Stopping guttering swan neck downpipe seperations

[hab1966]

My house has square downpipes, which connect to the guttering using a (built) swan neck arrangement.

The installation of the guttering/downpipe is pretty poor and the swan neck often seperates from the guttering, meaning rain water doesnt go down the downpipe.

We get a lot of debris on the roof which ends up in the gutters and then into the downpipes and the way the guttering was installed straight down to a grid cover, means the downpipes get blocked. To prevent this ive fitted shoes at the bottom of the downpipes which sit off the ground, meaning its the clips that hold the wieight of the downpipe in place.

I dont think the clips holding the downpipes to the wall are fitted properly either as they dont appear to have a firm grip on the downpipe - should they? Are they meant to hold the downpipes in place (vertically) or stop them from moving?

Im thinking it might be better to put a small self tapper through the swan neck to gutter joint and also through the swan neck to downpipe joint to try and make it more robust and stop the seperation. A good idea or a receipe for further disaster?

Other ideas gratefully received.

Quickest fix is to slide the downpipe back up into position, then tighten a jubilee clip around it on top of one or more of the clamps to stop it sliding down again

A slim screw right through does work and hold in place. But when fitted properly the brackets do grip the pipe but that will be a lot more inviting fix as you’ll end up needing new fixings in different place.

Black dry wall screw is how I usually fix these. Discrete and holds it firm. Assuming your guttering is black. Obv.

You can attach the fall pipe clips so they hold the pipe without it sliding down, though this doesn’t seem to have happened here. I use these if I come across the same problem 6 X 12mm self tappers, they won’t rust, you can remove them if you ever need to alter/remove the pipe and being only 12mm long, they don’t project into the rwp much and catch leaves etc.

Those must be too long surely?

We had one house that was overflowing when we moved in and someone had joined the downpipes with 40mm screws which made the moss and leaves build up and block it. Changed them for 20mm and never blocked again.

They come in varying lengths and honestly never had an issue.

Standard wood screws look a bit crap. If length is a concern, pre drill and snip the drywall screw to a shorter length.

That's what I'd do (s/s for longevity).
