    Unhappy Water use - hissing G-Max Korky 528 fill valve - Quiet Fill

    I'll get to my high water use after the story.

    Last winter I installed a new Korky brand float valve in the basement toilet. It had a weird hissing sound but the water wasn't rising so I thought it was just annoying. In march I got tired of the annoying hissing, went and bought another one.....installed new one.......still hissed. Ok, I'll live with it.

    Around July 2009 my water usage started to climb. Usual use for the three of us was 3,500 / sometimes 4,000. The August water invoice showed 6,000 gallons. Ok, maybe my son took too many long showers.

    Each month the usage has increased. Last invoice was 10,000 gallons...yikes. This invoice showed 12,000 gallons. What is going on?

    So yesterday I started the search. Shut off the supply to the house, checked the meter, meter shows no flow to home. Good - no leaks outside.

    Turned the house main back on / checked meter, shows water flow. Hm?

    Went in and turned water off to the basement toilet with the hissing Korky valve / checked meter, meter shows no flow.

    Ok, that is weird because the water level is right on the line. Some food coloring in the tqank was in order. Waited, waited, waited, several hourse passed. No coloring in the bowel.

    So maybe the new flapper valve is leaking. Turned off the valve to the toilet. Let the thing sit all night. In the morning the water is still right on the line.

    For me to be using an extra 7,000 gallons a month from a leaking flapper valve, that tank should have been empty.

    So the hissing of the Korky fill valve could just be air in the lines. Could the movement of the air through the lines cause the little meter dial to spin and therefore cause the meter numbers to move.

    This is strange and I'm no newbie to this stuff. I've worked on maintenance crews, albeit that was 40 years ago but I am still mechanically inclined.

    Have I paid several hundred dollars for air?

    But where is the water going? It isn't coming out the tube, it isn't going into the tank, the flapper valve isn't leaking. Weird that both Korky fill valves made the same noise.

    Thanks for the head up on a replacement.

    For the amount it has cost for extra water we could have bought a brand new, eloquent fixture.

    My guess is the leaking valve is sending the water out the bowl refill tube. That would totaly bypass the tank and your food coloring.

    Default hissing

    The hissing sound is probably NOT coming from the toilet, that is just where you hear it. The sound may be a cracked pipe under the floor and the sound is being transmitted to the toilet where it is amplified so you hear it.

    Pulled the tube and let it run into the tank and not the refill tube.
    It stopped running when the tanks fill line was reached. Let it sit for a while, came back and the tank water had not risen one bit.

    Put the tube back into the refill.

    For some odd reason, the hissing is gone. I did make one more adjustment downward on the Korky. It still fills to the line on the tank but there is no hissing.

    Kind of makes me long for the days when you just had the floating ball to adjust.

    Crud can cause the seal on any toilet to leak a little. Sometimes it will flush away on its own, sometimes you have to manually clean it off, and sometimes, you just need to replace the cap seal (this works for the Korky Quietfill). The cap seal is available at Lowes for less than $3, so not a bad thing to have sitting around for the time when it does need to be replaced. The flapper valves don't last forever, either, so I like to keep one of those around as well.

    Question Toto G-Max Flushing System Filling Problem (Water Re-Filling)

    Hi All, we have a couple of of 3-4 year old Toto toilets that are exhibiting the following flushing system problems:

    1) An abnormal start/stop filling process
    2) They keep trying to fill even after they're at the stopping point

    So basically, as soon as you flush, the flushing sytem (g-max) starts the filling process, but instead of the usual constant fill then stop, it first starts to fill for a couple of seconds, then stops for a second, then starts to fill again then stops again and so on. When it gets to the point where it should stop filling (overflow hole), it keeps going with the stop/start fill routine for another 30 seconds on one of the toilets, but on the other toilet, it can sometimes go on like this for minutes (sometimes we even have to flush again to get it to stop).

    I made sure that the drain plug is resting over the drain hole nice and firm. I even pushed down on it while it was doing the fill/stop routine to see if it would make it stop, but it made no difference, it still kept trying to fill even though the water level was at about where it should stop.

    Does the flushing system need replacing? Is there something clogged? A broken seal somewhere? Any help/tips would be greatly appreciated.

    Thanks,

    Miguel

    I would pick up an assembly cap at Lowes Hardware and replace it.
    $2.47 near the Korky parts in the plumbing section.
    No tools, and less then a minute to replace.

    Woohooooo....the fill valve replacement caps did the trick. The washers on both caps were warped. Thanks again for the help Terry!!!!!

    Default Toto Supreme not always filling water with tank

    Long time lurker, first time poster.

    I picked up the Supreme, and it is a god send compared to the "Wellworth". However, there does seem to be some problem filling the tank with water periodically. I remove the lid and give the inlet valve a jiggle and it starts to fill the tank for the next flush. I don't see any room for adjustments. Any thoughts on what is required for a permanent fix?

    If the valve is sticking, it may need cleaning or a cap replacement.

    Default Korky 528 question

    I installed a korky 528 anti-siphon float valve over a year ago and have had no problems up until now. There is a slow leak somewhere, and I can hear a squeeling soud as the pressure builds within the valve and a slow leak is occuring slowly filling the tank. Is there a remedy to fix this problem that has occured out of nowhere, or do I need to get another replacement kit? Thanks in advance for the info.
