Actually, it's the flush valve that's not closing. The ball operates the valve. In some cases the valve needs to be replaced; in others, the ball has absorbed water and is unable to close the valve completely.

Toilet does not have good flush

The power of the flush has nothing to do with the fill valve. It has to do with the flapper. When the flapper is opened, the surge of water into the bowl is what causes the toilet to flush. If the flapper closes too quickly, it will take away from the powerful flush. Try to find the correct flapper for that type of toilet and stay away from the "universal" flappers.

After flushing, wather doesnt come up in bowl evan if ball close hole good.

These are designed with a very, very low water level - just covering the well at the bottom of the tank. It's part of the design. Our family has made a practice of flushing once beforehand to wet the surfaces before doing any major business on the toilet.

Water always running into bowl

This usually indicates one of two things: (1) a poorly seated flush valve ball, which can be easily adjustedor replaced, or (2) a flush handle chain that is too long and is getting caught between the flush valve ball and the seat, which is easily remedied by shortening the chain between the flush handle and the flush ball.

Toilet flushes fine but when the tank has filled it seems like the float ball keeps bobbing up and down letting more water or air into the tank. it will do this 5/6 times then quits. its almost like it is...

The ball float follows the tank water level, and repeated cycles of the float dropping and opening the fill valve would likely reflect a leak in the flush valve. You could try adjusting the float arm downward so that it will respond to a lower water level. Try turning off the supply valve, flushing it and listen for water leaking past the flush valve after it closes. If it does, replace the flapper or adjust the chain.

1 Answer

The flush valve does stay open long enough after flushing

Which style of flush valve do you have? If it is the dual-flush option (solids/liquids) I do not know how to adjust those. If you have a traditional style, then the flapper or ball is closing too soon. You need to adjust the guide arm (flush ball) higher or shorten the chain between the flapper and the handle. Adjust this carefully or you will have it fail to seat and the toilet will constantly run.

I hope this helps.

Poor flushing

Make sure the water level is the same in both tanks, so you know the water volume will be the same for both units when flushing. Next, hold the handle down for the full flush release to make sure the flapper (in the tank) is not closing too soon and cutting off the full water volume needed. Next, would be to get a tolet snake reamer (buy the cheapest one) and run it through the toilet bowl 3 or 4 times always turning clockwise while entering and while removing. If all this does not cure the problem, then you probably have a defective toilet outlet hole that was made too small when the toilet was formed. The outlet hole must be minimum 1 5/8 inch diameter (most are between
1 3/4 inch to 2 1/4 inch diam.) . This is an occassional industry problem; I have seen it several time over the many years. To confirm this, you need to remove the toilet and measure the hole, or get flush balls of 1 5/8 inch with 4 ft. string attached. If the ball flushes and takes all the string slack, then the hole is at least correct minimum size. If ball does not completely flush after 3 tries, then there is some obstruction or the hole is too small and toilet it therefore defective. Goodluck, Macgivor

Valve in dometic vt2500 toilet won't close

You might want to try and lubricate the rubber gasket with some silicone grease or plumbers grease. If that doesn't work, follow this link. I'm sure there is information for your toilet at the Dometic website.
