Pentair FAS-100 Front Access Skimmer Basket | 85003900

Frequently asked questions

How do I identify my skimmer model?

Skimmer bodies are identified by the throat width, the lid diameter and the port configuration. The model name is often moulded into the underside of the lid or the collar - check there before measuring.

What is the part number for this skimmer?

Pentair lists this skimmer under part number 85003900. Quote 85003900 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.

Why is my skimmer not pulling water properly?

The usual causes are a full basket, a weir door that is stuck or missing, a partially closed valve, or an air leak on the suction side. Low water level is the single most common explanation - if the water drops below the throat, the skimmer draws air instead.

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.

Are skimmer lids and baskets interchangeable between brands?

Rarely. Lid diameters and basket collars differ between manufacturers and between generations of the same manufacturer's skimmer. Measure the opening on your skimmer and compare it with the dimensions listed above.

Is there a warranty on this skimmer?

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.
