Why Plumb a Double Kitchen Sink?

When you are doing a total kitchen makeover, most people want their kitchen to be up-to-date with all of the current trends and styles. One of the most important things that have come into style these days is having double sinks in your kitchen. Having two instead of one not only looks great, but it is also more practical and efficient. Double sinks make it easier to wash dishes because you can have one side designated for washing and the other for rinsing, which makes clean-up time much faster overall. In addition, having two faucets instead of just one means that you don’t have to stand as far back from the Sink to get your hands wet. As everyone knows, having to stand too far back can be quite uncomfortable when trying to do dishes or wash the occasional frying pan.

Types of Double Kitchen Sinks

There are actually three different types of double kitchen sinks that you can use in your home rather than just one. The three different types available include a split faucet double sink, a single faucet double sink, and a triple faucet double sink.

Types of Double Kitchen Sinks

A split faucet double sink is the least expensive of all the three types that you can choose for your kitchen. This type of double kitchen sink will come with two separate filtration systems and one main water pipe. The single faucet double kitchen sink is a bit more expensive than the split faucet double sink, but it will come with two separate water filters, two hot water faucets, and one cold water faucet. The last type of double kitchen sink is the triple faucet double kitchen sink. This type of double kitchen sink will also come with two filtration systems, but it has three different water sources instead of just two like the other double kitchen sinks.

What to Look for When Purchasing a Double Kitchen Sink

There are certain things that you should look for before you purchase your perfectly new double kitchen sink. The first thing that you should consider is the size of your counter area where the double kitchen sink will sit. You then need to determine what type of Sink you want for your kitchen. Your final consideration should be the type of faucets that will come with the Sink.

How to Install a Double Kitchen Sink With Disposal And Dishwasher

First, you will need to install the new dishwasher and then cut holes in your countertops for the dishwasher and disposal. This blog will suggest to you how to plumb a double kitchen sink with disposal and dishwasher.

Modify Your Sink Cabinet:  If you are starting with a single kitchen sink cabinet, you can use it as is or modify it so that it has room for two sinks. To do this, create a center divider that separates the two new openings for the dishwasher and disposal.

Single Kitchen Sink Cabinet

Measure Twice, Cut Once:  It is very important to measure either your existing cabinet or your appliances before you go out to buy your new Sink. After getting the correct measurements, cut holes in each side of both cabinets using a hole saw bit for the dishwasher and disposal openings.

Attach Drawer Fronts:  Attach the dishwasher drawer fronts to the face frame of each cabinet. Use the existing holes in the drawer front for any screws or nails you need to attach to your cabinet. Once the front is secure, slide your dishwasher into position before attaching anything else.

Attach the Sink to the Cabinet:  Slide your new double Sink into position under the hole. Mark, where you would like your faucet, and drill holes using a hole saw bit for each of the two faucets. Attach Sink to cabinets using either screws or nails depending on what type of material you are attaching it saw bit. Drill a small pilot hole first, and then use the larger hole saw bit to make your holes for your faucet.

Attach Brackets Underneath Sink:  Place the dishwasher brackets underneath the Sink before attaching them to the underside of the cabinet. Make sure to attach these brackets with screws that are going through a piece of wood and then into the bracket.

Attach Back to Cabinet:  This step is only necessary if you modify your single cabinet into a double kitchen sink cabinet. If not, you can skip this step. Measure and cut plywood pieces to go around the dishwasher and disposal so that there is a 1 inch overhang on each side of the cabinet. Once the plywood is cut, attach it to your cabinets using nails or screws using a nail gun.

Attach Drawer Fronts:  Slide dishwasher drawer fronts onto the face frame of each cabinet. Use existing holes in the drawer front for any screws or nails you need to attach to your cabinet. After attaching the drawer fronts, slide the dishwasher back into position before attaching anything else.

Instead, use screws to attach brackets underneath both sinks to support them. Attach backsplash to the cabinet using either screws or nails, depending on what type of material you are using.

Attach Wall Cabinets to the Floor:  This step is only necessary if you are replacing your existing Sink with the new double Sink. If not, you can skip this step. Instead, place wall cabinets onto the plywood that is already attached to your cabinets. Use screws or nails depending on what type of material you are attaching it saw bit.

Add Hardware:  Finish off the look of your new kitchen sink with hardware such as double knobs for your drawers or towel holders to go under each Sink. Make sure you use a level when installing hardware to have an even look throughout your new kitchen.

Frequently Asked Question

Can 2 Sinks Share the Same Drain?

In most cases, 2 sinks can share the same drain. However, it is always recommended to have a separate drain for each sink. There are two types of drains:

  1. Separate Drains – These drains will not connect, and you need to install a new one if you want to run both sinks simultaneously.
  2. Common Drains – These drains will connect, and they are connected via an adapter piece which allows both drains to work simultaneously.

Does a Double Sink Need a Vent?

A double sink does not need a vent. The installation of a double sink is typically done with the help of a plumber and an experienced contractor who will ensure that the process goes smoothly.

How Far Should Vent Be From P Trap?

To find the correct distance, you should first measure the length of your vent pipe. Next, you need to divide that number by two to get the distance from the trap.

For example, the vent pipe is 8 feet long and 2-inch in diameter. So, divide 8 by 2 (4) and then divide 4 by 2 (2). That would give us a distance of 3 feet from trap to vent.

Does Double Sink With Disposal Need Two P Traps?

No, a single sink with disposal does not need two P traps. The trap in the garbage disposal should be sufficient to trap any odors that may escape from the sink drain.
