Home plumbing is a system that includes pipes, fixtures, appliances, and even vents.  The reality is that many homeowners do not pay close attention to the importance of vents in the plumbing system, which can result in various problems.  Read on some tips from plumbingpasadena.biz to understand why your home plumbing needs efficient vents to perform properly.

Venting System

The venting system refers to the portion of your home plumbing system that connects the special pipes (plumbing vents) from the various plumbing appliances in your home to the outdoor.  The normal configuration is for the vents to lead to the roof where they become an exhaust.

Why are vents important?  In the context of plumbing, it helps to carry water along the venting pipes as well as sewer gases.  This means that they perform the very important role of safely limiting the possibility of your plumbing getting backed up that can pose severe health problems.

By introducing oxygen into the plumbing system the process of breaking down waste material is assisted.  The vents are also used to ensure that water seals are maintained using plumbing traps.  Effective plumbing traps prevent sewer gases from moving from the sewer system and into your home.

This means that unless plumbing vents are in place, it would be difficult for waste matter and water to properly move through the plumbing system of your home.  Unless neutral air pressure is maintained inside the drains, gravity will not be able to pull the water from the pipes down the drains.  When combined with proper downward slope of the pipes, efficient flow is preserved in your home plumbing system.

Neutral Air Pressure

What does it mean to have neutral air pressure and why is it important to maintain it?  Neutral air pressure means that the air pressure in the pipe is the same as that of its surrounding.  This is present when there is no water flow in the pipes.

As water movement begins in the pipes, the downstream current created by the air inside the pipes can be compressed resulting in positive pressure.  The upstream air acts as a vacuum that pulls wastewater back into your home.  So obviously, the positive pressure must be released.

When there is no airflow behind the waste, negative pressure will result creating a suction action.  This means that the amount of waste movement will be dictated by the suction action created.  In your home, the toilet has the shortest trap seal, which means that excessive negative pressure can be created resulting in the trap being completely empty.

What is the danger of an empty trap?  It creates a pathway for sewer gases to enter your home and cause severe health risks.

The Need for Plumbing Vents

If we are to look at building codes, it is a requirement for every home to have a trap installed for all plumbing appliances and even fixtures in certain instances.  This alone emphasizes the need for proper plumbing vents.

The requirements of the building codes is anchored on the possibility that the absence of plumbing vents can result not only in health risks, but also cause discomfort to the occupants of the home.  To ensure that proper plumbing vents are installed, you would need the services of licensed professional plumbers.

Building codes require that vent stacks connect to the main roof vent of your home plumbing system.  The individual vents must also be positioned about five feet from the plumbing fixtures like tubs, toilets, sinks, and showers.

Professional installation is therefore essential to comply with the requirements of the building codes.  Licensed professional plumbers can also ensure that plumbing vents do not get clogged or blocked especially during winter where ice buildup is almost imminent.

Now that you understand the importance of plumbing vents, it would be to your best interest to have your home plumbing vents inspected by a licensed professional plumber to ensure that it is free from clogging and rust.
