"One oven doesn't work at all ( my choice, see above), the "working" oven was never calibrated properly so using it is hit or miss. It's time to call American Home Shield to see about replacing the entire unit. I'm waiting to finish other home projects before calling them. I don't know if I'll request Greenway again."

Install Above Ground Pools questions, answered by experts

The formula you’ll use to measure your pool will differ based on the shape of your pool. For a rectangular pool, you’ll use the following formula to find the size in gallons: length x width x depth x 7.5. If the depth changes from one end of your pool to the other, take the average by finding the depth at the deepest and most shallow points and dividing that number by two. Circular and oval pools require different, more complicated formulas, which can be found in this article.

No, shock and chlorine are not the same thing, though they are related and both are used for pool maintenance. Regular chlorine, often in the form of tablets, is a sanitizer used for routine, day-to-day maintenance to keep a steady chlorine level. Pool shock, however, is a highly concentrated dose of chlorine used periodically for a more intense cleaning. It rapidly raises chlorine levels to fix issues like cloudy water or algae growth and also eliminates chloramines, which are byproducts of regular chlorination. Because their purposes and concentrations differ, they are not interchangeable, and proper pool care typically requires using both.

Sometimes, homeowners choose to install their pool on concrete, foam tiles, or patio pavers. Leveled dirt is also fine, as long as it’s not sod or grass. Regardless, you’ll need to install sand as a buffer to prevent your liner from tearing. Some pool installers also use a protective foam pool pad.

It can take anywhere from 12 to 24 hours to fill the average pool with water—and that’s if you use a couple of garden hoses. A water delivery service can fill your pool in one to three hours. Some services even pre-treat the water so it’s swim-ready as soon as it’s filled.

Pool leaks most commonly occur at joints or where different materials meet. The most frequent leak spots include:

  • The Pool Skimmer: Where the plastic skimmer meets the pool's liner or shell.

  • The Pool Liner: Tears can develop in vinyl liners, especially those between 5 and 20 years old. Leaks also occur around the liner's edge.

  • Fittings and Accessories: Areas around return lines, the main drain, and pool lights are common culprits.

  • Pool Equipment: The pump, filter, and filter housing can also leak.

While leaks in underground pipes are less common, they can be costly to fix. It's usually best to check the more common spots before investigating the plumbing system.
