This is kind of gross but here goes: I've installed a American Standard Champion based on reviews it's had concerning its flushing abilities. I've found they were accurate... to a point. Anything in the bottom of the bowl WILL go down in one flush every time. What it doesn't do so well is rinse the sides of the bowl.
I'm trying to come up with a way to add some sort of hose assembly to the stainless steel supply line that would allow me to hose off the inside of the bowl as required. I saw something made in the UK but it refers to poking through a 15cm solid supply line with a saddle valve .... which I don't think will work with the braided steel line I have from Lowes.
Anybody got any ideas? Smart asses need not reply though I know it's going to kill you to keep quiet.
