Toilet Flushes But Poop Stays

Many people complain that poop gets stuck or floats in the toilet bowl after flushing. It is an unpleasant situation and creates a smell in the bathroom.

The toilet flushes, but poop stays in it because of clogging, consistency, and hardness of poop, slow flushing, low flow toilets, low water level in tanks, damaged sewer lines, blocked toilet inlet hoses, and water tank issues.

Removing them as soon as possible is necessary because it is frustrating and causes unsanitary conditions. Use different cleaning agents and tools to remove them because it compromises the hygienic conditions.

Causes Solutions
Clogging Unclog drains with plunger equipment
Consistency of poop Add bio enzyme liquid in drains
Hard poop Dissolve hard poop with vinegar and baking soda
Slow flushing Use cleaning agents
Low flow toilets Prefer to install high flow toilets
Damaged sewer lines Pour a mixture of baking soda and vinegar
Blocked toilet inlet holes Add warm vinegar to the overflow valve
The issue with a water tank Replace chain or flapper seal


The clogged toilet drains cause difficulty in the movement of poop. These cannot move forward when drains are blocked with different particles that are non-dissolvable.

The clogging issue comes from poor cleaning and maintenance of the toilet drains. The blockage comes from waste tissues and baby wipes that cannot move forward.

Toilet papers are non-flushable items that can get stuck in the traps of the drain lines. Moreover, hair and foreign particles also block the drain and cause difficulty in flushing and movement of poop.

You should limit the use of toilet paper. Use the trashcan to put waste tissues in them rather than flushing them in the drain.

You can also use the plunger and auger equipment to remove the clogged tissue and other particles.

Consistency of poop

The consistency of poop depends on the variety of diets and eating habits. For example, a low intake of fibers and a high intake of fats leads to thick and sticky residues that can stick to the toilet bowls and are difficult to pass through.

In addition, the issue also comes due to a low intake of water and higher consumption of greasy food and soda drinks. It becomes difficult for you to clean the toilet bowl after flushing the tank multiple times.

Sometimes these can also float in the bowl due to entrapped gas in the stool. You can use the bio enzymes liquid.

These are easily available in stores, and enzymes present in them help soften and make them easy to flushable.

Hard poop

Many times, the stool cannot pass into the sewer lines after flushing the water tank of the toilets. The issue comes due to the bulkiness and hard texture.

These are hard and stick on the bowl’s surface and become difficult to move with water. Water pressure is not enough for their movement.

The issue comes when you consume excessive amounts of fast food and greasy and fried items. Poor eating patterns in a daily routine can affect your digestive system and the consistency of your stools.

You can dissolve the hard poop that remains in the toilets by using a mixture of baking soda and vinegar. These are helpful in breakdown the organic molecules and their forward movement into the sewer system.

Slow flushing

Many people complain that stool remains in the toilet after pressing the water tank’s handle. It shows that flushing water is not enough to move hard poop.

The slow water movement occurs due to faulty components of the water tank. In addition, clogged drains also slow down the flushing procedure.

Sometimes the obstructed pipes also lead to slow flushing of water. These are not clogged with the tissue of other foreign particles but have narrow diameters for water movement through them.

Check the water level in the tank. Use cleaning detergents to remove the residues from the obstructed drain pipes.

Low flow toilets

Low-flow toilets are modern ones specially designed to limit water flow. Many people install them in their bathrooms because they reduce water waste in flushing.

It has a specific design that is different from the traditional toilets for quick movement of stools without using excessive water.

Many times, these cannot remove the stools from the bowl because of the low pressure of water. People face issues in these toilets because of low water pressure during flushing.

The poop remains in the bowl because of limited water pressure. You should add high-flush toilets.

They provide enough amount of water with high pressure for the movement of stool. One flush is enough to move bowl residues into the draining pipes.

Damaged sewer lines

The poop stays or floats on the lower side of the bowl when sewer lines are obstructed or blocked with foreign particles. The hard water deposits and calcium builds on these pipes and narrow their diameter.

The narrow pipes do not allow bulky waste and water to move smoothly. In addition, the issue also comes due to cracked or broken sewer lines.

Furthermore, the problem comes from a bad and old-fashioned plumbing system that does not hold excessive waste in the lines.

These can break or crack when you add cleaning agents frequently in the drains for unclogging. The harsh cleaning agents mixed with bleach and ammonia decrease their strength.

The incorrect use of plunger devices also increases the risk of their breaking. You can use homemade solutions to remove hard water deposits.

Mix the vinegar and baking soda and pour the solution into the toilet drains. The reaction of these two components can unclog the calcium buildup and clear the sewer lines.

Blocked toilet inlet holes

The inlet holes are present on the bottom side of the toilet bowl. The primary function of inlet holes is to allow water movement when you press the tank’s handle.

These inlet holes can get blocked and do not allow sufficient movement of water and leading to poor flushing. The waste cannot move into the draining system because of insufficient water flow through these inlet holes.

Bacteria and minerals in water can clog these inlet holes. You can resolve the clogging issue by pouring the warm vinegar into the overflow tube.

Flush the toilets after 50 to 60 minutes of pouring the solution. It can wash out the calcium and bacteria colonies from their surface.

The issue with a water tank

The faulty internal components of the toilet tanks often cause difficulty in the movement of the poop. The flapper seal controls water flow and prevents dripping and leaking in the bowl.

The flapper seals can get damaged due to overuse and debris building up on their surface. Algae can also grow on its sides and make them faulty.

The damaged flapper seal does not provide enough water with pressure to move the waste from the bowl. In addition, the issue also comes due to faulty or damaged chains connected to the flapper.

The broken chains cannot lift the flapper properly for enough water movement. The water pressure also decreases because of the insufficient opening of flapper seals.

The problem also comes when the water level in the tanks is low. The pressure automatically decreases due to insufficient supply.

Open the tank’s lid and inspect its internal components. Replace the flapper seal and connected metal chains if damaged and add the new one.

Check the water level and ensure the correct functioning of the supply valve.
