Pool Cover Drain Box (Gravity Based Vacuum Pump)

This is a simple pool cover pump - which uses gravity to siphon off water or melted snow off the pool cover, without a powered pump. For those of us that live in northern climates, a cover pump comes in handy to drain water, or melted snow/ice off a pool cover. Unfortunately, electric pumps too often die if they are left on the cover and get “iced in”. For years I had used my dead pump (which I cut the electrical cord off of) as a gravity feed pump, by connecting a 50 foot hose to the hose connection on the pump. The plastic finally cracked, so this is a simple replacement. This type of gravity feed pump requires that there be no air leaks at the top of the box, at the hose connection, and in the hose itself (until the end of the hose is below the height of the water that you are trying to remove). On one build plate I have combined the hose connection (taken from bdwilson - Fibro Pool Submersible Pump… model) and combined it, a cover, and the box to ensure no air leaks. This may be ac
