Due to the relentless usage the first causality of your toilet is usually the toilet handle. Do not be petrified, instead lift the tank lid and you’ll find a screw at the back of the handle, just tighten it and you’re good to go.
How to unclog pipes
If your toilet pipelines are clogged, never ever flush the toilet mindlessly to unclog it because the water would very soon start to overflow and well, you do not want to swim in toilet water right? The easier way out is to use hot water and dishwashing detergent powder. Mix it and fill the toilet bowl with it. Leave it like that for an hour so that the blockage is broken down. The clogged obstruction will get flushed out easily.
Find a leak
Well if you believe that your toilet is leaking from somewhere or it’s flushing water slowly by itself you can try and identify where the leak is coming from. Put food coloring or Kool-Aid powder into the flush tank and keep it for at least 15 minutes. See if the color in the toilet bowl has changed, if yes then you’ll have to call a plumber for this one as your toilet has serious leak. Which will result in water wastage?
Fill a plastic bottle with sand or small pebbles and put it in your tank to save water every time you flush. This will not weaken the flush water pressure.
