At the bottom of the pump, where it goes through a small hole into the tank, there is a small seal around the pump. Mine cracked and fell off which allows the fluid to drain out quickly. You can unplug the pump unit and go to a Hardware store, find a small seal or gasket in the plumbing dept, that fits snuggly around that end of the pump. Apply some sealant and press it in to the hole.
