An above ground pool can make an enjoyable addition to your backyard. Far less expensive than an in-ground pool, an above ground pool is also easier to install and just as easy to maintain. They come in a range of sizes to accommodate even small backyards, up to pools that hold tens of thousands of gallons. With proper maintenance and care, an above ground pool can provide backyard fun for many years.
Parts
Above ground swimming pools usually consist of a metal frame that forms the shape of a pool and holds a liner in place. The frame starts with a steel base that fits together and lies on the ground as a foundation. A long sheet of galvanized and painted steel forms the side wall. Reinforced metal columns that run from the base of the pool to the top edge at regular intervals around the pool support the side walls. A top rail attaches in sections to the columns to complete the pool frame. The vinyl liner fits inside the frame to form a waterproof barrier.
Filtration
Above ground pools require filtration to remove particulate matter, biological contaminants and other items that interfere with keeping the pool clean. An electric pump draws water from the pool and through a filter basket to catch leaves, insects and other large items. The pump drives the water through a filter tank. A sand filter is among the most common types for above ground pools. The pool water percolates through the sand, which catches any remaining debris. The clean water then returns to the pool.
Installation
Choose an area for the pool that is level with a solid soil base. Frequently, installation requires laying down a layer of sand or rock dust to provide a smooth surface beneath the pool bottom. Assemble and align the base on the site. Unroll and stand the metal sheet around the base. Attach the columns. Place the liner in the center of the pool and unfold it, carefully. Attach the edge of the liner to the top of the frame and fasten it with special clips. Install the top rail sections and attach any filtration. You can now fill the pool with water.
Maintenance
Regular maintenance helps to keep your pool clean and ready for swimming. Test your pool water frequently to ensure it is at the proper pH and has sufficient chlorine in it. Add chlorine on a regular basis to reduce bacteria or algae growing in the pool. Add other pool chemicals, as needed, to adjust the pH. Filtration systems should be back-washed regularly to remove any particulate matter from the filter. If your filtration system uses a replaceable filter, change the filter on a regular basis.
Liner Repair
Occasionally, damage can occur to an above ground pool liner. Holes in the liner can drain a pool surprisingly quickly. Patch kits are available, made of sheets of vinyl that you can cut to size and attach with adhesives that will work even underwater. Most patch kits can handle holes from the size of a pinhole to a softball sized hole. Snorkeling equipment comes in handy when making repairs to a liner.
