Hi Tellie, CF forum members sing your praises as the Spectra Guru, so I thought I would reach out with a problem I'm stuck with. I have a Spectra Santa Cruz model that was recently professionally reconditioned (new membrane and pumps, rebuilt Clark, etc. and I can't get the pickling/cleaning procedure to work because it won't suck anything from the bucket. It worked before, and I've checked all the valves, etc and can't find anything wrong. I even tried work-arounds, such as bypassing the service valve and no joy. No leaks, good pressure. Any ideas?
