These are the most common problems that cause a slow flushing toilet: Defective flush valve or flapper. Clogged drain vent. Mineral buildup.
The most common causes for a slow-draining toilet are: A clog in the drain line. A blockage between the tank and bowl. Poor or Clogged Venting.
For preventive drain cleaning, you can use Drano® Max Build-Up Remover in drains, toilets and even septic systems. Apply Drano® Max Build-Up Remover overnight or before you go to work, then wait 6 to 8 hours before running warm (not hot) water down treated drains or flushing treated toilets.
If you want a more efficient and powerful flush, look for a new toilet with a tower flush valve instead of a flapper. Tower flush valves allow water to exit the tank from 360 degrees, resulting in a faster and more powerful flush.
TOTO Ultramax II ( Strongest flush) : This toilet features TOTO's proprietary Double Cyclone flushing system that uses two powerful nozzles to create a centrifugal, cyclonic rinsing action, resulting in a strong and efficient flush.
Over time, flappers wear out, which allows water to continually drain from the tank. The result is not enough pressure released at flush to completely empty the contents of your toilet bowl. You can fix this problem by replacing the flapper. It is easy to do with any standard flapper purchased from a hardware store.
If you're dealing with a toilet that won't flush, check to see if something is damaged or broken within the toilet cisterns like you would the fill valve if your toilet is running. Check your lift chain, flush valve, water valve, float ball, and more. If you cannot see anything, you may call a plumber.
If you don't believe that, turn the valve off on the water line line coming into the commode and flush it and you will see that it will work just as well without any water pressure. Yes, it will take longer for the tank to fill with low pressure, maybe two or three minutes instead of 30 seconds.
Use your instincts; if it looks like one cup is going to cause too much fizz, use less or pour more slowly. Allow the fizz to sit for at least 20 minutes. See if it worked. Once the clog is broken up, the water level should go down.
High level cisterns can be said to benefit from improved gravity and greater pressure with the higher cistern helping water flush with more force.
Common causes of a slow-flushing toilet include low water levels, a partially clogged drain, mineral build-up on the jet holes, a defective flapper, and a blocked drain vent.
Simply pour about half a cup of dish soap into your toilet bowl, followed by one cup of vinegar, then let it sit for about 30 minutes before flushing. Using dish soap and vinegar to unclog your toilet is not only cost-effective but also eco-friendly.
Combined, baking soda and vinegar can sometimes clear a clogged sink, but in many cases, they can also take care of a toilet clog. However, to avoid a small eruption all over the bathroom floor, you'll want to measure them very carefully.
It is Extremely Corrosive For Your Drains
This can put a great deal of stress on your drains as the heat can cause PVC pipes to soften and even break or collapse. While it is dissolving your clog, Drano can also quickly eat away at the glue holding your pipes together, leading to a potentially costly leak.
Vinegar will not damage your toilet in any way if it's left in your toilet overnight. In some cases, leaving the vinegar in your toilet overnight is recommended to get the best cleaning results. No matter what material your toilet is made from, the vinegar will not damage your toilet.
Tips to Keep Your Toilet Clean Longer
The aforementioned baking soda and vinegar is a safer alternative for keeping your toilet bowl sparkling. You can add them to the toilet bowl at the end of the night for a good, cleansing soak until morning.
Pour Hot Water into the Toilet
When you see the symptoms of a nasty clog, the best option you have is to pour hot water into your toilet bowl. You can use the hottest setting from your faucet first. If you need to heat some in the microwave or the stovetop, you don't want it to reach boiling temperatures.
Stop Flushing!
The clog will prevent the water from going down the drain, meaning it will overflow the toilet and get all over the floor. This can create a much bigger (and must smellier) mess. You should never flush a clogged toilet more than once.
