Galvanised steel water tanks

HawkEye244 · 23 Feb 2020

Hi all, I've got one or two galvanised steel water tanks that I've been using to grow carrots in for the last few years.
I want to repair them and patch repair the holes so that they can be used to store water again to water my plants with. This would save relying on mains water (it's an allotment) as despite all the rainfall, in a couple of months there is likely to be a hose pipe ban lolol.
Can anyone suggest a method of doing this which is easy to follow and understand ? There are one or two small holes in places and I was thinking that large 22mm copper fittings under compression might serve as a good stop gap. What do you think ?

To be honest for rainwater you can get away with a lot. A bolt through the hole with a rubber washer. Or a scrap of plastic bigger than the hole siliconed to the inside.

You might be better off getting some plastic drums for storing the water and keeping the tanks as planters. you can usually get 200l drums or 1000l IBCs cheap 2nd hand

Thanks mate yeah, drums are ideal but I've not found any that aren't quite expensive. Even the blue food drums are quite pricey for a good sized one. I keep my eye out for unused dustbins and have a few but you can always have more water. I have planned to fit an IBC in another part of the plot but the area I'm focusing on doesn't have room for one, and as I recently moved the planters I thought it would be a better idea to use them for water instead of veg. I like them because I can dunk a watering can right into them and don't need a tap.

Keep an eye on gumtree etc, round here you often see them in the farm auctions (which are probably a bit thin on the ground in london!). Hang round industrial estates/factories and if you see any drums just go and ask. Cash of course

Need more info, does the silicone need to be a special aquatic silicone ? Keep in mind it will be subject to repeat freeze thawing

Any old tube of silicone should stick to the galvanized steel
