Nice. How did you decide how much accumulator you needed? What is the leak rate with the setup shown in the video? I.E. how long does it take for the pressure to rise 1 psi?
I like the accumulator approach. It lets you run a smaller pump as long as the leak rate isn't too high. Nice job.
It always makes me shake my head when someone comes up with something innovative and posts a contribution and then it gets picked on for irrelevant details. Thanks for all your work and for taking the time to share it! This is a nice contribution to the community.
If you get a chance to check the leak rate with various materials and setups I would appreciate the info. Also, if you could show some close up shots of the seals and any info regarding materials used.
Thanks again and great job.
