    Spa/Pool Drainage

    Spa drains part way once the pool motor/pump automatically shuts off. Any ideas why

    There should be a check valve on the return line going to the spa. If that check valve is missing or isn't working the spa will drain down to the level of the pool any time the pump is off.
