Pool Loses Water During The Winter

I lower the water to below the skimmer, add winterize chemicals and cover my pool in the fall. By the time I am ready to open it in the spring I have less than 1 foot of water remaining in the pool.

The first time this happened I thought it was a leak. I couldn't find a leak so I filled the pool and it was fine all summer. This has happened the last 3 years.

In spring it's very difficult getting the leaves and water out of the liner. I think the weight of the accumulating water and leaves is forcing the water out somehow. Do you think I could try a only using a mesh cover?



Hi Nancy. It sounds to me like the pool has a slow leak. As you said, the extra weight put on the water during the winter probably forces the water out faster than in the summer. If you can't find any signs of holes in the liner it's probably those hard to find pin holes.

If this condition does not bother you during the summer months then I would recommend trying to keep it as full as possible during the winter months. Try to add water to it, as needed, to keep the level up to where it should be. This might help.

As the leaks get worse you will more than likely be replacing the liner then the problem is solved.

These pages might help in the future.
