1. An inflatable pool comprising:
- a top wall;
a bottom wall;
an internal wall;
an external wall;
an inflatable air chamber defined by the top wall, the bottom wall, the internal wall, and the external wall;
a water cavity defined by the bottom wall and the internal wall;
an air pump; and
an air passageway that delivers air from the air pump to the water cavity of the inflatable pool, wherein in an area located between the air pump and the external wall of the inflatable pool, the air passageway includes;
a first check valve that is biased closed to prevent a backflow of water from the water cavity to the air pump and is opened under pressure from the air pump, the first check valve having a hemispherical seal;
a second check valve that is biased closed to prevent a backflow of water from the water cavity to the air pump and is opened under pressure from the air pump, the second check valve having a hemispherical seal; and
a drain valve that is biased open to drain any water from the air passageway and is closed under pressure from the air pump.
