I saw the terrible winds and fire on the news... evil weather.
Sorry to read about the tank, but obviously it was empty. Every container outside here is full of water, bugs and more. Hopefully you get rain soon. Hope is here... http://www.news.com.au/story/0,23599...l?from=mostpop |

My god Spatz, you'd better get some water into that tank! Is your Mum back in Oz? Night noises are bad enough without things going walkabout. Take great care, we need our gnomes. We had a wild day all day yesterday - easterly weather is a total mess up for my garden as it brings the salt. Today my peach, Lady in the snow apple and plums have brown leaves, what's left of them, and look disgusting. It's turned westerly now and look what we are going to get today. I'm going to concrete my garden when it stops.........
Grub, batten down the hatches - it's going to get worse........

Nice rain Cosi.... to quote a few passages from the above link...
As Adelaide sweltered through a 37C day that sparked bushfires across the state, the eastern states continued to enjoy good rainfall. One-in-20-year storms bucketed parts of Sydney and Wollongong yesterday, with 70mm falling in an hour in several suburbs. Current conditions 'classic La Nina' National Climate Centre head of climate analysis David Jones said the current event was a "classic La Nina", with warm, humid conditions and plenty of moisture in the atmosphere. The southern oscillation index - the standard indicator of pressure systems in the Pacific region - stands at plus 10, indicating a return to wetter conditions. Across the eastern half of Australia, a La Nina event became better established as sea surface temperatures dropped in the eastern Pacific and waters off Java became warmer than normal. The wettest conditions in a decade in western Queensland have put a spring in the step of locals and raised hopes that the Murray-Darling is in for a reprieve. The Bulloo Highway west of the township of Eulo has been cut for a week by the flooded Paroo River. 'Best rain in years' "We moved out here from Brisbane three years and we haven't seen anything like this before," said 11-year-old Samuel Baker as he played in the flood waters with classmates. "This is the best rain we've had in years," said Eulo General Store owner Gary Berghoefer. "The Paroo has been three or four kilometres wide in places. The rain will allow restocking on properties that have been hurting." Murweh Shire Council chief executive Chris Blanch said Charleville had 160mm of rain over the past month. "Years of dust is being washed off everything. Plants and trees are sprouting new growth all over the place. It's a godsend," Mr Blanch said. Warm water promotes convection and stronger westerly trade winds brought by La Nina blow moisture towards Australia, promising a return to good rainfall. The La Nina is expected to remain until about April. But Dr Jones warned that long-term rainfall deficiencies, especially around Melbourne, the Murray-Darling, Adelaide and southwest Western Australia, meant a return to full dams was "difficult to imagine". |

Bloody typical, Tasmania doesn't even rate a mention you'd think we didn't exist until people want to move here to escape the mainland weather cos they don't get any information.

At the moment we can only dream of rain. Enjoy it while you can, Grub.
Cosmic, sorry to hear your garden is suffering in this wind. Let's hope everything will recover quickly. Yes, mum is back and it was just so lucky that the tank was stopped by the pergola. She had a room with a view of a tank this morning. We've already moved it and tried to assess the damage. There are more pictures on the blog if anyone is interested.

Well, judging by the Cosi Report, it's sounding like a bumper season in the Apple Isle. But I wouldn't be taking a skinny dip just yet... http://www.cmar.csiro.au/remotesensi...ob/latest.html

Grub - What's that brown water off Sydney?
Oh yes, I remember now. |

That, my friend, is a school of native brown mullet. But deep water outfalls ensure they don't invade the beaches at least.
Was going to take a pic of my incredibly loaded sweet and hot peppers but I ran out of energy in the high humidity. Just fed the plants bloom booster. |

Hi Manto.
There once was a bloke called Manto Who was as full as goog of banto The heat of the Horsham sun Burnt a hole in his not inconsiderate bum Now that's the end of this ranto. On a serious note: you are right. La Nina is here with above-average rainfall for east coast. My tomatoes are big and healthy, but not so bloomin' lovely. Need more flowers. Also, some are doing the Cherokee Purple thing, as in, starting off gangbusters then just freezing after the first lot or two of fruitset. Kind of like they're saying: two kids are enough for me. But I have plenty of greenies all the same. Dwarfs only have about one fruit per plant... I am hoping they set more later in the year. http://mirror.bom.gov.au/products/IDR033.loop.shtml No much time for Daco. Last edited by Grub; December 7, 2007 at 03:55 PM. |

Grub - I think most Victorian's would settle on half the rain you've had is Sydney in the past two months. Then we'd be complaining about the humidity and losing our tomato plants.

