Funny noise from radiator, Help Please.

Hi,
This morning we started to get a noise that sounds like running water in a radiator in our house. Its just one radiator giving off the noise, can anyone advise what this may be?

Thanks for any help.

airlock? sludge buildup?

try bleeding the radiator and see if that helps

Can i bleed the radiator myself? If so any advice on how i could go about it?

Easy job, thought you need a radiator key, (any DIY store sells them).
If you look at the end of the radiator, at the top, you will see a small square headed screw on one side.
Get a cloth to catch any water and slowly unscrew it, but only until you get a hiss of air, when this stops and you get a a spirt of water tighten it up again. Job done.

I have seen some newer radiators that have a slotted head that you can use a screwdriver on.

Also its best to have the pump of while bleeding the rad.

Thanks, looks like we have one of the newer ones, so will try a screwdriver on it.

Thanks again.

turn your pump to a lower setting,and balance your system ,ie turn some radiators slightly down ,you might also have vents to bleed the system in your loft or cylinder cupboard,also put a cleaner and inhibitor into the header tank for your heating system(the small tank )in addition to venting each radiator.The above should re4move air and sludge,but the inhibitor and cleaner combined is expensive ,but worth it ,every-one should maintain their systems in that way

I have bled the radiator in the bathroom and now none of the heaters upstairs are heating up. Should i bleed all the radiators, or have my wonderous diy skills broke something?

yes bleed them all.. it will save you money!

if they are warm at the bottom, and cold at the top (after the heating has been on for a while), then that is air at the top, and it should be water.

Don't forget to SWITCH THE PUMP OFF, before you bleed otherwise it is possible air could be 'sucked in' to the radiator(s).

Thanks everyone for you help so far.

What is the pump? Does this mean just making sure the heating isnt on whilst bleeding?

The circulation pump. Just turn the heating off before you bleed.

Just turn you system off while you vent the rads, then turn back on.
