My bathroom faucet leaks a drop of water every 30 seconds

Usually, there is a filter-like mesh at the mouth of the faucet for producing the air bubbles. You may try to turn the mouth part using a suitable plier to see if it can be taken out and you may do something about the mesh.

tape it!

If this was a totally new installation, there is debris from the water lines. If you disassemble the unit, just crack the 2 supply lines just enough to get water flowing with valves removed, it should clear the debris in a few seconds. You may want to close the sink drain in the event any small parts dislodge. If it is a chunk of teflon tape, or small streamer it can get caught inside the stem.

Then just inspect each stem closely for damage or debris that has hooked a seal and remove it or repair it as needed and reinstall.

They are factory tested so any leaks are the result of debrs from your plumbing lines. It is a common occurance. It is not always possible to "police" every bit of plastic or copper that may be created in the process of a faucet installation.

Look carefully at the seal for the airator. this sprays water up inside the faucet and leaks as you describe.

No warrantee on new home?

No instructions left for ALL fixtures,water heater,heating system etc that where installed???

Go to a plumbing supply store,and see if they can help. Not Home Depot

check the strainer where the water comes out of your faucet it may be clogged or if the faucet has a cartridge in it it may be clogged and you will have to dis assemble the faucet to clean it usually the strainer is the problem and it should unscrew by hand

Take the strainer off the spout and check to see if there is any dirt or rust buildup in the strainer. This happens when repairs have been done. It usually collects at the first place the water comes out of.

check under sink for a clogged or a bad trap in drain. it is hard to believe that the smell is coming from faucet.

where are they leaking from?
if they're leaking from underneath, repace the suply lines [between the valve and faucet]. if if from the faucet itself replace your cartrage[s].

There is a small allen screw in the base of the handle- the part the stem screws into to turn the water to the on position.
