Flushing your lines for pool opening

Don’t Forget to Flush Your Pool Lines This Spring

You shocked the water. Balanced your pH. Cleaned the filter. You’re probably feeling pretty good about your pool opening checklist.

But there’s one step that often gets overlooked — and it could undo all that hard work: flushing your pool’s plumbing lines.

Over the winter, water sitting in the lines can collect all kinds of nastiness — debris, bacteria, and even algae spores. It’s even worse if you used antifreeze or left stagnant water sitting there for months. When your system kicks back on in the spring, all that gunk can get pushed right into your clean water.

Here’s how to properly flush your lines before balancing your water:

  • Run the pump with the waste setting first, if available
  • Add a line flush cleaner designed specifically for pool openings
  • Let the system circulate with fresh water for a few hours before adjusting chemicals

This simple step gives your pool a real clean slate. It’s not just what’s floating on the surface — your water starts behind the scenes, deep in the pipes. Flush it out, and your water quality will be better all season long.
