After the better part of a week with a quiet pump, I got protests from it again today in the squawking sound, both times while backflushing. This leads to several questions:
For checking an air leak... (1) Do I simply need to focus up-line from the pump (such as the water tube, rubber elbow fitting, and the clamp that seals the fitting to the pump), or do I need to troubleshoot things down-line also, like the tube going out of the OPV or the deaerator back to the reservoir or the tubing that goes from the pump to the boilers? (2) Are there ways to check for an air leak other than simply visibly inspecting tubing, removing and reconnecting tubes to be sure they have a good seal? For checking other things... (3) Are there other things, besides possible air leak, that I should be on the look out for? Overall, I'm thrilled that I'm getting much improved espresso flavor. But draining and repriming the pump frequently in order to keep oxygen from oxidizing isn't sustainable.
