Do you want a large kitchen island that is trending nowadays? Plumbing a kitchen island is a good idea because it gives your kitchen an adorable look. As well as you will get extra space to manage your kitchen utensils and groceries.
It provides more space to serve your guests and family friends during a party or family function. However, you need to be very careful when designing your kitchen sink or dishwasher. This blog will tell you about installing a kitchen island by yourself. Let’s start!
The Challenge About Plumbing a Kitchen Island Sink
Firstly, look carefully at your kitchen’s topology, then design your island according to it. If you are new to plumbing and doing it yourself, be aware of your kitchen sink location. It should not be adjacent to any side wall or supporting pillar.
The water, drain, and vent requirements are the same for a small kitchen island as for a common sink, but the plumbing should be underground. So, if you are going to redesign your already renovated kitchen, it becomes messy. However, if your home is under construction with an open floor, you can do it quickly.
Apart from sink fixation and underground plumbing, it would help if you consider properly removing sewage gasses from your kitchen island. Therefore, drain pipe manufacturers recommend an island vent or air admittance valve for this purpose. The choice is yours, what suits you best. Stay with us to get details of both options.
Waterlines, Drains, and Vents Fixation
Waterline installation is simple and does not require any expert opinion. You can adjust pipelines as convenient for you. But don’t forget to take some extra length of hot and cold water lines for uninterrupted connection with faucets.
Here, the crucial plumbing stage starts when you need a second thought for help and assistance. You can call Plumberstar for a second opinion. You have to change the vent and drain system for plumbing on a kitchen island.
Usually, kitchen sink traps hold a small amount of water that contains little gas and empties all with other flush-out water. Doing so is helpful to prevent your kitchen island from suffocation. A single P-trap can fulfill this job. But in the case of a kitchen island, you need another one to leak backwater towards the floor.
You will get an S-trap configuration, and it’s not suitable for a kitchen island with seating. Drain manufacturers and suppliers design a special sink loop vent to overcome this trouble. Loop venting is the most common method of preventing water locks and supports effective ventilation.
Island Vent
Plumbing kitchen island vents consist of pipes that connect to make your place gas-free. Their working mechanism depends upon maintaining constant pressure inside your plumbing system. Continuous and high pressure support the waste and water disposal from the kitchen drains.
Thus, island vents are suitable for plumbing a kitchen island. Scroll down to learn how to vent plumbing on a kitchen island. It is not as difficult as most plumbers and pipe fitting manufacturers suggest. All you have to do is adjust the water flow downward toward the floor.
Select an inverted U pattern vent pipe and adjust it with a fitted p trap. The top of the vent pipe should run upward to the counter’s bottom and loop back downward. The lower bottom should pass through the floor to the main drain. Replacing kitchen countertops can make your job easier.
Once you complete all repairs, connect the main drain with hot and cold water supply lines. Don’t forget to connect this vent pipe with your home’s central vent. You can choose the sink vent design according to your available space and the distance between the main drain and the loop vent.
Are you unable to connect your kitchen sink vent to the central vent? Kitchen drain manufacturers ask to install an air admittance valve in such a situation. Look at installing an air admittance valve in plumbing your kitchen island.
Air Admittance Valve (AAV)
Are you in a hurry and don’t want to make many changes? An air admittance valve (AAV) is the best solution that requires no external venting. You do not have to mess with replacing the kitchen countertops. And it requires significantly less time to install. So, if you can’t wait any longer and need a quick renovation, opt for an air admittance valve.
Although their working mechanism is quite different, they use the earth’s gravity to allow water flow to pass through them and generate negative pressure inside. As a result, air enters inside the valve and equalizes pressure inside the unit. Hence, plumbing a dishwasher in the kitchen island with AAV is a great idea.
But we would like to tell you the valve manufacturers’ opinions about this product too. Important note: Before purchasing, ask your local plumbing inspector if it is allowed to fix in your area. If he approves the product, then you are good to go.
Also, think twice if you are a small family with few guests to accommodate; then AAVs work best for you. You can also choose a plumbing kitchen island with seating. Valve manufacturing brands focus on properly installing valves for appropriate functioning of gas removal. On the flip side, if you have a large family with a high volume of water usage, then AAVs are unsuitable for your venting requirement.
AAVs stop working if the discharge rate from your vent is more than 18 to 22 gallons per minute. Furthermore, it will not support the venting pressure of a high plaza or building with more than five floors.
