To date, local sewage in the house or cottage is not considered a luxury. The owners have the right to choose a septic tank at its discretion. To get drains into it lay the pipeline outside. Uninterrupted operation of the system can be ensured by insulating the sewer pipe. Getting started, it is important to familiarize yourself with the advice of specialists, who give a general idea of how to insulate the sewer pipe correctly.
The article does not refer to sewer pipes laid in heated premises or below the level of soil freezing. We will tell about those cases when we cannot do without insulation. In the apartment, pipe insulation helps to improve noise insulation.
Defrosting of sewer pipes
Freezing pipes occurs quite often. Especially the problem is familiar to residents of houses with local sewage.
Ice in the pipe
Some sources It is believed that the insulation of the sewer pipe in the house is not necessary, since the drains, moving along the pipe, have room temperature. In addition, the fluid is constantly moving in the pipes, draining into the septic tank. But freezing happens and eliminate the damage will not be easy. In some cases, repairs are laid up to heat, and the house remains without sewage.
It’s not comfortable in such a toilet room
A visit to the restroom on the street has some advantages:
However, this prospect of “saving” will not please anyone, therefore, in order to minimize the risk of such situations, it is better to deal with the insulation of the system in advance.
The three most popular methods of insulation of the sewerage system:
Different insulation materials can be used to insulate outdoor sewers.
Thermal insulation of sewage with mineral wool
Material refers to the classic version. But in the process of its use is not profitable for economic reasons. When using mineral wool, an additional layer of waterproofing is needed, since the material is hygroscopic and loses its main function when wetted.
Polyurethane shell for pipe insulation
Foam shells for pipe insulation
The material should be used for outdoor insulation, as it does not tolerate moisture testing. It is produced in the form of cut along the cylinder, with a notch for pipes. The fastening of the cylinder occurs due to locks located at the edges. The material is extremely comfortable to work with, perfectly retains heat and is inexpensive.
Polyurethane foam insulation
Easy to use material, which is produced in the form of pipes. If necessary, it is put on the desired area, pre-cutting the material. Place the cut stick together with adhesive tape.
There are also several ways to insulate pipes in the ground.
Insulation with Penoisol
This insulation is produced as a liquid which when solidified forms a dense shell that prevents the pipe from freezing.
Among the shortcomings of the material: in the process, you must use special equipment. Therefore, its use for warming in a private house will be expensive.
Heating cable plus thermal insulation
Modern pipe insulation method is a heating cable, which is laid on top of the pipe or inside it. In the course of work, stacking should be carried out in a protective channel.
By choosing this method, you can lay the pipe to a depth of less than half a meter.
The disadvantage of the method is the dependence of the system on electricity. When you turn off the electric heating, it stops working.
It should be noted that there is a normal type of cable and self-regulating.
It is better to buy a more expensive version of the heating cable, which will pay off later by saving energy.
The most popular method for insulating a sewage pipe in the ground is its location at a depth below the soil freezing level, where the temperature remains positive and does not allow the pipe to freeze. This method does not require special insulation.
Among the shortcomings of this method, it is necessary to single out the lack of possibility of repairing blockages or other pipe failures. It will be necessary to break the system, which will be very problematic in the winter.
Insulation of sewage pipes on the street
The most suitable option for insulation sewer pipe on the street in the region with strong frosts is a combined method. If the winters do not have a low temperature, you can give preference to insulation insulation material without the use of heating cable.
Warming of the sewer pipe is not an obligatory, but desirable measure, during which you will need a bit of money and patience. As a result, the owners will be protected from unexpected surprises in the midst of frost.
