For years, we have been installing Lakos Sub-K Sand Separators on pumps in all Certified Water Systems. We have invested thousands of dollars in their technology because we believed it would save our clients down time and us money (Certified Water Systems are eligible for a Lifetime Parts and Labor Warranty).
We noticed some wells in Atlanta still continued to produce black sand that would wind up in the cartridge filters we installed at the well head. Here is one such well. As you can see, the material settles really quickly in the sample bottle. It is quite heavy. It should, therefore, be removed by the Lakos Sub-K before it even touches the pump, but it somehow still winds up making its way thru the impellers that the Lakos unit is supposed to protect, and coming out of the well.
Last year, we started building and installing PumpSaver gravel packs for these wells, installing them on the pump end instead of the Sub-K. We have not seen this problem on those water systems.
Gradually, as the Lakos systems fail, we will replace all the SubK units with our own gravel packs. Till then, this is what we have to deal with:Add to favorites
