Will homeowners insurance cover damage to an in ground swimming pool pipe?

the swimming pool is insured under the 'appertinate' (sorry can't remember the correct spelling) or 'other' structures portion of most policys........the same 'perils' apply.......as do the same 'exclusions' will depend on why or what caused the damage? sudden and accidental, or gradual deterioration?.......... most if not all h/o policys exclude some parts of 'under ground' Plumbing..........more info and maybe i can help more........
