Toilet Not Flushing All The Way

🚽 Toilet Not Flushing All The Way?

One of the worst problems your bathroom can deal with is a toilet that won’t flush all the way.

When your toilet decides it wants to do this, it can leave you with a big mess, and it’s not particularly sanitary.

So when your toilet is struggling to flush all of its contents, what do you do?

Luckily we have a few plumbing experts who can help you with a few solutions when your toilet won’t flush.

So let’s get started.

🚽 Why Won’t My Toilet Flush Completely?

When you have a toilet not flushing properly, it can be a number of issues.

From a clogged toilet to poor maintenance, there’s a reason why your toilet won’t get rid of all your business. 

So one of the first things to check is the top toilet tank.

If your toilet tank is filling up all the way, then it’s probably a clogging issue or a more significant plumbing issue you will need expert plumbing help to fix.

Let’s walk through each problem and how you can fix it yourself without spending your hard-earned cash on a plumber.

🚽 You have a Clogged Toilet

A blocked toilet, in our experience, is one of the most common reasons why a toilet won’t flush completely.

Depending on where the clog is, you will likely be able to fix this yourself. But how did my toilet get clogged in the first place?

Toilets are designed for human waste and toilet paper, and that’s it!

Too much toilet paper, paper towels, cotton balls, and flushable wipes are not meant for your septic system.

If you have children, we understand this can be tough to police.

Unwanted substances can find their way into multiple locations and cause your toilet to not flush properly.

πŸ› οΈ The Fix!

Try unclogging your toilet with a plunger. When using a plunger, ensure it completely covers the drain hole in the toilet bowl.

Then, give it 10 to 15 plunges to dislodge whatever is stuck there.

Sometimes running a garden hose into your toilet can help dislodge a stubborn blockage. Then, just make sure not to flood your bathroom!

If this doesn’t work, a toilet auger can be your new best friend.

However, this can get expensive, so at this point, it’s probably best to call your local plumber.

🚽 Blocked Inlet Holes

Small inlet holes are located just under the bowl’s rim and allow water into the toilet bowl.

However, these can become blocked over time with mineral deposits, debris, and bacteria buildup.

Most homeowners don’t notice as it’s out of sight, out of mind!

A blockage here can reduce the strength of the flush, leaving you with a big problem.

πŸ› οΈ The Fix!

Get yourself a small mirror and have a look up under the rim of the toilet to check for blockages.

If you notice it’s blocked or starting to build up gunk, you can flush it out with vinegar and dislodge it with a small wire brush.

To clean it with vinegar: Heat up a few cups of white vinegar.

Then, pour it directly into the overflow tube in your toilet’s tank using a funnel.

Let it sit for about an hour in the overflow tube, and then flush the toilet.

That should help clean out the inlet holes.

The video below gives an excellent short tutorial on how to get this done.

This issue is more prevalent in areas with hard water. 

A whole-home water softening system will help in preventing mineral buildup.

🚽 Check the Toilet Flapper

The toilet flapper is what allows water flow into your toilet when you hit that flush button.

When you flush, it lifts up the rubber valve

The flapper is in constant contact with moving water, so it can twist or warp over time with continued use.

If a flapper is worn, a tell-tale sign is toilet water constantly leaking into the toilet bowl.

This means it won’t seal properly.

πŸ› οΈ The Fix!

Check it out with a flashlight and see if it’s damaged or not sealing correctly.

It’s an inexpensive part, so when in doubt, replace it.

Your local hardware store will stock it.

Don’t forget to check the length of the securing chain as well.

They are notorious for getting stuck under the toilet flapper.

🚽 The Water Level in Your Toilet Tank is Too Low.

In summary, you will need to adjust the height of the water by adjusting the float valve.

Adjust it until the water level is at its maximum and aligned with the refill line.

🚽 Poor Toilet Design or Installation

Your toilet may have been installed incorrectly, or it’s super old.

Something simple like your plumber forgetting to remove the cap off the vent pipe causing back pressure.

This simple error causes your toilet to not flush thoroughly.

There could also be a problem with the design of your drain pipes which can be equally frustrating.

πŸ› οΈ The Fix!

Realistically unless you are a plumber or a super handy DIYer, this is best left to a professional plumber to inspect.

Your local plumber should conduct an extensive inspection and troubleshoot any outstanding issues.

You may also have one of those old low-flow toilets.

This is an excellent opportunity to replace your old toilet with a new one.

You could even add one of those high-tech bidets you have been thinking of.

Newer models have the extra benefit of conserving water as well.
