Questions & Answers

Why does my toilet run for 3-5 seconds every 5 minutes or so even when I don't flush

Asked by: Steve
There is another issue which is not mentioned by any one and surprisingly it appears to the issue with many ball floats when the screw holding up the float gets rusty. 1) If the water supply is stopped to the tank and the tank level does not drop. Then it would not be a flapper problem. 2) If the water supply is on and water level goes up and overflows thru the central spout and down into the bowl, then it is the problem with the fill tube and the float?

Did I ruin the fill valve by moving the lock ring?

If I pushed up the lock ring and pulled the threaded shank completely out of the valve body but then reinstalled it and re-seated the lock ring, can I expect it to be OK or did I damage anything?
Asked by: Karen
Should be fine, because: I wasn't able to adjust the height by turning (un/screwing) the two parts as instructed, so I took it back to HD. The clerk did exactly as you did; just yanked the two tubes apart. We reassembled it, adjusted to correct height, installed it, and after 3 yrs, no problems.

How tall is the valve. Many tanks are tall and the "universal toilet fill valve" is so short that it fills one half tank and "thus it is a half flush"!!!

Will this work on a discontinued Kohler two piece toilet that is over twenty years old? There seems to be no replacement parts for it. Model K3397-0
Asked by: Rey
Vahandyman is spot-on. The toilet model you stated ( K3397-0 San Raphael ) is a Kohler one-piece lowboy style with unique features (rim flush). The Fluidmaster is not designed for this application. The kit mentioned by vanhandyman is the way to go.

I can do it blindfolded now :) I always have at least 1-2 spare ones in my tool bag. 1. Shut off the water supply behind the toilet. (you may run into a problem here since a lot of shut off valves don't work when you need it to. If so, shut it off at the main water line) 2. flush the toilet 3. unscrew the water supply line going into the toilet(if the line looks pretty old, now is a good time to change it out) 4. optional- shop vac any remaining water out of the tank, or use a couple towels to drain it 5. loosen and remove the nut holding the old fill valve in place. clean under and above the exposed hole 6. insert new fill valve with rubber gasket inserted on top. 7. tighten at the bottom and reattach the supply lines, turn on water supply, adjust the black stick on the fill valve for water level(it's pretty cheap feeling so go easy on it)

I bought the fill valve to replace another one that had been sticking and would not open to refill the tank after a flush. I was anticipating a day-long operation with leaking fittings (I hate doing plumbing) but this was amazingly easy. I simple released a slip ring, yanked the old valve off and pushed the new valve onto the pipe in its place. Done if five minutes. Fluidmaster should get kudos for making product that could be easily installed by someone with no training.

I had one of these in this toilet and it had a small, barely noticeable leak, so I thought I’d just change the valve seal! Wrong! I had to change the whole thing out, small crack had happened to the original that wasn’t visible to the eye. 2nd trip to Home Depot to get the complete unit, had the complete unit in my hand the 1st trip, only to tell myself that only needed the seal. LOL.

Only thing that kept me from giving it 5 stars is that the installation instructions were not clear for me (a single female). Therefore, I put a washer on upside down and had a leak overnight. I was able to figure out the problem and correct it before any real damage was done. Happy to prove to myself I can make a repair without paying a plumber a fortune for something so simple!

Hold the flush lever down till most of the water is gone in the tank. Use a towel or sponge to soak up the rest of the water, Disconnect the supple line to the valve. Remove the nut holding the valve to the tank. Reverse the steps. Easy to adjust the height of the water in the tank with the float too.

I only needed to replace the $4 cap but have retained the items for spare parts for the other toilets in the house. Relatively easy yo separate the cap after a quick check with YouTube video on the subject. I have used this type product for years on personal and rent houses. Durable and easy to install, adjust, and maintain.

The positives are its inexpensive and easy to install as long as you don't have a problem with shutting off the water to the tank. I only rated it average because in my experience these valves rarely make it more than 2 or 3 years. By then its not worth the trouble of trying to find out how to execute the 5 year warrantee.
