Main drains for in-ground pools

Crack or break of drain body or of the piping(often after the freeze winter).

Renovation (change of covering/canvas): we take this opportunity toto change the bottom drain.

Very rarely. A replacement is not being considered.that if:

• THE The ground has shifted.(sagging, misalignment that distorts the assembly),
  
• THE The drain body or piping is cracked/broken.(often following the winter frost),
  
• theregrille/lidis damaged (to be replaced immediately for thesecurity).

Yes, as soon as it is obstructed.A blocked bottom drain reduces suction, overloads the pump, and degrades circulation.

To clear a bottom drain, start by closing the skimmer and opening the drain valve to force the pump to draw water through it. If the blockage persists, use a high-pressure water jet to push the obstruction through. In some cases, a technician may need to use a drain snake to completely clear the line. Very low flow or air bubbles often indicate a partially blocked line.

To clean a bottom drain, start by increasing the flow through it: close the skimmer and fully open the drain valve so the pump can draw water from the bottom. You can also use a jet of water to dislodge any fine dirt or deposits that have accumulated in the line. Regular maintenance of the filter and pump also helps prevent debris from building up and clogging the drain.
