PTFE frit in Quat Pump always dirty

Hello! I have slightly increased the amount of use my HPLC gets but I am having to change the PTFE frit in the Quat pump what seems like a lot more often. Probably once to twice a month. Is there anything else that anyone thinks that could be causing it to get dirty? Or is it more likely to just be from just the increased usage? We do not have a normal maintenance routine as we are a very small company. I am working on developing one.  Thank you for any help you can provide!

 

ETA: I am having pressure issues when this happens and causes it to stop working. I forgot to mention this.
