Bought a new toilet to hook up into new basement bathroom, however when I installed the toilet it will not flush, if I loosen the bolts on the bowl slightly it will flush with out any problems. Could there be a vacuum happening? I also know that who ever plumbed the
3" pipe did not use a 90' the used a p trap, I do know that it is vented correctly, could this problem be caused by a bad toilet or could it be the P trap?? Please help.

Thanks

There is no P trap on a toilet drain, the trap is integrated into the toilet itself. How well did the old toilet flush? Is the tank filled to within an iunch of the over flow tube and does the bowl fill and swish when you try to flush?

It was all new plumbing done, so this is the first toilet to be installed on this line, but I do know the plumber put a P trap then the flange.

No P trap for a toilet, period. If a plumber did the install of the rugh in then call him. Maybe he plugged the drain with a rag, toherwise you would have been getting raw sewer gas out of the drain, something had to cap that pipe after the install.

BTW, tell us the answers to my other questions regarding the filling of the tank and the swish of the bowl.

Sorry for confusing the question the plumber put a p trap under gound then a 3' pipe coming straight up from the P trap then he capped it off, the toilet will flush fine when I allow air by loosining the bowl bolts, however when I tighten them up again no flush just swirls around the bowl, so I also know that there is no clogs.

There is no P trap on a toilet, even under ground. At this point I think you are better off to call back the installer and tell him you suspevt something he did is not working. A toilet is vented via a vent stack which usually terminates above your roof line. If this rough in is not vented it will not work properly and is not up to code.

If you insist that there is a trap there, could it be that the plumber put in a 3 line and trap for a shower and you have mistaken it for a toilet?

Just thought I'd ask.

Can you post a pic of the trap under toilet? I got to see this. Lee

Shower drains and traps are 2", crapper is 3" or 4", hard to make that mistake but give me time and I can find a way.

Just seems that I have heard that some places are going to 3" for showers. Maybe a bad memory.

They did talk about making washing machine drain lines 3" but it never got voted on when the new code was set.

I hope this guy post back and tells us what the results were to solve his problem. I have never heard of a commode acting the way he described except if the commode was partially stopped up.
