Ever wonder how the water supply system in your house keeps the water pressure steady despite variations in demand? Presenting the hydroaccumulator, an essential part that keeps your showers cool and your taps running smoothly. However, what precisely is a hydroaccumulator, and why is your water supply system dependent on it? Let’s examine this clever device’s operation.
Consider your home’s water supply system as a system of pipes that supplies water to different fixtures. Water shoots through the pipes to satisfy your demand as soon as you turn on the tap. However, the system experiences a drop in pressure, leading to reduced water flow, if multiple taps are opened simultaneously or if there’s a sudden surge in water usage (like flushing a toilet or running a washing machine). The hydroaccumulator comes to the rescue in this situation.
In spite of variations in demand, the hydroaccumulator acts as a pressure stabilizer to keep the pressure in your water supply system constant. It uses an easy to understand but efficient mechanism to achieve this. There is a pressurized chamber with water and air inside the hydroaccumulator. Potential energy is stored when the water compresses the air as it enters the chamber. The compressed air forces the water out of the chamber as the demand for water drops, keeping the system’s pressure constant.
So why is your water supply system in need of a hydroaccumulator? Imagine this: you’re taking a soothing shower when all of a sudden there’s a dishwashing scene in the kitchen. The drop in pressure without a hydroaccumulator could reduce your relaxing shower to a trickle of water. But when a hydroaccumulator is present, the system easily adjusts to the higher demand, guaranteeing that your shower will continue without interruption.
Hydroaccumulators give your water supply system additional advantages in addition to steady water pressure. They help your water pump last longer by lowering the number of starts and stops, which saves you money on repairs and maintenance. Hydroaccumulators can also optimize energy consumption and minimize water waste, increasing the overall effectiveness of your water supply system.
In summary, the hydroaccumulator is essential to preserving the effectiveness and functionality of the water supply system in your house. This clever gadget makes sure that your showers stay cool and your taps run smoothly by regulating water pressure and reducing demand variations. Thus, the next time you turn on the faucet, stop and honor the hydroaccumulator—the unsung hero that works tirelessly in the background.
In a nutshell, a hydroaccumulator is like a handy backup battery for your water supply system. It helps maintain steady water pressure throughout your home, even when demand fluctuates, like when multiple taps are used simultaneously. Here"s how it works: When the water pump fills the accumulator tank, it compresses air trapped inside. This compressed air acts as a cushion, storing energy that can be released when needed to keep the water pressure consistent. So, if you"ve ever experienced weak water flow or sudden pressure drops, a hydroaccumulator could be the solution. It ensures reliable water flow and reduces strain on your pump, making your water system more efficient and dependable.

How the hydro accumulator is designed and works?
Because a unique rubber gasket called a membrane is located inside hydroaccumulators, these devices are also known as membrane tanks. The vessel is split into two sections by it. Water is present on one side of the diaphragm while air or interstitial gas is present on the other. In addition, the hydraulic tank typically has a water inlet port and an air pressure-reflecting pressure gauge installed.
A hydro tank usually has a rubber diaphragm and a metal body. Furthermore, a filter is installed to eliminate fine contaminants and a spool valve is installed to control the supply-discharge of air.
The pump moves water into the tank and supplies the water supply system. As a result of automation, the hydraulic accumulator’s gas pressure rises. The water supply is cut off and the pump is disconnected by the automatic control system when the value reaches the maximum permitted.
The hydraulic tank’s working principle in the water supply system is depicted in detail in the diagram. Because it is automated, the device has a longer lifespan.
The water in the tank is gradually used up. The automatic control system activates the pump when the pressure drops and reaches the lowest predetermined point. Water is poured into the tank until the pump is turned off, the pressure reaches the desired level, etc.
Why such a storage tank is needed?
When a hydro tank needs to be filled with enough water, that’s when the pump on/off cycle happens. Every time a household member turned on the faucet in the absence of a water storage tank, the pump would turn on. The system’s storage tank’s existence enables:
- significantly increase the service life of the well pump;
- prevent harm from possible hydrostatic shocks in the system;
- to maintain a certain pressure in the system;
- prevent breakdowns of elements of the water supply system and sanitary equipment.
