Pipe Reducers are a great way to reduce the flow of high output plumbing systems, as well as allow a fixture or joint to be added into the lines when the ending pieces are of different sizes. This task is actually very easy when it applies to plumbing, and since a professional plumber is a costly investment, this type of job can be performed by the homeowner as a DIY project in order to lower the expenses that will be required for this project.

Step 1: Adjust the Existing Pipes

Before adding a pipe reducer into the plumbing lines, it may be necessary to cut a small section out of the existing pipes, which will allow for the extra room needed to add the reducer into it. In order to complete this task, measure the inside length of the pipe reducer if there are any internal lips within it. For instance, if the internal lip is a ½ inch, then one of the pieces of pipes will have to be cut back to allow for exactly that distance in between the two pipes.

Step 2: Attach One Side of the Pipe Reducer

Begin attaching the pipe reducer by first cleaning the edge of one of the existing pipes. Use a stiff wire plumbing brush to level the end out and to remove any burrs, and then cover the entire end with plumbing cleaner compound. Do the same with the end of the reducer that will be placed onto it, making sure that the entire end of both pieces of pipe are covered with it. After you have cleaned the ends, cover them with the plumbing glue, making sure to cover both edges. Work fast when doing this because plumbing cement can harden very fast.

Press the pipe reducer into place, pushing it onto the existing pipe as far back as possible. Allow these pieces to set before continuing onto the next step.

Step 3: Attach the Second Plumbing Pipe

As with the previous step, clean the edges of both the existing pipe and the pipe reducer, and apply the cleaner and the cement onto them. Attaching the two pieces together may be a little harder than the previous ones because the fit will be tighter. Just make sure to work the pieces together as quickly as possible, without bending any of the pipes, and squeeze them together. Once again, allow these two pieces time to set before trying to run any water through the plumbing system.

That is all there is to installing a pipe reducer in your current plumbing lines. Of course these steps apply only when you are working with plastic pipes, but if you need to attach metal to metal, the fittings would have to be wrapped with plumbing tape and then secured together with a plumbing wrench.
