Weak pressure of hot water from the geyser? Solving the problem - Setafi

So you went into the shower and decided after a hard day's work to rinse and refresh your mind and body. But out of nowhere there is a problem - there is no pressure in the geyser, and hot water barely flows. What to do?

Believe me, the problem is not difficult and happens in 8 cases of buying a boiler out of 10. Therefore, now we will tell you why poor water pressure from the gas column occurs and how to fix the problem. And swim in the shower, finally!

What determines the pressure of water in a gas column

In this section, we will consider the most important points that affect the quality of water pressure of any heater (not just gas). It may simply be that the weak pressure of water from the gas column is caused by the device itself, and not by a breakdown:

• Equipment power. To prevent a small pressure of water from appearing in the gas column, it is necessary to buy a device of adequate power. It is better to buy a gas water heater ranging from 8 to 10 kW - this is quite enough for a shower and to wash dishes in the kitchen.
• The presence of dirt and debris in the joints. Any pipe, not only under the liquid, tends to become clogged. If we are talking about a gas apparatus, then the mesh filter is to blame - it collects all unnecessary waste in front of it and does not let it into the system. The result - the pipe becomes clogged, and there is not enough water pressure for the geyser.
• Scale is the main enemy of every device that heats water. In a gas boiler, this function is performed by a copper heat exchanger (coil). How much scale will collect on the pipe depends on the hardness of the water. If your water is as pure as a spring, there should be no problems. Otherwise, this may be the main reason for the weak pressure of hot water from the column.
• Consequences of repair work with the plumbing system. After shutting off the pipes, and then resuming the water supply throughout the house, there is a pressure surge, due to which all the debris falls right under the mixer. The result is that water does not flow well through the gas column. It is worth checking the plumbing, and only then the insides of the boiler.
• Preventive measures. Like all types of boiler heaters, gas heaters need to be regularly checked for scale, debris, burning and other things that are unnecessary for the operation of the device. Everything is removed and the burner works like new. And stagnation in thorough cleaning can bring a small pressure of hot water from the column.

Poor water pressure through the geyser - we clean the blockage with folk remedies

If your column is not working as it used to, most likely a hefty blockage has formed. Many do not know how to fix it, so they simply endure a weak pressure of hot water from the gas column. Of course, it will not always be superfluous to turn to the master. But where to get an extra couple of thousand? That is why we will fix the problem ourselves.

You can flush the gas burner with a limescale remover. If you cannot find one in stores, then there is also a folk alternative - a solution of citric acid. The whole procedure must be carried out with the utmost care so as not to damage the connections of the gas boiler.

How to flush the column from blockages yourself:

1. Preparatory stage: we close the gas supply and water supply, turn off all the wires and drain the remaining liquid through the valve or faucet under hot water.
2. We clean the mesh filter. It is located right at the beginning of the cold water inlet, in front of the gas heater. You can simply rinse it under water or use a lemon solution if there is a lot of limestone.
3. During cleaning, we check the membrane. If there are cracks on it, this may be another factor in the poor pressure of hot water from the geyser. We replace the membrane with a new one through threaded connections. You really don’t need to explain anything: what you see near the membrane, then twist it.
4. We remove the copper coil. If the thread does not lend itself to the pressure of the key, lubricate the problem area with a universal cleaner, oil or other rust remover. After 10-20 minutes, unscrew the heating element.
5. Next, the copper pipe is soaked in a pre-prepared solution: a pack of acid per liter of water. The product is poured into the tube and lasts about 10-12 hours.
6. After we pull out the heat exchanger, rinse it with clean water and put it in place. Check the integrity of the rubber gaskets - you can install new ones if the old ones are worn out. And in general - it is better to insert new ones.
7. We check the water supply by unscrewing the taps.
8. The tightness of all connections can be checked with soap and water: air bubbles will begin to boil in place of the hole. Such a place must be additionally tightened with a wrench or lubricated with silicone sealant.
9. Everything, work is finished! We connect the gas heater and use it!

If the weak pressure of water through the geyser bothers you all the time, the procedure is carried out regularly. And according to the standard - at least once a year. Citric acid is an inexpensive and effective repair option when the pressure of hot water in the geyser is lost due to blockage or scale on the pipes.

Why does water flow poorly through the column - or maybe the problem is not in it?

Not always a weak flow of water can signal a direct breakdown of your heating device. Most often, debris accumulates in front of the mixer and does not allow water to pass through normally. The problem appears on the faucet filter, rubber hose, or other parts of the plumbing system.

To fix the problem, disassemble the parts of the faucet where the fluid passes and remove any debris.

If hot water flows normally in the kitchen, but badly in the bathroom (or vice versa), then the problem is definitely in the faucet filter. It must be removed and washed under running water. If the problem affects you often (or literally every month) - replace the filter more often or wash it.

Also, due to the constant high temperature of the burner, rubber gaskets can break. A warped part will take up part of the pipe space and prevent the water from flowing normally. Locate the breakage and replace the rubber insert.

What rules should be followed so that the water pressure in the gas column is always strong

In order not to constantly run to the store for citric acid or not to wash the spare parts of the boiler, disassembling it into atoms, you should follow the simple rules of operation.

It is better to know the problem in person and not bring it to it, rather than spend money on repair supplies or on a new boiler.

What can and should be done now:

1. Take a bath or shower with a water temperature not exceeding +40 °C. This indicator is also good for the body (not too cold), and excess scale will not form.
2. 45-50 °C is enough for a washstand or dishwashing. The water is comfortable for the hands, and the fat on the plates is already washed off.
3. The washing machine will have a temperature of 45-50 ° C. If things are very dirty, add about +5 ° C.

This temperature was chosen for a reason. This is because lime deposits appear at temperatures up to +80 Celsius. Scale is deposited even on perfectly clean surfaces, and the boiler begins to “sick”.

And to prevent this from happening - watch your household appliances. All the best to you and have a great day!
