"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

The amount of time your fiberglass pool project will take depends on the size of the pool and whether you are installing add-ons like decking and landscaping. Overall, you should expect it to take four to six weeks to install. If you are dreaming of summer pool parties, make sure to budget enough time into the installation schedule to have your pool up and running in time for the swimming season.

If your pool takes longer than one or two days to fill, you might be dealing with low water pressure. Using a water pressure gauge on your outdoor tap, you can check your water pressure. A reading of 40 psi or below is considered low. A leak, a nearby water shutoff, or several other reasons could cause this. 

If the water pressure isn’t a problem, you could have a low flow rate from clogs, corroded pipes, or other plumbing issues. It’s best to call in a local plumber to get to the root of the issue.

Infinity pools do require slightly more maintenance than other pools because you’ll need to constantly monitor the water level. If the water level is out of whack, it won’t correctly flow over the edge, which gives the pool its infinity look. 

That said, the rest of the maintenance is largely dependent on the type of material you choose. Concrete needs a little extra care to prevent algae growth, and you will eventually need to resurface it. Fiberglass and vinyl liners are algae-resistant but they’re not as durable.

Figuring out how to clear a green pool can seem tricky at first, but it’s all about knowing which pool cleaning chemicals to use. You may think of using baking soda to help you with your algae problem, but unfortunately, it won’t help. This is because baking soda only raises your pH and alkalinity levels. 

Instead, you need to use pool shock to clear up a green pool—the shock raises the free chlorine levels and will kill the algae.

Your aboveground pool might technically be able to stand without water, but you shouldn't consider it stable. Aboveground pools need the weight of water to provide adequate stability and prevent the walls from collapsing in. Be sure to fill your pool with water as soon as possible after installation.
