One of the most heard complains plumbers receive for toilets are, “My toilet water rises then slowly drains,” -which is an awfully painful thing to hear, considering it’s very easy to fix.

One of the other complains that are seldom heard also include problems with toilets having high water. Hence, we’ve prepared this article solely focusing on the two most commonly heard problems.

You’ll need very basic utensils to fix the minor issues. They’re considerably easy and very affordable as well. Thus, we can assure you there’s no need to panic!

Toilet Water Rises then Slowly Drains

Fixing a Slow Flush

The flush handle is relaxed if a toilet works well enough that water will run from the tank to the bowl and down the waste line. Water must hurry fast, and this flow causes the flush in the vessel.

Flush system issues, limited tank-bowl flow, waste line blockage, or even poor ventilation can lead to slow flow. You don’t have to be too organized when troubleshooting slow flushing; you can start with fast solutions.

To start the procedure, plunge the toilet with a plunger inside the opening. Plunging is quick, and a plunger will clear it if a partial waste blocking causes sluggish flushing. Remove blockade with a toilet auger until the toilet runs, irrespective of any blocking signals, such as backup.

Listen to the gurgling noises from surrounding sinks as you go to the bathroom. If you notice these noises, it implies that there is not enough air in the waste lines to enable water to move freely. Remove the scrap on the roof from the openings.

Sprinkle it with the garden hose water until it is empty. Use a sewer drill, which is longer than a toilet auger, to clear the air while sewage is secured if you should borrow one.

To ensure that the water flows naturally between the tank and the bowl:

  1. Check the toilet facility.
  2. Switch on the flush valve to start.
  3. Open the tank and keep an eye on the flapper while it is flushing.

It can go up to nearly vertical height. Otherwise, it would most probably not enable sufficient water to drain from the tank for proper flushing. Reduce the chain length connecting it to the flush grip.

Take notice of the water level of the tank. If the tank is full, it should be about one inch under the overflow vent top. Whether it’s fewer, there’s probably not enough water to flush fully. Adjust the float and keep the filling valve open for a long time.

The water inlet holes on the bottom of the bowl may be cleaned using an upgraded paper clip. These cracks are broken by mineral particles that are more likely to occur if the toilet is aged or has rough water.

You’ll be specifically needing plungers, toilet augers, garden hoses, sewer augers, and paper clips for completing the process thoroughly.

Important Things to Remember

If the toilet continues to be slow despite these moves, something like a plastic or metal toy may be tied into the P-trap and not recovered with an auger. To clear the toilet, definitely pull it.

Roots may have spread through sewers if you have trees rising in your house and found slow flushing over time. In certain circumstances, medicinal help is needed to extract them. If you have more debris, you can clean it up with chemical cleaners.

How to Fix a Toilet with High Water

High water in a bowl or tank has in each situation various solutions. A mismatched float generates high tank water, while a split flapper or waste block will produce high cup water. You see the valve fill cycling on and off or turning, whether you had problems with the float or flapper.

However, we’ll be adjusting all sorts of issues down below:

Float adjustment

Float is an easy procedure, and corrections are just as quick. If the ballcock has a float on the end of a metal rod, lengthen to put higher pressure on the fill valve, turn it off faster and reduce the tank’s water volume.

Turning the ball in the other direction achieves this. The valve is connected by an elastic rod if the float bends over the valve tube. Ensure to adjust the water level as required, or else it will overflow again.

Flapper Service

The rubber bottle is intended to hold water in the tank before it flushes. It will splash water into the bowl when it pulls out, or the holding chain is too close. As a consequence, the amount of water in the bowl increases to the height of the internal P-trap outlet.

It’s not hard to extend the chain; don’t go too far, or the toilet isn’t properly flushed. The only choice is to replace the flapper since it must be serviced. New pads are cheap and simple to remove.

Cleaning Debris

The bowl level will climb over the P-trap outlet with a blockage in the trash line, causing the toilet to leak. The plunger has been developed for such scenarios. Often aggressive plunge loosens blockages enough to clean them.

In occasional times, a plastic pad or tampon will reach the waste line. Typically, a snake or bath auger removes it. You feed the serpent directly into the bowl and crank it until it stops.


When the bowl water level is too high, a combination of blockage and a worn flapper can occur. In bowl water and the tank refilling tone, a flapper issue is normally detected by rips.

However, if the leak is slow enough, these signs may be too slight to be seen, and the only hint of an issue could be a higher cup.

Putting food coloring in the tank and not flushing it for several hours is an easy means of catching a leak. It is time to serve the flapper if the color of the platform is the same.


Hence, we hope by now you know everything there is to know about unplugging your flush and making the regular flush speeding come back.

It’s always recommended to get your flushes checked by professionals if you find that they’re still having malfunctions of some sort. Therefore, till the next time, happy flushing!
