Addressing Weak Toilet Flush

Why do I have to flush my toilet twice?

Do you have a toilet in your home that always appears to need two flushes? This is not only inconvenient, but it is also wasteful of water. But, before we get into why this is happening, let’s go over how a toilet works. The majority of toilets have rather simple mechanisms. Water is kept in the bowl and tank. Depending on how these systems are working together will influence its overall strength.

When you pull the handle, water flows from the tank into the bowl, causing a siphon effect that draws everything in the bowl down the drain and into the sewer. This should empty your ‘business.’ The toilet bowl and tank will then be refilled in preparation for the next use. So, what happens when you need to flush twice? Typically, this is due to insufficient water flowing into the toilet bowl to effectively flush the toilet. If you want a professional to take care of everything, we offer affordable toilet repairs.

You have a poor quality low-flush toilet

Some low-flush toilets simply do not generate enough suction to do their job correctly. In certain circumstances, you may need to flush twice or hold down the lever to generate the necessary suction. If this is the case, consider replacing your toilet.

You have an old and worn-out flapper

As a result of frequent submersion in water, the flapper in your toilet tank (the element that keeps water in your tank) can curl or lose its sealing capacity over time. The flapper is the weakest link in your toilet. Water might slowly leak into your bowl through a damaged flapper, reducing the amount of water in your tank. It may take some time for the tank to replenish if you have low water pressure. A bad flush will occur if there is insufficient water in the tank. This is most likely the case if your toilet flushes normally at times but requires two flushes at others.

You have hard water buildup in your bowl

Minerals from hard water can accumulate in the openings that allow water from the tank to enter the toilet bowl. When too many of the holes become clogged, your toilet bowl receives inadequate water when you flush.

You have a partial clog in your drains

Pour a pail of water directly into your toilet bowl (not the tank). Your toilet should flush as a result of this. If the toilet still does not flush properly, there is most likely a clog in the bowl or the drain plumbing that must be cleaned. We can assist you with this. Alternatively, if necessary, we can place a camera inside your pipework to check if there are any problems.

Your flapper closes too soon

If you hold the handle down, does your toilet flush on the first try? If this is the case, your flapper may be closing too quickly and not allowing enough water into the bowl. To see if it helps, try shortening the chain. Alternatively, ask us about a specific flapper that will address this problem.

What causes a weak flushing toilet?

You know how frustrating it can be to spend time in the middle of your number two session attempting to fix a toilet that won’t flush. You may have wondered, “What causes a weak flushing toilet?” whether you’re cleaning out your tank or checking for a leak. Toilet leaks are one of the most prevalent plumbing issues, and they can be a big pain. In this section, we expand on what we discussed previously and explain what causes a weak flushing toilet and why it occurs.

Toilet clogs

Let’s begin with the most obvious cause of a poor flush: a clog. The trap, which is the curved channel in the toilet base that stores a small quantity of water to prevent sewer gases from rising from the drain, is where the bulk of toilet clogs occur. Because of its form, the trap can also become clogged with toilet paper and other items, resulting in a partial or entire clog. Using a plunger will typically dislodge and push the obstruction through the trap, restoring normal flushing power to the toilet.

Worn-out flapper

The flapper is the spherical, rubber element of the toilet tank that produces a watertight seal. When you push down on the toilet handle, the flapper raises, allowing water to move from the tank to the bowl for a limited period of time, resulting in a flush. The flapper can wear out or become out of place over time, causing it to no longer maintain a tight seal. When this happens, water slowly leaks from the tank into the bowl, resulting in less flushing power when you want to flush. Fortunately, most toilet flappers are simple and inexpensive to replace.

Issues with the handle and chain

While inspecting the flapper, check the toilet handle and chain to confirm that the entire mechanism is operational. The toilet handle may become loose and need to be tightened. The chain that links the handle to the flapper can get unclipped or set at the wrong length. Adjust the chain so that when you press the handle, the chain pulls up the flapper to start the flush and then drops down to close off the hold at the end of the flush.

Faulty float

Water will replenish the toilet tank after a flush until it reaches the fill line. The float, which looks like a plastic ball, rises with the water level and signals the refill valve to shut off when it reaches a particular point. The tank will not refill with enough water to make a full flush if the float is damaged, clogged, or set too low. If the float appears to be damaged, adjust it or replace it.

Clogged rim jet

Water enters the bowl through the rim jets as you flush the toilet. The little holes surrounding the toilet seat’s rim create a concentrated, swirling flow. If the rim jets become clogged by mineral deposits, bacteria, or other debris, the water flow will be disrupted and your flush will be less effective. This problem is usually resolved by thoroughly washing the bottom of the rim with vinegar and a toothbrush.

How do you fix a weak toilet flush?

A toilet with a weak flush can be inconvenient, unsanitary, and the beginning of a larger plumbing problem. The good news is that you can restore or improve flushing power with a few simple measures. Also, check out our Toilet Leaking Emergency guide.

A clear clog in the trap

As with most toilet problems, the most sensible place to start is by checking for a blockage or clog. Even a minor or partial clog can cause enough disruption in the water flow to preclude a full flush. When you flush the toilet, the water and contents must travel through a trap, which is a curved tunnel at the toilet’s base. The trap is intended to keep sewer gases from backing up, but it is also the site of the majority of toilet jams. To clear any clog, use a plunger or plumber’s snake to force the contents through the trap and down the drainpipe. Once the trap has been cleared, retest the flush to determine whether it has improved.

Open the water valve

The water valve, which is placed where the water supply line meets the bottom of the toilet tank, controls the flow of water into the toilet. The valve comes in handy when you need to cut off the water for maintenance or to prevent an overflow. However, if the valve isn’t fully opened during typical use, it may limit the amount of water that gets to the toilet. Turn the valve counterclockwise to open it and clockwise to close it.

Adjust the float

The refill tube begins to replenish the tank with water after you flush. It uses a float that rises together with the water. When the float reaches a certain level, the refill tube turns off. The refill tube should also have a refill line marked on it. Perform a test flush and observe the float to see how far it rises. If it stops before the refill line, it means the tank isn’t filling completely, which could result in a weak flush. You should get better results once you move the float to the proper location.

Fix or replace the flapper

The flapper’s job is to produce a watertight seal at the tank’s bottom. When you flush the toilet, the flapper opens to allow water into the bowl and then closes to allow the tank to refill. A few things can happen to the flapper over time, allowing water to escape from the tank into the bowl and reducing flushing power.

Unclog the rim

If the tank components are fine, the issue could be in the little pores on the bowl rim that leak water after a flush. If these holes become clogged with mineral deposits or other debris, the water will not have enough force to flush properly. Scrub the rim of the bowl with a bristled brush and toilet cleanser, paying specific attention to the holes beneath the rim. After a thorough cleaning, perform a test flush to ensure that the water shoots out of the rim correctly.
