When to Use Long Sweep Elbow

A leaky faucet can be a nuisance in any home, but when you are on a budget and don’t want to hire a plumber, you may be tempted to do-it-yourself. However, even if you are experienced at plumbing or DIY work, the process of replacing a faucet can seem daunting.

If you’re considering remodeling your home, you might have heard of “sweep type” or “long sweep” elbow fittings, and wondered how they differ from regular elbow fittings and how they are used. 

Also known as a long radius elbow or a long sweep tee, a long sweep elbow is a plumbing fitting that connects the horizontal pipe to the vertical drain pipe in a drainage system and is also known as a long sweep elbow

It is used to connect the pipe from the floor to the pipe that runs vertically in the wall. 

This fitting allows for the proper slope of the pipe to allow for proper drainage. 

Long sweep elbows are commonly used in residential and commercial construction to direct water from above-floor drains and sumps to the main drain line. They are a kind of a very long (and curved) pipe fitting that is used instead of a 90-degree elbow fitting to route wastewater.

It is important to understand the different types of elbows and the many types of uses they have.

Here we cover long and short sweep elbow.

When to use short sweep elbow fitting connection 

Although it may seem like a minor plumbing detail, using the right fitting for your drain line can make a big difference in the amount of stress put on your plumbing system.

To get the most out of your drainage fittings, you must consider the type of pipes you have and the flow dynamics. 

So, you’ve got a list of potential short sweep elbow fitting connections, but which one should you choose? 

There are a few things you should know about how flow dynamics will affect your drainage pipes. 

The most important consideration is how far your pipes extend before they drain into any additional piping system. 

It is important to plan your drain system with a specific end goal in mind.

For a single fitting on a pipe that turns a corner, a long sweep elbow fitting is often the simplest solution. 

But what about when you need multiple fittings on a pipe that turns a corner? It depends on how that pipe is supported. 

When a pipe is supported by a knee fitting, you can use a short sweep elbow fitting connection to connect the pipe after the turn to avoid any unnecessary stress and strain on the fitting.

When the pipe is supported by a short tee fitting, it’s best to use a short sweep elbow fitting to make a smooth connection between the pipes.

In most applications, the fitting is used to transition high pressure water from a vertical drain pipe to a horizontal sewer main pipe.

When to use long sweep tee fitting connection 

While the bulk of a plumbing system is made up of a series of pipes that transport water from the water main to the various fixtures around the home, the fittings that connect the pipes are equally important. 

Tee fittings are probably the most common type of plumbing connection you will come across, and that is because they are versatile.

PVC or metal, copper, or even stainless steel, when it comes to long sweep tee fittings, the choice is yours depending on the application. 

The fitting itself is the same for each material, but the type of pipe used will determine the overall quality of your plumbing system. 

Long sweep tees are used to connect two 90-degree fittings and allow water to flow through three separate areas. 

This can be useful when you want to extend a pipe to provide a clean flow of water to another section of a sprinkler system.

When to Use a Backflow Preventer

Over time, clogs, leaks, and flooding can occur within a home. 

If the water pressure is strong enough, water can branch off into different pipes that connect to different fixtures. 

While the plumbing in your home will eventually fail, you should do your best to extend the life of your system by regularly checking for leaks and clogs. 

To extend the life of your home’s plumbing, it’s important to know when and how to use a backflow preventer.

A backflow preventer is a device that blocks the flow of dirty or contaminated water, such as water containing sewage gasses, back into your clean water supply. 

This helps to protect your water supply from becoming contaminated and ensures that municipal water supplies remain clean. 

There are different types of backflow preventers, but the most common atmospheric device, also known as a vacuum breaker

The type of device to use depends on the type of water system it will be protecting.

Essentially, an atmospheric backflow preventer (ABF) is a valve, which prevents the flow of water from a plumbing system back into the water supply. 

In the event of a water pressure drop, backflow preventers limit the loss of water pressure, which is why they are also referred to as pressure-regulating valves.

ABF’s are installed in the discharge line of pumps, irrigation systems and other devices that discharge water into a potable water supply. 

The ABF functions by creating a vacuum in the discharge line when the pump is operating. 

If the flow of water through the discharge line exceeds the capacity of the pump, air is drawn into the line, breaking the vacuum. 

This action closes a valve to prevent the backflow of contaminated water into the potable water supply.

In home plumbing, a vacuum breaker protects the potable water supply from cross-contamination between hot and cold water, as well as to protect hot water heaters from thermal shock. 

A vacuum breaker is a low-cost device designed to protect the home plumbing system from backflow, which is the undesirable flow of water or other liquids, gases or materials from a higher to a lower pressure in the plumbing system. 

These devices are used on drains that are connected to sinks, tubs, washing machines, dishwashers, and other fixtures that use water.

Final words 

When it comes to choosing a fitting for a plumbing project, you want to choose the right one for the job. 

Not all fittings are the same, and they are designed for different purposes. 

One of the fittings that you should consider for your plumbing project is the long sweep elbow.

Long sweep elbow and long sweep tee are two different kinds of fittings that are used for plumbing, drainage, and irrigation. 

Both are available in different materials, such as aluminum, brass, copper, and PVC. 

Long sweep elbow is used for a plumbing that has pipe coming from one direction that turns 90 degrees to go to another direction. 

Long sweep tee is used in connecting two pipes that are coming from two different directions.

No matter how good an idea it may seem at the time, you should never try to save money by bypassing your backflow preventer. 

That’s because they are a crucial safeguard against cross-contamination. 

A backflow preventer is a type of device that prevents the flow of water, or in some cases air, from a contaminated source (like a polluted river or standing water) towards a fresh water source. 

This ensures that even if there are impurities in the water, you won’t be getting them in your drinking water.
