Optimal Pumping Method for 25l Hydrophore Tank with Low Pressure?

Hello, at the outset, I will say that I looked through dozens of posts with topics about hydrophores on the electrode but also on other forums and I did not find an answer to my problem. I have a pump on the plot with a 25l hydrophore tank, which is the main source of water installation in the house. Water is pumped from a deep well. The current set worked perfectly for almost 10 years, a year ago the pump at the hydrophore started to turn on often and the tap water gently splashed - we called our neighbor, a "specialist", who increased the pressure on the tank with a compressor and the problem disappeared. Currently, an identical problem has appeared - the water in the tap has unequal pressure (splashes) and the hydrophore turns on every 2 seconds for 2 seconds of time, earlier, during normal operation, it turned on every minute for a few seconds ... Unfortunately, the neighbor is already dead and I learned what and how the hydrophore works, I wanted to pump up the pressure myself. I read everywhere and even the Lord in the DIY store said that he would inflate this pressure with a simple car pump - of course I did according to the recommendations from the net, i.e. disconnect the pump from the electricity, drain all the water from the water system and pump up the pressure with the taps open. I bought a reasonably good car foot pump - I pumped it for 2 hours in installments, checking how the water was running and it did not work. I found that I needed more powerful equipment, a compressor. So I bought a compressor / car pump supposedly up to 250 PSI (approx. 18 BAR) at the outlet for approx. PLN 100. When I connected it, the pressure gauge of this pump immediately started to show about 10 BAR - I found that the pressure gauge is screwed up, so I started pumping anyway, after 10 seconds of pumping the new compressor burned - smoke, stench and so much from pumping.
Currently, I do not have a better pump or compressor to find out what the pressure in the tank is exactly - since a year ago our neighbor pumped us to about 2 bar, today it can only be smaller. According to the recommendations on the label of this tank, the basic is 1.5 Bar and the maximum is 5 Bar. So I am asking for help from more experienced people:
- can there be something wrong with this tank that I can't pump it up? (So where does this information come from that you can pump up with a manual pump?)
- if, however, it is the fault of the pump, please indicate some specific good compressors for 230V or some mobile 12v or with aku18v up to PLN 200, which would be sufficient for this type of purpose, I prefer to spend more money, but let this equipment serve a little as it should.
- The hydrophore tank is almost 10 years old, so it probably isn't as tight anymore, but is there any way to seal it? I suppose it will be the cheapest to replace it with a new one?

Thanks in advance for any advice / reply.

In your place, it is after such a connection and if the result seemed unbelievable to me, the first one before pumping, I would connect this device to, for example, a wheel in a car to compare the results and just started pumping. If it indicated reasonably well, the pressure was already exceeded by 100% from the maximum. And if the pressure was there, it's no wonder he burnt out.
To the pressure that is needed there, you can easily pump it up with an ordinary car pump (of course efficient).
Maybe the tank is really inoperative, leaking, but in that case where does this pressure come from, even if the indicator is misleading?

Thanks wojtek1234321 for the answer. I bought the compressor only for this purpose and immediately after unpacking it I wanted to pump up the air - I care about time because I am afraid that such frequent operation of the pump will burn out the engine, which is already a greater cost.

A regular car foot pump - I tried a new two-piston (about PLN 60), but I had the impression that I was releasing more air from the tank when connecting / disconnecting the valve than pumping during pumping ... Anyway, 2 hours of torment with this pump and nothing could not. The pressure gauge in this foot pump jumps terribly, so it is even more difficult for me to read a reliable pressure in the tank.

There must be some pressure in the tank, since the water is still flowing as much as it splashes and the pump is still working. I will add, which may be crucial, that for several months this water has been gradually falling weaker and weaker, so it happened gradually - as if the air was just escaping from time to time.

