A kitchen island is a nice thing to have in any kitchen. It provides versatility and functionality to your kitchen. However, the plumbing associated with an island sink is far difficult to install than a regular sink against the kitchen wall. Everything needs to be contained on the island itself which is the primary challenge. These tasks are typically reserved for the pros. Of course, you can always do it on your own but requires some plumbing know-how, tools, and experience.
Here are the steps on how you can install a kitchen island sink
Choosing between an AAV (Air Admittance Valve) or an island vent
Unlike plumbing a regular kitchen sink, an island sink is more challenging. It requires a different approach. There are two ways to plumb an island sink. The first one is to use an air admittance valve and the other is to install an island vent. Here’s a breakdown of both options:
An island vent ensures equal pressure in the Florence plumbing system. When wastewater drains too slowly, debris could clog up the pipes. If the opposite happens, water is sucked from the P-trap which lets in harmful sewer gas in your pipes, out your sink drain, and into your home.
Air admittance valve
Unlike an island vent, an AAV does not require outside venting. It uses gravity to open the valves when water flor creates a negative pressure which allows air to equalize the pressure. However, there is a significant drawback to this system. An AAV can be overworked and might not keep up with high water discharge. Consider using an island vent if you are planning on attaching a dishwasher to your island sink. Ask your plumber for more information on what’s best for your setup.
Plan where your pipes go
Adding an island kitchen sink will involve taking apart sections of the floor to lay the piping. Before you proceed with removing your flooring, plan the layout of the pipes. Pick the shortest distance from your kitchen’s main waste stack to your kitchen island. With the complexities involved, it is advised to hire experts like Plumbing Experts Florence for the installation of the piping. Although you may do it on your own, there’s no real guarantee of good results.
Prepare for drain installation
To install the drain of your sink, you must first insert the drain and the tailpiece that comes along with it.
- The P-trap will attach to the tailpiece.
- Afterward, the PVC extension will connect to the end of the P-trap.
- You will then need to move the P-trap around and align the pipes and mark the intersection.
- Using a hacksaw, cut the drainpipe to where it intersects with the extension pipe and remove burrs with sandpaper.
- Position the sanitary tee so it points towards the P-trap.
- Connect the extension pipe with the sanitary tee.
Installing plumbing to your kitchen island is like a huge jigsaw puzzle. However, if you don’t have the tools and experience to put it all together, you may end up with a huge mess. If you don’t care to gamble and prefer to spend your time on other things, call a plumbing contractor to do the installation for you.
