No, it always had a slow flush. Its a Mansfield Alto RF. I looked at the
MaP study, and the combination only show a 275 gram MaP flush performance,
far lower than many others available.

Maybe it's lower, but 99% of them still flush fine, right?

I think it needs to get replaced.

What kind of toilets do you have in the other bathrooms?

And of course the other guy was right. Your house water pressure has
nothing to do with how it flushes. As long as the toilet tank fills.

Does the toilet tank fill? Could you raise the level without going
above the overflow tube that goes into the bowl?

Did you do as I asked and take the lid off the tank and watch what
happens when you flush it?

Anything unusual?

How do you know it's not the vent? In my case and many, the
downstairs toilet uses a different vent from the upstairs toilets.

Not if the problem is venting.
