To make the living room look beautiful, we usually choose to install water pipes in the wall when decorating. However, once water pipe leakage and burst occur, it will bring irreparable consequences. Perhaps some consumers have already suffered deeply from this annoying "wound".

The economic function of water pipes is viewed from a long-term perspective, so it is necessary to think comprehensively. First of all, The funds for procurement, followed by the funds for regular maintenance. Due to the long service life, it is recommended that when purchasing water pipes, we must choose high-quality products, although The purchase will be slightly more expensive, but the protection funds in the future can be greatly reduced.

The factors that form this might come from the following aspects: The plastic pipes used are not qualified products themselves. There are some substandard and shoddy products in the market, such as those that fail to meet the requirements for compressive strength and thermal expansion coefficient. Coupled with non-standard construction, there are bound to be problems in the project.

Secondly, it is determined by the physical and chemical properties of the plastic pipe itself. Since the plastic pipe is connected with metal at the bend, the plastic pipe and the metal are not welded by electric welding or screwed together, but bonded by a special adhesive. When there is a large temperature difference, such as a sudden drop in temperature, the coefficients of thermal expansion between plastic and metal are different, and the glue is prone to cracking, which then causes the water pipe to burst.

Third, the issue of aging of plastic water pipes. Because plastics contain "plasticizers", they will escape over time, causing the plastics to harden and become brittle. Sunlight can also cause plastics to age, and ozone in the atmosphere is also harmful to plastics. Aged plastic pipes are prone to burst under the impact of water pressure and the effect of water hammer.

In the past, the pipes mainly used for water supply were cast iron pipes. Outdoors, sand-cast iron pipes are mainly used, while indoors, galvanized cast iron pipes are used, which can be further classified into cold-cast iron pipes(electricity)There are two types: galvanizing and hot-dip galvanizing. Galvanized pipes are used as water pipes. After several years of use, a lot of rust and scale will accumulate inside the pipes. The yellow water flowing out not only pollutes sanitary ware but also contains bacteria that breed on the rough inner walls. The rust causes excessive heavy metal content in the water, seriously endangering human health.

Each one has its own distinct characteristics. To determine which one is needed in the decoration, it is necessary to summarize and think about the situation.
