Columbia Pool Filter



When troubleshooting, always start by confirming that your hoses are connected properly


Problem: "I have sand going into my pool."

Solution: Mostly likely there is a problem with your underdrain (the underdrain is the black "X" shaped piece on the bottom of your tank).  In a normally functioning sand filter, the underdrain strains sand out of the return feed.  If the undrain becomes damaged it can no longer function properly and sand will get in to the return feed and go into the pool.

After removing the sand from your tank, examine the underdrain and look for cracks or enlarged openings.  Replacement underdrains can be purchased from you local pool dealer or from our parts department.
