Do-it-yourself sewer hood installation
By entrusting responsible work to people who do not understand the issues and intricacies of construction, out of a desire to save money, you can get a result that will later need to be redone. Often you have to do everything almost from scratch, working with damaged materials. I have repeatedly had to deal with such situations, since some construction teams have a very conditional idea of \u200b\u200bthe issue of proper installation of sewers. In this material, we will tell you how to eliminate an unpleasant smell from the sewer, consider what sewer ventilation is, and why it is especially important.
I was approached with a request to deal with the sewer, during the operation of which there was an unbearable smell of sewage. At first glance, it became clear that in a two-story house with four bathrooms and toilets, the sewerage was installed incorrectly. Firstly, all points are connected in series through one common riser, although it was necessary to make two. Secondly, there was no sewer hood, which was the main reason for the smell.
Why is sewer ventilation so important?
When you use the sewer, air enters along with the water. It penetrates through sewer pipes and highways. It is no secret that this air has an unpleasant smell. Of course, the connection points, whether it be a bathtub or a toilet, have a water lock - a siphon that prevents this air from entering the room. However, if your riser does not have a sewer hood, then you will smell.
This happens for the following reasons: the water that you flush into the sewer serves as a kind of piston that pushes the air. Air is lighter than water and tends to rise up or into any openings in the sewer. The most vulnerable are the places where the corrugations from the siphon enter the sewer pipe. Although the corrugations have rubber seal ends, air moving in the pipe with some pressure easily penetrates into the smallest cracks, and you immediately feel an unpleasant smell.
To prevent this from happening, it is necessary that all consumers have a connection to a common sewer riser, the end of which goes above the roof and has a hole that discharges air into the atmosphere. Water in a ventilated sewer does not stagnate even with prolonged absence of operation.
To eliminate the unpleasant odor from the sewer, the following materials and tools were needed:
- sewer pipe with a diameter of 50 - 2 meters, 1 meter and 0.5 meters
- bend 90 degrees - 3 pcs.
- straight tee - 1 pc.
- ventilation hat - 1 pc.
- silicone sanitary
- fasteners for pipe 50 diameter
- perforator
- level and marker
How to install a sewer hood
So, getting to work, I chose the only place possible for the hood, which became the highest point of the entire system. It's the kitchen sink by the window on the left.
To do this, I had to make a hole in the wall with a puncher to bring the pipe to the street. Of course, no matter how carefully you try to make a hole, dust and dirt are inevitable.
On the street, I inserted a branch into the socket of the segment for holding the pipe along the wall.
I inserted a dowel into the hole and screwed the pipe mount into it. It is important here that the distance on the branch is the same for fastening. So right and aesthetically pleasing.
We mount all fasteners to the very top, observing the distance from the wall to the pipe.
Next, we connect all parts of the pipe, I got one two-meter and one meter, two 90-degree bends and a ventilation cap. It is important that before installation it is necessary to coat all the rubber bands with silicone. Many people use grease or just liquid detergent, and some use soap, but this is not entirely correct. Having hardened, the silicone will provide additional sealing of the joints. In addition, it creates a thin film, which will be very useful if the joints need to be separated in the future.
We insert the assembled pipe into the outlet and into the fastening clamps. Tighten the clamps with screws. It is important not to over tighten them. In the street, the screw and nut are exposed to atmospheric precipitation and if they are tightened to the limit, it will be impossible to unscrew the rusty screw in the future. It is better to drop a little silicone into the nut to create a protective film.
Having done all the above work, I got a neat pipe that comes out a little higher than the roof. The main problem, the unpleasant smell that arose during the operation of the sewer, disappeared completely.
To perform this kind of work, contact professionals or study all the subtleties until the moment when wrong actions will lead you to unpleasant consequences.