I wonder if I am doing something wrong before pumping, maybe I should unscrew something else from the tank / pump to be able to pump up the pressure? Anyway (even when it turns out that I need to replace the tank) I would like to buy a good quality mobile compressor - someone will recommend something?

and with taps open, pump up the pressure

I wonder what your colleague wanted to get with it? Perhaps such a model of a hydrophore, but in my opinion, you should turn off the nearest water outlet from the tank, in the end you have to introduce air into it, so you should care about introducing as little air as possible, and not - spread it around the installation and release it with a tap ...

As for the compressor - it looks like you pressed the tip to the valve badly - in that case the valve may not work and all the pressure is accumulating in the compressor tube - hence there was actually 10BAR there (these little compressors get so much) - and it burned out. ..

Detailed description, parameters, what is the type of hydrophore, what type of tank (membrane?)?

Ture11 - from what he associates, the air blown into the tank will remain in it regardless of the taps turned off. Air is pumped into the membrane (such as a rubber ball inside the tank). Unscrewing the taps while pumping, from what I read, the task is to reduce the water pressure so that the membrane can be pumped more freely. One of the guides where the scheme is described is a movie on YT - / watch? V = 3RbxUhNC-P8

Regarding the underpressed valve, I think your theory may be right, I had the impression that I was not pumping this tank at all, so in fact there may be a longer valve there, so I would have to hold the end of the pump hose more tightly with my hand. I will certainly verify it, but anyway I need a new pump now And I want to buy a better compressor to also have other things, such as a car, if needed.

wojtek1234321 - Yes, the tank is a membrane type:
Painted hydrophore tank 25l - Model AC-CE 25 GPM
Polgar importer
Max pressure 5 bar
Standard 1.5 bar

The hydrophore is the JY 1000 Omnigen model - year of construction 2008

If, after connecting the end of the hose to the valve, it showed you the pressure on the pressure gauge, this theory is not valid, it had to open the valve.

wojtek1234321 - Maybe I will specify exactly how it was because I probably made a small mistake. The pressure gauge in the car compressor mentioned at the time of connecting the hose to the tank vent did not react because it was still turned off. Only when the compressor was started with the switch - when it started to pump - the pointer immediately jumped to about 10 bars.

In that case, yes, then he pumped it only into his hose. If it was well connected, i.e. there would be air flow to the tank, then immediately after connecting the hose, you would immediately have the pressure on the pressure gauge, regardless of whether the compressor is on or not. This way you just broke the compressor.
I don't know what valve you have there, but it turns out that there is no airflow through it. If it is the same as for a car wheel (it appears from the posts that it is - a suitable pump and compressor), then you have to try to unscrew the valve, clean the valve, install a new valve and then try to "tap down" the pressure. For several years of non-use, everything in the valve may have rusted, stuck and does not work as it should. if this valve is a "car" then the valve from the car wheel will also fit.

I will definitely check this valve carefully, so please help me in choosing a new pump / compressor, which will make this task easier for me and which I will not burn so easily

If you have the valve / valve "tidy" and unobstructed, if you have a good car pump, you can do it too. A few strokes of the leg and the pressure on the pressure gauge will increase "in the eyes".
this is not a large tank, 25 liters, of which the "area" that is still pumped is, say, a third of this tank ...

This is an ordinary valve for a car tire. To check if it is good, just connect a pressure gauge. If it shows pressure, it means that it is blocked. The pressure in such a hydrophore is about 1.5 to 1.7 bar. An ordinary pump will pump up without any problem. the diaphragm, i.e. the rubber bag, is pumping, it can be checked easily. If the valve is unscrewed and the water flies from the valve, the diaphragm needs to be replaced.

Hello, thank you very much for your help, but it turned out that the diaphragm is damaged, water began to flow after pressing the valve. Previously, I completely ruled it out because I was sure that it was enough to pump it up recently - I did not want to press the valve so as not to reduce the pressure more . For this reason, as you write, it was impossible for me to pump up with any pump. I am just ordering a new tank and I am going to buy an ordinary pump without any combination. Thanks again for helping diagnose my problem.
