What should I do with my sump pump drain?
My sump pump drain exits my foundation about 2 ft underground. I understand that sump pump drains are supposed to escape to air, but mine was not built that way. I inherited this current system from the builder and previous owner.
Currently, it is connected to a drain pipe that runs about 200 ft into a dry well. The area around the dry well is typically swampy which isn't great but I don't really mind because it's at the edge of my property. The problem is that when the previous owner installed this system, he used corrugated pipe which has become damaged under my deck, about 30ft from where it exits the foundation. I can hear it gurgling when the pump runs, with water running up from holes in the pipe. The area under the deck is always wet, and I want to fix it before it sinks my deck footers or causes a sinkhole situation. I also think it makes sense to disconnect the dry well system because I don't think the area has enough slope to properly drain.
I plan to run another 50 foot solid PVC drain pipe a different direction to a better sloped area, and have it exit the ground with a pop-up drainage emitter. The question is, since my drain exits my house underground, should I bring the drain line above ground and install an ice/freeze guard section in case the drain pipe freezes, then go immediately back underground and run to the pop-up emitter? Or should I just leave the whole thing underground until the drainage emitter? I understand the reasoning behind the ice/freeze guard and escaping to air, but it seems to me that doing so in my situation would just cause more potential for freezing and backing up into the sump.
I have (crudely) drawn 2 pictures to illustrate my situation. First, marvel at my mad art skeels, then give me good advice, please.
