Pool Cover Pumps & Submersible Water Removal

Standing water is what destroys winter covers. A few inches of rain and snowmelt across a 20' x 40' cover weighs thousands of pounds, and that load stretches seams, pulls grommets, and drags leaves and silt straight into your pool the moment the cover gives. A pool cover pump keeps the top of the cover clear all winter. PST Pool Supplies carries submersible cover pumps, utility pumps, and non-electric siphons from Little Giant, Superior Pump, Danner, and Swimline.

For routine cover duty, a dedicated submersible cover pump is the right tool. The Swimline 5420 (250 GPH) and 5440 (500 GPH) and the Danner Cover Care CC350 and CC500 all run on a 25 ft cord with a 3/4" garden hose discharge, so you can drop one on the cover and run the hose off the deck. The Little Giant PCPK-N kit ships with 25 ft of discharge tubing included. If you want more throughput, the Superior Pump 90091 mag drive moves 810 GPH with no seals to fail. Danner's full Cover Care line is at Danner Manufacturing, and Superior's specs are at Superior Pump.

For bigger jobs there are true submersible utility and sump pumps: the Little Giant 5-MSP Water Wizard (1/6 HP, 1200 GPH), the Little Giant 6-CIA-RFS Big John automatic (1/3 HP, 2760 GPH), and the Superior Pump 92788 automatic (3/4 HP, 4800 GPH) or 91875 manual main drain pump (1/2 HP, 5580 GPH) for draining a pool down or emptying a flooded pit. Where there is no power at the pool, the Swimline 5436 Cover Saver siphon kit and the Thirsty-Mate 136PF6 hand bilge pump move water without electricity. The collection also includes the Air Supply Cyclone Pro 3 HP winterizing blower for line blowouts. Pair a pump with your pool cover and see the complete pool winterizing supplies range. Little Giant pump documentation is available from Franklin Electric.

Get a pool cover pump on the cover before the first heavy rain — replacing a stretched-out winter cover costs many times what the pump does.

Frequently Asked Questions

What size pool cover pump do I need?
For routine rain and snowmelt on a residential cover, 250–500 GPH is plenty — the Swimline 5420, Swimline 5440, and Danner Cover Care CC350/CC500 all sit in this range and discharge through a standard 3/4" garden hose. Step up to the Superior Pump 90091 at 810 GPH if you get heavy sustained rainfall or have a large inground cover. Higher-flow utility and sump pumps in this collection are for draining a pool down or clearing a flooded pit, not for sitting on a cover.
What is the difference between an automatic and a manual cover pump?
An automatic pump senses water and cycles on by itself, so you can leave it on the cover all winter unattended — the right choice if you are not checking the pool weekly. A manual pump runs whenever it is plugged in, which means it will run dry if you forget it. Manual pumps are cheaper and fine if you are hands-on, but a mag drive manual like the Superior 90091 tolerates dry running far better than a standard seal-and-impeller design.
Can I leave a cover pump on the pool all winter?
An automatic cover pump, yes — that is what it is designed for. Set it near the middle of the cover where water naturally collects, run the discharge hose well away from the pool so it does not drain back, and check it after every big storm and freeze. The main winter failure is the pump icing into the cover, so if a hard freeze is coming and there is little water on the cover, it is worth pulling the pump. Keep the cord connection off the cover and out of standing water.
Do I need electricity to drain my pool cover?
No. The Swimline 5436 Cover Saver siphon kit uses gravity to pull water off an above ground cover with no power at all, and the Thirsty-Mate 136PF6 hand bilge pump moves about 13 GPM by hand with a 72" hose. Both are good options when there is no outlet near the pool, or as a backup for when an electric pump fails midwinter. A siphon needs the discharge point to sit lower than the cover to work.
Will a cover pump damage my winter cover?
Not if it is set up properly. Dedicated cover pumps have flat, wide bases specifically so they spread their weight and do not chafe the cover fabric. Problems come from putting a heavy sump pump with a narrow footprint or sharp feet directly on a cover, or from letting the pump sit on a fold where it works a crease. If you are using a utility pump on a cover, set it on a small piece of plywood or a cover pump pad to spread the load.
