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

What an easy hook up. Took me 3 minutes per toilet to install these units. They wok perfectly when you flush the toilet. Allows the bleach to coat and sit in the bowl to help with cleaning and sanitizing. I used my hot tub chlorine tests strips to measure the amount of chlorine in the bowl after a flush and it read 3 PPM’s which is ideal for sanitizing. Some people state in the reviews it had a huge chlorine sent. Thats really dependent upon your nose. lol. I didn’t notice a severe smell of chlorine. It was subtle Love these units. Keeps the bowl fresh. I still do a deep clean as needed and for sure once a week but these help between cleanings. Love them.

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!

Working pretty good

I installed 4 of these this past June in my home and my parents' home. These are replacements for older Kaboom toilet cleaning system that started to leak (again) The design and the quality of the plastic on this Fluidmaster system is MUCH better than what I had been using. I did get 4 months use on one of the toilets, another is still going on 4 months into the 5th month so how long they last will depend on how many times you flush them and maybe how many gallons of water each flush uses too. Mine are 1.6GPF American Standard and there are 2 people in the home. If you have more people, they may not last as long, but they are still worth it though!! I did not take a brush to either of my toilets once during this time. I did not have to as they were CLEAN and I have a water softener which helps too. You DO have to scrub your toilets clean before using this. This system will MAINTAIN a clean toilet. Do not put this into a dirty toilet and expect it to clean the dirty toilet for you. Being one of my cartridges is done, I will attempt to take it apart and 'refill' it myself with my own bromine tablets. IMO, it's worth a try being I already have a spent cartridge and some bromine. Updates on that coming soon. If my own attempt at rigging a refill does not work out, Fluidmaster refills are cheap enough for a 2 pack which would last 3+ more months in my home. For my father's toilets (Mansfield) that are 1.6gpf, one cartridge almost lasts him 1 month. BUT, his toilets use way more water than they state, they are filthy, inefficient and impossible to clean toilets that are poorly designed and should be banned from American households. There are 2 people in his household so the reason they don't last long there is because of the crappy toilets. Update on me opening these cartridges.... I was able to, but I can't find bromine the correct size to fit inside. Clorox is too big. I don't mind buying the refills for my home, but for my dad's inefficient and poorly designed Mansfield toilets, we have him on subscribe and save with monthly deliveries. It does not bother him to spend $10ish a month to keep his water wasters.

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.

Muy buen producto facil de instalar

This kit is not readily available in Canada, but fortunately Amazon vendors sell it at a reasonable markup (considering it is shipped from the USA). It's an excellent automatic toilet cleaning system as it does not damage the rubber seals in your tank with chlorine (my Toto tank actually has an explicit warning stating not to use chlorine cleaners). It "splices" inline with fill hose so that the bleach solution bypasses the tank altogether (via the overflow tube) and fills your bowl after each flush while the tank is refilling. Installation is very simple, and the bracket is plastic so you can trim it to fit your tank if necessary. Ensure your tank lid seats fully to reduce flushing and filling noise. It functions as intended but I cannot assess effectiveness yet - I am hoping it either stops or slows the growth of the pink bacteria ring. There is a faint chlorine smell when you first lift the lid, but nothing too offensive IMO. The water level in my bowl has not changed. 3 month update: True to their word, the original chlorine tablets have completely dissolved after 3 months. This is on the primary toilet for two adults. I have not had to clean my toilet for the same period, and there is no pink bacterial growth whatsoever. This is an excellent upgrade as I was cleaning our toilet every 2-3 weeks due to the ring of pink bacteria. Refills: The replacement cartridges are not readily available in Canada but you can replace the tablets yourself with 1" tablets. To gain access, you can pry the bottom cap up off the cartridge with a folding utility knife and tap or pull the cap off. The original cartridge contains three 26x16mm (ie 1”) tablets and each weighs 11-12g (~34g net weight). The tablets contain DCDMH, boric acid and chlorine per the package label. However, the SDS for the refills indicate that the tablets used to contain 7-13% chlorine (89415-87-2), 40-70% BCDMH (16079-88-2) and 15-40% DCDMH (118-52-5). Fluidmaster likely originally used this chlorine-bromine blend because pure chlorine may be too acidic and/or odorous, but switched to chlorine only tablets due to costs? Regardless, for cheap refills, I purchased Azur Spa bromo tabs (~$50/1.8kg or 60c each). These tablets are 30x18mm (1.2") and weigh 20g. To fit these into the cleaner, cut the "lid" off the cartridge, remove the foam piece, and drop three tablets directly into the holder (instead of refilling the cartridge) - see photos. You now have 60g of bromine (compared to 34g of chlorine) that should last longer, be less acidic and smell less. Flow has not been restricted and there does not appear to be any downsides to this, but I will provide an update if that changes. Hope this helps.

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.

Great product, keeps the toilet clean a longer period of time. However, the bleach refills are very expensive, twice the price, compared to the blue refills. And currently only one seller has them.
