What should I do if there is a leak in my home's sewer pipe? How should I fix it?

Whether it's a new house or an old house that has been lived in for decades, a leaky sewer pipe is a real headache that not only makes the bathroom "flooded", but even makes the whole house full of odors. The best way to deal with leaking pipes is actually to carefully identify the leak point after repair, and do a good job of leak prevention measures, the following will explain in detail the method of waterproofing and repairing water pipes.

A, how to repair leaking pipes

Method 1: Repair with glue. If the leak is not very serious, then you can first find the leak point of the downspout, and then plug the gap with a special plugging glue, you can effectively alleviate the leak.

Method two: replace the old pipeline. If the sewer leak is due to more serious cracks or damage, then the glue repair is obviously not practical, although the operation is simple, but the symptoms are not the root cause, the most thorough method is to replace the old pipe with a new pipe, it is recommended to let professionals operate.

1、Block the leak with glue

If there is a slight degree of leakage in the pipe, such as just a trace of water droplets occasionally, then you can use the plugging glue to repair. First of all, you need to carefully observe the pipe and determine the location of the leak, and then evenly apply the plugging glue in the gap, and wait until it is completely dry to effectively alleviate the phenomenon of water seepage.

The operation method is simple and can be completed, but the disadvantage is that the water pipe is, after all, a high frequency of contact with water in the area, so a long time the crack may still appear leakage phenomenon.

2、Old pipe for new pipe

Just said the repair with plugging gel, belongs to an emergency but no symptoms of the method, then want to completely solve the sewer leak, the best and most thorough method than the old tube for a new tube. First, you also need to find the exact leak point, cut off this section of the old pipe, and then connect the new pipe to fix it. This situation is not recommended to carry out their own operations, after all, the operation is more trouble, professionalism is also relatively strong, it is best to ask professional plumbers to repair at home.

B. How to detect water leakage

1、Valve bolt listening method

Buy a listening rod, and then directly near the water valve to listen to the sound of the sound rod leak, if the sound rod does not make a sound, indicating that there is no leak nearby, if the sound rod emits a large leak, indicating that there is a leak nearby, the user can determine the approximate location of the leak through the sound size. This method is clumsy, but the effect is very good.

2、Listen to the sound method, sound vibration method

Sound vibration method refers to the use of water leak detector to listen to the sound of water leakage, according to the size of the sound and sound quality characteristics of the leak to determine the location of the leak.

Sound vibration method operation steps

Step ①: Analyze the possible causes of water leakage through on-site investigation.

Step ②: to do a pressure test to the pipeline, do pressure test must be playing water pressure, and to ensure that each corner valve faucet is in a closed state, close the main valve of the water pipe. It is best to choose the location of the cold water inlet pipe and hot water outlet pipe under the water heater to play pressure.

Step 3: After confirming that there is indeed a problem with the good pipes. Through drawings, experience or the use of auxiliary tools pipe to locate the location of the specific direction of the distribution of the pipeline. It is best to be detailed to which place there is a tee, elbow, hot fusion point, direct and other such places.

Step ④: put air pressure on the pipe, the normal situation can play 8 ~ 10 kg pressure, and then use a professional pipe leak detector, along the location of the pipeline to test one by one to investigate, locate the location of the leak.
