If the system is operating and functioning correctly, we pay little attention to the various parts of the house drainage system. However, if the system becomes clogged, it is essential to locate and identify the problem areas quickly. This is the perfect time to get familiar with your drainage system–not if a drain pipe is damaged and spills dirty water everywhere on the bathroom floor.

To know more about the house drainage system, read this guideline and diagram from the beginning (fixture drains) until the end of this line (municipal sewer main).

The fixture drain can be described as the highest visible portion of a shower or sink drain.

A fixture’s drain marks the starting point of the drainage path and is also called the DWV. The course starts with an opening within the institution. It is typically equipped with a stopper or plug and continues to the sewer lines or the septic field.

Although this is by far the most apparent element, it’s not every day that drain problems originate from this. Other than when washers or gaskets could cause a tub or sink basin to leak, the least typical problems — drain obstructions–almost always happen downstream of the drain openings in the fixture. One exception is when hair blocks the stopper of a pop-up in the bathtub or sink in a bathroom.

Following the fixture drain, the water can flow below the fixture and into the next part, the drain trap.

Drain-Waste-Vent (DWV)

Drain-Waste-Vent or DWV signifies that the pipe network was not just intended to remove solid waste and wastewater to the municipal sewer or the septic field but also functions as an exhaust system that allows fresh air to flow into the drainage system.

Drain Trap or P-Trap

A drain trap, also known as the P-trap, is a curved section of pipe located directly below the fixture drain.

The drain trap lies below the bathtub, sink, or other plumbing fixtures. The drain opening connects to the web for drains or a catch called the “P.” It is usually in the range of 1-1/4 to 2 inches of pipe with an angular bend shaped as the”P “P.”

Drain traps are intended to store standing water that seals the drain system and stops the sewer gas from flowing through the sewer line into your home.

If you’ve come home from a long trip and noticed a slight sewer gas odor in your air, it’s likely because the water accumulating in the drains has evaporated, allowing the sewer smell to permeate your home. The water should be pumped out at any source and flushed ea, ch toilet to refill the drain traps.

Toilet Trap

The toilet trap can be described as a curving drain similar to P-traps or gutters in a bathtub or sink to keep gasses from entering the bathroom.

The trap for the toilet is a component of the. While it’s not readily apparent that every bathroom has an inside curving drain trap with its drain trap that you might be able to spot by looking at the toilet bowl on the other side.

The built-in trap has y the same purpose as a drain trap for the si: toto catch water and stop sewer gases from escaping into the house.

Clothes Washer Standpipe

A standpipe for a clothes washer is an open or concealed vertical pipe that assists in draining water from the washer when it is washing.

The flexible washer’s plastic drain tubing drains into a washing machine standpipe, leading to a curved drain trap. This drain catchment is then connected to a drain branch and then towards the drain in front of it. Most of these components can be hidden behind wall finishes. However, the standpipe is typically visible.

Based on the plumbing system’s condition, the standpipe can be constructed from brass, galvanized iron, ABS plastic, or PVC.

Branch Drain Line

The branch line drain is a vertical pipe (it is slightly pitched to help move the water) that connects your traps to the main drainage line.

The branch drain line connects all of the fixture’s drain traps with soil stacks that link to primary drain lines. The walls, floor, and ceiling surfaces usually conceal the branch drains. Sometimes, the branch drain lines can be seen in basement ceilings that are not finished.

Branch drain lines are constructed of a variety of materials. They are typically one 1/2 to 2 inches in diameter.

Soil Pipe

The soil pipe can be described as a horizontal pipe in the plumbing system that transports soil, also known as sewage, toward the sewer line.

When branch drains to reach the top of their horizontal runs,, they empty into soil pipes or vent pipes (SVPs) designed to transfer sewage into a more extensive sewer line.

Soil Stack Vent

The soil stack vent can be described as a vertical pipe that is positioned at the top of the roofline to eliminate gasses and vapors from the plumbing system.

The top part of the soil stack is the venting element that makes up the DWV system. If you move it up,, the vent stack can penetrate your house’s roofing, and opens to the air outside. The vent allows the whole drain system to be maintained at the same air pressure. This is crucial to stop the suction force of the water flowing through pipes from removing water from the drain traps in isolation.

The vent pipes transport noxious gases away and provide the pressure to release so soil and waste can quickly move down without removing water from the drainage drains.

Municipal Sewer Main

This is the municipal sewer main, which marks the last part of your house’s drainage system and the start of your municipal sewer network.

The final point of your house’s drainage line will be the sewer main in your municipal. The central drain line of your home is perpendicular to the main sewer line and is angled downwards to facilitate waste drainage.

You are not in control of the municipal line as it is owned by a municipal, county or water district.

Sewer inspections using video typically have the capability of running up to the start of the main sewer line for municipal sewers.
