When I flush the newest toilet in my house there is a massive bubble that comes out of the toilet bowl.
The toilet flushes incredibly slowly.
The bubble does not come from the drain, but from the small hole near the front that shoots water into the drain. I don't know what that hole is called, because for whatever reason I can't find a diagram that shows that hole.
Here are some items:
- I have done the bucket test, and dumped a 5gal pail of water into the toilet. This drains pretty much instantly and there is no air bubble.
- I have 3 toilets in my house, 3 showers, and 5 sinks, only this one toilet drains slowly.
- I appear to only have one sewer vent on my roof, and I have sprayed a jet of water down the vent for several minutes, there is no water backup and I don't expect there is any clog.
- The toilet is rarely ever used, it's in the "guest" part of my house. I have used Draino on it.
- I have plunged it, there doesn't appear to be any backup.
- I have tried poking around in that hole where the bubble comes from, but there doesn't appear to be any obstructions.
I've seen some sites where people mention a misaligned "small hose that feeds into a bigger hose" but there doesn't appear to be any hoses that fit that description in my tank.
Anyone have any idea what this issue is?
Unfortunately you can't really see the vent that I found to be clogged, it's very hard to see it. The rusty smudge near the top right of the picture is where the clogged vent is. Although, I'm thinking it may not be a vent at all, possibly a crack?
I replaced the toilet with a much better one. An American Standard Champion 4. Now it flushes like a shotgun.
The moral of the story is: don't buy cheap toilets.
