How to fix a gurgling toilet

1. Clogs

A common culprit of toilet gurgles at end of every flush includes debris, sediments, plastic or non-flushable materials that pile up and block the drain, preventing air from escaping either from the vent stack or sewer line.

 These obstructions always cause air to escape backward – making the dreaded gurgling sounds.  

toilet gurgling when flushingThe best way to clear minimal blockages in the toilet bowl is by using a toilet plunger.

This tool successfully removes any blocks caused by tissue, hair, or poop in the toilet drain, which is preventing air from escaping the vent stack or sewer line whenever one flushes the toilet.

For an extreme remote blockage either in the toilet bowl or the toilet drain, this requires snaking. A toilet auger is the best tool for this job, the device works by rotating the handle clockwise while creating a screwing action that penetrates through the clogs disintegrating it completely.

2. Air in the Lines

The leading cause of a toilet that burps big bubbles when flushed producing a myriad of awkward sounds, is air that fills up in the toilet drain and down the sewer line resulting in a constant gurgling and bubbling in the toilet.

To successfully remove all this build-up of air, first use a toilet plunger to pump out excess air in the toilet drain and remove any clogs down the toilet bowl and drain, this will reduce the spurt (air gush out in a sudden) and if the problems persist, check for a plumbing leak that leads to your toilet drain from your sewer line (plumber services will be needed).


3. Sediment Buildup

The main cause of gurgling noises when flushing the toilet is the buildup of calcium, magnesium and iron. A high concentration of these minerals over time results in the formation of a red-orange fur inside the toilet tank and water inlet pipes, a residue left behind by Hard water.

The buildup of sediments clogs tank equipment especially at the entry and exit points causing water to gurgle and spurt while flushing the toilet.

The buildup of these minerals appears inside toilet tanks and water lines forming a red-orange fur which tends to prevent the smooth flow of water every time one flushes the toilet.

To avert the gurgling noise when flushing the toilet, it’s advisable to clean out any noticeable iron and bacterial buildup inside the toilet tank. One can use a toilet brush and a bleaching agent to remove all the red-orange fur.


4. Vent Stack Blockage

A toilet vent stack helps remove odor and gas between the sewer line and toilet. It is mostly used to regulate air pressure inside the toilet drain pipes.

If your vent stack is blocked with stacks of leaves, birds nest, branches and dust buildup, this will affect air circulation within the toilet drain and the vent stuck.

So, whenever one flushes the toilet, the clogs will hinder air circulation inside the plumbing system affecting the rate at which the toilet drains, causing the gurgling sound inside the toilet bowl and tank.

A possible solution: one needs to examine the vent stuck from the top if there are stacks of leaves and branches clogs, which can be easily removed by a hook and wire.


5. Tank Equipment – bubbling toilet that won’t flush

Toilet tank gurgles are annoying and can persist. First, let’s start by looking at the source of the problem, the most probable culprit of toilet tank gurgle is when a float ball and fill system are faulty and struggling at the same time in most cases when one flushes the toilet.

One should make sure the float ball works correctly every time the water fills the tank and when the toilet is flushed.

The ball lock assembly should not have iron-orange fur buildup which generally prevents the float ball from working correctly. Having said that, the water level should always be 20 cm below the overflow tube.

Finally, check for any corroded or malfunctioning components in the tank, try and remove all the corrosive buildup with a brush and a bleaching agent. If the problem persists, contact a professional to check the problem.

Conclusion
A gurgling toilet is not in any way an indication that you need a replacement. It is a common problem that arises from time to time brought about when your vent is stuck and clogged. The five steps provided above will assist with this problem when keenly followed. You will be able to have a problem-free toilet without the need of a plumber to fix the problem.

FAQ

What does a gurgling toilet mean?

Toilet gurgle is the awkward sound produced either from the toilet bowl or tank as a result of air escaping backward due to blockages or malfunctioning components. For blockages, this might be from the sewer line, vent stack or toilet bowl.

The forceful negative air pressure pushes itself back into the toilet bowl making the water to bubble producing a bubbling sound.

Simple tips to fix a slow draining toilet?

Experiencing a toilet that is taking ages to drain once you flush? Here are simple do-it-yourself steps that can aid you fix any issues without calling a plumber.

Common reasons for a slow draining toilet and how to fix them:

Clogs in the pipes

A toilet that is slow to drain when flushed might be as a result of an obstruction in the pipes that is preventing water from flowing in the right way. A plunger is the best tool that can dislodge any clog in the toilet bowl and drain.

Mineral deposits in the toilet tank

Most toilet tanks are made of metal and plastic which are prone to iron-orange fur or even sediment build up inside the tank.

This mineral buildup tends to affect the flapper valve, which creates a watertight seal that holds water until someone flushes the toilet.

The mineral deposits hinder the flapper from working correctly, thereby affecting the rate at which water flushes out. Having said that; replacing these parts isn’t too expensive.

Toilet flush mechanism

Over time, toilet systems tend not to work correctly at it(check??) should, especially the flapper or the chain connected to the flapper. If the chain that is connected to the flapper is tangled, broken or the flapper itself is loose, this will affect the rate at which the toilet flushes.

Check to see if the chain is tangled or broken; one can untangle the chain so that it can work correctly.

Toilet blocked & blowing bubbles

A common culprit of a bubbling toilet might be a clogged vent stack. The vent stack allows the flushed water from the toilet; the air needed to drain appropriately.  Also, vest stack acts like a breather that prevents horrible smell back in our bathrooms,

So, to avoid the toilet from blowing bubbles, first check if the vent stuck is clear from clogs like bird-nest, branches, leaves, etc. one can climb to the roof and check if the vent stuck is clear from any blockages.

If there is any, one can remove them by hand or using a hook. This will aid you to remove clogs that are a bit far. The final step is to flush the line with a garden hose to clear any remaining clogged.

Air bubbles in my toilet tank

These small tiny bubbles that seem to sit in the toilet tank are mainly caused by a water supply line.

Water that contains air regularly travels inside the toilet tank. The air which is unable to escape becomes visible as bubbles inside the floor of the toilet tank.

This is evident when the toilet tank refills after flushing the toilet, one can hear a sputtering sound as water shoots through the fill valve in to the tank.

How to stop bubbles inside the toilet tank:

Even though air bubbles aren’t something one should be worried about, the only remedy to get rid of them is by flushing the toilet multiples times throughout the day. As water flushes, those tiny air bubbles will be exposed to air allowing them to escape.

My toilet spit water when i flush

This happens when the toilet bowl isn’t receiving the required amount of water when one flushes the toilet. Maybe the flush valve refill tube is not properly fitted or the fill valve is not working properly.

So this is affecting the required amount of water reaching the toilet bowl forcing the toilet to spit.

The most probable solution is to reattach the refill tube firmly in place if it isn’t working the way it should, then replacing the fill valve.(toilet gurgles at end of flush)
