    Finally I received the correct size, which works fine.

    I can return my previous order, that was ordered based on their description of 6", that I thought was the measurement of the 'inside diameter' of the bottom. Actually, for all future buyers, please measure the 'outside' measurement of the base, to receive the correct flow valve.
