Any equipment that is located in a residential building must comply with all safety requirements. Through its work, it should in no way cast doubt on the preservation of health, which is true even if any malfunctions arise. Whatever the device, it must be equipped with special elements that can negate the risk of harm to human health. Among other things, these parts are designed to minimize the likelihood of damage to the device in the event of all kinds of malfunctions. One of such parts for water heating equipment is a pressure relief valve. The main purpose of this element is to rid the boiler of excess pressure.
Need to use
The element described above must be present on each model of the water heater, because in the absence of this spare part, the water heating equipment will not function properly, and subsequently the owner of the device may be faced with the need for expensive repairs. This is easily avoided by having an important element that must be in place.
The principle of operation of the check valve
If you are interested in a pressure relief valve with pressure control, then you should familiarize yourself with the principle of its operation, which is not complicated. In appearance, this element can be compared with a plumbing tee, but the design features of these elements are significantly different. In the area where water is supplied, a locking mechanism is installed, due to which the liquid can move only in one direction, entering the heater's tank. The operation of this element is extremely simple, but very productive. At the moment of reaching approximately the same pressure, the above-mentioned locking device is activated, which eliminates the possibility of the return of liquid.
Leak Solution

If the pressure at some point exceeds the critical value, then the protective function will begin to operate. It is worth mentioning that the lateral branch functions according to the same principle, however, as a difference, impressive pressure leads to a weakening of the spring and a decrease in pressure in the tank, which is filled with hot water. In some cases, these phenomena cause an impressive leak from the opening of the device. You will notice how water begins to drip. Experts say that although this phenomenon is normal, because it is for this that the device was created, it is still possible to solve this problem. Some owners are not even worried about this. If you are not satisfied with the puddles that appear on the floor, which are formed due to a leak, then you can install a hose, one end of which connects to the outlet of the valve, while the other to the sewage system. If you use a pressure relief valve with pressure control, and during the operation of the equipment a leak has formed that made you install the hose, then you can improve the aesthetic characteristics of the room. To do this, the drain is provided with a pipe or a hidden hose, which will improve the appearance of the equipment installed in the house.
Valve installation technology
A pressure-controlled safety valve is usually sold with water-heating equipment. That is why the installation of these elements is carried out in parallel. This does not always happen, sometimes the installation of water-heating equipment is carried out without using the described element intended for protection. In this case, experts recommend filling the gap by purchasing a spare part separately.
Methodology
Installation work does not imply any particular difficulties, but for this the master still must have some experience and knowledge. If a person does not possess them, then as an optimal solution there will be an option that involves turning to specialists for help. They will install according to all existing rules.
If you will install a hydraulic pressure relief valve with pressure control yourself, you should remember that the element is fixed after the shut-off valve. It must be placed under the tank, leaving the drain hole free. After carrying out the work, you must make sure that the equipment is functioning properly. Many manufacturers produce the described devices with the ability to test. Implementation of the check on their own is real, since the technique in most cases is spelled out in the device instructions. To check the valve's functionality, it will be necessary to turn the handle to the side. It is important to determine the direction of movement by reading the instruction manual of the device. As a result, water should leak. Such checks need to be carried out from time to time, so that in case of breakdowns you have the opportunity to detect them in time.
Wizard tip
It should be noted that the pressure-controlled safety valve for the compressor may have a different device. It is best to ask about the operational features of the master who will be engaged in the installation. If you intend to carry out these works yourself, then you need to familiarize yourself with the instructions, in which all the nuances are spelled out accurately. Thus, when it comes to equipment of the Ariston brand, the models of this manufacturer do not provide for the discharge of water from the boiler. To implement this manipulation, it is necessary to additionally mount a special valve in the form of a tee. A number of device settings can be adjusted, but professionals do not recommend doing this yourself if you do not have the proper experience in this area.
Possible problems with valve operation and solutions
The pressure relief valve for the water heater may not work properly during operation. In this case, you should begin to identify possible causes that contribute to this. Initially, you should check all the elements of the equipment, as any spare part may break and become worthless. It is worth remembering that safety valves, thermostats and heating components are most susceptible to breakdowns, they should be checked first.
Recommendations for work
If the system uses a safety valve with adjustable water pressure, it is associated with the above elements. This indicates that there may be problems with spare parts that work in pairs. Owners of the equipment note that the check valve has an impressive cost, so if it is not possible to repair a used element, you can buy a new one. To do this, you need to know the model of the device, as well as the working pressure with which it operates. This information is contained in the user manual, sometimes it can be found on the device.
Another problem can be dirt and scale, which interfere with the proper operation of valves and water heaters. The solution to this problem may be to equip the feed pipe with filters. If the system operates at too high cold water pressure, the valve may leak during operation, this is true even if the installation was carried out in accordance with all the rules. To solve this problem, you can purchase a gearbox with the desired characteristics.
Additional issues
If a safety valve with pressure adjustment with your own hands has been installed, then after some time of use it can wear out, as a result, the element loses its user characteristics. Spare parts in this case can not cope with the solution of their problems one hundred percent. You must be prepared for the fact that the valve requires the periodic replacement of a new part. At the same time, it is not recommended to save, as this can cause unplanned costs for the purchase of a working device.
V205 Valve Specifications
If you decide to purchase an air pressure relief valve with pressure control, you may prefer the above model. This element is used to automatically protect the device from unacceptably impressive pressure. This part is made in Italy and has earned popularity among modern users. The element has the ability, expressed in manual pressure relief. The material used is nickel-plated brass. If this is a V206 model, then there is no manual reset option. The material is brass, which is not coated with a protective layer during the manufacturing process.
Operating temperature can vary from -25 to +180 degrees Celsius. Connection can be made using a sleeve or internal thread.
In the market of modern materials, you can also find a pressure relief valve UV-55105, which has an affordable cost and a long service life. You may prefer it for equipment.
