What Is a Pool Cover Pump?
A pool cover pump removes standing water from a pool cover, helping prevent sagging, overflow, and heavy buildup after rain, snowmelt, or debris.

The purpose of a pool cover pump is to clear the standing water that can accumulate on top of your pool’s cover. It is a small device designed for this task, and in doing so it prevents the kind of excess water collection that leads to sagging or puts undue stress on the cover in wet weather or when the snow melts.
What is its function?
Do not confuse a pool cover pump with the circulation pump for the swimming pool itself. The latter is for filtering; the former is placed on or by the cover to move water off it.
Routine maintenance is about getting rid of what has built up after a storm or from melting snow. Left alone, that water will only trap leaves and other debris, making a mess of the cover and adding to its weight.
Is one necessary?
There is no rule that every pool owner must have one. They are most handy when the cover is prone to holding water. You might want to put one in if you notice:
- rainwater or snowmelt tending to pool
- the cover forming low spots or sagging
- debris settling in the standing water
- the cover feeling heavier than it ought to when you go to lift it
For the occasional bit of water, a little more frequent monitoring will suffice. But if it is a regular occurrence, a pump is a sensible seasonal addition.
How does it differ from other pool equipment?
Your pool’s circulation system is made up of the skimmer, filter, drains and the like, all of which require upkeep per the manufacturer. A pool cover pump is an entirely separate piece of kit. Some are submersible and may be sold as automatic units, but there is variation from brand to brand. In any case, the manual should be followed for everything from cord handling to activation.
Pre-use checks
Before putting the pump to work, take a few precautions:
1. Consult the manual. Make sure you are following the maker’s instructions for setup and operation. 2. Give the cover a once over. Check for any tears or odd sagging that might impede drainage. 3. Get the debris out of the way. Safely remove any branches or leaves before or as you address the water. 4. Look at the electricals. If the insulation on the cord is damaged or the outlet looks suspect, do not proceed. 5. Wear PPE if called for. A wet cover in cold weather can be slippery.
Under no circumstances should one reach into running suction equipment or attempt to make do with an improvised fix on the electrical side.
Time to call in a professional?
If the cover is hard to secure or seems unsafe to be around, or if the pump is tripping breakers and will not start, get a qualified pool professional on the phone. The same goes for suspected damage to the cord or switch, or if the cover refuses to drain despite your efforts.
A pool cover pump is straightforward enough, provided the cover is put in right and the equipment is used as intended. But if the situation with the water or the electricals looks questionable, it is better to let a pro handle it rather than force the matter.
