Removing water from an inground pool typically involves using a submersible pump, although siphoning or even the pool's own filtration system can sometimes be employed for smaller amounts. Here's a breakdown of the process:
Using a Submersible Pump:
This is the most common and efficient method.
-
Acquire a Submersible Pump: You can rent or purchase these at most hardware or pool supply stores. Ensure it's designed for removing large volumes of water.
-
Place the Pump: Put the submersible pump in the deepest part of your pool.
-
Connect the Discharge Hose: Attach a garden hose (or a larger diameter discharge hose for faster draining) to the pump's outlet.
-
Position the Discharge Hose: Run the other end of the hose to a location where the water can safely drain away from your property and your neighbor's. Avoid draining into the street unless permitted, as it can clog storm drains. Consider draining to a sanitary sewer cleanout if allowed by your local municipality.
-
Plug in the Pump: Plug the pump into a Ground Fault Circuit Interrupter (GFCI) outlet.
-
Monitor the Water Level: As the water level drops, reposition the pump if necessary to ensure it remains submerged. When the water level gets low (below the skimmer opening), it's crucial to monitor the pump. You don't want the pump to run dry and pull air, which can damage it. Some pumps have automatic shut-off features.
-
Address Remaining Water: Once the pump removes the majority of the water, a shop vac or similar device can be used to remove any remaining puddles.
Alternative Methods (for smaller amounts of water):
-
Siphoning: For minor water level adjustments, a garden hose can be used to siphon water out. Submerge the entire hose in the pool to fill it with water, then hold both ends underwater while placing one end over the side of the pool at a lower level.
-
Pool's Filtration System (with Waste Setting): Some pool filters have a "waste" setting that bypasses the filter and pumps water directly out. This method is generally slower than using a submersible pump and is not suitable for draining the entire pool, but it can work for lowering the water level.
Important Considerations:
-
Groundwater: Before draining your pool, be aware of the groundwater level in your area. Draining a pool in areas with high groundwater can cause the pool shell to "float" or crack due to hydrostatic pressure. A hydrostatic relief valve can help, but professional advice is always recommended.
-
Local Regulations: Check with your local municipality for any regulations regarding draining a pool, especially concerning where the water can be discharged.
-
Winterizing: If you're draining the pool to winterize it, remember to properly prepare the pool for freezing temperatures after the water is removed.
