Well I replaced the pex, 1/2 accuflex tubing and SureFlo filter with clear 1/2 id tubing from tank to pump which immediately solved the trickling flow problem. Once the Sureflo was out in the open I could see it looked blocked. I tried running water through it but nothing. Removing the pex section is where there's a brass T, one side goes to the pump, the other side goes to the drain. There is a plastic knob to the right of the brass T that exits out the drain. I couldn't get the plastic valve to open. I'm wondering if I can leave the clear tubing instead of the accuflex, brass and pex setup.
