Spring Check Valve - 27001-0130S
when i first got my starite filter assembly it did not have a spring-check valve. do i necessarily need one for my system to operate correctly?

The check valve would be necessary if you needed to prevent water from back flowing into the filter, ie the water level of the pool is above the pump, which is common with hot tubs and spas or solar water panels. A check valve is not a requirement to install a filter.

Shawn, I would recommend inspecting the elements inside fo the filter. They are what typically cause d.e. going back into the pool.

The old Spring Check Valve in my filter is stuck and I can't remove it with any of the tools that I have. Is there a special tool that I need to remove the Spring Check Valve? Thank you for your time.

Unfortunately there is no tool to remove the check valve. If you can make some kind of a 2-1/2" wedge, you may be able to get it on 1 side of the spring & grab 2 of the notches to get it to start to unthread.
