"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 questions, answered by experts

Calcium lumps in a pool are calcium deposits that form when a pool's water parameters are not in the normal range. They can float around on the surface of the pool water, making it look and feel dirty. The most common causes of calcium lumps in pools are calcium hardness above 1,000 ppm, alkalinity over 120, and a pH over 7.8. Keeping your pool’s calcium levels, alkalinity, and pH levels within the normal, safe ranges is the best way to prevent calcium lumps and other problems, including damage to the pool surface.

It is generally not recommended to place a pool directly on grass. Doing so will kill the grass underneath, and the surrounding lawn may also be damaged by heavy foot traffic and splashes of chemically-treated water. For best results, create a clean, level surface by removing the grass and debris. You can then install a sturdier base using materials like sand, a concrete pad, or solid foam.

The average 12-by-24-foot in-ground pool costs $48,500, but depending on the features and materials, prices can trend even higher. You’ll spend less on a rectangular vinyl or fiberglass pool than on a concrete pool in an elevated style (think infinity pool or lagoon pool). Added features like heating, lighting, diving boards, or decking will increase your overall cost.

You don’t need to drain the whole pool to patch a pool liner, but be prepared to dive in with your swimsuit and goggles to patch a leak below the water level. By draining the pool, you can actually expose the liner to more harsh conditions, like wind and sunlight, that cause the tears to worsen. It’s best to use the ink test and waterproof patches or tape to identify the leak and patch it up.

You can place a pool alarm on the surface of the water or mounter underwater with motion detectors. Alarms placed on the surface will alert you if it detects wave movement. If mounted below the surface, known as "sub-surface,” the alarm detects changes in water pressure.
