The gas column allows you to forget about off-season outages and repair work in the highway. You can enjoy a bath or shower all year round if the appliance is working properly. But what if the pressure of hot water is weak? We will tell you why the pressure drops and how to fix it yourself.
Why the bad pressure in the column
Despite the power control on the speaker panel, many users suffer from changes in pressure. Water is either flowing or not, it is becoming impossible to take a normal shower. What is the reason for the differences, can this be fixed? Consider the most common of them.
- The power of the equipment does not meet the requirements. You bought a device whose capacity is not enough to provide the required amount of hot water. It is best to choose a column from 8 to 10 kW.
- System blockage. The water that flows through the main and enters the pipes contains fine debris, pieces of rust, and particles of lime. To trap debris at the column inlet, a strainer is installed. Over time, it becomes clogged, so the elements of the pipeline are periodically cleaned.
- Scale layer. Gas boiler works on the principle of instantaneous water heater. Here, water does not accumulate in the tank, but passes through a heat exchanger, where it is heated by the burner. During heating, potassium and magnesium salts are formed, which settle on the walls of the radiator in the form of limescale. Over time, it grows so much that water seeps with difficulty, so there is little pressure in the tap.
- A matter of technology. During the technical work, the water supply is shut off. After renewal, a water hammer occurs, scale particles in the heat exchanger enter the mixer. This can be seen by opening the tap: the liquid does not flow well.
- Lack of maintenance. Be sure to carry out the prevention of gas equipment. Check the condition of the elements, remove dirt and carry out cleaning. How to clean the gas column, read the previous publication.
- Low pressure. Little depends on the user if there is no pressure in the line. In this case, it is not surprising that there is no pressure. If you want the column to run smoothly, you can turn on the pump in the system. However, this option is more suitable for residents of the private sector.
There can be many reasons. Carefully inspect the instrument to determine one of them.
The pressure is gone: how to fix the malfunction
What can be done at home to restore flow?
Strainer cleaning
The filter is installed at the inlet to the boiler water unit. By holding up trash, it does not allow the system to clog. To clean a part, you need to:
- Shut off gas and water.
- Disconnect the pipe or flexible hose that leads to the assembly.
- Remove the filter and rinse under a stream of water.
- In case of severe dirt, you can use a stiff brush, and also leave the item to soak in a solution of citric acid.
If defective, replace the filter with a new part.
Descaling
We already wrote about effective tools and their application. Recall that it is not recommended to use special substances from scale, they corrode the walls of the copper pipes of the heat exchanger. As a result, even more scum forms on bumps.
Citric acid can also be used to flush radiator pipes.
Blockage control
To eliminate blockage in the pipes will help reverse the flow of water. If your mixer can be installed in the third position, then do this:
- Remove the plug and place a container to collect water under the housing.
- Set the mixer to the third position.
- Unscrew both taps. The flow will start moving in the opposite direction and, possibly, push out the debris. At this point, water will flow from the column.
Mixer Problems
If the blockage penetrates into the mixer parts and the pressure drops, then you need to clean it. Disassemble the device and rinse the rubber hose, filter and other parts with running water.
The reason for poor filing most often lies in the untimely care of the equipment. Therefore, carry out prophylaxis at least once a year.
