Tools for Water Removal

For small amounts of water, a simple sturdy squeegee can be very effective. You can direct the water towards a drain or the edge of the roof. A wet/dry vacuum is another excellent tool for smaller jobs. For larger areas, consider a sump pump or a water-moving pump.

If the water is shallow, use a squeegee to push it towards the nearest drain. Work in sections. For slightly deeper water, a wet/dry vacuum can suck it up quickly. Make sure the vacuum is rated for water use. Empty the vacuum frequently.

When to Use Pumps

For significant amounts of water, a sump pump or a dedicated water pump is your best bet. These can move water much faster than manual methods. Position the pump in the deepest part of the pool. Direct the discharge hose away from your home’s foundation. Pumping water efficiently is key.
