If you've moved into a new home and you can smell odors around all of the sinks and drains, you need to call a plumber. Since you don't know if the previous homeowner had any backup issues, or if they had the drains cleaned frequently, the problem may not be apparent.
There are a lot of different things that could be creating odors, and causing the odors to linger up through the drains. The plumber will check the following areas.
Plumbing Ventilation Pipes
Have you ever wondered what those pipes that stick out of your roof are for? The pipes are the plumbing ventilation system, and a crucial part of helping water flow down to the septic system through the pies. If these pipes are clogged, the water doesn't have the gravity pull to head down to the septic system, and waste could be sitting in your toilets or in your pipes. Ask the plumber about screens for the tops of the pipes to prevent future clogging.
If there is hair or debris trapped in the drain traps, bacteria are probably accumulating and causing odors. The plumbers can clean out the drain traps to remove any problematic clogs, and they can look at the pipes. If they determine the clogging or bacteria accumulation goes beyond just the traps, they may suggest that you have the plumbing cleaned.
Do you have a septic tank where all of the waste goes? Do you know the last time it was emptied? If not and the tank is full, the smell you are bothered by could be waste coming back up through the pipes and into the drains around your home.
You'll want the plumbers to run a camera through the pipes into the septic system to see if there are any major problems that need to be dealt with, and to see if the tank needs to be pumped.
If the plumbing is old and galvanized, you may want to have it replaced to remove any dangers or lingering bacteria. It can be very difficult to know how the previous homeowner's took care of the house and the plumbing, and an inspection can prevent you from having a huge problem on your hands in the future. Get an inspection from a company like Absolute Plumbing & Drain Cleaning Services Inc and get rid of the unenjoyable odors that are lingering around your home and throughout the drains in the space.
