Toilet Not Filling All The Way

Hi All:
One of my toilets has recently begun to not fill all the way after flushing. The water level in the tank is up to the water level line, and if you hold the handle down for a bit after flushing, it will fill the bowl all the way. I replaced the flapper valve, no change. The flush volume seems adequate, just doesn't want to fill all the way. Could this be a result of a restriction in the pipe somewhere?

Thanks!

Scott

There is a tube that goes from the valve to the overflow pipe if that is broken or restricted it won't fill.

You might put up a picture so people can see what kind you have.

I had exactly this problem. Replacing the flapper and fill valves didn't make any difference. Everything in the tank portion looked fine. I suspected scale buildup in the rinse holes.

I never got a chance to try this before I replaced all the toilets (we re-did the floors, so while the toilets were removed, we took the opportunity to replace them).

This.

The tube from the valve to the overflow pipe seems OK, took it out and ran water through it, seems good.

What I do notice, is that water streams out from the upper part of the valve assembly to fill the tank, is that the way it's supposed to fill? Or should it flow into the overflow pipe via the tube from the valve? There seems to be a hole underneath the top portion of the valve for water to flow, and that's how the tank is filling. The tank fills fine.

I did run some vinegar into the overflow tube the other day to see if the refill holes were blocked, no change.

Vinegar won't do anything except remove some stains.

Short of using muriatic (Hydrochloric) acid, you'll have to do the coat-hanger trick to clear out those holes.

Just checked the refill holes, they look clean as a whistle. The flushing flow seems normal, just the refill that isn't right.

Show us from this picture, where the water is coming out for refilling the tank

Photo of water flow from valve, I have a hunch this isn't correct?

That isn't as important as knowing whether or not you have water coming out that white plastic hose. Did you pull that out of the tube and see how much that flows?

Is that a stream of water at about 4 o'clock? If so you are correct the valve is leaking so water is not going through the refill tube at the top of the overflow pipe.

Valve may be fixable but most likely not - replacements are cheap.

Well, there should be another tube (hard tube) going down into the tank itself.

It looks like you have a crack in the assembly, letting out too much water into the tank and not enough into the bowl (Rubber tube).

The whole assembly is like 15$ at home depot.

There are a number of different fill valve designs but they all US models tend to have in common two outlets. The main volume of water from the fill valve outputs directly into the tank to refill it. At the same time some amount of water is output through a tube. That tube needs to be inserted into the overflow tube/pipe to fill the toilet bowl with fresh water.

You mention that there is water coming out of the tube from the fill valve is it the right amount ? Try to compare it with a working toilet to see if perhaps the flow is too low.
On some older (good quality) fill valves I have seen adjustments to set the amount of water going into the overflow tube/pipe (or more specifically the ratio between the two amounts). None of the replacement fill valves I have installed in the last decade had that feature but if yours does you might want to temporarily fully open the flow adjustment to perhaps flush out any obstructing particles.

An easy way to check if the overflow tube/pipe is draining into your toilet bowl properly is to pour some water into it and see whether the toilet bowl fills that way. It would be very unusual if that didn't work.

Edit: looks like I was too slow in responding. It appears your fill valve is putting too much water into the tank and therefore not giving enough time for the water through the overflow tube to refill the bowl. I suggest replacing the fill valve. The brand I used most recently was Korky which is made in the US. The leak / stuck flush valve features of the Korky Waterwise fill valve do look gimmicky but do work well.

Yes, your fill valve is broken. I would replace it with a Fluidmaster 400A, but some folks here prefer other products.

That is a stream of water at about 4 o'clock. There seems to be a fairly decent stream of water from the rubber tube into the overflow tube.

Seems like the valve is faulty I guess?

It's not like there is NO water going into the bowl. The problem is that there isn't enough water going into the overflow tube before the tank is full. So faulty valve, get a new one (15$)

OK guys, thanks for all the help, will replace the valve.

Thanks again!!

I fought a similar problem.

If as you said, you can hold down the lever for like 3 sec. after the flush starts and it fills ok, ( even releasing the lever before the fill finishes ) then your flapper may be closing prematurely. My actual lever arm was an aftermarket. An old plumber told me to order the correct lever arm for my model toilet from Kohler. It fixed the problem since early this year.

Yes, if I hold the lever for a few seconds the water level in the bowl is fine. I did see at Lowes they had a flapper with a foam float on the chain that delays the flapper from closing a bit.

Ok, just as long as it doesn't get tangled in the chain, chain is not too short, too long, etc. The Kohler brand exact replacement fixed me up. Wouldn't hurt to replace the flapper though too i suppose. Maybe i did that too, don't remember.

I think that foam float is only to keep the chain from possibly being stuck between the flapper and seal. I don't think it has anything to do with delaying the closure. At least that is the case for the ones I have seen, but does not mean you have not found something I have not seen.

Could be, on the package it had some directions with a diagram that showed if you slid the foam float up the chain it would allow more water (or vice versa) Didn't get it because it was a dollar more, but I might give it a shot, although I don't think that's my problem.

I think replace the valve if that doesn't fix it, look elsewhere. The shotgun method may fix the problem but you're never sure what the problem was.

Your fill valve is leaking badly. It may even self-destruct and start spraying water everywhere. Replace it. »www.fluidmaster.com/our-products···lve.html

Sheesh.

thats the best when that happens.
you go to flush it, the assembly breaks, then it looks like a waterfall from the sides of the tank pouring out everywhere

Aftermarket lever Arm. Designed to fit any number of toilets, and none of them right. The flapper falls too fast. It's proven by the fact that when you hold the lever for 2 seconds, it continues to fill and works properly. It took me a long time before i became convinced. Direct replacement from toilet manufacturer. :THUMBUP:
