Leaking Radiators at Bottom - DIY Repair or Hire a Professional?

Question

Hello,

Yesterday I noticed that water is dripping from two radiators from below, it is strange that suddenly from two of them, because I did not start the heating ...

He adds photos of leaking elements, can you suggest whether you can do something yourself here or will you need a professional?

Regards!

You need to recognize whether:
1. Leaking seals of ball valve knobs - the ones with notches for a screwdriver?
2. Leaking fittings connecting the radiator with the valve assembly? The right photo shows that the spacing of the radiator connections does not match the spacing of the flare nuts.
3. The radiator itself is leaking (because, for example, it has rusty). Suspect is a rust stain in the upper left corner of the second photo.
4. Water (moisture) in the air condenses on a cold radiator and flows down under its own weight.
Wipe dry and watch where the water first appears.
You also need to check the pressure in the central heating installation. There should be a pressure gauge on the boiler.

This is called the radiator connection kit. when a specialist comes, tell him to mount a set in which the screws are plugged with plugs. Of course, you need an angular set.

It depends on your skills. These valves need to be replaced. To do this, drain the water from the system.

Thank you for your answer, after reading it I made sure that a professional will be necessary ;)

Unfortunately, it is leaking through the screws that allow you to disassemble the radiator without draining the water in the system - I do not know what it is called professionally.

So from what I found out, it will be necessary to drain the water from the entire system and replace them.

Close other radiators so as not to drain water from them. But it may turn out that they will also be liquid after moving off.

Thanks a lot for the advice!

And could anyone say how much such an attraction will cost me? Drain water from entire system and replace? More or less, because I don't know what to expect. And the specialist who will take care of it returns from vacation next week

And I don't know if I should be nervous anymore

Well, no exaggeration. There is not much work to do. There is nothing to be nervous about.

I think that he will take a hundred (maybe 150, more should not be) counting the cost of travel and an hour of work, including draining the water and flooding the system again.
Asia, you do not need a specialist for this. Two keys, some Teflon tape and it's done. Ask some kumaty friend and spend the money on, for example, a new blouse

jack63 · Answer

Why Teflon Tape? There are screw connections.
