How to check the water meter at home?

The installation of a water meter makes it possible to save money, because you pay for consumed water, and not for mythical standards, which, it is a sin to conceal, are greatly overstated. But all this is true only if the device is functional. If the operation of the device is broken, then, perhaps, he considers water consumption by overvaluation. Let's talk about how to check the water meter at home.

Reasons for water meter breakdowns:

• Natural wear. The technical documentation indicates the working life of the water meter and the time at which it is necessary to take the device for verification. If you do not do this, the device may display incorrect data on water consumption.
• Rigid water. Over time, parts are covered with lime scale, which makes the work of the water meter incorrect.

How to check the water meter at home?

If you suspect that water accounting is not done correctly, you can proceed in two ways:

• Call the wizard to dismantle the device. After that, you will have to take the water meter to check in the branch of the water canal. In this case, you will spend not only time, but money. Installation and dismantling of the accounting device are paid services. Add transportation costs here and think: is it not easier to purchase a new device?
• Self check.

Each of these methods has its advantages and disadvantages. The call of the wizard is associated with additional costs, but it will issue a document indicating that the meter is working properly. The self-test of the device is not valid and can only be carried out for complacency.

Test by a specialist without disassembling the

This is a very convenient method, especially if the time is right for the device to be sent for verification. To call a specialist at home it is desirable not to wait until the end of the verification period, but to write an application to the metrological service. At the specified time, the master will come to your house with the appropriate equipment( a pouring installation-flowmeter) and perform the check according to the following algorithm:

1. Mounting of the measuring device to the shower hose opening.
2. Preparing weights and containers for measuring water consumption.
3. Checking the water meter: its wheel does not rotate if all the valves are closed.
4. Fixing the initial parameters of the device.
5. Set of water in a container with subsequent fixation of the instrument. This test is performed using cold and hot water.
6. Production of necessary calculations, derivation of the average error of the water meter.

Important! The procedure should be performed several times at different head. The normative error percentage ranges from 2-10%.If the error in the calculation is within the specified range, the instrument is OK.With a larger error value, the counter must be replaced.

Assurance of the result

Upon completion of the check, the master issues an act to the owner stating that the device is working properly. The document must be presented to the management company. You can not miss the time of the test. Otherwise, the management company can show you the water bill for the notorious average data.

Pros of this check:

• Affordable cost. In any case, it will cost much less than a complete dismantling of the device.
• If the house is an old pipeline, it will not be damaged. Dismantling the meter is no small test for old pipes.
• Save time, but at the same time, strength and nerves.

Important! Less is a rather approximate diagnosis. It is possible that some parts of the meter are worn out, and soon the breakdown will fully manifest itself. In this case, you have to pay for checking the old one, and for buying a new meter.

How to check the water meter at home by yourself?

In principle, this can be done, but such a verification will not be valid. It is advisable, if the verification period has not yet come out, but you have crept into suspicion that the device is "lying."To check, prepare 2 measuring buckets: 10 and 25 liters.

Important! If the metrologists check the correctness of the meter's operation under different headings of water, then we will do the same.

Operate according to this algorithm:

1. Record the water meter readings for cold and hot water.
2. Start the water in a thin trickle and collect a ten-liter bucket. Re-lock the new instrument reading.
3. Using 25 liter containers, collect 1000 liters of water at an average head. Dial continuously, you do not need to close the tap. It is possible that you will need an assistant. Have typed? Now write down the readings of the device again.
4. It remains to spend 1000 liters, or, as people say, "cube".Act on the same principle as in the case of 1000 liters, only now turn on the tap completely. Record the indicators again.

So, you have used up 1110 liters of water. It remains to determine, by simple calculations, what the flow rate was recorded by the device. If the error is in the range from 2 to 10, then the device can be used.

Important! If the water meter is working correctly, then with a small head, it does not count the liters. With an average head, the count is correct, and when strong, he exaggerates the reading a little.

Now you know how to check water meters at home. The following information is for those who passed the water meter in check. No payment can be made according to the regulations. While the water meter is off, you pay for the average water consumption for the last 3 months. If you want to impose something else - it's illegal.
