All of the drain lines running through your house are completely interconnected. In the bathroom, the lines running from the tub or shower and toilet attach to a common drain line using a Y-shaped tee or U-shaped trap joint. If a clog occurs just below this joint, the wastewater will come shooting out of the attached drain. In many cases, this results in toilet water coming out of the tub or shower drain at an alarming rate. Luckily, you can identify and remove the obstruction to fully restore the function of your drain.
Live rats constantly run through the sewer system in great numbers. In some cities, the rat problem is so prolific, the sewer control organization runs baiting programs using bright dyes to indicate the location of the rodent nests. Furthermore, homeowners may be encouraged to pour baking soda and vinegar down the drains once a month to avoid attracting rats into the local plumbing pipes.
Unfortunately, even after taking steps toward prevention, excess water flow in the sewers can send rats scurrying for high ground through the pipes in your home. If any of the rats end up stuck in the line, they could die there and fully block water from draining down that pipe.
Both kids and dogs cannot resist the urge to plunk their favorite toys in the toilet bowl for a swim. After becoming waterlogged, the toy may sink down into the bowl's U-bend where the next user cannot see it. With just a single flush, it's likely the toy will become lodged in the bottom of the main pipe joint, creating a near solid blockage.
Only the slightest amount of water will drip through the fabric of the toy, leaving solid waste, including paper products, floating above. Repeated flushing attempts will quickly send the dirty toilet water flowing out of the drain in the tub or shower.
Tree roots extend surprisingly far from the base of the tree to provide support and seek out nutrients. For example, even a tree six inches in diameter can have roots extending out nearly 20 feet. Therefore, even if you do not have trees too close to your home, your plumbing system could still be experiencing ill effects from root penetration.
Tree roots often lift up the pipes, causing the joints to crack apart. The roots will then start to grow up into the open pipe to collect the nutrient rich wastewater flowing out of your home. Eventually, the root will cause a full blockage at the joint that sends water shooting out of adjacent drains.
Pushing Out The Clog
Both soil and tree roots may respond to the addition of chemical dissolving agents poured down the drain. Only select this option if you have the time to allow it to work. Many chemical drain products require time to sit in the line and may even need repeated applications. Keep in mind you will likely still need to have the pipes repaired after dissolving the tree roots or soil products blocking the lines.
If you need the clog cleared fast, you can have any of these three obstructions manually removed from the lines by a plumbing professional. In many cases, your plumber will need to open up the floor or dig up the outside lines to perform pipe repairs.
To prevent full blockages, you can have your plumbing repair professional run a drain auger through the lines every once in a while to push unseen partial obstructions into the larger sewer lines. At that point, the problem is out of your hands. The city crews for your region regularly clear the large sewer lines to process the waste and keep water flowing freely under each street.
