It's leaking right where the arrow is pointing. It only leaks when it's refilling the tank after each use. The two outside carbon filters were new in March but the middle (reverse osmosis) filter is probably a year or more older. I'm hoping it just needs a new RO filter and that it's only leaking because it's clogged. Any advice? I feel like that notch it's leaking from is meant to relieve the pressure when clogged.
I'm just getting ready to head to work but I'll remove that part and take pictures when I get home this afternoon. Thank you for your suggestion!
