Fluidmaster 8300 Flush 'n Sparkle Automatic Toilet Bowl Cleaning System with Bleach Cartridge, 1 Count (Pack of 1) ( Packaging May Vary)

I just bought this Fluidmaster cleaning system to replace an older system I had that uses pellets. Although that system was a bit cheaper to run, it was hard to dispense the pellets without touching them--whereas the Fluidmaster cleaning compound comes in a sealed cartridge. This system is VERY easy to install and works great--even though I was attaching it to a non-Fluidmaster toilet valve. Here are a few things to note based on many of the reviews I read:I HAVE A NON-FLUIDMASTER TANK VALVE AND THIS CLEANING SYSTEM WAS VERY EASY TO INSTALL!1) You have to make sure to TURN OFF THE WATER VALVE TO THE TOILET BEFORE YOU BEGIN! If you try to change ANY toilet tank part with the water still on, you WILL get sprayed. (FYI--the water shut-off valve will be at the end of the pipe coming out of the wall below the toilet tank. it will have a short hose attached to it that runs up from the valve into the bottom of the tank that connects to the tank valve. Turn it to the right to turn it off and to the left to open it.)2) There are only two connection points for this system: A) The tube that is attached to the upper part of box is the "intake" connection. (You'll know it's the UPPER part of the box because this is also where the cleaning cartridge is installed.) This "intake" tube is attached to the nipple on the top of your tank valve--that long, skinny plastic tower that brings in the water that fills the tank and also controls how much water comes in.) B) The tube that is attached to the bottom of box is the outflow tube. It takes the water that has entered the box through the intake tube, that then flows through the cleaning cartridge, and comes out here to go into the toilet overflow tower. This second tube actually comes out of the bottom of the cleaning box and then is re-routed so it goes back up long the side of the box so it is ready to be attached to the overflow tower in the middle of the toilet tank. Without this re-routing, the outflow tube from the box would essentially be floating free in the tank.3) It is possible that in order to ship the cleaning systems, that outflow tube that descends for the bottom of the cleaning box is drawn too tight and might be slightly pinched. To alleviate that, just pull slightly on the left side of the of that outflow tube. That left side of the tube will move down a little adding some length to the tube and eliminating any pinched areas in the tube.4) Slip the cleaning box on to the back edge of the tank so that it is a couple inches to the right of overflow tube (that tower in the middle of the tank).5) Attach the the free end of the cleaning box's upper intake tube to the nipple on the top of the tank valve (that long skinny tower that lets the water into the tank--the one you turned OFF the water to in step 1). (You might need to cut the rubber intake tube from the cleaning with a pair of scissors to get the length right, but once you've attached the box to the back of the tank, pull the intake tube toward toward the intake tower nipple and snip off the extra tubing. If you snip off too much, just push the cleaning box toward the intake valve tower to make up for that extra space.THIS CONNECTION WITH THE INTAKE TOWER NIPPLE WILL BE TIGHT!! IF IT WASN'T TIGHT, IT WOULD LEAK!! IT MIGHT TAKE SOME FORCE TO GET IT ON, BUT THIS IS NOT PECULIAR TO THE FLUIDMASTER SYSTEM--ANY SYSTEM WITH A TUBE--AND ALL OF THESE HAVE TUBES--WILL REQUIRE SOME FORCE. IF YOU CANNOT GET IT ON, REMOVE THE WHOLE SYSTEM FROM YOUR TOILET, TAKE IT TO A FLAT, HARD SURFACE, AND ZAP THE END OF THE RUBBER TUBE WITH SOME HOT AIR FROM A HAIR DRYER--ONLY A FEW SECONDS, OTHERWISE YOU Will MELT THE RUBBER AND HAVE TO CUT THAT MELTED PART OFF!6) Once you have attached the box's intake tube to the water valve tower nipple, connect the box's outflow tube to the tank's overflow tower with the included clip (or, if you have another type of overflow tube other than Fluidmaster, you can attach that tube accordingly.)Don't forget to turn the stare to the toilet back on!

These work great! I prefer the bleach (clear) one vs the blue. I don't knoe if the blue would stain, but I'd rather not find out. The wY I know it's time to replace is when I can see some of the "film" build up again. That's also HOW i know it's working!Best part is, the chemicals don't sit in the tank, which could erode the rubber and plastic parts.I also have a bidet, and this adds the cleaner right before it hits the bowl. My bidet uses the water supply BEFORE it goes to the tank, so I'm not shooting cleaning chemicals up my...well, you get the idea.Whoever came up with this is a genius.

Doesn't work as well as expected or advertised. I have very hard well water and hoped this would be the answer for a clean toilet but I'm disappointed with the results. It was easy to install though.

As a licensed plumber I had been looking for something for a long time to recommend to my customers to keep the ring in the bowl, so I tried the product at our house first myself to test it out before I decided to recommend it to my customers,.and I have to say it works really great and it does keep the ring out of the bowl. Now Fluidmaster recommends replacing the cartridge every 3 months, however it varies from household to to household, it all depends on how often the toilet is flushed. I wish they would have recommended the amount of flushes for each cartridge rather than months. if you're Flushing a lot more often than usual I would recommend replacing the cartridge every 1 1/2 to 2 months as it can run out before the third month. I replace ours every two months in my household. With that said you will just have to monitor it check the cartridge from time to time see how fast it's dissolving to determine when it needs to be change it out, but the product works really great and I do recommend it to my customers. (A little disclaimer) here, we personally have a water softener with a water conditioning system at our home. If you have really hard water and you don't have a softener or conditioning system at your home the results May very. I don't have enough data on that yet to make that determination vet. Another common question that a lot of my customers have about the product is, does the chlorine going to affect the parts in the toilet tank itself? and the question is NO the way it's set up in the toilet tank it diverts the chlorinated water into the filush valve tube and down into the bowl on each flush so the chlorinated water only goes into the bowl not the toilet tank itself. And this product is very easy to install. Another question I get will this work on any toilet and from what I can see it works on just about any toilet I haven't come across one yet that it didn't work on.

I have been using this product for years. Once you buy the initial system which has lasted me for years, I just buy the refill cartridges as needed. Depending on the size of your household (mine is small), I need to replace cartridge about @ 3 months which is cheaper than other toilet tablets and does not harm the gadgets inside the tank. It's very simple to replace, and works beautifully to keep the tank clean.
