This is one of the most requested queries by anyone who owns a house. A House has many parts: kitchen, bathroom rooms, hall, and dining area. The kitchen, dining room, and bathrooms have things and water lines connected. However, we must focus on whether a toilet and sink share the same Drainage. Many people always wander about this issue due to various sanitary reasons. The answer is yes, and you can share your sink and toilet in the same drain. Nevertheless, you always have to ensure that there will be no backflow. Though the same drain can be utilized for a toilet and sink, you should keep in mind not to use the same waste trap, which prevents insects and bacteria from coming up to your house. Therefore, let us look into whether a toilet and sink can share an identical drain in detail. To gain more insight into this, we have to know the difference between a septic and a sewer.
What are Septic and Sewer?
It all depends on where you live and whether all wastewater will go to a sewer line. All households usually have a septic tank and a sewage tank separately. In a septic tank, the wastewater treatment happens through a process called biological decomposition and Drainage. Distance is an underwater sedimentation tank into which the bathroom, kitchen, and laundry wastewater go.
A septic tank is the best option to dispose of the wastewater effectively if homes are not connected to the main sewage line.
A Septic tank is usually installed 50 meters away from your household and is connected through an inlet pipe. In certain cities, a wastewater management program takes place. Households can divert their wastewater to the main sewer line through the help of this program; however, since not all cities have this facility, the families who do not have access to the system use a septic tank.
Is a Septic Tank and Sewage Tank Similar?
The only difference in a septic tank is that it always treats the wastewater at your household at your expense to install and maintain the system until it is filled up. However, with the Sewer, it is not the same. Let me tell you why. The local government operates the Sewer to direct wastewater to a treatment plant in your locality.
It will be subjected to a government tax and fee, which you will have to pay. The government will do the maintenance and cleaning process in a sewer, and you do not have to bother about it since you have already paid an allowance for it.
Always ensure that if you are a house owner, you have a proper drainage system. You will not want all the wastewater to flow back to your house.
Since we have a basic idea of a septic and a sewer line, now let us have our Full focus on whether it is possible to connect the toilet as well as the sink line into a single drain, or should we keep it separated despite knowing that it could be used together too.
To know more on this matter and educate ourselves more, we must first look into the types of water secreted once used.
Even though it is recommended that we can use one drainage system for both toilet and sink water, there is a contradiction saying that the water should have two separate drainage systems according to certain studies that have been conducted.
Disease due to the types of water that are secretes from the line should be kept apart when conducting plumbing activities because the water collected from the toilet is more likely to have been contaminated with diseases than the water from the sink.
Suppose there’s any repair to be taken place. In that case, It will be gross and disgusting for the plumber as well as the plumber can even get contaminated with these diseases if he doesn’t use proper safety measures beforehand.
What are the Types of Water?
There are two types of water in wastewater management.
- Grey Water
- Black Water
What is Grey Water?
The rules and regulations to dispose of grey water are less strict than black water. Because grey water is a type of water that comes from your sink ok or shower, it is less likely to have contaminated with diseases. However, you cannot dispose of wastewater in waterways used for drinking purposes, even though the rules are less strict. The reason is that the water is mixed with soap materials after use.
What is Black Water?
The rules and regulations to dispose of Blackwater are very strict as it is contaminated with high amounts of urine and feces. This is why it is recommended to have toilet drainage separately, as it can carry diseases. Therefore, this water should be disposed of in the safest way possible. Usually, in many houses, they typically have a separate septic tank for the toilet so that once it is complete; you can contact the sewage Treatment Centre and clear your septic tank.
Now let us move to the essential part of this article, can a toilet and sink share an identical drain?
Can a Toilet and Sink Share the Same Drain?
Of course, they can share the same Drainage but not the same wastewater trap to prevent blocks from happening. Nevertheless, the main thing that you need to focus on here is that it will repeatedly lead to blockages and cause the drainage smell to travel all around your house.
In addition, the water might take a separate direction to come out from the shower, which can be a hassle for you. Therefore, it is best to have different drainage lines for your toilet and sinks to prevent mishaps from happening as such. Always remember each time you try combining these two, it will always lead to a block and urine smell all around your house.
In conclusion, even though there are a thousand ways of disposing of water, the notorious waterways somehow find one way to travel back the line if any blocks inside it, causing immense trouble to the owners. Blocks only happen because the Blackwater is mixed with grey water forming lumps and particles, which causes the obstruction.
Therefore, I suggest having two separate drainage lines for the sink and the toilet why making your life when you can easily stay without worrying about blocks daily.
