Steps On How To Plumb A 3-Compartment Sink

Design The Path Of The Pipe

Design the path of your pipe by laying out a graph showing where you want to go. If you don’t have any experience with plumbing, it may be helpful to sketch one up before buying fixtures and materials for installation.

When designing the route on paper, make sure that all three compartments are easily accessible without having to move around obstacles or bend over too much.

Plan the route and make sure that it is a straight line to avoid bending or contorting your body when accessing each compartment of your sink. When laying out this path, also take into account where you want to install your faucet – should be near enough for easy access without making anyone have to move around any obstacles or bend too much.

Plan the thickness of your pipe so it can provide adequate support for whatever you need to do with your sink, but also make sure that there is enough room left over to allow for easy access around fixtures and big objects such as garbage disposals.

Taking into account these factors will help to prevent any potential problems later on. Measure the distance from where you want to place your faucet, to where each compartment is located.

Once this measurement has been taken for all three compartments, take a look at what pipe fittings will be needed and then go about getting those items in order to continue with the installation.

Choose the best size of hose clamp that you need for each component, based on the diameter of your pipe.

Split Up All Pieces

Once you have all plans ready for the path of the pipe from the water supply to each compartment, you’ll need to split up all pieces. These will include:

  • center tee
  • elbow
  • drain tailpiece sections
  • drain tailpiece
  • vent fittings
  • barb and hose clamp

Highlight All The Cuts

Once you have all the pieces laid out, use a marker to highlight where each piece will be cut. This will allow you to see where the pipe will be cut and how it is going to fit, before making any marks on your actual material.

Highlight all of these areas with a marker so that when you go about making cuts in each piece, there are no mistakes or errors made which could create problems for future installers.

Take care of all the cuts for your sink. Make sure you are taking care of cutting out all pieces before moving on to installation, otherwise it could create problems later in the process.

Cut Up Your PVC Items

After you have marked/highlighted all the cuts for your sink, you will want to go about cutting up all the PVC pieces. Use a hacksaw blade for these cuts and make sure that they are not too rough or jagged in order to avoid creating any potential problems during installation.

Installing a 3 compartment sink doesn’t need an additional piece for the center set-drain as it attaches to the p-trap kit. To install an offset drain, first, you’ll need a P-Trap Kit. Once installed, you can also use a flexible extension to allow the water to go outside of your wall.

Keep an eye on where you’re cutting so there is no need to follow up with sanding later on. This will make for a cleaner and smoother installation that won’t have any issues with sticks or gaps in the piping system.

Insert The Sanitary Tee & PVC P-Trap

You’ll need to insert the Sanitary Tee and PVC P-Trap first. This will create an outlet for any liquids that may flow from your sink, which can then be drained outside of your house or into a bucket.

The sanitary tee is placed in between two pieces of pipe with the top fitting being threaded on one side and the bottom fitting being threaded on the other side. This will allow liquids to flow out of your sink and into the drain, without any restrictions or issues.

A PVC P-Trap is a very simple piece that can be installed in just about five minutes time. First, you’ll need one of each connector (female/male) for this part and then you will thread the male connector to the PVC P-Trap and a female connector to your sink.

This is an easier configuration for installation, but it may not be as durable or long-lasting in terms of design, so keep that in mind before deciding on this method.

At Last Check For The Leaks

After you have everything installed, make sure to test the system for any leaks before finalizing your work. You’ll want to go about this step by checking all fittings and connections that were previously made in order to ensure a good seal was formed without anything getting loose or disconnected. This is very important because if there are any leaks anywhere along the way, it can create problems or even damage to your home.

Make sure you are checking for leaks as a final step before finishing up the installation process on your three compartment sink! This will save yourself from having any issues later on down the line with this design choice and make for an easier install overall.
