("Bef" should be in the title, the mod is welcome to change it)
We have an outbuilding where the water flows the wrong way in the gutter, resulting in premature rust. I pointed this out to the sheet metal worker after a year upon discovery, who thought "you just need to push up the bracket." I don't want to argue with him, I'd rather do it myself and correctly.
But it's not the adjustable type. See picture. It seems really tight, and not something you can easily "bend" directly. Suggestions on how to raise the first two meters of the gutter?
Plumbers have a special tool for bending a gutter bracket. I think it must be used when it is completely disassembled.
Correct, a bracket bender is used to bend the "shaft" on a traditional gutter bracket, which initially has the shape of a J. The placement of the bend determines the height of the bracket, but you cannot change the height once the bracket has been bent. A small adjustment margin can be achieved by "pushing up" or "straightening out" the bowl of the bracket itself. If it's a larger adjustment, you probably need to replace the brackets. Easier said than done (= practically impossible) if it's a metal roof where the bracket is nailed under the metal, unfortunately.
