Customer Reviews for Fluidmaster 400A Universal Toilet Fill Dual Flush Valve (Contractor 3-Pack)

It works as designed

I use them cause they’re easy to install and cheaper than a plumber

I work in a condo building & this product works when multiple units need repair

Very easy to replace!

Standard builder's grade valves. Easy to install and replace (DIY). Cheap enough to replace when malfunctioning, so I always keep a spare handy. Do not recommend repairing - just put in a new one. Mine usually last 5-10 years with soft water.

Easy install. Nice to have the option to buy contractors pack.

Even though it was a simple product to install it should have more concise instructions.

Works good, but seems slow to refill the tank.

This item worked perfectly to remedy the issue we had on both toilets

I ordered these to have a spare in case I need one.

Easy install and easy adjustment for fill level
