Anyone have any luck welding up a 1/8" pin hole in a water well tank? It's in this area:  10 years old, supposedly a lined tank, but looks to me like it rusted from inside out.. A wood screw or roofing screw with a rubber washer temporarily? |

For what it's worth. I would drill a bigger hole and insert a rubber expandable plug or drill a 1/2" hole remove the outlet pipe feed a SS valve stem with a piece of wire thru and then you have a way to unload water log by adding air occasionally.

Well, I did the sheet metal screw with a rubber washer for now and it's holding 100% for now, not even a drip. I already had an air shrader valve on the side of the tank, with the float valve thing, so adding air is not a problem. It's always done it automatically. I'll be sourcing a new tank but for now, we're back to having hot showers and running water.
Looking at it closer, there is some rust showing up on the sides of the tank, (probably because I've had a reflective insulation shield on it for 10 years. I won't put it on a new tank.)
It's also an 80 gal, not 40 gallon tank.
There is something in my water that causes galvanize to degrade pretty quickly. I've already had to replace 4 galvaized ells in my plumbing and replace them with PVC. Sulfur maybe tho my water doesn't smell or taste of sulfur.
Do they make affordable vertical poly tanks for water wells?
Do they hold up to UV?

Idk about poly tanks . I know a 80 gal upright galvanized tank is about 600 bucks . Had to replace one last year the hurricane broke the inlet galvanized pipe when it blew the pump house off the foundation.

I had a coated (lined) galvanized tank that only went about 8 years.
The problem with the screw fix is generally the surrounding area is degraded. It is never just the pin hole. You could have a weakened 6 inch area. The leak is just the tale tail evidence. If you can get a 12 inch section surrounding the pin hole painted with sealer, now that you have the leak plugged, you could be good for a while. Flex seal or something of that nature.
Sun is hard on the poly tanks. They last but solar rays get the best of them. Eventually. But still they last longer than galvanized.
