We have an older style non-low flow toilet.
We recently had the ball valve at the wall replaced, the plumber installed a 1/4 turn valve which is supposed to close/open with a 1/4 turn. He also installed a new fill tower for us. My wife has pointed out that flushes have been inconsistent.
My wife says that when solids are flushed, the toilet almost overflows. The water level rises to just below the lip (about 1/2" below). Sometimes a little bit of toilet paper comes back up too.
I researched this and found a test for clogs:
Pour two 5 gallon buckets in the bowl as quickly as possible. I did this and everything drained well, no overflow. The toilet seemed to handle it well.
Does anyone have any other ideas? Is there any way the fill tower could cause an issue related to the water level during a flush? The toilet fills to it's old level, albeit more slowly than before.
I don't want to call the plumber back in again, because it took him 3 trips to get the new ball valve to stop working.
