6 Easy to follow Steps to plumb a 3 Compartment Sink
There is a complete guide to plumb a 3 bay sink. You can follow these steps by doing it yourself.

Once you have laid the pipe into the cabinet housing the 3 compartment sink, you now need to increase the pipe up to about 5-inches under the sink.
Step 2: Check 3 Compartment Sink’s Kit all Pieces
Secondly, we have to check our sink plumbing inventory. If we observe any installed three-compartment sink, we notice that it has an elbow, drain tailpiece, and center tee under the sink.

Step 3: Pipe Marking
Now, insert the drain along with its tailpiece. Attach the P-trap assembly with the drain tailpiece. Next, you have to connect the PVC extension pipe to the end path of the P-trap.
Move the P-trap along with the PVC extension until it touches the drain pipe. After this, mark the pipes in places where they are to be cut. Cut the drainpipe, following the marks. Use a hack saw for this purpose. Make sure to remove any burrs with the help of sandpaper.
Step 4: PVC Pipe Cutting
Cut the PVC pipes in the marked areas. Use sandpaper to smooth the ends of the PVC pipe. The pipe will be burr-free. Try to focus that the cut piece of PVC pipes will joint the exact places you had marked. It’s time to identify the drain of your wall. Center-set drains can be installed directly with a P-trap kit, thus requiring no additional pieces.
Moreover, in the offset drains scenario, first install a P-trap kit, extend a flexible hose outside the wall, and drain the water. The drain of this type should be flexible enough to curve around to fit with wall outlets.

Now it’s time to install a sanitary tee and PVC p-trap. With the sweep facing up, you should position the tee such that its outlet points to the p-trap. Never forget that the outlet pipe and the extension pipe will be of the same size. PVC cement is required to attach the tee and the drain pipe. Please tightly connect the tee and extension pipe connection.
On the centre-set tail, align the p-trap kit with the wall so that the bottom of the tail becomes a p-trap. You can use the tail extension piece to the sink drain’s bottom if necessary.
Step 6: Leakage Check
Finally, the 3 bay sink has been plumb, and now it’s time to check the leakages. If there is any leakage in the joint, you will tighten the connections.
