[glen brown via Personal_Submersibles]

Alec
I have two running my  R O system,one on the surface  its been pumping 15
bar 24/7 for the past two years ,the other one providing the same water
 system from 80 meters below the surface controlled by a float switch this
one has been pumping for three years no problem whatsoever.I had a 75 pound
trolling motor in one of my 16000 litre nutrient tanks to mix nutrients in
my hydroponic water I ran it 24/7 for a full year then it just stopped not
bad neither.
