PerforMAX 3 in. Everything Toilet Repair Kit - Complete Fix

In this review the Fluidmaster PerforMAX 3 in. Everything Toilet repair kit is evaluated for homeowners and DIYers who need a complete replacement for a 3 in. flush valve toilet. The bottom line: this kit bundles a full set of parts plus tools and clear instructions so a single visit can replace the fill valve, flush valve components and tank-to-bowl gasket, making it the best one-box option for repairing most 3 in. flush valve toilets. It is particularly useful for someone who wants a straightforward install and to restore reliable flushing without measuring multiple parts.

Key Features

• All-in-one kit: Includes the PerforMAX fill valve, adjustable flush valve, adjustable 3 in. flapper and universal tank-to-bowl gasket so users replace the full flush assembly in one job.
• Easy to install: The kit ships with helpful install tools and clear instructions to make the job accessible to a homeowner with basic DIY skills.
• Adjustable height and dials: Fill valve height and adjustable tank and bowl dials allow customized water use and a better fit across different tank depths.
• Universal fit: The design fits most 3 in. flush valve toilets, including common brands like Toto and American Standard, reducing compatibility headaches.
• Durable hardware: Includes stainless steel hardware intended to resist corrosion and provide longer life than cheap replacements.
• Quiet, fast refill: The PerforMAX fill valve is designed to refill the tank quickly and quietly compared with older valves.

Who It's For

This kit is aimed at homeowners, landlords and maintenance staff who need a single, complete repair solution for a 3 in. flush valve toilet and prefer not to shop for separate parts. It is also a good choice for first-time DIYers because the included tools and instructions simplify the job and reduce the chance of missing a needed piece.

People who should look elsewhere include those with non-3 in. flush valves or toilets with unusual tank geometries that exceed the kit's adjustable range, and repair professionals who prefer sourcing specific aftermarket components rather than a universal kit.
