filter water properly? In addition, the manufacturer's specifications are delighted that this filter will filter can say a pool of up to 20,000 gallons. So, why should I pay more than double the price? The short answer is yes, but we were not penny wise and pound foolish.
These are typical questions that many ask reasonable pool owners. Let us look at some of the major differencesbetween filter for aboveground pools and underground pools. But first we will look at the similarities.
The similarities between underground and aboveground swimming pool filters are fairly simple. The first similarity is that there are 3 types of pool filters - sand, diatomaceous earth (DE) and cartridge. The second similarity is that they essentially the same work - a pump draws water from the pool through the skimmer, then the water is pumped through the filter tank andMedia (sand, DE or cartridge) and returns to clean the pool and filter.
The differences lot with pool plumbing or pipes, the necessary power and finally size. Let's talk about them in order.
Pool Plumbing. The biggest difference may seem like pool-size and gallonage. But in reality it is more a function of the sanitary pool. Most aboveground pools have their filter system next to the swimming pool. Plus, the filter and pump and motor are usuallyis located below the water surface. Jump jet, in other words, the filter system is usually on the floor with the hose from the skimmer feeding down into the pump and the filtered water back to the pool - gravity feed. Most aboveground pools not more than 6 to 9 meters (about 2 to 3 meters) of hose on each side - a total of 12 to 18 meters.
Inground swimming pools on the other side can and must have a lot more feet of piping and sanitary systems. At the beginning of thesometimes there are usually several other skimmer or suction lines - working in tandem, sometimes not. Then there are multiple return furniture or "eyeball" or jets. Here is an example, my swimming pool (with only about 16,000 gallons) a skimmer, bottom suction, furniture and 2 back. Each has its own wall mounted plumbing line. Even if the filter is only 15 meters from the pool sits, we'll see how many feet of pipe are available for each route. The skimmer and lower intake --are relatively close together so that they are each about the same amount of pipes used - about 40 meters per line or a total of 80 feet going into the pump. The return of furniture are on opposite sides of the pool. A return over 30 yards from the filter, the other about 50 meters - 80 meters further. My water pump & engine pull and push a total of more than 160 meters, or ten times the distance of an average above-ground pool. Plus we do not mention heating, valves,Elbows and other fittings used in underground pools.
Necessary electricity. Understanding flow is the "big secret" of the pool industry. Very few people practice it is good. Simply put, FLOW is not put the right amount of water through the system adequately filter the water. It's all about horsepower. In fact, most pool systems with too much horsepower! And this is a waste of energy and money. Look at it this way: all tubes or hoses) (depending on their size or diameter can be parallel flow, only a certain amount of water - let's say it's 100 gallons per minute (gpm), for example. Pool Guy, or you decide that a new pump is needed. "Let's use something a little bigger that you will" give better "suction," he says. Now, a pump is installed, pumps 125 gpm great -! Not so fast! Your pipes can only handle 100 gpm. Do you have a better exhaust? Maybe. Do not use more energy to run the larger pump? Absolutely.Around 25% more energy. Not only that, but the filter does not seem to filter as much as before. This is because the water is too fast, driven by the media (especially for sand filter) - filter system running longer, because the dirt can be trapped so easily.
But that is only part of the current discussion. The other part is the so-called "head." Head is to consider how high the water pump or drive. Most inground pools have theirFilter above the water. Sometimes within a foot or two (less than 1 meter). Sometimes it can be 10 to 15 meters. The pump has all of this pool of water 15 meters high drag to the filter. Think of it this way: it's easier to keep a glass of water over his head and pour it into your mouth or use a straw to (suction) it? Plus then there sip of solar collectors (often on the roof of the house or the pool throwing installed), and wells or other water --Features.
Size. Finally, we come to big. Pool size. Filter size. It is all important. Where an aboveground pool filtration system filters 20,000 liters Yes. But is a surface filter system in a position to properly water resistant to 100 meters and the pipelines and create enough traffic in the pool water down to 6 or 8 feet in depth and up again? Or how about doing everything that the push-push-plus always the water 25 to 30 meters in various Directions? Inground pumps are made to do all this, push and pull of water. Aboveground pumps can not.
How about a filter size? Inground pools typically have 20,000 to 40,000 gallons of water. All the water must be filtered with 2 to 3 times daily for the best performance (see our article on Ezine Proper edition "Circulation - First Key to Good Pool Care" for more information ). A larger filter for the larger volume of required> Water.
) As a necessary aside, larger aboveground pools (27 m long and larger, and 18 x 33 oval and larger should check the system using a properly sized underground filter. After the first season, many large above-ground pools experience water quality problems due to inadequate filtering systems. Unfortunately, these pools are "hampered by the problem, only a skimmer and a back-and cut-out. Ask your pool professional to configure your systemright. Does it cost more initially? Yes, but you will get much more in satisfaction.
