New homeowner here. I was poking around in my garage yesterday and noticed what I THINK is my water filter and how filthy it is (I’m on a well). I was googling around a bit for advice on how to replace it, but wasn’t coming up with much. Here’s a photo:
Also, while googling everything I DID find mentioned 10″ or 20″ being standard and I’d say this one is more like 6″ and looks much smaller. We have 2.5 bathrooms, should I think about upgrading to a larger one?
