Condensate cannot go into Foul Drains when a Septic Tank is used

[septictank]

Just a 'Heads Up'.
Condensate from Condensing Boilers MUST NOT be drained into Foul Drains when a septic tank or sewage treatment plant is part of the foul drainage system. The condensate kills the bacteria in the tanks due to its high acidity and the sewage treatment stops working.

thanks for the headsup and welcome to the forums

Surely all sewers go to a sewer treatment plant?

Useful to know, better if there is something to reference.
I know of a lot of steamers running into septic tanks.

Presumably - that's alright as long someone remembers to change the cartridge every year!

I live in an area where most installs involve a septic tank and the ground is also clay so a soakaway isnt possible, I had to check this out and this is the answer:

I would have thought the amount of condensate is minimal compared to bleaches and other "Germ" killing detergents put into the drains.

Seems to be info about it tho'
