One of the most obvious signs that you may notice when you have blocked drains would be the changes on how the fixtures work. Here are plumbing fixtures that may give you signals that you are dealing with blocked sewer drains:
The toilet has the most direct path to your sewer and has the largest drain line in homes or establishments. Therefore, if there is an issue in your drains, this is where you can find the first hint. It is very seldom that sewer drains or lines are blocked yet your toilets are still normally working.
Shower and Tub
These two also give hints because they are located at a level that’s lower than the sink. The shower and tub could be blocked immediately when stoppage on sewer drains occur.
Flush of The Toilet
When you notice water coming or backing up into the shower or tub every time you flush the toilet, you have blocked sewer drains. The flowing back of water to the tub and shower is caused by the flushed water from the toilet that is not going down, thus flowing back on the pipes. This is something you never want to experience, as this may cause the house to have a strong foul odour.
When you see any of these signs, it’s best to call a professional plumber to fix the blocked sewers. If you try and do it yourself, you’re going to consume a lot of time. Professionals underwent rigorous training pertaining to plumbing problems so they should be able to solve it immediately. They have passion in what they do so they would love nothing more than to come over and fix your drains.
