How to deal with water seepage problems in PVC pipes

The best way to deal with any problem is to find out the cause of the problem. This will help prevent it later, and it can also be dealt with from the source, so that it can achieve twice the result with half the effort, once and for all, otherwise it may be twice the result with half the effort and lead to a resurgence. Does not help

Today, I will mainly talk about the water seepage problem of PVC pipes. Now I will explain from the following two aspects: one is the various reasons that cause the water leakage of the PVC pipe; the other is how to deal with the water leakage of the PVC pipe;

1. Reasons for water leakage of PVC pipes; PVC pipes are mainly used for non-pressure conditions, mostly for intermittent water flow. Generally, the water leakage will not be too serious. As long as it is not buried and concealed, most of them are better to deal with; in the analysis of the reasons, it is actually at the same time Also talked about the precautions about it;

1. The problem of PVC glue; the main function of PVC glue is to weld PVC pipes. If there is a problem, there will undoubtedly be a water leakage problem; the main manifestation is that the glue expires and fails; generally it is almost transparent under normal conditions Sticky colloids may turn yellow outside the shelf life. After opening, they are more likely to deteriorate and turn yellow. In these two cases, it is best not to use glue;

2. The construction of PVC glue is not standardized; the standard method is: the bonding object is of the same material, the overlapping surface of the bonding object must be cleaned in place, and there must be no oil, mud, water marks, etc., keep dry and clean; the overlapping surface of the bonding object Apply evenly to the PVC glue, and then let it stand for about one minute (adjust the rest time appropriately according to the temperature), and then connect the two closely. During continuous operation, try not to apply force to the welded part, and it will temporarily cure for about After five minutes, the final setting is normal after 24 hours (the adhesive setting has a great relationship with the temperature);

3. Damage caused by external force; including artificially caused by external force and irregular pipeline construction; the former, such as external impact, impact, etc., and the latter, such as the PVC pipe is not fixed in place, and the joint is damaged by long-term force;

4. The acceptance inspection link is not in place; when it is done, the water inspection test is carried out. In this link, the construction personnel will generally dismiss it, thinking that the construction is simple and unwilling to take the time to do it; the water inspection is also a self-inspection process. If there is a problem, Generally, it can be checked; such as whether the inspection port is tightened, whether the glue is leaked, whether the material is damaged, etc.;

2. How to deal with the leakage of PVC pipes; the above is the cause of the leakage, the following is how to deal with the problems caused by various reasons; the treatment surface must be kept clean and there is no water mark during treatment;

1. Glue injection method: For small trachoma, gaps and cracks; generally use PVC pipe powder with PVC glue; use a saw blade to saw the PVC pipe to get fine powder, stir with PVC glue, and then inject the problematic point. If the problem is larger, it can be used with a hair dryer to speed up the solidification speed;

2. Patching method: suitable for long and larger problem points; cut a section of PVC pipe of the same pipe diameter, which is slightly longer than the problem point, and split into two halves, the inner wall and the outer pipe wall of the problem point (Equal area) Apply PVC glue, let it stand, close it, and then tie it up;

3. Cut-off method; for the problem point, cut off the two ends directly, and connect the pipes at both ends with the corresponding direct fittings; this usually requires a professional master to deal with it, which is somewhat difficult;

4. Other miscellaneous methods; such as transparent tape processing, waterproof tape processing, glass glue processing, plugging king processing, and even universal glue processing, etc.; some of these have some effects;

Here is a direct way to deal with various problems. If the hidden dangers are still there, they must be dealt with in time, otherwise similar problems may occur again; for example, if the elevator is not installed in place, it leads to the connection. Due to long-term stress, the elevator problem must be solved together.
