How to Identify Compatible Parts for an Older Skimmer Model
Match older skimmer parts by checking the housing markings, measuring the basket and weir, and confirming fit before you buy.

The skimmer body
On an older skimmer, do not simply replace the part that has worn out; start with the housing. Examine the face plate, weir opening, throat and lid frame for any telltale signs: a molded brand or model number, patent marks and the like. You will find these are often what distinguish one model from another of similar appearance.
Safety is paramount before you get to work. Shut off the pump so the system does not kick on while you are lifting the basket or under the lid. Put on your gloves and eye protection as the manual dictates and never put your hands in suction equipment when it is running.
Get your measurements
Size is just as important as the make for older components. Take a tape measure or caliper and put down the numbers for the essential dimensions before heading out to buy. A few good photos from different vantage points can be useful should a pool professional need to double check the part at a later date.
Make a note of: - The height and top/bottom diameter of the basket - Width and depth of the skimmer opening - Weir door dimensions and hinge type - The size and shape of the lid and its locking tabs - How the screw holes are spaced on the cover or face plate
Be sure to record if you are dealing with a standard or wide mouth unit, if there is a handle on the basket, and whether the hardware is set-and-screw or snap-in. Even a minor discrepancy can mean the basket will not seat right or you will not get a seal.
A close look at the original
Do not be swayed by “universal” claims or the fact that a new part appears to be a match. If the old one is on hand, put them side by side. A replacement face plate might be off by a millimeter or two on the screw pattern, or a weir door may be too high.
Look for the same rim profile and wall thickness, a compatible gasket (butterfly or otherwise) and the correct placement of latches. Where the original is warped or cracked, however, you must rely on your photos and the body measurements since a damaged piece is no longer a true representation of the fit.
When to leave it to the professionals
There is no point in trial-and-error purchasing. For obscure models or when the housing is corroded, glued or cracked, take your data to a qualified pro for a definitive answer. Call in an expert if you suspect an electrical fault in the vicinity of the pool gear – swimming is not an option until that is put right – or if debris has become lodged in the plumbing.
Resist the urge to force a part that is only an almost-fit or to put in a brittle old seal. Follow the chemical and equipment instructions, keep the pump off when working on the basket and measure twice. It is the best way to ensure safety and avoid wasting time.
