Who can use a hydrant?
A hydrant is a device that is brilliant in its simplicity and has contributed to averting the danger of fire on many occasions. It is equipped with a special valve and connector that allows you to attach a hose to draw water from underground sources. As we know, a hydrant is used to draw water and fill fire vehicles with it. These are crucial to the success of the firefighting mission, which is why they must be placed in a visible place that is easy to get to.
However, as it turns out, other users can also use these devices. In this case, you should apply to the commune, which is responsible for their technical condition, to order them to issue technical conditions for water intake from the fire hydrant.
In other words, if we need water for other purposes, for example building a road, modernizing a bridge or watering greenery in the city, such a possibility exists. Of course, this involves fees according to meter data. However, there is no option to use above-ground hydrants for watering the garden and other such purposes.
How to unscrew a hydrant with a hydrant wrench?
It seems easy to connect to external hydrants, but to gain access we need a special key. Let us also remember that depending on the place, different types of hydrants are installed - external and internal. You also need to pay attention to this when using them. Each of them, of course, serves fire-fighting purposes, so in the event of a threat to health and life, you must act quickly.
Operating a hydrant wrench requires some skill. The first step is very important, in which we must precisely place the key on the hydrant valve. This ensures stability both when opening and closing the valve. To lock it, the key usually needs to be turned clockwise.
To open it, of course, you need to unscrew it in the opposite direction. It is extremely important not to put too much force into this operation, because you can damage not only the key, but also the valve. You also need to make sure that the key is matched to the valve - its size and type. Let's also remember about regular maintenance of hydrant keys .
