If you’re in the process of remodeling your home, or you’re experiencing plumbing issues, you may need to replace your pipes.
One decision you’ll have to make is whether to use long sweep 90-degree fittings or short sweep 90-degree fittings.
In this article, we’ll compare the two types of fittings, explain the pros and cons of each, and help you decide which one is right for your plumbing system.
What Are Long Sweep 90-Degree Fittings?
Long sweep 90-degree fittings are used in plumbing systems to make a 90-degree turn in the direction of the flow of water. These fittings are called “long sweep” because they have a gradual curve that allows water to flow more smoothly through the turn. The length of the curve is longer than that of short sweep fittings, which we will discuss next.
What Are Short Sweep 90-Degree Fittings?
Short sweep 90-degree fittings, on the other hand, have a shorter curve than long sweep 90-degree fittings. This means that water flow is disrupted more when it makes a turn in the pipe. Short sweep fittings are also known as “standard” fittings.
Differences Between Long Sweep 90 and Short Sweep 90 Fittings
The main difference between long sweep 90 and short sweep 90 fittings is the length of the curve. Long sweep fittings have a longer curve, which results in smoother water flow. Short sweep fittings, on the other hand, have a shorter curve, which results in more turbulence in the water flow.
Another difference is the price. Long sweep fittings are more expensive than short sweep fittings because they require more material to make.
Pros and Cons of Long Sweep 90-Degree Fittings
Pros:
- Smooth water flow
- Less chance of clogging
- Better for large-diameter pipes
- Less noise
Cons:
- More expensive than short sweep fittings
- Require more space for installation
- Require more material to make
Pros and Cons of Short Sweep 90-Degree Fittings
Pros:
- Less expensive than long sweep fittings
- Require less space for installation
- Require less material to make
Cons:
- Disrupt water flow more
- More chance of clogging
- Better for small-diameter pipes
- More noise
When to Use Long Sweep 90-Degree Fittings
Long sweep 90-degree fittings are best for large-diameter pipes, such as those used for main water lines, and when you want to reduce the chances of clogging. They are also a good choice for pipes that need to make a sharp turn.
When to Use Short Sweep 90-Degree Fittings
Short sweep 90-degree fittings are a good choice for small-diameter pipes, such as those used in residential plumbing systems. They are also a good choice for pipes that do not have to make a sharp turn and where there is not a high risk of clogging.
Which Is Better: Long Sweep 90 vs Short Sweep 90?
The answer to this question depends on the specific plumbing system you are working on. Long sweep 90-degree fittings are better for large-diameter pipes and when you want to reduce the chances of clogging. Short sweep 90-degree fittings are better for small-diameter pipes and when you have limited space for installation.
In general, if you have the space and budget, long sweep fittings are a good choice because they provide smoother water flow and less chance of clogging. However, if space and budget are limited, short sweep fittings may be a better option.
How to Install Long Sweep 90 and Short Sweep 90 Fittings
The installation process for both long sweep and short sweep 90-degree fittings is the same.
Here are the steps:
- Measure and cut the pipe to the correct length.
- Clean the end of the pipe and the inside of the fitting.
- Apply PVC cement to the inside of the fitting and the outside of the pipe.
- Insert the pipe into the fitting and twist it a quarter turn to ensure a secure fit.
- Hold the pipe and fitting together for a few seconds to allow the cement to set.
Tips for Choosing the Right Plumbing Fittings
When choosing plumbing fittings, here are some tips to keep in mind:
- Consider the size of the pipes in your plumbing system.
- Determine if you need long sweep or short sweep fittings based on the size of your pipes and the available space for installation.
- Choose fittings made from high-quality materials to ensure durability and longevity.
- Consider the cost of the fittings, including the cost of installation.
Common Mistakes to Avoid When Installing Plumbing Fittings
Here are some common mistakes to avoid when installing plumbing fittings:
- Failing to measure and cut the pipe correctly.
- Failing to clean the pipe and fitting before installation.
- Using the wrong type of cement for the fittings.
- Failing to hold the pipe and fitting together for long enough to allow the cement to set.
Conclusion
Long sweep 90-degree fittings and short sweep 90-degree fittings both have their pros and cons. The decision of which one to use depends on the specific plumbing system you are working on. Keep in mind the size of your pipes, the available space for installation, and your budget when choosing the right fittings for your project. By following the proper installation procedures and avoiding common mistakes, you can ensure a successful plumbing project.
FAQs
- What is the difference between long sweep 90-degree fittings and short sweep 90-degree fittings?
Long sweep 90-degree fittings have a larger radius than short sweep 90-degree fittings, which means they provide smoother water flow and are less likely to clog. Short sweep 90-degree fittings have a smaller radius and are better suited for tight spaces and small-diameter pipes.
- Are long sweep fittings more expensive than short sweep fittings?
In general, long sweep fittings are more expensive than short sweep fittings due to the larger size and higher quality materials required to manufacture them. However, the cost difference may not be significant, and it is important to consider the specific needs of your plumbing system when choosing the right fittings.
- When should I use long sweep 90-degree fittings?
Long sweep 90-degree fittings are best used in large-diameter pipes where there is enough space for installation and where you want to reduce the chances of clogging. They are also a good choice for areas where water flow is critical, such as in commercial and industrial plumbing systems.
- When should I use short sweep 90-degree fittings?
Short sweep 90-degree fittings are ideal for tight spaces and small-diameter pipes where long sweep fittings may not fit. They are also a good choice when you want to save space and money on installation costs.
- What are some common mistakes to avoid when installing plumbing fittings?
Some common mistakes to avoid when installing plumbing fittings include failing to measure and cut the pipe correctly, failing to clean the pipe and fitting before installation, using the wrong type of cement for the fittings, and failing to hold the pipe and fitting together for long enough to allow the cement to set. It is important to follow the manufacturer’s instructions and use the proper tools and materials for the job to ensure a successful plumbing project.
