In-line filter

[Bricks]

Hello. My automatic has been leaving a smear job and I’m pretty sure a piece of rust from the line was holding the check valve open on the PS, I was gonna replace it with poly but 250psi is the strongest I could find. Is there an inline strainer I could put right before the check valves for the SFR and the Presoak? I’m confused in that I know the flow should go in that direction, but doesn’t it have a little resistance in the check valve? Thanks for any assistance.

Do you mean before the solenoids? Check valves prevent backflow, and a failed one shouldn't allow presoak to come through.

Thank you! That ought to do the trick. The lines going to the check valves in the attic are rusty, so I’ll put these on the ends before the check valves.
