Water level

How many times have we been told that school knowledge will come in handy sooner or later? Of course not all of them, but sometimes it turns out to be the purest truth. When you need to symmetrically nail shelves or draw a horizontal line on the wall , it will be difficult to do this without a level. Water construction level can be easily found in any construction shop, and to make it is also not so difficult. It suffices to recall the laws of physics on combined vessels.

Principle of operation of the water level

You just need to find a transparent hollow hose and fill it with liquid. Next, we'll look in detail at how to build and use the water level:

  1. A hollow flexible tube filled with water just from the tap would be wrong. This will provoke the ingress of air bubbles, which will lead to inaccurate measurement. You need to prepare a bucket of tinted water. Quite logical question arises, the better to paint the water in the water level. In fact, it can be absolutely any coloring matter from children's paints to potassium permanganate. Also, the answer to the question, the better to paint the water in the water level, the food color may well become.
  2. Next, we dip one end of the hose into the bucket, the second we lower it down and pull the water up so that it completely fills the tube. We pour it out until there is not a single bubble in the tube. Then clamp the end of the tube with your finger. The second end is also clamped with a finger and pulled out of the bucket. We lift the two ends and check our device: if the water is on the same level, everything is done correctly.
  3. The accuracy of the water level depends entirely on the correctness of the manufacture. If there is no air inside, the tube is not twisted - everything will be measured correctly.

Application of water building level

To make two marks at the same height at different ends of the wall, you need to work in pairs. First you apply one end and draw a mark. We hold the end of the tube in place and carefully transfer the second part. Be sure to close the ends of the tube with your fingers in order to preserve the principle of the system. In the finished purchase levels there are special flasks on the ends, where the marks and scale are already marked. This simplifies the work at times. It is enough simply to raise or lower it until the water at both ends is at the same level. For a homemade water level, simply mark the mark with a marker. When you fill the water with a ready level, it is important that it is a liquid at room temperature. Do not unscrew the lids of the flasks, since this completely violates the principle of the operation of the communicating vessels.

After you have made two notes, they need to be combined in one line. For this purpose it is convenient to use a colored thread. You fix the ends on two marks, a little pulls the thread, and it hits the wall, leaving a trail. The same method is used with a thread. It's a good idea to double-check the work with a bubble level, if you used

own-made level.

If you need to transfer the line to the opposite wall or to another room, the principle of operation remains the same. Here it is necessary to take a hose more authentic, and for each following district we again take the first mark. This will make it possible to avoid inaccuracy and inaccuracy in the application of control lines. When you have to work alone, one end of the hose is fixed, and the second is carried to the desired distance. It is enough to put the first control marks on each wall, starting from one common, and then move on to the others. Always make sure that the hose is not twisted, there are no kinks, and lay flat on the floor.
