Funciona excelente con alta presión de agua
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.

Solid Upgrade – Easy Install Once You Get the Old One Off
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.
