   All of these are clots waiting to happen. Gutter guards are the best options, and there are only a few systems that work without needing constant attention. The level of maintenance is dependent primarily on what kind of tree debris gets into the system (oak leaves are heavy, for example, and tend to “glue” to surfaces).

   我觉得工作良好的唯一的天沟守卫看起来像是在排水沟顶部的刚性金属面板。碎片主要越过侧面，而水则进入排水沟。

   我不必担心带状疱疹的细砂碎屑。水速度足以敲打那种松动也可能足以防止管道中的罚款。

   I don’t like any of the filters that go in the downspouts. These types of filters are catching debris that should have been filtered out in earlier stages, IMO.

   Thanks Bill. Gutter guards as the first filter makes the most sense to me also. Just need to figure out which kind is best.
   至于落水过滤器，我所在的代码需要它们，因此我必须弄清楚要使用哪个。

   c l,

   I’ve seen a couple of impressive rainwater harvesting systems here in SW New Mexico that include “first flush” tanks, which are simply small tanks that first fill before allowing overflow on to the main storage tank, cistern, etc. In our dry climate the intent is utilize the captured rainwater, so some sort of storage is involved. The “first flush” tank captures debris, much like a sand separator for a well. However, leaves and floating debris must be kept out with gutter guards or some other device.

   Good luck!

   At my house, I am in the gutter guard...

   虽然有些系统比其他系统更好，但从未找到一个不涉及我的系统...

   彼得

   PS - from southern VT with a slate roof where gutters are most often an annual installation cost...

   我发现带有大型网状滤清器的沟槽与带状疱疹的颗粒一起堆积。没有对细网的经验。我目前的位置有穿孔的金属。绝对可以将所有叶片碎屑避开（这里主要是橡木/枫木），尽管我有金属屋顶，但无法对颗粒发表评论。

   That German downspout filter looks pretty neat. One thing might be worth while to look at is a first flush diverter. These are simple/no maintenance.

   For roof water that is going into a dry well or that will be used for irrigation, there's not much need for a first-flush filter. Those are really more for water going into a cistern for eventual drinking water.

   我发现“天沟头盔”风格的天沟守卫非常有效，可以使大碎片排除在沟渠之外。但是，它们在容易发生的地区可能表现不佳。我在沿海地区4，所以这里没有太多的长期冰/雪。如果您有体面的天沟后卫，则可能没有必要。如果您的本地代码要求它们，请选择便宜的代码来满足代码人员。带状疱疹的矿物颗粒将永远需要堵塞干井或水箱。

   我已经检查了用于屋顶排水的干井。作为许可过程的一部分，每10年我周围的某些地方需要进行检查。我主要发现，少量的有机碎片可以有效地进入干井堆肥。如此之多，以至于在某些情况下20年后，井中的石头也很干净。

   Unless you've got lots of big trees (especially evergreens) hanging over your house, my feeling is: Use decent gutter guards, with a coarse downspout filter as a backup. Don't worry about the fines too much.

   Does anyone have any experience with the fine mesh type gutter guards? Sounds like those might be the best?

   同样，由于有一个无法具有天沟电荷的区域，因此对特定落水过滤器的任何经验都将受到赞赏，因此落水过滤器将是唯一的过滤器。

   CL，我使用了这些，它们运行良好。

   如果您谈论的是实际上进行的排水沟守卫，则刚性面板类型往往最有效。滚动的东西没有，安装后会产生“驼峰”的任何东西都会倾向于在屋顶边缘积聚碎屑，这是一件坏事。您希望在坡度向下的平面面板朝向边缘。您希望水掉入排水沟中，但碎屑可以越过边缘。

   I saw one gutter guard that looked like lots of very closely spaced slats (something like one side of an A coil for an air conditioner) at a trade show a few years ago, but I can’t find the info now. It looked like it would work really well.

   If you’re asking about downspout debris filters, I don’t use those myself.
