"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

Install Above Ground Pools FAQs, answered by experts

You can find a leak in an in-ground pool by doing a visual check, the bucket test, and a dye test. Keep in mind that skimmers are usually the culprit for in-ground pool leaks. However, if you cannot detect the leak location after running the tests, it’s a good idea to call in a professional pool repair service.

To find a leak in a small pool, place a few drops of food coloring in a random area. If the food coloring flows out, you've found your leak. However, this can be time-consuming and impractical in larger pools. The best option is to hire a pool repair specialist with ultrasonic equipment.

You should always run your pool pump in freezing weather to keep the water moving. Doing so prevents the pool water from freezing and protects your pool from the damage that often comes along with frozen water. You should also run your pool pump when temperatures are approaching freezing, as a precaution. There’s no need to run a pool heater during the winter, as keeping water moving is generally enough to keep it from freezing.

It’s a good idea to wait at least 24 hours after opening your pool before you swim in it. Pool opening often involves shocking the water, and the chemical levels need to come down a bit before it’s safe to swim. You can continue testing your water pH and chlorine levels if you’re in a rush. It’s wise to wait until your chlorine levels drop to under four parts per million (ppm) and you have a water pH of between 7.2 and 7.8. You can artificially lower your water pH to speed up the process.

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.
