After some advice if possible from somebody in the know about home radiators?

Basically last week I came home and spotted a long air bubble in the paint on my bathroom radiator, I gave it a squeeze and as suspected water squirted out.
I turned that rad off so it can't keep leaking.

Then today after spending all day laying a brand new laminate floor I turn round for 2 minutes and I can hear water dripping and splashing on the brand new floor, On closer inspection my front room rad has done the same but has a huge bubble in the paint and was squirting a couple of metres across the room.

So why are my rads splitting? Is it just due to wear and tear and a coincedence that both have popped almost at the same time or do I have bigger problems?

Thanks

Ant..

Don't know how old the system is mate but it could be the system has not been treated with some kind of inhibitor or possibly not flushed after installation. Only takes a year or two to corrode rads with no treatment

Well I'm guessing they are the original radiators from when the house was built in 1992, so 16 years old now. I've never flushed them before and we've been living here for 3.5years now.

it is possibly simply wear and tear on the rads. or it could also be due to when installed they didn't flush the system or debris and its eating its way though the rads.

personally i drain the system, have all the rads off, take them outside and flush them out, then link the pipe work with a long washing machine hose and flush the pipe work, 1 rad gap at a time. then re-fit the rads, put in some system flush for a couple of weeks, then drain it out and clean it again. then re-fill it with decent inhibitor.

some will say the above it 'over the top' and that a power flush will clean it out, but the above is the best approach!

Thanks for the advice.

I just drained the front room rad off to get the water right out of it and the water was coming out thick and black so not clean at all. :(

I wouldnt do a power flush :eek:

Not unless you want all the rads to pop!!!

I would replace rads as necessary, then add chemical cleaner (x400 or x800) for a week, then drain system fill up water only run for a day or so then drain again and stick a couple of litres of sentinel x100 or equiv inhibitor in.....

Should do the trick...

fill the system with sentinel X400 cleaner for a week or so, drain and refill with X100. Black sludge in magnatite and corrodes rads.

The black sludge is called magnetite (as above), the magnetite is actually iron oxide (Rust), the rust has come from the insides of your radiators corroding due to 1) lack of inhibitor in the system
2) Poor system design i.e. pump actually pulling air into system,
increasing corrosion :shake:
3) system not correctly flushed during installation, flux left in system
will again increase corrosion :shake:
4) etc etc etc

I would personally replace all rads, then have the system Power Flushed, and then as part of the flush have a "Magna-Clean" fitted, this is basically a magnetic filter, which will filter out any magnetite in the future, its made by a company called 'ADEY' and can be easilly cleaned out once a year - 5 min job.
Hope this helps mate :smthumbup

P.S. PM me if you want any more advice ;)

No. electrolytic action is the cause of the corrosion, must have been a few bits of copper shavings or a similar anode to cause this action on the steel rads.

I've had a mate whos a plumber to pop round today and take a look.

He says in his opinion all my rads are fed by very thin microbore pipe, they've got kinks in them where they've been bent too much etc and the rads have got so much thick black stuff in them that its caused back pressure and popped the rads.

We removed the 2 rads off the wall and have blanked the pipes for now. He said what was coming out of them is the worst he's ever seen. reckons to get a quote for a complete new system as cleaners and flushes won't work. :(

I'm going to phone a few local companys tommorow and get a profesional opinion and a quote on what needs doing, hopefully they might just say new rads and a flush out, rather than complete new system.

Thanks again guys for your help.
