Toilet bowl drains slowly.
i have a toilet that i just installed that slowly drains the bowl after the flush is complete.
It flushes perfectly, tank and bowl fill up at the same point, everything is good until the fill valve shuts off and then the bowl water slowly drains. i checked the gaskets on the flush valve, replaced the flapper, and checked the clean out with no visual obstruction ( however its kind of hard to see all the way back to where the Toilet tees in).
but heres the kicker, when i turn the tub on full blast (which is up-hill from the toilet on the main drain) the toilet will hold its level in the bowl.
Thanks any help would be great.
