Possible Water Pipit And A Mystery Stint

Darts Farm, Topsham, Devon 
I was alerted to a possible Stint species that was spotted very distantly from the hide so I couldn’t resist calling in on the way home. After a search I couldn’t locate a wader that resembled a Stint but I did get what I am 95% sure was a Water Pipit. The bird was always at the far end of the channel, light wasn’t great and the tussocks obscured view a lot. However, the bird was a plumper looking bird, it had a purple tone, a very bright breast and very little streaking. I couldn’t make out a supercilium though, which I would have liked to help clinch the ID. Also on site were a good number of Common Reed Bunting and Common Chaffinch.
