Inspection was limited to those areas which are above ground or water level. The only way to detect an underground leak in a supply line, buried pipe fitting, or pool surface crack is by observation of the persistent and continuous loss of water from the pool over an extended period of time. Purchasers are encouraged to ask sellers about the existence of any past or present leaks in the pool, spa or associated equipment. Pool filtering devices are not disassembled to determine the condition of any installed filter elements. Operation of time clock motors thermostatic temperature controls cannot be verified during a visual inspection. Testing of backflush mechanisms is beyond the scope of this inspection. Pilot lights of LP gas pool heaters are not lit during the inspection.
