Quieter pump desired for Aeroflo-18
I have a newly installed Aeroflo-18. The pump has enormous pressure but has a loud hum you can hear throughout the house. The pump is very good quality but I'm looking for something quieter. Since GH uses this same pump on the Aeroflo-30 it seems I could get satisfactory results with a much smaller pump.
Does anyone have any experience doing this? It needs a 1" NPT fitting - anything smaller would be too restrictive. Any experience with Elemental Pumps like EHP252
The Quiet One pumps have been recommended here but have terrible and consistent failure reviews on Amazon.
