Cracked cold water storage tank

[Tom JE]

Alright chaps,

The float valve in my cold water storage tank is constantly dripping. I want to replace it with a new one. However, the hole where the float valve passes through the tank has a small crack running to the rim of the tank (about 4 inches). My plan was to replace the float valve but move it over a bit, glue the crack and blank the old hole off. Is this advisable and is there a water proof glue that will hold should it ever be submerged?

I can't afford to get the tank replaced at the moment so any ideas for repairing the current tank are welcome. Just want to assess my options as i can't really afford to replace the tank right now.

Thanks

Tom

If the overflow is lower than this hole then it shouldn't get submerged.

However I would replace it and not take the chance.

As for the glue I have no idea if it would hold

Did the old valve have a stabilistaion plate on it? Metal plate that goes on the outside of the tank to support movement of the ball valve. You'd be amazed how often they are missed out. It may have caused the tank to fracture...

HI

i would replace the tank and from my experience there no such glue

Cheers for the replies chaps!!

No, there was no such plate fitted at all.

I can't really afford to replace the tank but may have to bite the bullet. Does anybody know roughly how much this will cost (parts and labour) - i'm not confident enought to do it myself.

Once you get the darned thing into the loft then it won't be as hard as you might imagine. All you need are tank connector(s) for the existing outlets, and hole cutter to match. Make sure you follow instructions that came with the tank and you can't go far wrong. [Instructions tell how far up/down holes should be drilled... ie overflow lower that ball valve]. Maybe some adjustments to cold feed pipework, but needn't take longer than a few hours

Cheers pal - i may well look into doing it myself then.

It's just the fear of starting it and not being able to finish it and not having any water etc!

 

[leakydave]

that fear is there for me now and then, and it is my job!!!
