"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 FAQs, answered by experts

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.

A pool heater is worth the expense, given that it can extend your swimming season by several months, depending on where you live. For many, adding a pool heater allows the pool to remain in service from May through mid-October. Even temperatures in the 40s and 50s are tolerable when the water in the pool is heated.

A fiberglass pool lasts up to 30 to 50 years with proper maintenance. For the longest possible lifespan, keep your pool water pH as close to seven as possible. Test your water levels regularly, run your pool filter daily, and avoid draining the pool. Once your pool is 20 to 30 years old, you can prolong the lifespan by refinishing the shell.

You cannot DIY a gunite pool—unless, of course, you’re a homeowner who happens to also be a professional pool installer. And even pros need to have experience with gunite pools, in particular, before installing one. Only a skilled gunite pool technician can install this type of pool—it’s not a project you can do yourself.

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.
