"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

Losing some water from splashing and evaporation is normal. However, if you notice a rapid drop in the water level or are adding water more frequently than usual, you might have a leak. Other common signs of a pool leak include:

  • Unexplained soft, mushy, or wet spots in the yard.

  • Cracks in the pool's structure or falling tiles.

  • Higher-than-normal water bills.

  • Persistent algae growth or water discoloration.

  • Standing water near the pump, pipes, or other pool equipment.

Yes, swimming in a pool with high calcium hardness is considered safe as long as you have sufficient chlorine and pH levels to keep bacteria growth under control. The main issue with high calcium hardness is that it damages your pool through rust and corrosion. However, if your water is hard enough to corrode your pool, you might want to consider finding methods to make it safe for drinking at home.

The type of sand you need for your sand filter depends on the manufacturer’s instructions, but you’ll need to use sand specifically for pool filters. Silica sand is a wallet-friendly, common choice that’s relatively easy to replace. You’ll choose between various grades of sand and different-sized sand grains.

At noon, when the sun is at its highest point, sunlight can naturally increase the temperature of a pool by 0.7 degrees each hour, but this can depend on other external factors. For example, evaporation caused by the sun will cause a pool to lose up to 5 degrees for every 1/2 inch of water evaporated. Using a water heater will produce more reliable results.

Concrete pools have the longest life span. As long as you properly maintain your concrete pool, you can expect it to last 50 to 100 years. That said, you will need to resurface your concrete pool as it ages. Fiberglass is durable, but fiberglass pools generally only last around 25 to 30 years. That said, some high-end fiberglass pools can last more than 50 years if they’re well-maintained.
