Question
Do Lachat pump cartridges go bad?
Summary
Pump cartridge wear
Answer
The Lachat Pump Cartridge - PVDF (Product # 22043L) can get worn over time. The arrows point to the part of concern.  There is a wall on either side of where the pump tube lies when the cartridge is clamped into the pump.  As the wall is worn down, from where the cartridge contacts the pump rollers, it can affect the tension on the pump tube.  Cartridges typically last several years but are a consideration if there are flow issues and the cartridges have had a lot of use.
