Is it normal for a house built in the mid 70's to have the roof rainwater
drain-off ending in a soak-away?
I'm building a largish patio and because of the area am including a driveway
drain at the lowest side. I was planning on splicing into the rainwater
drain but when I dug down to find the drain pipe I found that it ended in a
soakaway. It's made things much simpler for me because now I can just feed
the drain from the patio down into the soakaway as well rather than having
to break into a run of drain pipe. I'm just surprised, however, to find a
house rainwater drain ending in a soakaway!
