There is a bit of a bleach odor to the water. You'll notice it missing. The unit is very easy to detach, so you can always check t see if there are still crystals in the unit. I have not been able to find the refills anywhere online. I only paid $6.97 for the original unit, and the stores used to carry the refills. I can't find refills anywhere. Hope you can help me. Trust me,it is very easy to detach the unit to check if you still have the crystals left in the unit. I'm no handyman for sure.Daviddajinwi@yahoo.com

lift the lid on the tank and then look to see if there are any white crystals in the dispenser if not replace the cartridge or if you can not smell chlorine when you flush replace the cartridge

Good question. I installed one in each of the three toilets in the house almost 3 months ago and they are still working at 100%. No rings and no sign of dirt. As soon as I start seeing a ring, I'll replace them. I hope this helps.

Since you installed it I'm sure you know how to troubleshoot it. So just disassemble and write a complaint to company telling them what happen and I'm sure they will gladly replace yours for a new one.

I don't have an answer. Nothing in the instruction book tells anything about a replacement. Sorry.

You can replace it from the top. It's a little snug, but it fits and works great!

No, I can't since I already did the replacement. It was simple, only took me 10 to 15 minutes, with simple tool (no special tool needed). It works great, as good as new.

I do not know if it is replaceable, but they do have a guarantee. Mine works great!

I think so... If you replace it, there are videos on YouTube that show how it's done. Fairly simple.

It has a lifetime guarante. Contact Amazon or the company to see who to get it replaced.

I would think from the manufacturer. I haven't changed mine yet. It would depend on how much heavy use as far as when you have to change it.

I don't know. Just replaced and I don't know how long it will last either. But sure looks better than before.

Write to the company. Since it has only been two months they will probably replace it.

Unfortunately I have not had to replace mine yet. So I don't have the answer.

Open the back and remove and replace. Be sure to replace the same way as the one removed.

I bought this one as the original didn't hold up. It is doing well for me. That is why they make replacements. If they really held up there would be no need to replace it.

No, you will need to replace it with a new one. But depending on how heavy the use is, one can last at least a year.

In the discription it tells what it replaces.look up your model it will give you replacements if need be.
