Water is leaking from a cap

Hello everyone I need advice on what to do with a problem around my water heater I don't know if threaded cap needs replacing where the leak is. It is on a water pipe that goes to the water heater. To be honest I don't know if it is a threaded cap or a something else.

Please look at the picture to get a better understanding of my issue. The leak seems to be growing and I am worried that it may get worse if I don't do anything about it.

*Thank you, please remove if this is not allowed here and point me in the proper direction*

That's a drain hole. There is little rubber piece that is under the cap. When tightened it wont leak. It must be damaged or not even in there.
Those are used in valve to drain a line down stream. The valve should have an arrow pointing in the direction of flow. If it's in the opposite direction it was put in backwards and servers no purpose.

Agree - if tightening wont do it its easier to replace it than finding a washer. https://www.lowes.com/pd/AMERICAN-VA...E&gclsrc=aw.ds
