Fluidmaster 8302P8 Flush 'n Sparkle Automatic Toilet Bowl Cleaning System Bleach Replacement Cartridge Refills, 2-Pack

With experience over the years trying many different products, I've found that the only toilet cleaning solutions that are effective are those where the cleaning solution actually passes through the flush system (i.e., through the holes around the rim). The types that just clip onto the edge of the bowl are cute, but ineffective at actually keeping the toilet clean.There are many products sold that go in the tank which are effective at cleaning, however, they are harmful to the internal components and cause premature failure that can lead to leaks, and possibly property damage.The Fluidmaster system cleans effectively, without causing any damage to the toilet components. Its design is simple, yet genius. It consists of a small unit that connects onto the refill line, between the fill value and refill tube. The unit accepts a replaceable bleach cartridge and is completely sealed. When the toilet is flushed, water passes through the cleaning system, directly into the refill tube. This water passes through the flush holes and into the bowl, allowing the cleaning solution to be evenly distributed without any of the solution entering the tank.With this system clean water from the tank is used to flush, followed by the water with cleaning solution as the toilet refills.They claim that the bleach cartridges last approximately 3 months and I imagine that depends upon the amount of use. Unlike the bleach tablets you put directly in the tank which will continue to dissolve even without use (and thus the bleach content gets stronger and stronger), the Fluidmaster cartridges only get used when the toilet is flushed.This is by far the best cleaning system I've seen. It's simple, affordable, and effective. If you hate constantly scrubbing toilets, you may want to get this. We tried it in one of our toilets and it worked so well we bought three more. Oh, and if you're worried about remembering to change the cartridges, Fluidmaster has a website where you can sign up for reminders (and I'm sure they'll be more than happy to sell you the refills as well.) You can also get these on Amazon Subscribe and Save at a good price. That's what I did, so when they show up, I know it's time to change them.Also, as a side note, I did try buying chlorine tablets and using them instead of buying the replacement cartridges, as many others have done. While this option may be slightly less expensive, I've found that not to be a good option for several reasons. First, the chlorine smell is unbearable, even if I used only 1 tablet instead of two. Using bromine tablets would probably be better for that issue. Secondly, the chlorine tablets continue dissolving inside the cleaning system, even when the toilet is not used much. I had put 1 tablet in one of the toilets that we do not use much and after a week or so I flushed it and the smell was at toxic levels. I removed the cartridge to inspect and it had mostly dissolved and the fumes nearly killed me. The Fluidmaster refills do not seem to have this problem, as I've inspected all 4 of our toilets regularly while using them over the past year and find that those that are not used much stay intact, while those used more often dissolve faster. This is better as they remain effective for much longer in most of our toilets and I only have to replace the ones that are used more every 2-3 months. I'm not sure what's different about the tablets in the refill cartridges, but I've found it better to just buy them less often than trying to keep up with the chlorine tablets.I can say that our toilets do stay much cleaner using this system, so it has been worth the investment.

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 have been doing a great job of keeping the bowls clean in all of our toilets. The drop in tablets have been destroying our seals and this actually dispenses more to the bowl where it is needed.I did make a small modification to the dispenser so that a small amount of chlorinated water is dispensed into the tank to keep microbes down to a minimum. We are on well water, so there is no chlorination in our water supply. In my case, a small hole drilled into the outlet line, right before it is dispensed into the fill pipe, makes just a tiny stream into the tank.Also, but the blue tabs as it is easier to tell when it is time for new cartridges.

These fit and were easy to install. They help keep the dirt ring from our water from forming. There is a decided chlorine smell sometimes but most times is not noticeable. Reduced the amount of bowl cleaning due to not so clean water from our water supplier.

Bought two one for upstairs and one downstairs all the water runs though the tablets and helps keep the toilet clean.This is not a replacement for cleaning your toilet, you still need to clean it.

We are on a well but still prefer the one with bleach since there is only twp of us.

Too expensive - specially the refill, but works like wonder. This is not suitable for use in Indian Flush system as the overflow pipe is usually not available and I had to modify the same to get it working.

works oerfect for my toilet bowl

Product is good. Hate the smell.
