Leaking Magnaclean magnetic system filter

This was the 2nd of my 6 jobs that I did on this Friday for a customer who lives in Barnsley, S72. This repair wasn’t anything major, actually quite a trivial problem.

These type of filters have an O ring seal at the top which can leak. On the lid it does stipulate that the lid should only be hand tightened, but often they get over tightened. There is a tool to remove the lid sometimes it is used to tighten the lid as well.
