fixing a toilet that is leaking after being flushed

There is water leaking out my toilet. It seems to be dripping out shortly after being flushed. How can I find out what exactly the issue is? And what can I do to fix it? Will I need to hire a plumber or is this the sort of work that can be done DIY?

If the toilet is leaking only when flushed it could be a couple of things depending on what design toilet you have.
Most likely to be the donut washer which needs replacing or flush cone.
If the leak is further down by the toilet pan outlet the issue could be a faulty pan connector.
If your not confident in carrying out plumbing work I would recommend you leave it to a professional."

I need more specific info from you regarding the dripping toilet.
1. Is the drip running into the toilet pan?
2. Can you only hear the drip coming from inside the toilet cistern?
1. The drip is running into your toilet pan this is a two part answer.
a. The “Flushing unit needs setting to the correct level or the inlet (ball) valve needs adjusting so that the correct water level inside the cistern is obtained.
b. Once this has been corrected and the dripping into the pan continues the flusher unit needs repairing or replacing.
2. Only hear the dripping coming from inside the toilet cistern.
a. The inlet valve diaphragm needs to be replaced if this is not possible then a replacement of the inlet valve will be needed. ."

It seems to me like its the doughnut washer or flush valve. I would get a plumber to come and have a look. Most dont charge call out so you'll be able to get free one to one advice.
Hope that helps."

I would firstly recommend that you hire a Plumber. And for your information it could be the Doughnut washer which needs replacing.

Kind Regards"

"Sounds like doughnut washer that sits between toilet and cistern best to renu I would get a plumber as can be difficult to get to if you’ve never done before as cistern has to come off wall."

"there may be several problems, rather, please hire a plumber, it will be difficult to fix it yourself, you can also worsen the problem"

"I’d suggest doing some investigative work by yourself first and then call a plumber if 1. You’ve found the issue 2. You’re still clueless as to the location of the leak.

Try checking the pan flexible connector. The seal might be broken which invariably leads to a slow leak."

"It sounds like the donut that connects the cistern to the pan these can perish over time a cheap part but I would recommend a plumber"
