I am rebuilding a spectra water
maker and trying to determine whether to use a 21" or 40" membrane and therefore one or two pumps.
It seems the cost of the membranes and housing is basically the same, but my chief concern is extending the time of the Clark pump between servicing.
My pump was just rebuilt/replaced for the previous owner last year.
Does anyone know what it costs to have a pump rebuilt? I see the seal kit alone selling for $490! I know water
maker water is said to be expensive, but it seems like you maybe getting into really expensive water depending on how often you need a seal kit?
So basically, does the running of two pumps double the frequency of rebuilds? Or is an hour on the pump the same either way and maybe the gallons made per rebuild
is much higher when using 2 pumps?
Can anyone share an approximate gallons made/maintenance cost ratio for say a 2-5 year period?
