Relax, plenty of acid rain has gone into that soakaway over the years.
OTOH, if it is an old cast-iron downpipe ..... :-(
Boiler condensate to soakaway

And no fall at all over that length ?
You mean a run of 100mm pipe then.
And the connectors for those pipes have angles of 87.5 degrees for a reason, it's to allow a lateral pipe to have the correct fall and join a vertical stack without twisting the seal in the socket.
It's mildly acidic, like tomato juice, which is why tinned tomatoes have a plasticky lining in the can.

There is a house near me where it leaks onto a concrete apron and has badly stained it.
Same for the stowaway, although paving slabs may require attention...
Why not?
Quite - ours did in a previous property.
Just how bad a thing is this? A friend of mine has just had this sort of installation and the WB website says
"It is acceptable providing that the cast iron pipe will be regularly flushed with water from another source" otherwise "corrosion and premature failure of the cast iron pipe".
In her situation the condensate is fed to the cast iron stack of a secondary (little used) bathroom.
How often should she flush the spare bog to satisfy the requirement of "regularly flushed". After all a Preston Guild is regular.
Is failure likely in 12 days 12 months or 12 years?
