Leaky tap

Noticed the tap is leaking, traced to the underside of the kitchen sink and it appears that the leak comes from the connector. I tried to tighten it with a wrench but there's not enough clearance. I was wondering is there a special tool for situations like this? Or does it require the removal of the entire faucet?

Thanks in advance for your responses.

They generally don't come lose as they aren't suppose to be over tightened.

The o ring keeps it watertight.

I'd take off the mixer and see how tight or loose it is. Don't over tighten it.

It could be a number of things.

How old and what brand is it?

Thought it was a 2 minute fix, now sounds like a project for the weekend.

Meanwhile I have put a bowl underneath to catch the leak.

Not sure about the brand, some no name cheapy, it's not even that old. Will take a closer look on Saturday, may be time to upgrade to something better.

I'm not a fan of cheap tapware, they aren't very cost effective.

You can get a quality kitchen mixer from $100.

Not to hard, really. Undo the mixer, lift it up and check the connections. When checked replace. Worst case is it still has a slight leak in which case get new "o" and fit them. No need to hit panic stations just yet.

Usually a small open-ended spanner will fit.

It can be done from within the cupboard by undoing the lower end, and tightening the top connection. If it still leaks the inner O ring needs replacing

^^^ X2 !

worst case scenario me thinks to change the braided hoses.
