Glad to see you got that fixedUpdate on the pump issue. I pulled the check valves on the pump itself and 2 of the 6 had dirt in them. Cleaned them out and no more pulsating. Thank you Jason for that idea.
As for the chemical feed I tried to prime it and still not working. I will fool with it some more tomorrow. Pull both lines off again and check for cracks and leaks as well as the chemical meter. I did notice there is water in the meter now just cant get any flow or bubbles going in it.
