Sorry, I lost
track of this thread, been really busy of late.
Just to clarify a few points. The Z-ION is designed to eliminate the required weekly flushings and extends the recommended fresh water flush to 30 day intervals for watermakers that are not being used and are not pickled between uses. I've installed many of these Z-ION systems. They absolutely do work
. I installed and tested the first Z-ION system sold to the public. This boat
was for a very good client of mine. He is a great guy but he likes the best and newest of everything on his Outremer
. If he added new electronics
and six months later a newer updated version came out he replaces it. There is always work happening on his boat
. He's just one of those guys. But because of this his boat many times had the power shut off for the work being done and when the power was turned back on the other trades would either ignore the watermaker setting or just did not know how to re-set it. So I would replace the membrane on this boat 3-4 times a year. This was a great client to test this on as he allowed me to test this my way. Long story short, he still has a lot of work done and many times the watermaker is shut down for three months at a time. I have yet to replace the membrane installed along with the Z-ION. Spectras time line is going to be 30 days between flushes, but I seen it go 90 days with no ill effect on the membrane. The Z-ION is a bit more complicated than a simple charged rod. Remember it is not only designed to let the system go longer between fresh water flushes but it also protects the rest of the system from Anaerobic growth.
What needs to be decided is what type of cruising do you do. For someone who lives aboard and uses their watermaker every week then it probably doesn't make sense to add a Z-ION system. For those that sporadically use their boats and watermakers it can make a lot of sense.
