Spectra Watermaker issues…..help!

[SV Wildgoose]

Thanks. Cannot find any sign of water leak of any size but think you are right that air is getting in somewhere. Umm. Puzzled as to how to find out where…

Hello Galleta - It sounds your watermaker is reciving tidal changing feed water (tempature & salinity spikes) from vessel changing positions, currents, tides, ect...
I say this, as a membrane does not go from making good water online to high salinity due to a small leak, the high salinity alarm would occure at a restart when off for hours, days... If you were making water and got a feed water spike, colder, more saline water, then you can get a hi salinity alarm and a week pipe joint starts leaking as it requires more pressure to make design production.
Be aware this Energy Recovery Technology (Clark Pump) is tempermental to sudden temp and salinity spikes in feed water before the Spectra pressure & safety cutout can react, or the feed salinity just staying below the cutout, but effecting the membrane product salinity. Being all clean filters, pumps stronk and feed to the clark pump is free of air! Hope this helps.
