Hi everyone. I'm really hoping someone out there will have a solution for me.
Background info:
I have a kitchen sink that is vented with an In-Line vent or "air admittance valve" so it does not connect to our main vent for the rest of the house and thus does not vent through our roof. The vent was installed during a previous reno by the former owners of our home. The sink has had the odd difficulty draining but nothing major until now.
The problem:
The sink fills with water and empties a few hours later.
*Note. If I take the cap off the vent and depress the spring then the tub will drain a few millilitres then begin to fill with water.*
What's been done up to this point:
- I have checked the trap for debris and found nothing
-I disconnected the vent and ran an auger down the line looking for any obstruction and found nothing.
- With the vent off and the sink empty I have run the water until the sink is full. The sink does not drain and the vent fills with water.
I've attached a picture of what the current plumbing looks like for greater detail. Yes, that is a laundry tub in our kitchen. We are currently undergoing our own reno and waiting on our new kitchen to be installed.
Thanks to anyone who can help.
