Pool leak repair
Pool main drain leak repair
The main drain sits at the deepest point of the pool, so a leak there keeps draining the pool until it is fixed. Pro Pool Team dives the pool to dye test around the drain, plumbing tests the drain line, and repairs the drain or its line under our Florida contractor license.

Signs of a main drain leak
- The pool keeps losing water even when the water level is below the skimmer, lights and returns.
- The water loss continues with the pump off.
- Dye is pulled toward the drain cover or the edges of the drain sump during a dye test.
Why main drains leak
The drain body is set into the floor of the pool shell. Over time the seal around the drain can crack, the drain line under the pool can break, and old drain parts can fail. Ground movement under the pool shell can also stress the drain line.
How we repair main drain leaks
- Sealing around the drain sump from inside the pool.
- Repairing or isolating a broken main drain line.
- Replacing drain covers with compliant anti-entrapment covers when the work requires it.
In Florida, a contractor must hold a license that starts with CPC to remove or replace main drain covers. Pro Pool Team holds license CPC1460553.

Frequently asked questions
Can you fix a main drain leak without draining the pool?
Many main drain leaks can be found and sealed underwater by a diver. Some line repairs need more work, and we explain the options after the leak detection.
Who can replace my main drain cover?
In Florida, removing or replacing a main drain cover requires a licensed contractor whose license starts with CPC. Ours is CPC1460553.
Why does my pool keep losing water below the skimmer?
If the water keeps dropping below the skimmer, lights and returns, the leak is lower in the pool, often at the main drain or its line.
