Run Pipes Through Stud Cavities

Once you’ve identified the location of your studs and have drilled a hole in each one, it’s time to bend your pipe. 

You’ll need a pipe bender for this, which is essentially just a tool that has multiple pieces that allow you to make 90 degree bends out of a straight piece of steel. 

The same rule applies here as it does for fitting pipes through walls: make sure everything is level! If there’s any sort of slant when you’re bending the pipe, even slight ones from both sides, water may leak out as soon as it flows through.

Once all parts are bent correctly, fit them together using clamps or other hardware until they’re tightly secured against each other (and make sure there aren’t any leaks). 

Once everything looks good and doesn’t leak at all points along its length, go ahead and screw down two ends together with screws made specifically for plumbing applications (you can find these at most hardware stores). 

Then you can use another set of clamps or screws to hold things tight while they cure (usually overnight).

If you are running plumbing pipes, it’s essential to understand how to find your plumbing vent stack. One of our articles discusses this in-depth, so be sure to check out our guide on finding your plumbing vent stack to ensure your plumbing system functions properly.

Seal The Walls And Lay Insulation

Insulation is important for a number of reasons:

  • It reduces heat transfer, which lowers your utility bills.
  • It helps keep pipes from freezing in the winter.
  • It keeps the pipe walls from overheating in the summer, which can cause them to crack or burst.

Insulation comes with a variety of different thicknesses and materials, and you can choose whichever type you prefer based on what’s best for your home’s needs. For example, if there are certain pipes that are especially exposed to high temperatures (such as those surrounding an outdoor water heater), then it may make sense to use pipe insulation with reflective aluminum coating on one side so that they don’t overheat when exposed directly to sunlight during warm months. 

Insulation is also easy enough that even inexperienced DIYers can install it themselves; just be sure not to block off any vents or other openings in order to keep proper airflow inside your walls!

This table outlines the necessary materials and tools required for sealing walls and laying insulation. Weatherstripping, expanding foam insulation, fiberglass insulation, vapor barrier, and sealant tape are some of the essential materials needed for this process. Useful tools include a caulk gun, utility knife, tape measure, stapler, and safety goggles. Be sure to follow proper safety precautions when insulating and sealing walls.

Support Your Pipes With Joist Hangers

Once you’ve run your pipes to the wall, it’s time to support them. To do this, you’ll need joist hangers. 

Joist hangers are installed in the joists (the metal beams that support the floor) and then attached to wall studs (wooden pieces of lumber attached between two joists). 

They provide stability for plumbing pipes. You can hang your hangers from both sides of the joist so they’re equally supported by both ends.

To install a joist hanger:

  • Mark where you want your pipe to come out on one side of your mark with a pencil or marker
  • Drive a nail into each side of the mark in order to make an indentation where you will later attach screws
  • Drill holes through these marks (this allows room for screws)

Running into plumbing problems can be frustrating, but fortunately, most issues can be fixed. Our pro guide on fixing plumbing issues covers everything you need to know to troubleshoot, diagnose, and resolve common plumbing problems.

Lay The Pipe In Clips Attached To The Floor Joists

If you are installing your own plumbing, use a pipe clip at each joist every 3-6 feet (1-2 meters). You can also use them every 12 inches or so if you’re not sure how much weight your pipes can support. The number of clips will depend on the type of flooring and whether or not it’s finished.

This table outlines the necessary materials and tools required for attaching plumbing pipes to floor joists using pipe clips. Some essential materials include pipe clips and screws. Measuring tape, pencil, level, hammer, drill and driver bits, and a stud finder (optional) are helpful tools to ensure proper installation. The number of clips necessary will depend on the type of flooring and whether or not it’s finished. Be sure to follow local building codes and regulations, as well as manufacturer’s guidelines for plumbing installation.

Put In An Access Panel

Once you’re done with the rough-in work, you can put in an access panel to make plumbing pipe maintenance easier. 

Access panels are used for things like accessing plumbing pipes that run through walls and floors.

Access panels can be installed in the following areas:

  • Wall (usually from ceiling to floor)
  • Ceiling
  • Floor
  • Wall

Connect Your Fixtures To The Water Supply

You’ve done a great job of installing your fixtures, but there’s still some work to be done before you can enjoy the fruits of your labor. You need to connect them to the water supply. To do this:

Connect your fixtures to the water supply source. This is usually done with a pipe called an “expansion joint”, which is flexible enough so that it won’t break when you move around in your home or apartment (as long as you don’t try too hard).

Connect each fixture directly into its own plumbing fitting using a connector that attaches at both ends, such as a slip or compression adapter. These adapters are available at any hardware store and they come in many different sizes!

Cut Holes In The Wall For Fitting Access

To cut the hole for the pipe, use a hole saw. These are available in different sizes that match the size of your plumbing pipes. Make sure you have the right size hole saw for the pipe you want to install and that your drill can handle it. 

You should also put some wood behind wall studs before cutting into them so that they don’t get damaged by falling debris from inside the wall.

Once you have access to where you want to run your plumbing pipes, you can start drilling holes for them with an appropriate bit size (usually 3/4 inch).

If you’re installing new plumbing pipes, you may need to remove the old pipes to make room. Our article on removing plumbing provides simple and effective ways to remove old plumbing pipe safely and effectively.

Screw A Coupling Onto Each Pipe End

To join two pipes, screw a coupling onto each pipe end. The coupling is the end of the pipe, and it attaches to your fixture. It has threads that fit into your fixture and an O-ring that seals against water damage.

The standard size for a drain pipe is 3/8″ diameter, so you should use a coupling with this size of threading (or larger). 

If you want to add additional fixtures or change out parts later on down the line, make sure they match up with what your pipes already have installed!

Cut Holes In Each Wall Stud Using A Hole Saw

Once you’ve marked where the pipes should go, it’s time to cut holes in each wall stud using a hole saw. A hole saw is an electric or cordless drill bit that cuts holes in wood and other materials.

You’ll need to find the right size hole saw for your job, so keep this in mind when you’re shopping around. You can usually find them at hardware stores or home improvement centers like Lowe’s or Home Depot.

When cutting through drywall and wood studs, use a drill and the correct size hole saw to cut the holes for your plumbing pipe fittings. Then hammer those fittings into place with a rubber mallet until they’re snug—but don’t overdo it! 

It’s important that there be no gaps between fitting pieces because this could cause leaks down the road (or even worse). 

Check for fit after tapping each piece of pipe into place before tightening it down with wrenches or ratchets; otherwise things will get messy fast if they aren’t lined up properly due to misalignment issues caused by loose screws holding them together!

Planning a home renovation, including plumbing-related upgrades, can be overwhelming. But don’t worry – our guide on how home renovations work provides an overview of the process, from planning to execution, so you can approach your renovation project with confidence.

Fit The Pipe Through The Hole

You’ll need to cut or bend the pipe so that it can fit into place, so grab a pipe cutter and get to work. This can be tricky if there are a lot of bends in your plumbing, but if you’re careful enough, you’ll make it work! 

Once your pipes are cut and bent into place, use some pliers to tighten them onto a coupling (the part of your plumbing that connects two sections of pipe together). This will keep everything secure until it’s time for installation.


If you’re planning to install plumbing pipes, it can be a bit confusing. The process is not as straightforward as it seems. 

But don’t worry! We have outlined some important things you need to know about plumbing pipe installation.
