I use a different setup with strainers before the tips (AI110) which won't accept strainer/checkvalve. Typically the ball check valve strainers are set to about 5lb.PSIG. THESE DO NOT LAST FOREVER. That spring gets weak and strainer/check valve just need to be replaced. Rittenhouse has them or sometimes you can find at Tractor Supply. I used a 100 mesh Brass checkvalve strainer.
We all are merely gleaners from the masters who were here before us.