Hydro accumulators are obviously a basic requirement for closed-type water supplies. The following video provides a detailed explanation of the storage tank’s function in the water supply system:
Types of membrane tanks and their features
Hydro tanks come in vertical and horizontal varieties, and their installation locations vary. There’s one more thing to consider. A tiny amount of air may build up in the water-filled portion of the tank over time. To keep the system from experiencing a potentially fatal air lock, this air must be periodically removed. When air builds up at the top of vertical tanks, a special nipple is used to remove it.
It gets a little trickier with horizontal hydro tanks. You will require a ball valve, a sewer drain, and a nipple in order to release the trapped air.
If the capacity of a small hydro tank is less than 100 liters, its owner must remove extra air. For this reason:
- Disconnect the power supply.
- Open the mixer tap.
- Wait until the tank is empty.
- Close the faucet.
- Connect the system to the power supply, so that the tank is filled again.
The water will escape along with the extra air. At minimum once a month, this process ought to be carried out.
Hydro tanks with a red color are intended for hot water supply systems. They are not meant to be used for delivering cold water, even though the rubber diaphragm is fairly sturdy.
Manufacturers provide colorless, blue, and red tanks. The blue devices are meant to be used in systems that supply cold water. The food-grade rubber used to make the membrane in these tanks is safe for human consumption. Red hydro tanks are intended for use in hot water supply and heating systems. Since the rubber used in the membrane of these types of tanks is different, using them for cold water is not advised. Furthermore, blue tanks have a higher operating pressure threshold, up to 8 Bar.
Water typically enters the accumulator from the bottom, and air is released through a nipple at the top, as was previously mentioned. It is important to distinguish between the two threaded connections—usually half-inch or inch—that are present on each device. An automated device for air removal is frequently installed on the upper nipple.
There are instances where the hydro tank receives water from the top of the tank. It is believed that automatic venting is not required in this situation. However, in order to keep sand particles or other impurities out of the system, a filter needs to be maintained.
Kindly take note! A range of hydro tank models, both from domestic and foreign manufacturers, are available to consumers. The length of time that imported devices function flawlessly is greatly shortened because not all of them are compatible with the Russian water supply system. High-quality domestic hydraulic tanks have a longer lifespan, as demonstrated by experience.

| Principle of operation | A hydroaccumulator stores water under pressure in a closed system, utilizing a rubber diaphragm or bladder. As water enters, it compresses the air in the upper chamber, creating pressure. When a tap is opened, the pressurized water is released, maintaining consistent water flow even when the pump is not running. |
| Need in water supply system | A hydroaccumulator ensures steady water pressure throughout the plumbing system, preventing fluctuations caused by varying demand or pump cycling. It reduces pump wear and noise, increases pump efficiency, and provides emergency water reserves during power outages or pump failures. |
A hydroaccumulator is an essential component of a household plumbing system that helps to maintain steady water pressure. It makes sure that water is always available at the right pressure whenever a tap is turned on or a fixture is used by storing pressurized water.
In the absence of a hydroaccumulator, plumbing system water pressure can fluctuate, resulting in problems like poor water flow, uneven shower temperatures, and possible damage to appliances like dishwashers and washing machines. The reason for these variations is that water pressure naturally drops as it passes through pipes, particularly in properties with different elevations or multi-story buildings.
Reducing the frequency of pump operation is one of the main advantages of a hydroaccumulator. When there is little demand for water, as when there are no open taps, the hydroaccumulator keeps the pressure high without requiring the pump to run. In addition to saving energy, this lessens wear and tear on the pump and increases its lifespan.
A hydroaccumulator can be used as a backup water supply in the event of a pump failure or other disruptions to the water supply, in addition to stabilizing the water pressure. It offers a stopgap measure until the problem is fixed by holding a specific amount of pressurized water, guaranteeing continuous water supply for necessary domestic chores.
Overall, a hydroaccumulator’s working principle is quite straightforward but incredibly helpful for keeping a home’s water supply system dependable and effective. Because of its capacity to maintain water pressure, lessen the frequency of pump operations, and offer backup water storage, it is a crucial part of contemporary plumbing systems, improving homeowner comfort, convenience, and functionality.
