Calcium buildup

If, as Oren suggested, it's the rim jets that are getting blocked then you can spray CLR there. It's odd that a plumber would not know this, though. Get your water tested to see if you need a water softener.

I'm sure the pumber knows, but that doesn't make him any money. Vinegar will have the same result as CLR

Get your water tested ( usually free for basic test) and you may find it very hard. Softener will make a difference.

Cadet has a good reputation. Most of the 1.6 or 1.28 toilets today perform well. My preference is the models that are comfort height and elongated bowl with a slow close seat.

I got the comfort height, didn't think about the seat, plumber brought a new seat, then I remembered ours was a slow close, got him to move that between toilets.

I'll see about a water test.

Look into installing the ScaleBuster where your cold water line comes into the house. It has great reviews and I will be doing a bathroom remodel in the next few months (hopefully) and will have one installed then. Can be purchased at Home Depot and be sure and read the reviews.

I have this toilet and have had it about 6 or 7 years. I recommend it HIGHLY to anyone wanting a powerful low flow toilet. Well worth the few extra bucks compared to other toilets.

I'll look into that, thanks.

As I said, so good so far, but thanks for a longevity report. The cats seem to like the box it came in. :-)

Hahahahahaaaaaaa, cats like most any box they can get into.
