Most in-ground pools should be completely drained and the water replaced every 5 to 7 years.
Exactly how often will depend on your maintenance schedule, how frequently the pool is used, and what kind of environment your pool is located.
When most people think of draining a pool, they are thinking in terms of draining a bathtub.
Draining a pool is probably one of the biggest mistakes a homeowner can make because it is extremely dangerous.
There are only very few occasions you will ever need to drain a swimming pool.
1. To dilute the Total Dissolved Solids (TDS) or even stabilizer. These typically only require a partial draining.
2. If you have a repair to be made, this can be a reason to drain a pool.
3. For most cleaning, even when your pool looks like a toxic waste dump, you should never drain the pool. (If absolutely necessary, a partial drain at best)
Why Draining a Pool Is Dangerous:
When one drains the pool and there happens to be water under the shell (like in the rainy spring when people want to clean up the pool) the entire pool shell can heave.
This is because the water under the pool creates an upward hydrostatic force (through buoyancy) and the pool is lifted out of the ground.
Note: Always consult with a professional before tampering with the working components of a pool.
