does not fit standard uk cisterns all threads are too large do not buy this product for uk!!!

Over time, calcium and other particles will build up on both the fill and flush valves. My toilets were filling slowly, and simply replacing the flappers no longer stopped the flush valve leaks, so it was time to replace all of the toilet tank's innards. A leaking flush valve causes water to leak from the tank into the bowl between flushes, which then causes the fill valve to replenish the lost water periodically, which wastes a considerable amount of water. Installation is normally simple, except that my Sterling brand toilets have 3 bolts holding the tank to the toilet as well as an integrated bolt and gasket arrangement between the tank and bowl. In my case, I had to re-use the existing bolts as well as the existing rubber gasket. For "normal" toilets, you use the 2 bolts, washers and gasket in this kit when replacing the flush valve and re-attaching the tank to the bowl. Replacing the fill valve with the one in this kit is simple and takes just a couple of minutes, and can usually be done with no tools. My toilet tanks now refill quickly, and the flush valves no longer leak water into the tank.

The 2” refers to the inside of the valve. Outside much wider and did not fit the cistern.

Muy buena calidad, de materiales, y super fácil de instalar,

This kit worked pretty well for fixing the toilet without needing to buy separate parts. Everything needed was included and the instructions were simple enough to follow. It stopped the constant running issue right away after installing it. The parts feel decent quality and fit properly in the tank. It also saved money compared to calling a plumber for a simple repair. Only thing is installation can take a little patience if you’ve never replaced toilet parts before. Overall though it’s a good value and works as expected.

My toilet began to run almost constantly, the tank refilling every 3-4 minutes. I had tried installing individual components which I suspected was the cause with little luck. Instead of buying a new toilet, I decided to rebuilt my existing one since new good-quality toilets are expensive and mine was in excellent condition. I did a lot of research before buying this set and learned that quite a few new toilet manufacturers use all Fluidmaster components; this is quite a compliment. The instructions are very thorough, clear and written in easy-to-understand language (in Spanish too). That isn’t true of some other brands. Note that it is important to thoroughly clean off scale, rust, and gunk from all areas of the tank and toilet which are going to have rubber gaskets seated on them, otherwise you will have leaks or poor functioning of your new “guts”. After installation, my toilet worked perfectly, even better than a new toilet since it is an older model which uses more water than the new models. NOTE: you MUST determine either the tank capacity or the year of manufacture in order to choose the correct Fluidmaster model. This one is for older model toilets, specifically for 1.6 and larger gallons per flush toilets, and with a 2″ flush valve as mine does: it dates to 1999. The flush valve hole determines this size. The newer models use much smaller amounts of water and will not flush completely. I highly recommend replacing ALL components inside the tank, as the gaskets, rubber, plastic and vinyl parts become brittle or gummy due to the corrosive effect of the chlorine which is added to municipal water supplies. In my tank, I discovered that the plastic tube on my flush valve had become brittle and cracked and was leaking, and the flush valve gasket (between the tank and toilet) had turned to a gooey mush and was another source of leaks. ALL of the other gaskets were suspect which is why it is best to replace the whole shebang at once. Check the Fluidmaster website for particulars of each model repair kit before you choose one. BTW, Fluidmaster suggests changing the guts of your toilet every 5 years due to deterioration of the components. While I personally think most folks will get > 5 years out of the tank guts, it is smart to keep a sharp eye on it.
