thanks. I'll go and change the cartridges and see if that works.
However, why would the water still cut off if I cut off the water
supply to the filter?

I'm not sure what you mean by cutting the water supply to the filter and
still having water cut off. If you close the supply to the filter, you
should be getting no flow? Does your filter housing have a top section that
turns to shut the water off? Could be the problem there.
