It’s more likely that you’ve experienced a slow flushing toilet once or multiple times.

This abnormal situation needs to be investigated and fixed, especially when running an independent system like a septic tank.

The ‘why’ and how to solve the problem are what we seek to discuss here.

You’re likely reading this article because you face the same problem. If you are, you only need to be patient and read through this short article to find answers. The good news is a slow-flushing toilet situation can be resolved.

Without an iota of doubt, toilets play a crucial role in homes.

Your toilet is one of the most essential parts of your home’s plumbing system. Many homeowners may be oblivious to this fact until such toilets malfunction.

Two Possible Causes For A Slow Draining Toilet

There could be two possible causes whenever your toilet flushes slowly. A malfunctioning fixture may be the first probable cause. The other may be due to issues with your septic tank.

The smooth functioning of your toilet is closely tied to your septic tank condition. This is why we’re considering the relationship between the two. Slow-draining toilets due to faulty fixtures are minor and can be fixed easily.

However, septic tank-related problems are significant and must be urgently investigated. Your slow-flushing toilet is a symptom that points to a developing problem.

The likelihood of a filled septic tank is among the many possible causes of this problem.

There’s only one significant action to take when dealing with a filled septic tank. It involves pumping the tank. This should resolve the problem of slow flushing.

Pumping Your Septic Tank

When a septic tank reaches capacity, one of the first signs it shows is a slow-flushing toilet. When this is noticed, you first need to find out when you last pumped your septic tank.

Septic tanks must be pumped once every three to 5 years, depending on the size and number of users.

Sometimes, you cannot know whether the tank is complete unless you investigate. We recommend that you leave such a task to the experts. Opening a septic tank is a high-risk situation due to releasing dangerous gases.

Apart from the foul odor, excessive exposure could knock you out. In severe cases of exposure, death may result.

So, it’s best to call a licensed septic technician or service to take a look. Their findings answer whether to pump your tank or look elsewhere for your slow-draining toilet problem.

Experiencing Slow Toilet Flushing Even When the Septic Tank Was Pumped Recently?

As stated earlier, a recently pumped septic tank does not guarantee you won’t experience a slow flushing toilet.

In this situation, you’ll need to look elsewhere. You’ll need all the help you can get in spotting the issue and finding a lasting solution.

A licensed plumber will significantly help your quest to solve the problem. There are several possible reasons why you’re having a slow-flushing toilet.

These include mild clogs, water tank settings, improper ventilation, waterline sediment, flapper valve issues, and hard water.

  • Mild Clogs

One of the possible reasons why you’re experiencing a slow-flushing toilet could be due to mild clogs.

Mild clogs allow for the partial or sluggish passage of water. Objects may be accidentally dropped down the toilet, thus preventing the free flow of water.

A plumber will need to be called immediately to get rid of such clogs. Possible tools to be used include plumbing snakes and plungers, among others.

  • Water Tank Settings

The water tank position is always above the toilet seat.

This water reservoir setting could be tampered with. When this happens, less water gets supplied to the bowl when flushed. You’ll have to make the proper adjustments to allow for increased water flow and flushing efficiency.

Consider raising the float arm to increase the water volume in the tank. More water volume is likely to increase toilet flushing efficiency.

  • Improper Ventilation

Poor ventilation is a possibility as to why you’re experiencing a slow flushing toilet. It has to do with inadequate pressure. Gurgling sounds are among the primary symptoms you’re likely to notice.

When this is noticed, it’s simply a pointer to the possible absence of air in your plumbing waste line.

This can be resolved with the help of an expert. When an expert arrives, he proves for all sorts of issues. Improper ventilation is determined after conducting several assessments, all showing apparent symptoms.

  • Sediment in the Water Line

Concerning sedimentation in the waterline, it goes beyond the toilet.

This is also noticed in other water outlets. The leading cause for this is a buildup of sediments, which eventually gets in the way of free water movement. Less water is allowed into your plumbing fixtures, contributing to slow flushing.

You’ll need to call a licensed plumber to check the exact problem. Sediment accumulation in the water line isn’t a complex issue at all and can be resolved within a short period.

  • Issues with Flapper Valve

Your toilet’s flapper valve can also cause slow flushing. You may wonder which part of the toilet your flapper valve is in. This component is the rubber stopper at the bottom of the toilet bowl.

As time goes on, the optimal performance of the flapper valve decreases. It is only a matter of time before this reduction in flapper valve performance affects flow.

When it is determined that the flapper valve is failing, a replacement will be necessary.

  • Hard Water

Challenging water issues extend to toilets, too.

Hard water contains many minerals, including calcium and magnesium carbonates. As you continually use such water, there’s a steady and slow deposit of hard water minerals in pipes and the toilet.

Removal of these minerals is necessary for optimal functionality.

The relationship between slow toilet flushing and septic tanks has been highlighted. We’ve also seen that sometimes, septic tanks might not be filled, yet slow flushing may be observed.

For such development, we’ve provided possible reasons why this could be so.
