The clevis connects to a pivot rod-and-ball assembly that consists of a rod that runs through a rubber pivot ball and slopes slightly uphill to the tailpiece of the stopper.

How to Drain and Vent a Bathroom Sink

Pushing the knob and the lift rod down causes the pivot rod to push the stopper up; pulling the knob up causes the pivot rod to pull the stopper down. If you want to remove the assembly, you may be able to pull it right out. Or, you may have to twist it to unhook it from the clevis. This flange is screwed into the drain body, which is tightened to the underside of the sink bowl with a locknut.

The tailpiece, which may be fitted to a pop-up stopper, attaches to a drain trap by means of slip-joint couplings. The faucet supply hoses connect to the shutoff valves and faucet inlets, and you tighten them with adjustable pliers. They must have the right size connectors to fit, so it's worth checking before you buy the hoses. After connecting the pop-up stopper, the sink should be ready to use.

Skip to main content. Overview The supply, drain and vent pipes for the sink tie into the system of pipes already servicing your bathroom, and the difficulty of the rough-in depends on the system's overall configuration.

Installing the Pipes The locations of the supply and drain stub-outs are important. Preparing the Stub-Outs Before you hook up the sink, you need to install shutoff valves on the supply stub-outs. Connecting the Sink It's always easier to preinstall the faucet and drain onto a sink before installing the sink so you don't have to do these procedures while lying on your back. The specific size of the connectors should be included in the instructions for the specific faucet that you're installing.

You want to get lines that will have the appropriate ends for valve end and faucet end. Better to have extra long lines and have them loop.

No hard bends or kinks. Make them hand tight, and somewhere around a quarter to half turn with a wrench. The pop-up is the device that allows you to open and close the sink drain, usually made of a simple metal rod with ball attached to it.

Slide nut to trap the ball in the tailpiece. Attach thumbscrew to pop-up lever rod while sliding the rod from the ball so they can attach and allow you to screw together. Seal your connections with silicone caulk. Finish with silicon around the top of the sink, anywhere that the basin of the sink meets the wall, filling any gaps with a thin bead of caulk. Let the caulk dry for about 24 hours before turning on the water and going back over your work to check for leaks.

Turn on the water and check for leaks. If you have small leaks from the rubber connections, try tightening more. The drain itself will also sometimes leak, which can be caused by over-tightening and straining the seal created by the connector gaskets. Try a new washer instead. It's also a good idea to check the gasket that goes under the tailpiece.

Try tightening the nut down more or try different washer or silicone.

Typically, you pull the collar on the hose end away from the end and release it once the nozzle's snap adapter is fully seated into the hose end. It may not have been installed correctly, and if someone just shoved the nozzle into the snap connector, then that's likely why it came off to begin with.
