I have a Watts Premier Ro Pure water filter, after use water start to leak under base of faucet. I checked for leeks around the spout which have 2 O rings and it’ fine. What can be the cause of the leak?

Hi Demovey

If it isn't leaking up under the sink connections and it isn't leaking from the spout o-rings then there isn't much else left, but a failed unit!

In my experience it is almost ALWAYS the o-rings, but if you say that isn't the issue I would go down to a local plumbing supply house and purchase a new dispenser... universal stuff there and pretty cheap overall! It is usually a real quick install, so don't waste too much time messing with this, OK?

Good luck!
