What is the principle that PPR pipes should be installed short rather than long, straight rather than curved?

In the process of home improvement, when installing water pipes, you will hear from the plumber that the installation of ppr water pipes should be short rather than long, straight rather than curved. What's the point of this sentence?

Short rather than long

First of all, it should be short rather than long. From the perspective of cost, the installation of water pipes should be the most economical line for installation. It is because the pipeline is too long on the one hand, waste, on the other hand, it will also cause unnecessary flow loss. Also, the longer the pipeline, the more joints are required in the entire water system, which increases the risk of welding defects.

From another point of view, the longer the pipeline, the more obvious its water hammer effect will be. Although it is said that in the home improvement waterway, water hammer generally does not cause great damage, but minimizing it as much as possible is helpful to the stable operation of the entire system, at least prolonging the service life of the waterway system.

Should be straight, not curved

Secondly, it should be straight rather than curved. From the perspective of cost, in the waterway, water pipe fittings are actually used in every curved place, that is, elbows, tee fittings, and the prices of these fittings are relatively high. . If there are more straight lines, the relative cost will be lower.

In addition, from the perspective of water flow, due to the bending of the pipeline, the resistance of the water flow will increase to a certain extent, and the speed of the water flow will be reduced to a certain extent, thus affecting the final flow of water and bringing the water experience to a certain extent. bad influence.

The seemingly simple task of installing waterways is actually a lot of mystery. Just like the phrase "short rather than long, straight rather than late", only by fully understanding its meaning can a truly good waterway design be achieved. For every simple job, if we should consider enough details and do it to the extreme, so as to enhance the experience of the end user.
