Yest,
Just pulled up vaillant MIs of random model.
WHAT'S this
The discharge pipe from the boiler condensate drain
must have a continuous fall (45mm per metre) and preferably
be installed and terminated within the building to
prevent freezing. The condensate discharge pipe must
terminate in a suitable position, e.g.:
a)preferably the discharge pipe should be run and terminate
internally to the house soil and vent stack (at
least 450mm above the invert of the stack). A trap
giving a water seal of at least 75mm (3) should be
incorporated into the pipe run.
Wow, sounds like it's the best thing I could do then, thanks mrgassafe.
Mickyg - no issue with me here, I know the condensed water had to go into plastic pipe, I just didn't know if it could go into the soil stack. Thanks everyone.
Baxi MI's show a diagram of an internal soil stack, with the connection a min of 450mm from the invert.
Be aware of internal pressures in the existing drainage, and not just from the stub stack. Positive pressure could blow the water out from the trap and cause lock out. (Not so common, but possible) I think baxi even states that.
Read the MI's for the boiler.
