Loud water running sound in baseboard heaters

LiliP

Hello,

I live in a condo ,third floor, my heaters have very loud water running sound when the heat is on , it happens to every heater in every room and it’s not a tickling or banging noise ,it is just like water is flushing rough the pipes ,and there is no water leaking .I don’t have any valve on these heaters ,Please give me some ideas of how can I make the noise go away .Thank you .

More likely air in the baseboards. Is there a bleeder fitting on one end or the other? Could try that...

Or it could be just high velocity... and since you are in a condo with probably no access to the boiler room at all, can't do much about that.

The heaters all work good ,they are hot.

so what Jamie was saying,
do you have your own boiler and basement?
or is the boiler behind a locked door controlled by ???
there's air in there with the hot water,
either because the static pressure is too low, or a poor piping job around the boiler, or ???
can you get to the boiler? and post pictures?
picture of the pressure gage also,

The boiler is controlled by the HOA and I don’t have access to it .
the sound is like when toilets flushing ,water just keeps coming and going …
I found this at the pipe end .not sure if it’s a bleeder.

@LiliP

Yes that's the bleeder. Call maintenance and have them check the water pressure in the boiler and have them bleed the baseboard

LiliP

I released all the air from the pipes by bleeding ,but the water running sound is still happening

Did air come out?

LiliP

Yeah, air came out ,I stopped bleeding till water came out.

Does every unit have their own boiler?
If your unit shares a boiler with other units then the whole system needs to be bled, not just your unit.
The feed valve could also be closed and you made the problem worse. 
Call for maintenance.
