Sewer pipe repair without dismantling

The sewer system in the apartment or house must operate properly. By conducting periodic inspections and taking preventive measures against breakdowns, trouble-free operation of structural elements can be achieved. But sometimes emergency situations do happen. It is worth knowing how to repair sewer pipes without opening and dismantling.

Necessary tools and materials

To repair damaged sections of the sewage system, it is worth stocking up with the necessary tools:

• paint brush;
• a metal brush or sandpaper;
• hacksaw;
• construction knife.

In addition, it is desirable to have the following materials at hand:

• construction glue;
• cement;
• liquid glass;
• solvent or degreaser;
• bandage or tape made of fabric;
• clamps or wire;
• rubber.

These tools and materials are enough to cover the joint at the leak or repair the burst pipe. For major repairs, it is worth purchasing pipes and fittings.

Causes of damage to sewer pipes

The main types of sewage breakdowns are leaks. Usually they occur at the joints of structural parts, sometimes along the element itself.

Causes of leaks:

• High load on a single part. This usually happens with system blockages. Increased pressure inside the structure leads to damage in the weakest areas. You can restore the system to normal operation by mechanical or chemical cleaning.
• Freezing of structures in winter also leads to malfunction. Often, parts operated on the street are defeated. But accidents also occur inside buildings. Water expands upon freezing. An ice plug is capable of breaking the material of pipes or fittings.
• Parts of poor quality or improper installation of the structure also lead to the destruction of individual elements. It requires the replacement of gaskets or the repair of pipes and fittings.

Depending on the scale of the damage, urgent or major repairs of the sewer system are required.

Urgent pipe repair

Cast iron constructions are often found in the old foundation. Breakdowns in such highways are not uncommon. Replacing a single part in this case is difficult. Leaks in cast-iron pipelines are sealed using sealing means.

Often apply coating of the leak with construction adhesive with cement.

1. Brush remove rust from metal parts.
2. The treatment site is degreased.
3. Apply a layer of construction glue with a brush.
4. Cement is poured on top.

Similarly, several more layers are performed. Then you need to dry the cement-adhesive patch. This method is effective for small leaks. In more serious cases, you should use a different recovery option.

1. Preliminary processing of metal parts.
2. Cement is diluted with water, water glass is added.
3. The resulting solution is impregnated with a bandage.
4. The material wraps the leak in 5-6 layers.
5. The structure on top is treated with silicate glue.

There are several ways to perform urgent repair of plastic pipes without dismantling:

• Using sealants - the dried and fat-free crack is coated with a waterproof agent.
• With the help of special tapes - the damaged place is wrapped with material in 2-3 layers.
• Using rubber and clamps - rubber pad is placed on the site of leakage. On the edges of it fasten with clamps.
• By soldering.

You can stop the leak in a plastic sewer pipe in a more radical way. For small use couplings.

1. A damaged piece of plastic is cut with a hacksaw.
2. The edges of the pipe are cleaned of dirt and degreased.
3. Sandpaper is used to create a rough surface.
4. Glue or sealant is applied to the ends of the elements.
5. Dress the clutch.

Cracks larger than 10 cm are closed using two couplings and a pipe segment. Repair technology is identical to installing one fitting.

Overhaul

If water runs through the joints in a building with plastic sewage, it is not necessary to dismantle the entire system. You can eliminate leaks at the joints of sewer pipes with the help of a major overhaul of the structure. There are the following methods for this:

• Insertion of smaller diameter pipes into existing networks. To do this, do not open the sewer pipe.
• Restoring the integrity of the pipes with a flexible tab from a textile stocking, which is impregnated with epoxy resin. Thus, a new waterproof structure is created inside the old pipelines.

The use of new technologies makes it possible to repair old highways outside and inside the building without excavating trenches and dismantling the sewage system.

Sewerage repair on the upper floors of buildings has some features. Here an air cushion is formed from gases from drains. They are removed from the system through the sewer ventilation pipe. For this reason, damage repair is carried out with careful sealing. Otherwise, the gases from the sewage system will enter the living quarters.

Common mistakes in the repair of the sewer system

The most common errors during installation and repair of the waste structure are the following points:

• During installation, choose the wrong slope of the pipes. This leads to disruptions in the operation of the entire structure. A large angle of inclination promotes the gradual subsidence on the inner surface of parts of solid particles that are not completely washed off by water. Insufficient slope can cause siltation of the pipeline and the formation of plugs.
• Poor sealing of the joints of various parts quickly leads to the need for repairs.
• Often malfunctions result from the lack of revisions and sewer ventilation - they are simply cleaned during repairs in the house.

To restore the sewage system, do not use corrugated pipes instead of siphons. They are faster clogged and harder to clean.

Preventive measures against sewage breakdowns

In order not to have to eliminate breakdowns and malfunctions in the sewer system, it is worthwhile to take preventive measures in advance.

• You need to buy high-quality products with the required technical characteristics.
• When installing individual parts, special attention should be paid to the joints. They need to be well sealed.
• Parts of the waste system that are operated at low temperatures are insulated. Foamed polyethylene or a foam sheath is used here.

A properly mounted waste system made of quality materials can last a long and reliable time. If necessary, you can repair the sewer pipes without opening the structure yourself.
