Long Sweep 90 vs Short Sweep: Which is Better for Your Plumbing System?

Sanitary drainage fittings are essential components in any plumbing system. Two of the most commonly used fittings are the long sweep 90 and short sweep elbows. While both of these fittings are used to connect pipes in a drainage system, there are key differences between the two.

According to plumbing experts, the primary difference between the long sweep 90 and short sweep is the resistance to wastewater. The long sweep is not resistant to wastewater while going through the pipe, while the short sweep with its narrow radius causes resistance to wastewater in the middle of the way. Despite this difference, both fittings are necessary to adjust the direction of PVC piping with their elbows perfectly.

Long Sweep 90 Vs Short Sweep Table Comparison

When it comes to plumbing, choosing the right pipe fittings is essential to ensure proper water flow and drainage. Two popular options are the long sweep 90 and short sweep 90. In this section, we will compare the two types of pipe fittings in terms of direction, uses, hiding the pipelines, and using them in the right place.

Direction

The direction of the pipe fitting is an essential factor to consider when choosing between long sweep 90 and short sweep 90. The long sweep 90 is designed to direct the horizontal pipeline to the vertical pipeline to direct the wastewater. On the other hand, the short sweep 90 directs the vertical pipeline to the horizontal pipeline into the drainage system.

Uses

Long sweep 90 is ideal for disclosing the solids containing wastewater. It is commonly used in large fixtures of the drainage system. On the other hand, the short sweep 90 is used in the drainage system but not for directing solids. It is more suitable for small fixtures of pipe fittings.

Hiding the Pipelines

If you are looking to hide the pipelines, the short sweep 90 is a better option. The long sweep 90 doesn’t allow the pipe to stay hidden in the bay due to the nominal joists. To hide the pipe, you’ll need to lower the existing room’s ceiling and former closet. In contrast, the short sweep 90 can easily be hidden in the joist bay.

Using at the Right Place

Using the right pipe fitting at the right place is crucial to ensure proper water flow and drainage. When connecting the long tee fittings of the drainage pipelines, the long sweep 90 is the better option for a smoother connection. Conversely, when connecting the short tee fittings of the pipelines, the short sweep 90 is the better option for a smoother and better connection. Using the long sweep 90 for the short tee fittings won’t be efficient in this case.

In summary, both long sweep 90 and short sweep 90 have their advantages and disadvantages. When choosing between them, it’s essential to consider factors such as direction, uses, hiding the pipelines, and using them in the right place. By doing so, you can ensure proper water flow and drainage in your residential, commercial, or industrial plumbing system.

Frequently Asked Questions (FAQs)

What Is A Sweep in Plumbing

A sweep in plumbing is a large elbow fitting with radius measurements inside. It is a manifold system that connects pipelines to direct wastewater from upwards to downwards. It is designed to reduce turbulence and prevent clogs caused by solid waste.

What Is A Short Sweep?

A short sweep is a small elbow fitting with a narrow radius. It is commonly used in plumbing systems to change the direction of the pipeline. However, it is not ideal for directing toilet waste as it causes turbulence and clogging.

What Is A Long Sweep 90 Used For?

The long sweep 90 is a plumbing fitting used to connect pipes at a 90-degree angle in a long, sweeping motion. It is typically used for waste and vent plumbing. The defining benefit of the long sweep 90 is it allows waste to make the 90-degree turn without slowing down. It is used for directing wastewater from the above floor to the ground floor of a building. It is commonly used in commercial, business, and residential multi-storied buildings.

Do I Need A Long Sweep 90 For A Toilet?

Yes, you’ll need a long sweep of 90 for directing the toilet wastewater. The long sweep 90 has a greater radius than the short sweep fittings, which is important for directing the toilet wastage. The short sweep fittings with a narrow radius cannot direct the toilet wastage thoroughly. A portion of toilet wastewater sticks into the pipe, causing the waste to overflow into the toilet. The long sweep 90 is designed to direct the wastewater more effectively and prevent clogging.

Can I Use A 90-Degree Elbow?

Yes, you can use a 90-degree elbow to direct the wastewater with the vertical drainage. Two 45-degree fittings and a small straight-line pipe between the sweep fittings should also be included with the elbow. Only then can you ensure that the pipeline directs the wastewater thoroughly. However, it is important to note that the 90-degree elbow does not have the same benefits as the long sweep 90 when it comes to directing toilet waste. The long sweep 90 is the recommended fitting for directing toilet waste.

Verdict Words

In conclusion, choosing between the long sweep 90 and short sweep 90 depends on the specific needs of the plumbing system. The long sweep 90 is ideal for larger diameter pipes and smoother water flow, while the short sweep 90 is better suited for tight spaces and adjusting short tee fittings.

When it comes to cost, the short sweep 90 is generally less expensive than the long sweep 90. However, the price difference may vary depending on the brand and supplier.

In terms of installation, both the long sweep 90 and short sweep 90 require similar tools and procedures. However, the short sweep 90 may be easier to install in tight spaces due to its narrower radius.

When it comes to cleaning and maintenance, both the long sweep 90 and short sweep 90 require regular cleaning to prevent clogging and buildup. However, the longer radius of the long sweep 90 may make it more difficult to clean thoroughly.

In terms of durability and noise reduction, both the long sweep 90 and short sweep 90 are comparable. However, the longer radius of the long sweep 90 may provide slightly better performance and lift.

Overall, both the long sweep 90 and short sweep 90 have their advantages and disadvantages. It is important to consider the specific needs and budget of the plumbing system before making a decision.

Frequently Asked Questions

What are the differences in flow characteristics between a long sweep 90 and a short sweep 90?

A long sweep 90 is designed to have a longer, more gently curved path than a short sweep 90. This makes it ideal for use on a toilet drain line, as it allows waste to make the 90-degree turn without slowing down. The defining benefit of the long sweep 90 is that it allows for smoother waste flow. On the other hand, a short sweep 90 has a narrower radius, causing resistance to wastewater in the middle of the way.

How do the dimensions vary between a long sweep 90 and a short sweep elbow?

The short sweep is obtainable in diameters of 2 to 6 inches, while the long sweep ranges between 2 to 7 inches. Therefore, the long sweep’s inner and outer diameters are usually larger than the short sweep’s.

In what situations is a 90-degree long sweep preferable over a short sweep?

A long sweep 90 is preferable over a short sweep when smooth waste flow is required, such as in a toilet drain line. It is also ideal for use in vent plumbing. A short sweep 90 is best suited for situations where a tight turn is needed, such as in a sink drain line.

Can a long sweep 90 be used interchangeably with two 45-degree fittings?

Yes, a long sweep 90 can be used interchangeably with two 45-degree fittings. However, it is important to note that using a long sweep 90 can reduce the number of fittings required, which can save time and money.

What are the code requirements for using a long sweep 90 versus a short sweep in plumbing?

The International Plumbing Code (IPC) allows for the use of both long sweep 90 and short sweep 90 fittings. However, it is important to ensure that the fittings meet the code requirements for the specific application.

Is there a significant difference in pressure drop between a long sweep and a short sweep 90?

There is no significant difference in pressure drop between a long sweep and a short sweep 90. Both fittings are designed to provide smooth, efficient flow through plumbing systems. However, it is important to choose the appropriate fitting for the specific application to ensure optimal performance.
