Pentair U-3 Skimmer 1.5" MPT Check Valve is a check valve used to help direct flow through pool, spa, or water-treatment plumbing while reducing unwanted backflow through the line. Correct check valve selection matters because connection style, thread type, spring rating, and body size all affect how the valve installs and how it performs in the system. This item is best used when replacing a worn, leaking, sticking, or incorrectly sized valve in the application shown. Match part number 08655-0007 and verify orientation, plumbing size, and equipment layout before cutting into existing pipe or reinstalling fittings.

For best results, compare the replacement against the original part before disassembly is complete. Pay close attention to size, rating, connection, and model details shown in the title, material, color, or construction notes, because those details are usually what separate a correct repair part from a part that appears similar but will not install correctly. This product is intended for service and maintenance work where dependable fit matters more than guesswork, and it is especially helpful for technicians or homeowners trying to repair existing equipment instead of replacing a full assembly.

Helps control one-way water flow and reduce reverse flow through the plumbing line.
Selected by connection size, thread/slip style, spring rating, and application requirements.
Use part number 08655-0007 to compare against the existing valve or service parts list.
Helpful for equipment pads, sanitation systems, returns, skimmers, and specialized plumbing layouts when compatible.
Install in the correct flow direction and pressure-test the repair before returning the system to normal use.
