Save Bucks By Learning How To Install A Pedestal Sink

You would agree with the fact that our house only becomes a home when all the different components of it begin to work in synergy. Our home is an agglomeration of a large number of things that we require in our daily life.

One such important facility all houses should have is a pedestal sink. I am pretty sure everyone here knows about the need for a pedestal sink. We require a sink to get ready in the morning and wash.

Have you ever thought about how to install a pedestal sink? Here I am gonna show you how to install a pedestal sink without having to pay a single dime to your plumber.


What you might need

As this is a laborious job, you will need some tools and items before you can begin. Before you start, it is important to remember to shut off your main water valve. You also need to have all the measurements marked out before you can install your pedestal sink. Other things that you might need include:

  • water pump pliers
  • hack saw
  • pvc saw
  • screwdriver
  • wrench
  • drill
  • trap
  • faucet
  • nail and other essential items

Trap is the curvy pipe under your sink, which helps by retaining enough water so that harmful gases cannot enter the washroom.

And finally, the pedestal sink that you wish to install

What You Should Do


Do The Rough Plumbing

Before we can install the sink, it is important to do some plumbing work on the pipes. Get hold of a tubing cutter in order to cut both the copper supply lines. Cut them at a distance of a couple of inches from the wall. Also, measure the distance between the basin’s drains and the wall and mark it.

Hold the P-trap along with the elbow alongside your pipe in such a way that the trap's vertical end is centered on the mark. Mark the point in the PVC where the elbow will be attached and cut away the excess pipe using a hacksaw. All these steps would make a suitable place for attaching your sink.


Soldering The Supply Lines


Ream the sides of the supply lines that you cut with your tubing cutter to remove burrs left in them. Also, polish the copper with sandpaper and coat it with flux. Solder the end of the copper supply lines and remove any exposed flux.


Installing The Pop-up Drain

Now comes the important part. Roll a bit of plumber’s putty and into a small thread and place it underneath the pop-up drain. Use a rag to wipe the basin drain hole dry and clean. Drop your pop up drain into the basin drain hole.

Underneath the basin, fix the gasket and a washer into the drain pipes. It is important that you thread the nuts and tighten them properly with the help of a water pump pliers or wrench.


Leveling Your Basin

Now that your drain has been fixed, it is the time to level your basin. Place your pedestal in such a way that it aligns with your PVC waste pipe. Make sure that its center and the drain basin’s center are at an equal distance away from the wall.

Place your basin on your pedestal against the wall. Do fine adjustment on the pedestal and the basin and leave them side by side. Using the mounting holes, mark the places where the screws have to be fixed. This will come in handy later as you will need to drill holes there.


Attaching The Trap

Move the sink and pedestal together from the wall. You may need the help of another person to move the structure without dropping it. Fit your elbow and P-trap assembly with the PVC waste pipe as a trial. Next, just measure the distance between the floor and the trap’s top end. Also, measure the distance between the floor and tailpiece of the waste assembly.

Take out the elbow and put the P-trap's washer and slip nut over the tailpiece of the waste pop up. Using a plumber’s tape, cover the threads in the P-trap and slide the trap till it reaches the mark that you made earlier.

It is highly recommended to cover the nut with thread by hand before tightening the nuts with a wrench. However, be careful that you don’t scratch the chrome polish. Drill the holes for attaching the basin to the wall.


Mounting The Faucet

Using O-rings or plumber’s putty, insert the faucet’s valves and spouts into their designated holes on the sink’s deck. Now, place thread and gasket on the lower side of every fitting. Turn all the nuts by hand and tighten them using a wrench before carefully moving the entire setup back onto your wall.

Place the mounting holes of the basin. Fix the structure using lag screws, while keeping their fender washers on the mounting hole in the sink. Check the level and tighten the screws with a wrench.


The Final Touch

Now that you have almost installed the sink, it is time to make some final connections. This includes placing a washer between the trap and the elbow of your pipe, doping the threads in the nuts, and tightening all the nuts manually. Make sure it is completely tightened with the help of your water-pump pliers.

Tighten The Pipe With The Help Of Your Water-Pump Pliers

Find the distance between the faucet valve and one of the angle stops and add one inch to it. Cut your supply tube to the required length with your tubing cutter. Insert a ferrule and a couple of compression nuts over the sheared end of the pipe. Tighten the first nut using a wrench. Bend the supply pipe a bit to its side and back up till its head fits the basin’s water output.

Next, screw the head tightly with the help of a second nut. Similarly, do the same for the next angle stop and the faucet. Keeping the lift rod in an upwards position, attach your pop-up stopper with the actuator arm.

Tighten the actuator arm to the lift rod using the screws provided. Place the cover on top of the waste pipe and insert the escutcheon as your finishing touch.


Making Sure Your Sink Works

Open Your Tap And Check For Any Leaks.

After you have finished installing the sink, it is time for you to check whether it is working. Remove the spout’s aerator and filter and open your tap. Allow for any debris to clear and repeat the same for the other faucet. Check for any leaks in the faucets or the internal plumbing of the sink.
