Fluidmaster 400A Toilet Tank Repair Valve

Installation was easier than I thought it would be. All hardware was included in the package and no tools are required. The instructions were good enough, although I couldn't raise the valve 3 inches above the drain or my lid wouldn't close (maybe 1.5 inches), and it still flushes just fine. The retaining nuts are the butterfly type, so they might be hard to remove if they get brittle. Total installation took around 5 minutes, and I hate plumbing.

Great

At first I was nervous it was going to fit. But I gave it a try because my toilet is a standard size and yeah it worked! Now I can just flush my toilet without it constantly running all day and all night. Also now my water bill won't be high anymore lol

DYI Replace Toilet Tank Valve

This was a replacement for a defective toilet tank valve. It was easy to install and completed in less than 30 minutes. Fluidmaster is a reliable brand I trust.
