- A foul smell coming from the pipe
- Gurgling sounds coming from the drain
- Slow draining toilets or sinks
If you notice any of these signs, don’t wait to call a plumber. The longer you wait, the worse the problem will get. Worst case scenario, it could even lead to flooding in your home or business.
Step By Step Guide to Repairing a Plumbing Stack Pipe
If you have a plumbing stack pipe that needs repair, don’t panic. This job is actually not as difficult as it may seem at first. With a little patience and the right tools, you can fix your plumbing stack pipe in no time.
What you need:
- Tape measure
- Pipe cutter
- Reciprocating saw
- Taps and dies set
- Pipe reamer
Now that you know what tools you need, it’s time to get started on your repair. Follow these steps, and you’ll have your plumbing stack pipe fixed in no time.
Step 1:
Determine the location of the leak
First, you need to determine where the leak is located. This can be done by turning on all the fixtures in your home, and then going outside to see where the water is coming from. Once you’ve located the leak, turn off all the fixtures and dry off the area around the leak.
Step 2:
Measure the damaged section
Once you’ve located the leak, use a tape measure to determine the length of the damaged section. You will need to cut out this section of pipe and replace it with a new piece.
Step 3:
Cut out the damaged section
Now that you know how long the damaged section is, use a pipe cutter to cut through the pipe at both ends of the damage. Make sure that you leave enough room on either side of the damage for the next step.
Step 4:
Tap the new piece of pipe into place
Now it’s time to tap the new piece of pipe into place. First, use a pipe reamer to enlarge the end of the damaged section of the pipe. This will help ensure a tight fit. Next, use a tap and dies set to tap threads into the end of the new pipe. Finally, screw the new pipe into place, and tighten it down with a wrench.
Step 5:
Turn on the water and check for leaks
Now that you’ve replaced the damaged section of the pipe, it’s time to turn on the water and check for leaks. If all goes well, you should now have a plumbing stack pipe that is as good as new.
Causes of a Leaking Plumbing Stack Pipe
There are several different reasons why a plumbing stack pipe may leak. Here are some of the most common causes:
1. Corrosion
Over time, the pipes in your home or business can become corroded. This is especially true if the water in your area is high in chlorine or other chemicals.
2. Leaking joints
The joints between sections of pipe can also leak over time. This is usually due to a poor sealant job, or damage to the joint itself.
3. Blockages
Blockages in the pipe can cause water to build up and eventually leak out. This is often caused by tree roots or other debris that get lodged into the pipe.
4. Obstructions
Obstructions in the pipe can also cause water to leak out. This is often caused by a blockage that is upstream of the leak.
If you have a plumbing stack pipe that is leaking, it is important to determine the cause of the leak, and then take steps to repair it. Depending on the severity of the leak, you may be able to do the repair yourself, or you may need to call a plumber. Either way, it is important to take care of the problem as soon as possible so that it does not cause further damage to your home or business.
