The flush ball valve does not want to turn.

Hello.
Let me use this topic. I have a water ball valve with a butterfly installed before the cistern. Now, after almost 10 years, it is difficult to turn with a butterfly, and it is almost impossible to turn without pliers. Is there any way to relieve it without disassembling it?

That`s what I was afraid of. When renovating at that time, I relied on the professionalism of the hired workers. They replaced them with valves that turn worse and worse every year and are placed in a very tight shaft.

Photo present.

That is, an exchange. I won`t do it myself, because I would have to close the vertical and for that I need the consent of the cooperative. After removing the butterfly, I don`t know if there is a choke there, it`s hard to tell, I cleaned it a bit but I still don`t know.

Well, no exaggeration, and in the event of a breakdown on Saturday, will you wait until Monday until the cooperative kindly gives its consent?
However, if you don`t know anything, it`s better to call a specialist.

Five-point question: who wrapped the insulating tape so nicely?

They screwed up when replacing the water meters. Our technical department is on duty 24 hours a day, so just call. Thank you for your interest in the topic, I will leave it to the cooperative`s specialists for the summer.

The cooperative is responsible for the installation of the valve. Then it`s your turf. You go to the administration, report it, close the section, exchange it and the competition is over. Or faster, you go to your neighbors, tell them that you need to cut off the water for a few hours, cut it off, hang a card with a phone number on the valve handle, replace it and move on.

Is this some bungling, just for decoration, or just in case it turns out that they did something wrong and it leaks?

I remember something, they had a leak in the screw connection, and I think they managed it that way.

Well, bunglers
The valve needs to be replaced and that`s it. Over time, sediment has built up there and there`s nothing you can do about it.
You simply have to close and open it once a month.

The only thing left is to remember it.

If there is some space there, buy a valve with a longer lever and, as written above, you need to turn the valve on and off once a month.

The funny thing is that before the renovation started, I had exactly such valves. However, the experts decided to replace them, claiming that they would take up less space and the valves could be packed more tightly. And these are the effects I have.

This is not entirely true. The laconic regulations do not specify exactly who owns the valves in front of individual meters for the premises. In most communities or cooperatives it is assumed that the valve belongs to the common part and the responsibility for replacement lies with the administrator or the cooperative. The water meter is supposed to be the property of the tenant, although there are court judgments that the community may adopt a resolution that the meters also belong to the common area and the tenant is responsible for them.
Check the situation in your cooperative and report (if they include valves) the need to replace these valves because you want to replace the battery and you are unable to cut off the water supply to the apartment.

The apartment is a freehold property, so there are probably different rules here too. The fact is that the cooperative replaces water meters every 5 years. They also replace a damaged air vent without any hesitation, and there are several of them. However, I have to ask what it is like with these valves.

The fact that the apartment is owned does not matter much here. If the cooperative replaces water meters every 5 years (legalization), it will probably also replace the valves. I am surprised that when replacing the water meters every 5 years, they did not notice that the valves were not closing. I don`t suspect that they closed entire pipes to replace the water meters because it makes no sense. Well, you already know how old the valves are.
As for the air vents. The entire central heating installation is operated by the cooperative. All you have left are the radiators and you cannot dispose of them as you wish without the consent of the cooperative.

Why close the verticals? It is enough to freeze the pipe 20 cm before and after the valve.
Beautiful tape, galvanized + Cu.

It generally depends on the cooperative. According to the regulations, the manager is responsible for the installation of the valve. Cooperatives often have it written in their regulations that they are responsible for the screw connection at the water meter. My cooperative is responsible for the valve installations. The valves are mine. When the valve broke, they came and put the cap on the pipe and removed the leak.

Don`t you think that closing the vertical for 20 minutes is easier?

I haven`t solved the issue. I`m waiting for the next renovation. Ho ho - then I`ll wait...
