Help please the last few days my toilet is broken .
The water level is low and won't flush things down it causing a blockage .
I have tried a coat hanger plunger and mr muscle toilet cleaner in the toilet .
Any other ideas I camt afford a plummer

We need to clarify some issue here before we do a fix. Water level is low, is that in the bowl or in the tank? If the bowl is low it is likely low due to siphoning caused by a blocked vent. If plunging doesn't clear it you may have to take up the toilet or rod from the roof stack, which would be easier/safer for you?

For a low bowl level do this. Lift the lid and check the tank level. It should be 1/2" under the white overflow tuber. Now check the small tube that runs from the ballcock to the overflow tube, That fills the bowl as the tank fills.
Get your tank adjustments correct and I bet it will flush better. If not then click back and tell me. Good luck, Tom
