Fluidmaster 400H Universal Toilet Fill Valve, High Performance, 2-Pack | 2X faster bowl refill, Quiet operation, Adjustable tank and bowl water levels, EZ-Twist 9–14 in. height

I recently installed the Fluidmaster 400H-5003 Performax Universal Toilet Fill Valve, and it worked great. My toilet was noisy and slow to refill, and this fixed both problems right away. The whole job took me about 20 minutes. But to be honest, most of that time was spent wrestling with the old valve stem. The lock nut on the original valve stem was corroded and took some real effort to remove (make sure you have a hammer and a slot-head screwdriver handy to break the old one). Once that was off, installing the new Fluidmaster assembly was quick and painless. The instructions were clear, and I didn’t need any special tools. After installation, the toilet filled much faster and ran noticeably quieter. I also appreciated being able to adjust the water levels in both the tank and the bowl to get the flush just right. It’s not completely silent while refilling, but the sound is much quieter than before and not a problem at all. Overall, this is a great product that’s easy to install and works exactly as expected. If your toilet’s making noise or slow to fill, this is a reliable and affordable fix.

Extremely easy to install arrived quickly after order and have no leaks in either water closet. This is a universal fit and adjustable for tank volume. Good value

Easy to install (15mins) Super quiet too! I love the flow adjustment feature.

I’ve had a toilet for 14 years that I couldn’t get it to flush without holding the handle for 5 seconds. I’ve changed out the guts of the toilet several times. The fluid master was the lucky one that fixed it. Works great and install easy.

Best bang for your buck. This is my favorite one whenever I have an issue with a toilet. it’s so easy to install and made of strong materials. I love it. it came with all of the required parts.

I hate plumbing with a passion, mainly because anything I touch it leaks or breaks lol the instructions were super easy to follow and shows pictures in case to really stress about installing. The product was also super easy to work with and does not take long at all to install. A little louder than my previous guts that were in the toilet but that also failed so as long as this product holds up it’s a 10/10 all day.

I replaced my long-serving prior generation Fluidmaster red-top valves with these. The ones I replaced were 18 years old in a Florida house with no filtering upstream of the valves, so they held up great! But all things come to an end, and when one started having a small leak in the top seal, I figured it was time to replace both toilets at once and be done with it for another however many years. These went in perfectly, replacing older Fluidmaster 450s. The seal on the bottom was easy and secure. Setting the fill height was a big improvement over the older model--I didn't have to worry about the works running into the side of the water closet. The next big improvement was being able to set the bowl fill level, which the old valves just filled to a fixed level. Installation was smooth, adjustment was easy. They're both flushing and closing securely a month later with no weird stuff like whining/whistling noises (as happens with other brands.) Highly recommended!

Easy install, good instructions, fixed all leaking and noisy problems.

Cuento con hidroneumático (30-50 psi) en mi hogar, tuve que cambiar mis antiguas válvulas con flotador porque provocaban vibraciones excesivas en las tuberías, estas vibraciones sólo desaparecían cuando cerraba casi por completo la válvula de control angular, lo cual no era conveniente porque tardaba hasta 15 minutos en llenarse el tanque. Encontré esta válvula después de buscar en foros de plomería, pedí esta versión de 2 válvulas, vienen en una caja de cartón perfectamente resguardadas. La válvula es de plástico (PP y POM) de gran calidad, aunque puede parecer frágil al tacto, es muy resistente una vez instalada. La instalación es bastante sencilla (solo ocupé una llave inglesa y el vídeo de instalación en la descripción de este producto). Adjunté un video de su funcionamiento luego de bajar la palanca completamente, llenó el tanque de mi inodoro (4.5 L) en menos de medio minuto y no hubo golpe de ariete (vibración de tubos). Aclaro lo siguiente, no es tan silenciosa como promociona la página de Fluidmaster (pero sí más silenciosa que una válvula de llenado con flotador Fleximatic, como el de la foto), sin embargo, sí llena el tanque bastante rápido y trabaja excelente con alta presión de agua (hasta 125 psi). El producto no es caro en comparación con lo que ofrece (llenado rápido, eficiente con alta presión de agua, silencioso si lo comparas con válvulas de flotador), además tiene garantía de 7 años. LO RECOMIENDO.

This has been a useful purchase and a welcome addition to everyday life. It is practical, easy to use, and does exactly what I hoped it would. I am very happy with it.

So easy to install and work great!!

Easy to replace and fixed my issue. Float and bowl adjustments were simple to use. Hope it doesn’t scale up as fast as the original.

Good quality and works perfectly ans easy to install.
