I have a cottage which has ridiculously rusty, hard water. Previously I asked about putting filters before or after a water softener.

My question here is, Can I put a filter, like an in-line rain-fresh filter, before the jet pump? e.g.

feed from well --> water filter --> pump --> softener --> tank
  • Have the water tested by a reputable water softner company. They will tell you just what you can or should do to your well water. If you have high iron content water, a water softner may not be able to remove all the iron. – d.george May 6 '17 at 11:15
  • Note that carbon/pleated/string-wound filters are not very effective at removing hardness or dissolved iron. – Serguei Dec 6 '17 at 8:08

Not a good idea. It will cause a pressure drop in the suction line, and as the filter plugs the resistance will increase. You can end up cavitating the pump which will erode away the impeller.

  • A decent jet pump + controller should, generally speaking, be able to cope with a clogged suction line without annihilating itself. At residential scale, my gut says the electric motor would die long before generating enough cavitation to damage the impeller. Also a filter should reduce deposit buildup on the impeller = reduced turbulence = reduced cavitation. – Serguei Dec 6 '17 at 7:52
