Replace Broken Fill Valve
If you have a broken fill valve, youll need to replace it. First you need to turn off your water supply to the toilet. Flush the toilet until all of the water is out of the tank. Next, unscrew the water hose from the bottom of the fill valve. Remove the valve and insert the new one. After you secure this into place, reattach the refill tube and the water supply hose.
Make Sure There Is No Drain Buildup:
Another common reason for slow flushing toilets is a drain buildup. To figure out if the drain is clogged try swiftly pouring about a gallon of water into the toilet bowl. If the water level that is in the bowl rises very quickly, then there is a clog somewhere in the pipe line. To fix this problem try using the handy dandy plunger! If using the plunger is not helpful you may need to snake the line.
Blocked Sewer Line Vent
Your sewer can become clogged from tree branches, dead animals, and large clogs from your toilet that built up over time. Clogs in your sewer will lead to a slow draining toilet. Cleaning this out will most likely require a plumber to fix it. They can do this with either an auger, a hydro jet, or replacing the line. You will only need to replace the line if it has physical damage.

How To Unclog Toilet Siphon Jet And Rim Holes
For this task you will need the following:
After gathering together all the necessary items, it is time to get down to business.
- Start by locating the siphon at the bottom of the bowl.
- Wear the gloves and try to feed the thin hose through it in an attempt to unclog it. If you do not have the hose, push your finger inside it and try to remove as much calcium as possible.
- Flush the toilet and check if the flushing power has increased. If it has, you have found the source of your problem. What you need to do next is to remove all the calcium deposits.
- Use a plunger to force as much water as possible out of the bowl. Alternatively, soak it up using a cloth until the bowl is completely empty.
- Remove the toilet tank lid and place it away. Make sure you place it in safe place where it cant fall and break.
- Carefully pour the vinegar down the overflow tube . The overflow tube is the large tube inside the toilet tank.
- Since the vinegar will find its way to the bottom of the bowl, you can also pour a cup of baking soda to quicken the breaking down of the limescale.
The vinegar will soak up the calcium in the siphon jet and rim holes thereby fully opening them. Some people opt to use muriatic acid but it is not good for the toilet finish, the environment and people on septic systems.

How To Unclog A Lavatory Sink
Plungers are excellent at unclogging sinks, but its important to use the right technique. All code-compliant lavatory sinks have overflows an inch or so from the rim, and plunging often results with pressure coming back through the overflow instead of pushing the clog. Cover this hole with a rag and hand pressure while plunging to take advantage of the hydraulic pressure.
When the plunger wont do the trick, it might be necessary to use a wire drain snake. To use a drain snake, remove the pop-up assembly in the sink and gently feed the wire into the drain while cranking the handle. Once the snake makes a bit of progress, advance a bit more wire from the snake and continue. This will break the clog up and push it through the pipe.
For bathrooms with dual sinks, the sink drains often meet together at a T or Y fitting. In sinks with T fittings, a snake fed through one sink drain can run across the pipes and into the other sink, rather than running down the drain toward the clog. In those cases, it might be necessary to cut out the T, snake the drain, and then replace the fitting with a Y-type fitting.
Install A Water Softening System
A water softening system removes minerals from hard water as it enters your main water supply line. This system comes in a wide range of styles and sizes to accommodate the size of your home. It can be installed in the utility closet, garage, basement, or wherever water enters the house.
Please note that a water softening system must be installed by a licensed plumber. It will cost you about $2,000 for the system plus installation.

Kitchen Sink Wont Drain Not Clogged
A common mistake that homeowners make is dumping grease, oil, and fats down the drain.
It may seem harmless, but this actually damages your plumbing.
Grease, oil, and fats turn into a sludge that sticks to the pipes walls.
As it mixes with water, especially if the water has minerals in it, the sludge thickens.
Eventually, the water cant pass through the drain.
There are a few ways you can keep sludge from forming in your pipes.
The easiest is to pour grease, oil, and fats in the trash rather than down the drain.
Another is to use a sink stopper.
Some stoppers come with a cage on the bottom that traps hair and other solids.
It can also be useful for limiting how much sludge enters the pipe.
Examining the stopper can also tell you if sludge exists in the pipe.
The stopper will have sludge on it, too.
There are also pipe-safe biodegradable cleaners that can eat away at the sludge over time.
Once the buildup is gone, the kitchen sink will drain again.

Poor Or Clogged Venting
If youve ever been on your roof, youve noticed a small, open pipe up there. Thats the vent stack for your sewage. It allows air to move through your plumbing so that water can flow downwards. Without that change, it would just sit where it is.
The vent also releases gases and smells from your house. Otherwise, stenches and noxious gasses will build up inside and make you sick.
But, outside elements can clog this pipe. A bird may nest in there, or an animal might get stuck. These problems restrict airflow.
Inspecting that pipe usually isnt feasible. But, you can look for other signs that point to this being the cause.
Are you also noticing a smell building up in the house? Is more than one toilet draining slowly? If so, the vent could be the cause.
Your Toilet Is Clogged

In many cases, the problem isn’t the toilet itself. Instead, the issue is a clog inside the toilet. Toilets are only designed to handle certain types and amounts of waste. It can be pretty easy for them to get clogged with items like sanitary products, a toy your kid dropped in the bowl, or just a large amount of toilet paper.
If you have a toilet clog, you obviously know. If there’s a something in the bowl that just won’t go down, you probably have a clog. Small clogs fairly close to the surface can be dealt with yourself. You might just be able to plunge it or poke it with a toilet brush to get things moving again. For more stubborn clogs, you or your plumber may need to use a toilet auger to get in there and unclog the toilet.

