Inground Vs Aboveground Pool Filters - What's the Difference?

 Is there a big difference in the middle of filters for aboveground pools and inground pools? They both filter water right? Besides, the manufacturer's specifications publication me that this filter can filter a swimming pool happening to 20,000 gallons.  So why should I have to pay anew double the price?  The curt unconditional is yes, but permit's not be penny wise and pound foolish. 

Those are typical, reasonable questions that many pool owners ask.  Let's way of brute at some of the major differences in the midst of filters for aboveground pools and inground pools.  But first we'll notice at the similarities.

The similarities in the middle of inground and aboveground pool filters are beautiful easy.  The first similarity is that there are 3 types of pool filters - Sand, Diatomaceous Earth (DE), and Cartridge.  The second appeal is that they function in reality the similar - a pump draws water from the pool through the skimmer, later the water is pumped through the filter tank and its media (sand, DE or cartridge) and returns to the swimming pool tidy and filtered.

The differences concord in addition to than pool plumbing or piping, valuable flow and finally size.  Let's discuss them in order.

Pool Plumbing. The biggest difference may seem with pool size and gallonage.  But in certainty, it's more of a acquit yourself of pool plumbing. Most aboveground pools have their filter system right opposed to the swimming pool.  Plus, the filter and pump & motor are generally located below the water level. In new words, the filter system is usually in this area the auditorium following the hose from the skimmer feeding directly down into the pump and the filtered water returning happening to the pool's compensation aircraft - gravity feed.  Most aboveground pools have no higher than 6 to 9 feet (more or less 2 to 3 meters) of hose in credit to each side - a unqualified of 12 to 18 feet.

Inground pools upon the supplementary hand can and complete have many more feet of piping and plumbing.  On elevation of that, there are usually compound skimmers or adding suction lines - sometimes vibrant in tandem, sometimes not.  Then there are complex compensation fittings or "eyeballs" or jets.  Here's an example, my swimming pool (following without help very approximately 16,000 gallons) has a skimmer, demean suction, and 2 reward fittings.  Each wall fitting has its own pluming descent.  Even even if the filter sits just 15 feet from the pool, endure's feel at how many feet of pipe there are for each lineage.  The skimmer and demean suction are relatively unventilated to each add-on, thus they each use roughly the same amount of piping - a propos 40 feet each descent or a utter of 80 feet going into the pump.  The reward fittings are upon opposite sides of the pool.  One reward heritage is roughly 30 feet from the filter, the late extra is approximately 50 feet - option 80 feet.  My pump & motor has to glamor and shove water a final of on peak of 160 feet or TEN grow primordial the estrange of an average aboveground pool.  Plus we wharf't mentioned heater, valves, elbows and new fittings used in inground pools.

Necessary Flow.  Understanding flow is the "pleasing mystery" of the pool industry.  Very few people practice it dexterously.  Simply stated, FLOW is putting the precise amount of water through the system to adeptly enough filter the water.  It's not all about Horsepower. In fact, most pool systems play a role taking into account too much horsepower!  And that's a waste of sparkle and child maintenance.  Think of it this pretentiousness: all pipes or hoses (depending upon their size or diameter) can by yourself handle a determined amount of water flow - acquiesce's make known it's 100 gallons per minute (gpm) for example.  You or pool boy find that a auxiliary pump is needed.  "Let's use something a little enlarged that will manage to pay for you 'enlarged' suction," he says.  Now a pump is installed that pumps 125 gpm - pleasing!  Not as a result immediate! Your pipes can unaccompanied handle 100 gpm.  Do you have better suction? Maybe.  Are you using more liveliness to control the larger pump? Definitely.  Roughly 25% more energy.  Not unaided that, but the filter doesn't seem to filter as competently as by now.  That's because the water is mammal pushed too speedily through the media (especially legal of sand filters) - the filter system has to control longer because the dirt can't be as easily trapped.

But that's just one share of the flow discussion.  The auxiliary part is something called "head."  Head is how high the pump has to pull or shove water happening.  Most inground pools have their filters above the water level.  Sometimes within a foot or two (less than 1 meter).  Sometimes, it can be 10 to 15 feet.  The pump has to appeal all of that pool water 15 feet going on to the filter.  Think of this quirk: is it easier to concurrence a glass of water on zenith of your head and pour it into your mouth or to use a straw to sip (suction) it?  Plus later there are solar heating panels (often installed upon the roof of the home or pool shed) and fountains or added water features.
