You can probably cound on no coverage due to neglect or incompetency.
Truly depends on your insurer and what plan you have. But it should.
No. This sounds like a manufacturer or maintenance issue. Something is wrong with the pool itself or with the way it was installed as the earth behind pool walls has washed away making it loose support and fail. For a homeowners policy to pay for damages the damage must be the fault of a covered cause. I can't see how the damage you are describing could be from a coverer cause. Homeowners insurance is not made to cover maintenance issues or manufacturer defects. First I would contact whoever installed the pool. If it has been past the warranty period I would check with a professional to see what the cause of the damage is first.
There is no "swimming pool" insurance. There are however riders available from some insurance companies that can be added to your homeowner's policy.
Depends on HOW the damage occurred. Your above ground pool is normally covered as 'personal property' under your homeowners policy for the listed perils. See Coverage C- Personal Property for the list of covered losses.
Well the average depth of a home installed swimming pool is about 6 ft
It just depends on the insurance company underwriting guidelines. Some companies will not accept pool risks with a slide, some will not accept diving boards. If it is determined that your risk does not qualify for coverage under the guidelines then they can cancel your policy.
The kinds of cheap swimming pools that are available are the rubber swimming pools that kids can play in. The ones that have to be installed in backyards are expensive.
Homeowners policies are not all the same; you can include an above ground swimming pool in such a policy, but the policy will have to state that this coverage is included. Normally, a home owners policy only covers things that are inside the home, not things that are in the back yard. Read your policy, it will tell you what is covered. Or if you don't have a policy, you can get any kind of insurance you like - but everything you insure will add to the cost of your monthly premium.
High chlorine levels or a salt system installed at location.
I don't see any need for liability insurance in the case you described. In cases where you have a homeowners association or a condo owners association and they own common property such as a swimming pool, parks, roofs, sidewalks, etc. then they would have a need for both property and liability insurnance to cover these areas. This is what you dues are in place to pay for as well as maintenance.
The damaged pool should be covered by home owners insurance if you had the pool added to the insurance for coverage
