Frequently asked questions
How do I measure for a replacement liner?
Measure the pool's length and width at the widest points, then the wall height and the depth profile. Bead type matters as much as size: overlap, beaded and unibead liners hang differently and are not interchangeable.
What is the part number for this liner?
Pentair lists this liner under part number 79200100. Quote 79200100 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
What is a unibead liner?
A unibead can be installed either as a standard bead in the track or converted to a J-hook that hangs over the wall, which lets one liner suit two installation styles. Check which method your pool's track supports before ordering.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
How long does a vinyl liner last?
Liner life is driven by water chemistry and UV exposure more than by age. Sustained low pH, high chlorine and letting the water level drop and expose the vinyl to sunlight are the fastest ways to shorten it.
Is there a warranty on this liner?
It carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
