Pros

  • β€’Installation is reportedly easy and straightforward, taking about 30 minutes for a DIY enthusiast.
  • β€’Compatible with Kohler Highline Arc models and works well with previously used Fluidmaster valves.
  • β€’Offers adjustable valves for both tank and bowl water levels, enhancing flush performance.
  • β€’Users with a history of Fluidmaster products appreciate their innovation and product evolution.
  • β€’Some users find it a satisfactory and recommended upgrade, solving previous flushing issues effectively.

Cons

  • β€’The fill valve is considered noisy and slow, contradicting its marketing as high performance.
  • β€’Installation instructions are unclear and confusing, particularly for users without plumbing experience.
  • β€’Some users experienced significant water spraying issues during testing, needing additional adjustments.
  • β€’The quality of materials is perceived as cheaper and flimsier compared to older models.
  • β€’Some experienced frustration due to installation difficulties and poor performance, resulting in returns.

Bottom Line

The Fluidmaster PerforMAX High Performance Fill Valve 400H-002-P10 is praised for its ease of installation and compatibility with various toilet models, making it a convenient option for those familiar with Fluidmaster products. However, the inconsistent performance, noisy operation, and confusing installation instructions could be off-putting for some users, particularly those new to plumbing repairs. Shoppers may wish to consider older Fluidmaster models for quieter operation and potentially better performance.
