| | | Kitchen sink still won't drain
After buying an old house, the kitchen sink didn't drain well, and since it wasn't hooked up to any "stink pipes" I added a Nonavent downstream of the trap, which draws air from above the trap. This worked great, but, after several months the good drainage ceased, and has become even worse than before. I suspect that the Nonavent has for whatever reason stopped working properly after 6 months or so. However, it could be that the vent is not high enough (since it's below the sink), or that the Nonavent doesn't work properly at a 45-degree angle. Any ideas for a better vent product, or better design. Would extending the vent to the top of the sink alleviate the prolem? Thanks.

I can't pull specs on a "Nonavent" AAV. Who manufactures it? If this is a Studor Vent it must be installed vertically. The height of installation doesn't make any difference since it's a one way valve. Perhaps the drain line needs to be snaked and cleared. good luck Tom |

hi tom,
Nonavent is the name on the part - that's all I know re manufacturer. It's a simple one-way part with a ~ 1 inch thin rubber inside of the air holes. So, as you suggest, these only work when installed vertically? When I installed it, I didn't think that would matter, assuming that the force of the vaccuum would be much greater than any gravity-related forces. However, if adding an extra 45 will fix it, I'll be on that ASAP.
- Can you confirm that what I have is the Studor vent? thanks, Jay | |
