Loft Overflow leaking

[shaun2312]

Hi guys,
I need some advise if poss - I have an overflow leak and it's from the loft. I went up there and took the lid off the cold water tank to find the water above the overflow pipe.

Any advise on how to stop it filling too much would be great!

Thanks in advance!


Edit: I tried to link 2 video's showing it but was restricted

Hi,

I would just replace the ball valve, but the reason its started doing this is because the washer has warn down.

 

[MrMeek]

just watched the video, isolate the water to the tank, the arm of the ball valve has a brass split pin in take that out and the arm should come out, then bend the arm over your knee ( just a tweak not to much ) then reassemble should work if not try bending it more.

That's your heating F&E tank. level's far too high, just bale some water out and (CAREFULLY) bend the float arm down. the washer looks to be holding ok.

Thanks for the help guys, I have been back up (damn its hard work) and bent the arm over a little so that the float is now fully submerged. One more question about the F&E tank. I havn't taken any water out as there is hardly any room to move let alone safely remove some water up there. will the water drain out at all? Or is removing it up there the only way?

 

[MrMeek]

the F&E tank feeds your radiators if it is a F&E at all that is, if you have a drain valve on a radiator you could let water out that way, but from my point of view just leave it it shouldnt be a problem

It will only remove itself if you have a leak on your heating circuits.
As croppie said, it will be best if you bail the excess water out so you dont have any water coming through ceiling.

Try your best to get a jug and a bucket. Pass the bucket down to another person who can help to minimise spillages.

I recommend to have the F&E tank half full so you have plenty of room for expansion

 

[MrMeek]

or get a hose of some sort and siphon the water out...

You can drain off some water from your system if you have one of these near a radiator.

Put something under it to catch water, or put some hose pipe on the ribbed bit and secure it with a jubilee clip and run it outside, then open up the valve until you have drained off the required water.
