How Your Different Bathroom Sink Drain Parts Work

Many different parts make up a sink drain and they all must work together for the sink to properly function. Knowing how each part works and interacts with one another will allow you to troubleshoot problems with your drain more efficiently.

A standard bathroom sink has two drains one for water from the faucet, and one for draining water after washing hands or doing other tasks where water doesn’t remain in the basin. This second drain is called an overflow pipe because it allows excess water to leave the basin through this opening when too much enters. The stopper is lifted by pushing down on it with your hand however, this causes a chain reaction of events that lead to the plunger moving up and down over the drain opening.

Lower The Drain Outlet If Necessary

If you find that the existing drain outlet is not low enough to accommodate the depth of the new sink, you will need to open the wall and lower the position of the sanitary tee connecting to the drain pipe in the wall. This can be a somewhat complicated job that requires cutting away the back of the cabinet and the wall surface.

Our example is a case in pointthe new sink left insufficient room for connecting a standard drain assembly to the drain outlet in the wall . So, the sanitary tee fitting serving as the drain outlet has been lowered . Keep in mind that the drain height must leave enough room for removing the trap and cleaning it out.

If you need to lower the sanitary tee in the branch drain, it is a good idea to wait until the other parts of the drain are test-fitted before gluing and securing the fittings permanently. Leaving the fittings loose will allow you some room for adjustment.

Before continuing to the next steps, remove the old sink and install the new sink in the countertop. Our installation will include a double-basin sink with a garbage disposal fitted to the right basin.

Not Using Enough Plumbers Putty Or Sealant When Putting In Your Drain

How to Connect a Bathroom Sink Drain

Not using enough plumbers putty or sealant is very easy to do, but it can lead to some big problems down the road if you don’t use enough of either on your new hardware. To combat this issue, make sure you go back over all of the delicate areas after finishing with everything else below the sink and add more sealant. Doing so will prevent leaks from ever happening around any of your connection points between your plumbing lines and your new drain assembly.

Prepare The New Drain Assembly

This is the first step when it comes to installing the shiny and new sink drain. Start by disassembling the drain and removing the mounting nut, washer and gasket from the drain stem.

If your new drain assembly comes with a gasket for the topside of the drain that seals it to the sink, slip it up against the drain cup. If you dont have a gasket, apply a small bead of siliconecaulk or plumbers putty to this flange instead.

How To Connect A P

First, slide the p-traps short side into the tailpiece that drops down to the sink drain. Align to the opening on the wall the trap arm by moving it up or down.

If the trap arm is below the wall drain fitting, and you cannot move the p-trap higher up the tailpiece, use a hacksaw to cut the tailpiece. If when attached to the end of the tailpiece the p-trap lies above the wall drain, then purchase a longer tailpiece.

The trap should be installed directly under the drain so that one can verify whether or not it is holding water or has been damaged.

Water gravity that forces water out is also greater when the trap is directly under the drain.

The trap arm connecting the vent pipe horizontally from the p-trap must have ¼ inch per foot slope sloping up towards the drain.

Take apart the lower part of the p-trap and then insert the trap arm into the wall drain fitting as far as it will go.

Start pulling out the trap arm from the wall fitting to the point where it will exactly fit with the top U-shaped portion of the trap.

You will need to purchase another p-trap if the trap arm comes out completely from the wall before getting attached to the trap.

You will need to cut the trap arm if it is in the wall fitting and still extends past the u-shaped part of the trap. Use a hacksaw to cut it to the appropriate length.

Insert back the trap arm into the wall drain. Align the trap arm back to the trap and thread on the slip nut without tightening it.

While you can cut the wall open on your own, it is a reasonably complicated job, so its best to seek the help of a professional. If youre doing it on your own, you should leave sufficient space to allow for removing and cleaning the trap.
