Questions & Answers

Why does it take so long for the tank to refill after flushing?

the water seems to be filling slowly compared to the original fill valve. what can be done for it to fill faster than almost 5 minutes? by the way my brother installed it.
Asked by: TG
Make sure the valve on the wall controlling water to the tank itself is all the way open. That is usually the culprit. Otherwise it might be dirt in the line or Toilet Fill Valve.

You must have not adjusted the 'Roller Clamp' properly. See Step 6 of the instruction.

PerforMAX Max Performance Toilet Fill Valve is rated 4.4 out of 5 by 758.

It was easy to install and worked well at first, but about a month ago it started leaking nonstop. I checked it out, tried cleaning and adjusting it, and nothing worked. At least for me, it just didn't last.

Rated 5 out of 5 by from Easy Installation, Quiet Refill, Powerful Flow I am really happy with my choice to get a Fluidmaster High Performance Toilet Fill Valve. It is made with top quality materials and built to last for years of trouble free performance. I got my new fill valve after my old toilet fill valve was starting to malfunction and was not refilling my tank. My new Fluidmaster PerforMAX Toilet Fill Valve was super easy to install with its easy twist height adjustment to fit my standard 1.6 gallon toilet, then simply connecting the shank to the tank by securing the shank washer between the locknut and hand tighten until secure, be sure to leak test, then connect the refill tube to the overflow pipe and adjust the roller clamp to your desired water savings level. Detailed instructions with pictures are included, along with a toll free customer support number available M-F 5:30 a.m. to 5 p.m. PST. Fluidmaster gives you a 7 year warranty. I highly recommend the Fluidmaster PerforMAX Toilet Fill Valve. [This review was collected as part of a promotion.]

Rated 2 out of 5 by from Doesn't last Instal was simple. I have had the product roughly one year, and the fill value does not completely shut off any more. It is completely open (like it should be) to fill the tank. Then, when the float shuts off the water, it continues to drip, drip, drip, for over 30 seconds. I have checked the fill valve, and tried flushing out the debris, but it still drips, drips, drip.

Just a few points: 1. Make sure you get the connecting hose with a length which doesn't put strain on the fitting to the toilet bowl. If the connecting hose is too long, it will bend and as result there's going to be stress on the toilet bowl fitting. For example: I had a 12 inch hose originally and it broke the bowl fitting while I was away resulting in a flooded house. When I replaced the fill valve I replaced the 12 inch hose with a 9 inch hose. 2. Adjust the overall length so that the top of the fill valve doesn't contact the bowl lid. 3. Then adjust the float to lower/higher the bowl water level.

Rated 5 out of 5 by from Easy Installation, Quiet Refill, and Saves Water! If you are looking for a durable well-made new toilet fill valve that's quiet when filling up the tank, easy to install, and saves water, then the Fluidmaster PerforMAX 400AH is the perfect solution, especially for newer toilets made after 1994 with 1.28 gallons per flush. Installation is a breeze: just turn off your water supply at the toilet valve, disconnect the nut from the toilet tank, remove your old toilet fill valve, install the new fill valve using the enclosed shank washer and locknut, attach the water supply, then attach the enclosed refill clip to the overflow pipe, adjust the water tank level and water-saving. The Fluidmaster PerforMAX 400AH comes with a 7 year warranty and is designed and engineered in the USA. A high quality product designed and built to provide years of trouble free toilet fill valve performance. I highly recommend the Fluidmaster PerforMAX 400AH.

Rated 4 out of 5 by from Works swell I actually want to give it 4.5 stars. The Performax came pre-installed in my Kohler toilet. I have had it about two years, no major problems and it fills pretty quickly. I recently had one minor issue when the toilet started running a long time before shutting off. I couldn't find the solution online so I called in. Great, patient, knowledgeable support/help from FluidMaster. I was talked through how to make one minor adjustment (no tools required) and in less than 10 minutes things were working perfectly.
