It is most likely that if your two feed pumps running at the same time cannot draw the pickling solution that after two years of use they are a bit tired and just can't create enough vacuum to draw the solution up through the intake service. Some times on these older systems they can also lose their prime and they can get air locked. One trick is to hold the bucket of pickling solution just above the level of the intake service port your pickling hose is attached to. This way there's a bit of gravity feed as well and with both pumps running it should start the intake and flow. Of course this is always done with the pressure relief valve on the Clark pump open about 3/4 to 1 full turn. If this does not solve your problem let me know and we can go from there. I've worked on more Santa Cruz units than most. It was the very first Spectra unit I ever worked on. I used to be known in my earlier days as the Santa Cruz King because no one else really wanted to work on them because they are certainly a pain to work on with that un-gangling front cover. You have the basics of a Cape horn Extreme. If you ever wanted to re arrange it and get rid of that white box it is all in I could help you with that as well. They're much more enjoyable when you can easily get to all the parts
Thank you Tellie, you certainly appear to be the most qualified guy on the planet to help with my Spectra Santa Cruz!
I don't have enough room in the engine
room to put the bucket above the service port, so my work around was to use a turkey
baster to fill the intake hose to prime it. Didn't work, and putting my finger over the hose (as I've done before to test successfully) there was zero suction happening.
Given that all components are new, there are no leaks, and the unit works fine to produce water
, any other ideas?
Regarding the Cape Horn Extreme, is there a way to re-purpose my new pumps, membrane and rebuilt Clark pump or would I need to buy the whole kit and caboodle.
Thanks so much for your help!
