I am going to plumb in a salt based water softener.
I am going to connect the waste pipe from the softener to a wastepipe
from a sink using a washing machine outlet kit.
The only advice I need is as follows......
Can I attach this below the u bend, or must it be above it?
My belief is that if I connect below the u bend, I will get loud glug
sounds from the sink when the softener is reconditioning or whatever
it is called.
Any advice gratefully received.
