one hour in a bucket at 11PSI…not a bubble to be seen… Manipulated the shifter, wiggled it a bit…turned the shaft, wiggled it a bit too. No bubbles at all.
1.) interesting note (above) about testing with lower, not higher, pressure. But I’m closed up for the day. I’ll try that tomorrow night.
2.) when I initially put it in the bucket, I had bubbles where my hose fitting went into the housing. I had to tighten it quite a bit more than I would have suspected. This whole thing could have been as simple as a bad seal on the upper plug…
3.) If re-testing with lower pressure doesn’t reveal anything, I’m ready to declare the seals to be OK and chalk this up to a bad seal on the plug.
Am I missing anything?
