Step-by-Step Guide to Emptying Your Pool the Right Way
To safely drain your pool without causing damage, you need the right pump, a safe place for the water to go, and careful timing. Draining a pool the wrong way can crack the surface, shift the structure, or damage nearby property. In some areas, even heavy rain can affect results. Following the correct steps helps protect your pool and your yard.
Quick Answer Before You Start
Pool draining is not just about removing water. You must lower the water in a controlled way, release pressure safely, and avoid leaving the pool empty for too long. Groundwater under the pool can push up if the pool is left dry. Heat from the sun can also crack plaster or vinyl. The key is planning and timing.
What You Need Before Starting
Before you begin, gather the right tools and check local rules. Some cities have guidelines for pool services and water discharge.
- Submersible pump with discharge hose
- Garden hose for rinsing
- Access to an approved drainage point
- Protective gloves and rubber boots
- Hydrostatic relief valve tool, if your pool has one
Also check the weather. Do not drain your pool right after heavy rain. Wet soil increases pressure under the pool shell.
Step-by-Step Process for Safe Pool Draining
-
Turn off pool equipment at the breaker panel.
-
Place the submersible pump in the deep end of the pool.
-
Run the discharge hose to a safe drain area.
-
Start pumping water out slowly and monitor progress.
-
If your pool has a hydrostatic relief valve, open it carefully once the water level is low.
-
Do not leave the pool empty longer than needed for cleaning or repairs.
-
Refill the pool as soon as work is complete.
Stay nearby during the process. Check water flow and watch for soil movement around the deck. Most residential pools drain within several hours, depending on size.
Common Mistakes to Avoid
Many problems happen because people rush or skip steps. Here are mistakes that can lead to expensive damage:
- Draining during hot midday sun
- Leaving a vinyl liner pool empty too long
- Not checking groundwater conditions
- Sending water into a neighbor’s yard
- Using the pool pump instead of a submersible pump
Using your filter system for pool draining can burn out the motor. A separate pump is safer. Another mistake is ignoring small cracks. When the pool is empty, pressure shifts. Cracks can widen if ignored.
Why Groundwater Is A Serious Concern
Concrete and fiberglass pools sit in the ground like boats. When full, the water weight holds them down. When empty, strong groundwater can push them upward. This is sometimes called pop-out. It can lift the entire shell and destroy plumbing lines.
If you live in an area with a high water table, draining without checking soil moisture can cause major structural damage. A pool professional can test conditions before you start.
How Long Should A Pool Stay Empty?
As short as possible. Most pools should not remain empty more than a day or two. Sun exposure dries plaster and causes shrink cracks. Vinyl liners can wrinkle or shrink. Even fiberglass pools can shift under pressure.
If resurfacing or major repairs are planned, timing matters. Crews often schedule refill immediately after work is finished. Keeping the surface damp during repairs can also prevent damage.
When to Call A Professional
Some situations require expert help. These include:
- Visible structural cracks
- Unknown groundwater conditions
- Large commercial pools
- Severe staining that needs acid washing
- No safe drainage access point
Professional pool draining reduces the risk of surface damage and structural issues. Technicians use proper pumps and know how to monitor pressure changes. They also follow local disposal rules.
