Recently, I observed the conditions of some fire hydrants in different locations and felt that there were more or less some issues. I’m posting this here; I’d appreciate it if friends could offer their opinions or suggestions regarding these fire hydrants. In particular, I’m interested in knowing what standards and regulations these opinions or suggestions are based on. For each diagram, those who provide a complete response first will receive high scores as a reward! See images on the floors below

Hidden among the grass baskets, this is barely visible; this one allows one to see above the head; this one is still fairly visible
According to the specification book 01S201 \"Installation of Outdoor Fire Hydrants\", the installation height of this fire hydrant is insufficient, either due to a change in the ground level.
According to the specifications in the 01S201 code \"Installation of Outdoor Fire Hydrants\", the distance from the center of these tall fire hydrant nozzles to the ground exceeds 450 mm, which may make it difficult to connect pipes to them.

According to Article 7.2.6 of the “Technical Code for Fire Water Supply and Fire Hydrant Systems” GB 50974-2014, municipal fire hydrants shall be installed in locations such as sidewalks and green spaces where fire trucks can easily access them. They must not obstruct traffic, and must also comply with the following requirements: 1. The distance between a municipal fire hydrant and the roadside should be no less than 0.5 meters and no more than 2.0 meters； 3 Municipal fire hydrants should be avoided from being installed in locations prone to mechanical impact; if this is unavoidable, collision prevention measures must be taken. In the diagram, the two fire hydrants are one larger than 2.0m and the other smaller than 0.5m, with no collision protection measures.
In my opinion, as long as it does not affect the water flow from the pipe connections, it is better to have fire hydrants that are shorter in height – this is due to considerations related to freezing in winter. In the catalogs, taller fire hydrants are prone to problems such as freezing and cracking during winter, with the exception of areas in the south where there is no snow.
