Surface Water Discharging into a Foul Water Drain Drainage and wastage systems and plumbing help, advice and answers

[Jim A]

Hello all........Can anyone advise me whether or not it is permissible for surface water to enter a foul water drain?.

Hi Jim,

Yes if its a combined drain.
The problem exists more if you want to put foul into storm.
Storm into foul I would do on my house without a second thought.
