I would like to do something with the gutter drainage on my house. Currently they flow into buried, flexible tubing that terminate in poorly planned areas or are simply clogged. Downspout extensions are going to be trip hazards for the locations I need to fix. Therefore, I was wondering if anyone has had experience with “pop-up emitters” such as those made by NDS. Apparently, you use rigid or flexible tubing to connect the downspout to the emitter. The emitter is installed so that the pop up top is just flush with the ground. During rain-fall, the top is supposed to “pop-up” and disperse the water over the ground. They also have a “weep hole” in the bottom to drain any water when the downspouts are not actively “pushing” water out. Do these devices really work? What about in freezing climates? I’ve heard from a NDS distributor they can fill up, freeze, and cause backup in the downspout. Although, if they are freezing, the water in the downspout should freeze too so this point is mute.
Any input would be appreciated.