The Last Cause No Clogged Overflowing Toilet Is The Toilet Tank Malfunction
The toilet tank is a very sensitive part of any toilet. The tank always controls the flushing mechanism.
The toilet tank has many small and large parts that help hold all the water, like the Flapper, Gasket, Ballcock.
The Flapper- If the flapper gets too old, mineral deposition may cause the flapper to either not close or wear out.
In fact, a wrong size flapper also may cause running water.
Now, you may question how do you know the flapper has the issue? Right.
To check the water quality. Water from the malfunctioning tank is always clear and has no smell. Besides that, you may hear a Hiss sound come from the pot.
While you flush the water, drain properly, but water is running continuously from the leakage flapper.
The Gasket Gasket is present between the tank and bowl beneath the flapper seal. The gasket is a rubber seal that prevents water leakage while flushing.
If your toilet is overflowing while flush and the water leak from between the toilet tank and bowl- then the Gasket seal has the problem.
To solve the issue change the gasket seal.
How To Change The Gasket Seal
To change the Gasket Seal, take one towel, bucket, etc.
Replace The Damaged Fill Valve
A damaged fill valve can cause both a slow draining toilet and water wastage. Toilets that run after you flush them can make water utility bills soar. If your fill valve is the problem, then you first need to turn off your toilets water supply.
Take the tank lid off and flush the toilet so all the water drains out. Use a towel to mop up any remaining liquid. Next, unscrew the nut that connects the water hose to the bottom of the fill valve.
Pull the valve up from its base and insert the new fill valve into the hole left by the damaged model.
Use a wrench to secure the valve with a nut under the tank. Then, reattach the refill tube and the water supply hose. After this step, you can turn your water supply back on and test your toilets flushing capabilities.

Why Toilet Wont Flush Strongly
There are times when your toilet flushes but water drains slowly or fails to drain everything in the bowl. Various issues may cause this. Some of them include:
- Dirt and mineral deposits might be blocking water flowing under the rim of your bowl. Partial blockage often results in a slow and weak flush.
- The flapper might also fail to open completely. When it fails to open, little water is released thus creating a weak flush.
- You might have clogged or blocked plumbing vents.
- Old and low flow toilets always have poor flushing power. The low-pressure results in poor flushing.
- You might be experiencing a sewer line problem. There might be plants, tree roots or any other dirt that develop inside the sewer line thus creating a backup. There might also be a partial clog in the sewer line that has never been removed when plunging. This causes poor flush.
How To Remedy An Unclogged Toilet With A Weak Flush
Based on the possible causes that we highlighted in the section above, lets take a look into some of the best remedies that can get your toilet flushing back to normal.
These are just some simple home fixes that you can do by yourself with the use of regular household items, so you dont have to worry about complexity.
1. Make sure that the water valve is all the way open
You can find the toilets water valve near the wall or the floor behind it. In a counterclockwise motion, turn the valve until it reaches a full stop for best performance.
If the water fills up too quickly inside the tank after a flush, turn the valve in the opposite direction until youve reached the optimum fill performance.
2. Clean out the rim feed and jet holes
Since hard water goes through the holes constantly with each flush, there may be a buildup of hard mineral crystals that accumulate over the years.
If your rim feed and jet holes are the problem, then you can easily clean the mineral buildup out using this technique:
What Youll Need:
- Screwdriver or wire coat hanger
Procedure:
3. Adjust the water level
Here are some possible fixes that you can do if this is the case:

Unclog The Toilet With A Plunger
Sometimes the reason for a slow flushing toilet is as simple as a clogged drain. Clogs can happen for a variety of reasons, but the most common answer is that someone flushed something they shouldnt have.
If you find that the water level remains high for a minute or two after you flush, then there is likely something blocking the flow of water.
There are many different ways you can deal with this problem but we recommend one of two methods. The first method is with a plunger.
If you have a plunger, then insert it into the toilet. Make sure you wear gloves and have a good initial seal things may get messy. Give the first plunge a gentle push.
Remember that the plunger is full of air, so a hard first plunge with send water spilling backward all over you. Once you finish the initial plunge, you can begin pushing in and out faster with the plunger.
Make sure you maintain the seal. Remember that plunging is a gradual process. A deep clog may take between fifteen and twenty minutes of steady plunging to loosen.
Stick with it and be patient. If it still seems hopeless, then try our second method of unclogging.
Problems With Your Flapper
Your flapper is that small rubber seal that covers the hole in your toilet tank.
When you flush the toilet, youre actually lifting a chain thats attached to the flapper. When that chain lifts, it lifts up the flapper which allows all the water in the tank to pour quickly into the toilet bowl.
When the toilet isnt in flush mode the flappers job is to seal off that hole completely so that water doesnt escape the tank.
But if the flapper is old or damaged or that chain isnt set to an appropriate length, water will slowly leak out of the tank. And this decreases the amount of water available when you need to flush.

Mix Your Own Declogger
Avoid using harsh chemicals in your toilet by creating a DIY declogger combination of ¼ cup Epsom salt, two cups of baking soda, and about 10 tablespoons of dish soap. Add the dish soap one tablespoon at a time.
Pour the mixture into separate muffin liners and let them harden and dry overnight. The next day, drop one into your toilet bowl and add four cups of water. Finally, let the combination sit for a couple of hours and check the results.
