Double kitchen sinks are something that many people dream of having, but double kitchen sink plumbing can be a nightmare. In order to ensure that there are no leaks, you have to fit a double kitchen sink plumbing kit, but there are many available, and these will contain a number of different connector pieces, depending upon whether you want a sink and disposal unit, or sink and dishwasher device. If you are intending to install some double kitchen sink plumbing, you can get a professional plumber to do the work for you, or you can purchase some extra washers and nuts, buy a kit, and by following a few simple rules, install your double kitchen sink plumbing on your own.

Step 1 - Preparation

The first thing that you need to do is buy the right kit for your drain. Look at the way in which the drainage comes off of your sink. Is it in a central pattern, or are the drains located at opposite ends of the sink part? Purchase the kit that most closely resembles the set up of your drains. You may also need a specific drainage system, for example if your second sink is also a waste disposal unit. While you are buying the kits, purchase supply lines which match with the one already in your drains. Once you have the kits, take them home and lay the pieces out, taking note of where they join together. This will make it easier when you come to fit the pieces below the sinks.

Step 2 - Installation of Supply Lines

When you are ready to begin, turn off your water supply at the mains. This will ensure that there is not much water in the system. Place a bucket, or plastic pot, beneath the drainage area, and lay out some tea towels or similar in order to catch any water that might be flowing through the system. Once this is done, remove your supply lines using the wrench, using lubrication if you are having any problems. When the supply lines are removed, put the new ones in their place, again using the wrench.

Step 3 - Installation of Plumbing

Now you are ready to install your pipes. Dry-fit your pieces together, and then cut to fit the area beneath your sinks using the saw. You should have a P trap, PVC pipes, an d a wall tube. You should already know how these can be laid out. Once the pipes and pieces fit below the sink, slide the nuts of the pipe into the piping, and add the washer onto the top of the vertical pipe. Tighten these so that the pipe is water tight, and then join the two pieces of pipe together. Lay the P trap on top of the pipes, and push up to the sink. Thread the wall tube into the correct position, and then tighten all of the bolts which hold the pipes on to the sink and the beginning of the water outlet. Turn your water back on.
