Have just built a house in N Auckland.

Used Marley's Magnum because I needed to have few downpipes (3 for 300 sqm).
Which met the recommended flow capabilities.
So the last thing I needed was a flow restriction at the leaf diverter.
So I looked for a model with no 100-to-80 restriction.

In the finish, I bought 3 Leafeater Ultra 100's from Bunnings (on 2020-10-20).
Probably through their special orders desk - but it wasn't a long wait.
I did consider getting them from Oz - but Bunnings was simpler and the differential $ wasn't great.
I do have a Trade account at Bunnings - but that only reduced the cost by a few dollars.

I should have added that they've been very effective.

I can get that a clump of leaves could block the leaf slide entry but not that the joints above the slide would leak faster than the rain filling the gutter could reach the 2nd downpipe. Is there a very loose fit on the slide? With 2 downpipes the gutter probably should be level so you get sharing from the start.

Either they're using the wrong stock photo or those look remarkably clog-prone, it looks like it's a 100 in, 80 out with some sort of S-bend for things to jam into, and no easy way to see if there's leaves stuck in it. M10 has some cut-open photos but it just looks jam-prone with that hood very close to the leaf fingers, if a bundle of leaves goes down there with the first flush it'd jam between the fingers and hood wouldn't it?

That was the general thinking, and some is going down to the second downpipe, but a lot of it is forcing its way upwards out of the join where the running outlet fits into the downpipe. It's not particularly loose, in fact it seems a fairly tight fit, but there's obviously enough water pressure to force quite a bit of it out there. It's an unexpected failure mode.

What's the arrangement between downspouts and drains? This was my situation:

A: B:

|| ||

\\ ||

\\ \

================= --> "Stormwater" (actually, "nowhere").

Downspout A was "upstream" of downspout B (i.e., joined the drain first / uphill). Downspout A was also higher than B and collected more water. For us, the blockage was downstream of both, but downspout B backed up much sooner and higher than downspout A. To my non-plumber reasoning, the blockage logicically had to be in B before it joined the drain. If the blockage were after the join, then the water level in both A + B surely should have been the same? But it didn't actually seem to work out this way in practice - I'm guessing because the pressure needed to overcome the weight of the water already upstream of B is greater than the pressure needed to force it out through the joins? Some water was also going down the drain so I suspect that added further complications to my 5th form siphon physics analysis.

But if you're having signficantly different flows in your A + B, suspect that points to some kind of blockage somewhere.

That one looked better in the editor than as posted. Additional line breaks.

Redundant downpipes about 3m apart feeding into the same drain.
