I have seen recommendations that the outlet has to be about 20ft away from the house foundations and this seems OK to me. However, this means I will have to have the hose either above ground or buried to do this (it currently comes out under my deck - too close!).
Anyway, given that I live in an area where freezing is inevitable, is there a specific type of hose/cladding I should look for to combat this or is burying the hose acceptable? Obviously, I wouldn't bury the open end but I'm definitely going to be replacing and re-routing my sump pump hose when it eventually stops raining so much (some day).
