Toxic Clean up is called in HAZMAT
sinks and tub back up because the sewer line is blocked somewhere
There are multiple ways of stopping sewer backing up in rain storms. Ensuring there is no blocking or back ups in the piping can keep the sewer from backing up. Using generators to release excess water and allow it to flow elsewhere can prevent a sewer from backing up during a rain storm.
there is a blockage in your sewer line
If you think you smell sewer gas in your bathroom, it could be that a sewage blockage is in your pipes, causing the sewage to back up in the lines.
yes
Howdy! The tenant does because the are the ones who have been pooing. x
there's a back up in the system. probably where the main pipe goes to the sewer or septic.
full block of main drain. shower is lowest open area for back up to occur.
When the pipe goes down, and back up, and back down again, the first "up-curve" is called the trap because when the water goes down the drain, not all of it goes back up and down again (thanks to gravity). So there is a little bit of water there and it prevents any gas/odors from coming back up the sewer pipe. Provided that the pressure on the sewer-side of the trap does not exceed atmospheric pressure on the drain-side, the water will not get forced back up. Provided that the water is not allowed to evaporate, there will always be water there. And provided that there is enough water such that the top of the inside curve of the up-turn is lower than the top of the trapped water level, the trapped water will seal out the sewer gas.
Not unless there has been a back-up.
It depends how much back pitch there is
If your policy contains sewer back up coverage and business owned property coverage. The policy should according to its terms and coverages cover your claim. http://calcocommercialinsurance.com
