Can Chlorine Tablets Damage Pool Equipment?

Many pool companies still place chlorine tablets in skimmers. Learn why this practice can damage plumbing, pumps, heaters, and pool surfaces—and what should be done instead.

Many pool owners assume that all pool service practices are the same, but one common shortcut can potentially cause expensive damage to your pool system.

If your pool company is placing chlorine tablets directly into your skimmer or pump basket, it may be time to ask some questions.

Chlorine tablets are highly concentrated and acidic. When they are placed in the skimmer, water carrying that concentrated chlorine travels directly through your pool’s plumbing and equipment. Even worse, when the pump shuts off, highly chlorinated water can sit in the pipes and equipment for hours until the system starts up again.

Over time, this can contribute to premature wear and damage to:

  • Underground plumbing lines
  • Pump seals and O-rings
  • Heaters and heat exchangers
  • Filter components
  • Pool plaster and surfaces, particularly around the main drain

Chlorine tablets placed in a pool skimmer and pump basket can damage plumbing, pumps, heaters, and pool equipment over time.

While chlorine tablets can be an effective sanitizer when used correctly, they should be applied in a way that protects your pool equipment and maintains proper water chemistry.
