Presumably you are mentioning a kitchen or bathroom sink drain?
Underneath most sinks there is a "P" trap leading to the drain line which goes out to the outside sewer system. Occasionally the drain line is simply loose and needs tightening by hand or lightly with a wrench. (do not over tighten) If not, loosen the fitting(s), removing the drain line and replacing the seals is in order. These seals can be purchased at most hardware stores. Be sure to have a small bucket handy to catch water residue in the "P" trap once removed and, be sure to clean and wipe all ends of the pipe prior to reassembly so the seals will work properly.

The same way you would fix any other drains within the house. Pour some Baking Soda in the drain, let sit 5 minutes or so & run hot soapy water down that drain for at least a minute..

If the sink is leaking from an area that is not the drain, you likely have a cracked sink that is now useless.

Assemble the hardest part first, but don't tighten it up. Connect the other parts, but don't tighten. Go back to your hardest piece and tighten. Then tighten the remainder.

Standard Vanity height is approx 34.5". A vessel vanity is approx 31" high. If you cannot remove the legs from your existing vanity then it will have to be replaced or cut down to the correct height. The reason a vessel vanity is lower is because your sink will be approx 3 to 6 inches higher than a standard drop in sink. This may be more work than it is worth. Vessel sinks most often will require a solid surface top, either glass, stone or another type of composite material. The standard laminate vanity top has a particle board substrate which will detiorate quickly at the drain location.

there is a small compression nut on the drain, it needs to be tightened slightly. look under the sink when you pull the lever up close the stopper, you will see where it connects to the drain. tighten that nut slightly.
do not over tighten or you won't be able to move the stopper at all, you just need enough pressure to hold the weight of the lifting rod and stopper in place.

Pegasus make several models but I'll make an assumption that it has a pop-up plug actuated by a rod just behind the tap head.

If correct....

Under the sink in the cabinet you will see the rod comes down and connects to an adjustment fitting and into the main drain line from the sink. There will be a fitting on the drain line holding the connection. Inside is a metal ball and connecting rod that links to your plug.

Remove the fitting.
Slide the ball and rod partially out.
Put your plug back in.
Engage the rod again (you will need to fiddle a bit here).
Tighten the fitting.
Run water to ensure the fitting is tight and not leaking.


Should be good to go.

Please rate this answer if it gives you some direction.

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

You can get an acrylic sealant to put around the drain. It will fill the void where the flange on the drain hole and the sink meet. Possibly an epoxy would work but some tend to yellow with age.
