When turning the central heating on, our two downstairs radiators seem excessively noisy. There's a constant running water sound through them, almost like a tap, yet the upstairs ones are absolutely fine. I've tried bleeding them just to see if it's trapped air, but that's done nothing. They're getting fully hot all over.
Are there any obvious reasons as to why this might be? Not the end of the world if they're working I know, but it's noisy enough to hear over anything else you're doing.