[water tank repair]
From the look of those water tanks, any holes or cracks can probably be repaired. You want to bend them back into the shape they are supposed to have first. A plastic dead blow or rubber hammer should work for that, or one could use a regular sledge hammer with an old shoe, piece of tire, or something like that wrapped around the end of it. 50-year silicone, polyurethane sailboat caulk, any of those and a couple of pieces of aluminum flashing from a hardware store (used in roofing and in heating and air conditioning work) would work to seal it up, and thick silicone caulk at least has a lot of actual mechanical adhesive strength, too (I don't know how strong polyurethane is). The main concern is keeping the surfaces that the caulk/adhesive must bond to clean and dry. I worked on a job once assembling the outer skin of a commercial building out of aluminum extrusions and glass. The aluminum parts were cleaned first with MEK (methyl ethyl ketone), a powerful solvent, and then they got a once-over with rubbing alcohol and a clean shop towel to remove any dust and to make sure that they were dry before caulking. We used 50-year silicone to seal the parts, then fastened them with screws and bolts, cleaning off the excess caulk with alcohol before it dried. In some places the silicone would be a couple of centimeters thick in there. We got one back from the building contractor that had an out-of-spec part (wrong dimensions) on it, and we needed to take it apart and reassemble it. After we got all of the screws and bolts out of it, we had to pry it open with a crowbar so we could get a knife into it to cut the silicone before it would come apart. I have seen someone repair a 50-gallon aquarium with clear silicone, too. He just cut a piece of glass big enough to cover the hole with about an inch extra around the edges, cleaned all of the surfaces, put a few-mm thick coat of silicone on there around the hole, stuck the patch on, and let it dry. It never leaked a drop, and as far as I know those window-and-wall units for the commercial building are still watertight, too, decades later (at least mine should be). For any holes in the tank, I would cut a piece of flashing a little bigger than the hole. Fit it up and hammer and bend it as necessary to get it to more-or-less conform to the corrugated shape of the water tank. Clean the patch and the tank up, let it dry, and put the patch on the inside of the tank, with a thick layer of silicone under it. Press the patch into the silicone, leaving it maybe a centimeter thick under there. You can press more wet silicone into any gaps with something like a plastic spatula, until you have a nice solid layer under the patch. While it is still wet, you can clean off any excess around the patch with your spatula and rubbing alcohol. Once it is dry, the weight of water inside the tank will tend to press the patch into the hole, tightening the seal. Your choice on whether to use silicone or polyurethane caulk. An architect told me once that silicone was stronger and longer-lasting, but polyurethane was more forgiving (worked sometimes in conditions where a silicone seal failed). My impression from researching sealants in the marine forums is that polyurethane seems to be favored over silicone for marine sealants and adhesives by people who own and maintain their own yachts and sailboats, but their parts are invariably mechanically fastened as well as caulked (they are not relying on the adhesive strength of the caulk to keep the parts in place). If you could find some metal for a patch that was already corrugated with about the same corrugations as your tanks, that would probably be a big help. You probably don't want to mix steel and aluminum, though (the sealant in between might be enough to prevent galvanic corrosion, but I don't know that for a fact). Maybe you get lucky, and there are no holes, but if not, all is not lost.

"Must be winter in the US."
Yeah, I did not see myself commenting in the Aussie brag thread when I opened it up to read it. I had relevant information for Spatz's water tank worries, though, so what the heck. One would think you could weld a patch on an aluminum tank, but aluminum is a pain (expensive) to weld, and that stuff looks kind of thin, judging by those dents. Silicone or polyurethane will probably work better for a lot less money.
