Pipe bend: how to choose a drainpipe elbow

The correct geometry of a gutter is not just about straight sections. In real life, the pipe needs to go around a cornice, a ledge of a facade, or to properly direct water away from the house. This is what a pipe outlet is used for.

This element is responsible for changing the direction of the flow and ensuring correct drainage of water without overloading the system. Without it, even high-quality rainwater drainage systems operate unstable.

The Akveduk company designs drains as complete solutions. Therefore, each drain outlet is precisely compatible with other elements and works without leaks.

What is a drainpipe and why is it needed?

A downspout is an element that changes the direction of water movement in the system.

It is installed in two key locations:

• under the eaves: to connect the gutter to the vertical riser;
• below: to drain water from the foundation.

The lower branch of the downspout is often called the drain elbow. It directs water into the drain or to a blind area.

Without such an element, it is impossible to organize the correct drainage of water from the downspout. The stream either hits directly under the foundation or splashes onto the facade.

What are the drain outlets?

A modern drainpipe differs in its bend angle, design, and purpose. It is not a universal element, but a precise solution for a specific task in the system.

In gutters, it often works together with elements such as a downspout, forming the correct trajectory of water movement from the roof to the ground.

The most common types:

• bends of different angles;
• single-coupling and double-coupling tap;
• elements for top and bottom mounting.

Proper selection allows you to reduce the number of joints, increase tightness and simplify installation. This is especially important for complex facades. 

Types by bending angle

The angle of the bend determines how smoothly the flow direction changes.

• 67° — smoother turn, reduces load and turbulence;
• 87° is a sharper angle, suitable for compact and confined areas.

If you need to bypass the eaves, usually use two branches with a smaller angle. In this scheme, the branch pipe works without overloading, and the water moves evenly.

When forming a drainage outlet at the base of a building, a sharper angle is often used. This allows for precise direction of flow away from the foundation.

Types by design and purpose

The design affects the connection method and ease of installation.

Gutter corners for metal gutter systems

The safety of the foundation and walls of a house directly depends on how tightly and correctly each element of the drainage system is selected. It is gutter and the gutter angle itself provides a reliable connection of two sections of the main on the roof where there is an architectural turn, maintaining continuous water drainage along the entire perimeter of the roof. 

If you need to order a gutter angle, you should pay attention to compatibility with the gutter and other components.

What is the angle of a gutter?

Structurally, the gutter angle is designed to change the direction of the gutter line at the corners of the roof. It forms a reliable joint between two sections of the gutter and ensures continuous movement of water to the funnel.

A high-quality element and professional fastening helps avoid leaks and maintains the system's efficiency even during heavy rainfall.

Where is the gutter angle used?

In practice, the modern gutter angle is used on:

• private homes;
• cottages;
• commercial and industrial facilities. 

It is necessary on roofs with complex geometry, bay windows, terraces and facade overhangs.

Before purchasing a gutter angle, it is important to consider:

1. number of roof turns;
2. gutter location;
3. installation locations for elements such as the bracket, holder, and plug.

Main types of gutter angles

The construction market offers various options for part configurations, so the right choice depends on the configuration of the roof and the direction of the gutter. The main thing to remember is that the fastening of all components should be as rigid as possible.

Outer corner of the gutter

The outer corner of the gutter is used to go around the external protrusions of the building. 

It provides a smooth transition of the gutter without disrupting the movement of water. It is mounted exclusively on external roof breaks.

Inner corner of the gutter

The inner corner of the gutter is installed in the inner bends of the roof, where water flows from several slopes at once.

Such nodes usually take on the maximum load during heavy rainfall.

Universal gutter angle

For non-standard architectural solutions, a universal gutter angle is used. This solution allows you to adapt the system to a complex roof configuration.

It is only important that the product is compatible with a specific metal line, otherwise the mounting clamp simply will not fit into its designed place.

How to choose a gutter angle for a drainage system

Before purchasing a gutter angle, you need to consider:

1. gutter diameter;
2. type of turn;
3. what color is the device painted (brown, green or black);
4. quality of the protective coating. 

It is important that the element is compatible with other parts of the system.

The reliable gutter angle is made of metal and provides a tight connection for many years of use.

Why is the angle of the gutter important?

Quite often, beginners confuse the concepts of a corner element and the angle of inclination of a gutter. 

• Slope. Needed for water movement to the funnel.
• Corner element. Responsible for changing the direction of the gutter.

Incorrect slope can cause water stagnation even with high-quality installation.

Is it possible to install the gutter angle yourself?

Many homeowners consider installing a gutter angle with their own hands. This is possible on simple objects, provided that the elements are correctly selected, the slope is observed, and the fasteners are properly fixed.

For complex roofs, it is better to contact specialists.

Corners of the "Aqueduct" gutter

The Ukrainian-Finnish company "Akveduk" has been manufacturing metal drainage systems since 2011. High-quality steel and modern galvanizing are used in production. All components are designed taking into account the changing climate of Ukraine and undergo strict multi-level quality control.

If you need to order a gutter angle, the company's products provide precise geometry of parts, reliability and durability. Prompt delivery and a wide selection of product items in stock will pleasantly surprise even the most demanding customers.

What to check before buying

Before purchasing a gutter angle, it is worth clarifying:

• type of angle;
• required size;
• system compatibility;
• type of coating, presence of a protective layer of zinc;
• guarantee;
• availability of goods;
• delivery terms.

Particular attention should be paid to the universal gutter angle if the roof has a non-standard geometry.

FAQ

What is the difference between the outer corner of a gutter and the inner corner?

The external one is used on the external ledges of the building, and the internal one is used in places where the roof breaks internally.

When is a universal gutter angle needed?

For complex architectural solutions and non-standard gutter turns.

What should be the angle of inclination of the gutter?

In most cases, a slope of 2-5 mm per meter of gutter length is sufficient.

Can I install the gutter angle myself?

Yes, if all elements are selected correctly and installation requirements are met.

Where to buy the Aqueduct gutter angle in Ukraine?

Products are available through the company's dealer network with advice on selection and installation.
