Why is my toilet making a hissing sound at night?

Not sure what is causing this. Anyone know!

Cistern valve needs replacing or adjusting.Easy DIY in most cases, or call a plumber.

Some one has left a one eyed snake in there!

Sounds like the washer on the inlet needs replacing. not hard to do

If you can't get a new inlet washer for less than a dollar, I make washers out of butynol that seem to last for ever.

I'm guessing it's possessed!

Well either that or what the others above have said.

Or it could be like mine, and have a bumble bee nest in the wall behind the cistern!

Thanks for everyone's help. Yep, I thought it might be a snake and then I realized the only real live snakes we have in NZ are our politicians.

LOL you funny too. Nice one.

could be either inlet or outlet leaking. if you can see a trickle of water running into the pan while it is filling up then it is the outlet washer. best bet is to replace both washers. Bevan
