Hi

A couple of dumb questions...

1. would there be any problem with reducing the condesate outlet pipe
from 22 mm to 15mm a couple of feet from the boiler, running it under
floorboards for approx 30 ft and then feeding into 40 mm kitchen waste
pipe? (trap in boiler)

2. how would i connect the 15mm pipe to the 40mm one?

thanks
