Many families now choose to install floor heating when decorating. Although the floor heating can bring warmth to the cold winter, there are also many hidden dangers, such as the rupture of the floor heating pipe. What should we do if the ground heating pipe breaks and leaks? Today, I will give you a detailed introduction. Let's see how to repair the broken ground heating pipe? And the repair method of ground heating pipe rupture.
For owners who do not know how to decorate, in case of ground heating pipe rupture and water leakage, they can directly find professionals from the ground heating company for troubleshooting, and can quickly repair.
For owners who know about decoration, they can also repair by themselves. The heating valve must be closed in time, then the valve that controls the water leakage of the water distributor must be closed, and then the air release valve of the water distributor must be opened to remove the pressure inside, so as not to cause too much loss.
First, conduct a pressure test to check whether the floor heating is leaking. * The way is to do a pressure test again. The pressure test must be carried out when the floor heating is installed: close the main valve of the floor heating, press the floor heating with a manual press, and wait for half an hour when pressing the weight. If the pressure can remain unchanged, it means that the heating pipe does not leak water. If there is water leakage, the leakage will be obvious, and the pressure will be difficult to maintain for a long time.
The broken ground heating pipe needs to be repaired by hot melting. Before hot melting, the pipe at the leakage point shall be cut vertically with a professional pipe cutter. The notch must be smooth, and the burr shall be removed before hot melting.
Before the hot melting of the floor heating pipe, the inner and outer walls of the floor heating pipe shall be wiped clean with a dry cloth.
Use the pipe fittings with the same size and brand as the damaged pipe, or the pipe fittings whose quality is worried about the damaged pipe, and equip the hot-melt machine, and then power on the heating.
First use a soft pencil, and then use a hard pencil to draw a line at the hot melt end of the pipe according to the required length.
After heating to the specified time, quickly remove the pipe and pipe fittings from the heating sleeve and heating head at the same time, and quickly insert the pipe into the specified depth of the pipe fittings without rotation, so as to form a uniform flange at the joint, and correct the hot-melt joint, but do not rotate. The angle to keep the fitting and pipe.
After reaching the specified time, carry out pressure test, and use it without pressure relief. The hot melting of the floor heating pipe requires some experience and technology. If it is not properly operated, all previous efforts may be wasted.
Because the installation of the floor heating pipe is deeply buried underground, if the decoration has been completed and the floor tile or floor has been made, it is difficult to judge the damage point and repair it after the damage occurs in the later use. What is the repair method for the broken ground heating pipe? Generally, there are three methods:
Quick coupling
This method is mainly to use two copper pipes to connect the damaged pipes directly, which is convenient and quick to repair. However, it should be noted that, in principle, this method is not advisable for the use of pex materials for floor heating pipes. Because water leakage will occur due to corrosion and uneven heating if buried underground for a long time, it may be OK in the early stage of connection, but it cannot be guaranteed later, so be careful!
Hot-melt joint
This method is to fuse and connect the damaged ground heating pipes at both ends with heated pipes. It is more complicated than * kinds *, so it needs some experience and technology. Ensure that the pipe orifices of the ground heating pipes at both ends are smooth, and the inner wall of the pipes is clean and free of dirt. In addition, the fitting of the joint must be consistent with the original fitting size, and the quality must be the same and guaranteed. Don't rotate the pipe when connecting, just stick it and keep the original angle.
Replace the circulating circuit
What we mean here is to replace the circuit that damaged the pipeline. There is no doubt that this method is * guaranteed, but the increased budget cost cannot be avoided! In addition, it should be noted that the replacement needs to be carried out before the construction of the ground filling layer. If the ground filling layer has been completed, it is not convenient to carry out replacement construction.
