The condo where I am doing work is already having leaks from the pro-flow two handle kitchen faucet cartridges after only 3 years. They look like imitation Moen 1224's. I also hate how the pro-flo toilets use old style ball cocks(I don't think you can even fit a Pro 45 in there since the hole is so close to the back of the tank. The glazing is also missing at the very bottom of the bowl as some have already mentioned. I doubted the problems with the tank to bowl gasket until I saw the ridges in them...right where it is supposed to seal against the bowl. I will NEVER purchase their crap and will advise against it's installation.
