How to Fully Drain a Pool
- 1). Throw (shut-off) the breaker in your breaker box controlling the pool's water filter. You might have to throw several of them to see which one controls the filter.
- 2). Locate the auto top-off valve on your pool's water pump. It should consist of a stamp into the metal or a label that reads "auto-top" or "auto-fill." The top-off valve monitors your pool's water level and fills it as necessary, as water evaporates or if water levels dip.
- 3). Open the "sewer clean-out port" near your home's incoming and outgoing water main. The “sewer clean-out port" consists of a narrow water main leading to your home's primary outgoing sewage line and has a white plastic or metal cap on top of a 3-inch to 4-inch pipe opening.
- 4). Thread your rubber hose into the sewer clean-out port.
- 5). Attach the 3/4-inch rubber hose to your multispeed submersible pump. You need the 3/4-inch rubber hose because the pump's intake valve will not reach the actual bottom of your pool and will leave a layer of water across the surface of your pool or in the deep end. The hose will rest closer to the bottom and suction up more water.
- 6). Turn on your submersible pump and lower it into the deep end of your pool
- 7). Set the pump speed on medium.
- 8). Monitor your home's sinks, toilets and tubs for backflow. If you experience backflow, lower the pump speed.
- 9). Squeegee the water toward the deep end, if you have one, using the long-handled squeegee. If you don't have a deep end, squeegee the water toward the pump until the pump suctions all the water it can.
