The pop is secured by two rivets, but I'm guessing that after drilling those out it's still going to be "stuck" to the gutter with sealant. Can anyone advise on what tools or chemicals I would need to "unstick" it without much difficulty? Sorry if this seems like a weird question - just trying to anticipate all aspects of the installation as I don't want my plans to come unstuck (haha) by something silly like a pop that's impossible to remove. Re: Removing a gutter downpipe pop/nozzle 2Dec 12, 2010 10:47 am Its a lot of work to do just to install a downpipe. why not slip the DP together, position it, then slip it apart connecting each end, the DP straps will stop it moving. But If you want to do it as asked, Ive found pops not too dificult to remove after removing the rivets and cutting through the silicone with a knife or similar.

Unfortunately the existing wall plugs for the straps aren't in a position to support the adjustable offset directly. I made a diagram which shows how everything will fit: Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ So in terms of installation procedure I can't really see how I can get around removing the pop, riveting the downpipe overlaps on the ground then reinstalling the pop. Unless I do the riveting on the visible sides, but even if I had matching Colorbond rivets I'd still like to avoid that. Want it to look as close to a top notch installation as I can manage. The thing that had me worried about removing the pop in this case is it's been lodged there for 15 years and looks almost fused to the gutter Re: Removing a gutter downpipe pop/nozzle 4Dec 13, 2010 5:24 pm Oh, I assumed you were fabricating the offset from a straight length, which would have avoided the join mid-offset and moved it further down the upright section. The only problem you may have is if the pop is soldered into the gutter, but they haven't been done like that for yonks as I think the current crop of guttering tradies simply cant solder Ive replaced most of my rusty sheet metal downpipes (not because I cant solder) with pvc, which is OK once its painted to make it UV proof. Removing the downpipe adaptor at the base and gluing into the stormwater pipe, so its sealed from the pop to the street, should there be a bit of back-fall. Its the method used by most builders here. Arfur Re: Removing a gutter downpipe pop/nozzle 5Dec 13, 2010 7:46 pm Being a first timer I went with the adjustable offset, but yeah, the extra overlap means it doesn't look quite as good as the roll-your-own type. Turns out I do have one unanticipated problem removing the pop - I can't drill the rivets out because the pop gets in the way of the drill, putting it at too much of an angle. Looks like I have to get tin snips to make some room. Maybe they'll help for cutting the downpipe to length as well - had planned on using my hacksaw but when I sawed off a short length today as a trial run, it was a pain in the butt. Too late to consider the PVC option - already pickup up the parts. Re: Removing a gutter downpipe pop/nozzle 6Jan 09, 2011 4:05 pm Anyone know how to get around this procedural catch-22? - If you rivet the pop/nozzle into position first, it gets in the way of the downpipe, preventing it being raised into position. - If you raise the downpipe into position first, it doesn't leave enough clearance for the rivet gun to be aimed straight to rivet the pop into place.
