My home doesn't offer a great place to eject sump water due to a very level landscape. I'm thinking of adding 3-5 standard pop-up sprinkler heads to the output line. This would allow better distribution of the ejected water than though a single output point.
However, since the system would need to be under pressure, I'd have to disconnect it seasonally and blow out the lines to prevent freeze damage.
Are there any other obvious downsides to this plan?
