Question about Toto Toilets ST784S 12 Sedona Beige Clayton Toilet with Traditional SoftClo

1 Answer

Flush Toto less than year old. Following flush (which is not quiet), remains ru nning for extended period of time. Then, on many occasions, following running, toilet makes a "hissing" sound then it physically "vibrates/shakes" for a few seconds. (The ice maker also rattles during this process). I am afraid it may be jarring the bolts loose, or doing perminent damage.

It sounds to me as though its the ballvalve not shutting off properly & when it does shut off the noise you hear is a water hammer, and my guessing is you have a water meter with a back flow prevention valve fitted so when the ballvalve shuts off the pressure exerted on the valve cant go anywhere due to the back flow unit so the noise is the water reverberating through loose pipe-work, annoying but not damaging

Five year old Toto toilet has developed a very slow flush in the past few weeks. Plumber has found no clog in line and water from hose flows freely with no back up. We have two other similar Toto toilets...

This can happen if there is a hole (physical damage) inside the trap. Instead of the weight of the water during a flush causing it to drain right down suddenly and completely, it draws in air and loses the momentum. There could be a hole or a crack, which may be hard to find without removing the unit.

When I flush the toilet does flush fine but it makes a gasping sound as it tries to refill the tank. Eventually (after 5 minutes) the tank fills and the gasping stops.

new quality flush valves are inexpensive. suggest you buy a new one at a big box store (Lowe's e.g.) . easy to install, just follow the directions.....a Fluid Master or Gorkie should work fine...$25 or less, probably less.....
