Low reading on Barnstead E-pure D4641


Date : 10/14/2019
From : Andy

Question

Hi I have a thermo scientific Epure 4 module water filtration system model D4641 7119 The resistivity meter was reading 182 on a saturday morning while it was being used The filter system was left on over the weekend and monday morning the resistivity meter was reading 24 My question is how do I troubleshoot this problem Is is the meter or the cartridges Will cartridges go from 182 to 24 that quickly Thank you


Answer

Turn the system on and draw off water and see if the resistivity goes up. If it climbs way up when drawing water, but is low when not drawing water, usually means you have a bad pump. If it stays low or goes lower when drawing off water, the filters need to be changed. It is normal for the system to crash quickly when it does.

This is the filter kit for your system./
