Replaced bay window gutter, water accumulates in bend

Hello,

I replaced my bay window guttering with a new set but left the existing brackets.

I expected as a straight swap to have no problems, other than the fact that Wickes guttering is a pain to fit. However one of the 130 degree bends is now accumulating a fair amount of water (as in around a foot either side of the bend and nearly to the brim of the bracket).

I'd rather not take the whole thing down and raise/lower the brackets but expect I'll probably have to. I've tested the brackets to make sure it's all clipped in correctly. But I'm posting here in case there are any tips or something simple I could do first.

Thanks

If it fills to the brim then it's fitted wrong mate. Bays are notorious for sinking. Large upstairs square bays with a massive tile overhang can sink as much as six inches over time. You need to start again making the centre of the bay the highest point and using a spirit level to the next bracket and so on creating a slight fall towards the outlet.

Typically, your highest point is the position furthest away from the RWP outlet - the RWP outlet is your lowest point. But this always depends on where the RWP is positioned on the bay.

FWIW: Gutter angle fittings are "self-supporting" - in that they dont need clips or brackets, they have integral slots/holes for fixing.

With respect: if the bay had sunk 6" then gutter difficulties would be the least of an OP's worries.
Why would the shape of the bay or the tile overhang have any bearing on a subsiding bay?

Thanks both for your advice. Thought I may have to do a proper job rather than a quick fix, but you can always hope...

Thanks Ree for clarifying - the DWP is to the far left of the bay so assumed I'd need to make the far right the highest point.

It's not sunk 6", luckily, and I suspect there may not be enough clips - the centre bay is about 1.5m wide yet only has one clip in the middle.
