Thread: Calling all Cockies!!

i no you said you cant get in the tank but our old steel water tanks we cemented up so you might be able to cement up the holes or put a bit of steel over it

I used Bondcrete (IIRC) on the outside but only as a very temporary fix due to the tank leaking in more and more spots before long.

Look into a product called crystal clear, It was designed for concrete tanks but may work on steel. To check to see how many hole you may be dealing with at night put a light in the top and see how much shines out the sides - then you will now if it is worth fixing or turning into a wood shed.

You could weld it, but gal fumes are NASTY.

Maybe solder/brazing?

Any suggestions on lining, patching it? It has an offset hole in the top, so physically getting inside the tank won't be possible without getting the can opener to the lid!

The only permanent solution I've seen to seal leaking gal water tanks is to line them with cement. Works great over a long time, but I've never seen how they do it. They must have some reinforcing in the cement - chicken wire, perhaps?

I have used bondcrete a few times with mixed results. If you are going to cement the inside of a gal tank you would be better off buying a new one and would probably be cheaper. Have you looked into putting a plastic liner in?

You can get sticky fibreglass repair patches that should do the trick. They harden with exposure to light, and will take quite a bit of pressure.

Or perhaps something like ferro-pre putty.

Or Tek / roofing screws, with the rubber washers.

Or, a really quick, cheap and nasty fix is to poke plastic bags into the holes (with a stick). Once the bag pokes in far enough, the water pressure pushes it back against the inside of the tank, and seals the hole........... until the bag starts to break down.

I thought they were available but unsure from where?

Is there some sort of sealant (silicon/bitumen, etc) which could be applied from the outside? I'd imagine most solutions would need to be done from the inside?
