Product details

The Pleatco PJ120 is the replacement cartridge for the Sherlock filter, carrying 120 square feet of pleated media. It measures 10 inches across the outside diameter and 20-1/2 inches long.

Media area is the whole point

A cartridge filter gets its long cycles from surface area. Fitting an element that is short on media means the filter loads faster, pressure climbs sooner, and the lid comes off more often than it should. Replacing like for like keeps the filter running the way it did when the system was new.

Cleaning and replacing

Write down the pressure gauge reading with a clean cartridge in. When it climbs roughly 8 to 10 psi above that, pull the element and wash it thoroughly. When a good wash no longer brings the gauge back down, or the pleats are matted, split or permanently gray, fit a new cartridge.

Questions and answers

What people ask about this product, answered by our pool techs.

What size is this cartridge?
10 inches across the outside diameter and 20-1/2 inches long, with 120 square feet of media.
Which filter is it for?
Pleatco lists PJ120 as the cartridge for the Sherlock filter. Measure your old element before ordering if you are not sure which filter you have.
Can I run a smaller cartridge in the same housing?
Not sensibly. Cutting media area shortens the run between cleanings and pushes the pump harder, so match the 120 square foot element the filter was built around.
How long should a cartridge last?
It depends on hours run and how heavy the debris load is. Wash it when pressure is 8 to 10 psi over the clean reading, and replace it when a wash stops restoring that reading or the pleats are matted or torn.
