Common causes of bathroom leaks, and ways to find the leak point

Downstairs run up and say the bathroom leaks this kind of thing happens in life a lot, when the bathroom leaks whether for themselves or downstairs are inconvenient, this time need to deal with in a timely manner, the bathroom leaks to the downstairs how to do, together with the reasons for health leaks and how can find out the leak point

A, plumbing leaks (hidden pipe leaks)


1, the cause of pipe leaks


Pipe leakage is one of the main reasons for water leakage in the bathroom, pipe leakage is also divided into inlet pipe leakage, drain leakage.


① Intake pipe leakage


All the pipes connected to the municipal water supply network belong to the inlet pipe. For example, if there are floor heating pipes, cold water pipes, hot water pipes, the water pressure standard of the inlet pipe should be not less than 0.16 MPa. Therefore, once a leak occurs somewhere in the inlet pipe, there will be 16 kg of pressure continuously discharged from the seepage. Therefore, if you want to determine whether the inlet pipe is leaking, you must look at the water leakage watermark situation, such as today look at a small point, tomorrow look at the size of a bowl, and then the day after tomorrow look at become larger, then this is the inlet pipe leakage; In addition, if there is a small amount of water in the sink, shower, basin triangle valve position, wipe clean, soon, then there will also be inlet pipe leakage; the real reason is the pressure of 16 kg constantly squeezing water outward leads to.


② drainage pipe leakage


Drainage pipe generally refers to the water pipe and sewage pipe wall in the bathroom, the water pipe wall in the bathroom, the floor drain pipe, the water pipe wall in the washing machine has a rupture, the drainage pipe connection has fallen off off and other reasons caused by the leakage. General drain leakage is mainly caused by the quality of the pipe or floor drain, bathroom, pipe connection is not standardized, installation did not do a good job of sealing and other reasons. The general performance is leaking when using water, not leaking when not using water.


③Leakage in the main pipe


If the home regardless of the inlet pipe, drainage pipe, waterproof layer are tested no problem, then be sure to see whether the main water pipe leaks, if found that the main water pipe leaks, you can find a professional master repair.


④Leakage of water separating pipe


If you find water leaking from the top of the packing riser, it is likely to be leaking from the upper layer, or it may be leaking from the upper layer, and then the water seeps down the pipe. If you find that water is leaking from the bottom of the packing riser, it is likely that water is leaking from the upper layer down, or it is possible that water is leaking from your own home.


2、Pipe leak detection method


①, to the pipeline to do the pressure test, do pressure test must have to play 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.


②: After confirming that there is indeed a problem with good plumbing. Through drawings, experience or the use of auxiliary tools pipeline 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.

③: to the pipeline on the air pressure, the normal situation can play 8 ~ 10 kg pressure, and then use the professional pqwt pipeline leak detector equipment, along the location of the pipeline for the detection of row by row, the road above the pipeline placed sensors, placed step by step according to the length of the pace, step by step listening, the closer to the leak, the stronger the signal, the farther away from the leak the weaker the signal, by comparing the signal between different points The purpose of detecting leaks by comparing the signal strengths and weaknesses between different points


B. Leakage in the waterproofing layer of the bathroom


①What is the waterproof layer?


As the name suggests, the waterproof layer is a layer of material set up to prevent water from seeping into the ground, walls and other locations. Waterproof layer rupture leads to water leakage, as shown in the figure below.


②Common causes of broken waterproofing


The first point:waterproofing layer is not really done well, such as before construction did not do a good job of grassroots treatment, or that the waterproofing materials used are inferior materials, as well as the use of non-standard products lead to late waterproofing layer rupture.


The second point:waterproofing layer is done, due to cross-construction led to the original waterproofing layer was accidentally destroyed by the construction staff.


The third point: building settlement leads to damage to the waterproof layer, generally this situation is relatively rare.

Use pqwt waterproofing detector, the working principle of the instrument: through the wall, ground, roof seepage of water as a medium, the use of waterproofing detector to detect the strength of the conductivity of the seepage area, when close to the leak point, the instrument interface value increases, the beeping sound to strengthen, thus accurately determine the location of water leakage. The equipment is mainly used in houses, walls, floors and other water leakage can effectively provide a basis for waterproofing work to carry out the discriminatory.
