Fluidmaster Toilet Flush Valves 400H-002-P10 Editorial Review

The Fluidmaster 400H-5003 Performax Universal Toilet Fill Valve with Tank and Bowl Water Control 2-Pack is an affordable and easy-to-install replacement option for most toilets, including top flush and popular brands like American Standard and Gerber. It features an adjustable knob for bowl water control and customizable refill rates for both tank and bowl. The valve has proven to handle high water pressure well and is quieter than standard models. However, there have been reports of quality issues, including leaks and loud noises, possibly due to manufacturing defects. The product includes only the fill valve parts and not a float ball flapper. The instructional booklet is very informative, and the customer service is available via phone, chat, and email for additional support.
