"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

Installing an infinity pool takes up to 12 weeks. It can take as long as 20 weeks if you have a complex design, are building a pool in an inaccessible area, or face weather-related construction delays. Either way, this is a big job that requires a lot of time and labor to get it right. Pool construction is not a job that should be rushed, as poor installation can lead to expensive recurring repair costs. 

The average pool loses one-eighth of an inch of water every day. However, how much your pool will lose depends on various factors, such as water temperature, climate, and weather. Warm water will evaporate more quickly than cold water, and pools in low-humidity climates will experience faster evaporation. However, this doesn’t mean you’ll need to constantly refill your pool.

High alkalinity, which is above seven on the pH scale, is the result of improper chemical levels in the pool. Each chemical you use to keep your pool clean has a different pH, so a ratio that isn't optimized for your pool size may cause the number to go above 7.8, the high end for a good pH range in most swimming pools.

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.

You should add chlorine within 48 hours of filling your pool with water. In just 24 hours, bacteria and algae will begin to grow and contaminate your water. After that point, you’ll need to shock the water with high levels of chlorine, and you’ll likely need to do additional vacuuming to get the pool clean. It’s important to check your chlorine levels two to three times a week and add more chlorine as needed to maintain a healthy level.
