Emptying a toilet cistern with no shut off valve advice

ferry

Hi all.

Couple of issues relating to our toilet I need help with please.
Our downstairs toilet makes a horrible groan after each flush and doing some research it seems I might need to change all or part of its internals.Oddly enough the noise goes away when we turn on the sink tap next to it?
It has the standard ballcock internals but has no water fill shut off valve so looking for ideas on how to get around this to enable me to work on its internals
Thanks for any advice

i would say , if you carnt work that out !, you need to get a plumber to do the job for you, im not trying to be rude to you, i think you may be takeing on more than you can chew.

The 'groan' will be the shut off washer in the ballvalve vibrating back and forth. When you turn the tap on on the sink the pressure on the ballvalve washer reduces as your incoming water pressure takes the path of least resistance i.e. out of the tap you have just opened.

And yes, internal stop c o c k or if thats knackered then the external stop c o c k is the only way to shut off the supply to the toilet if you have no in line valve.

There should be/might be a shut-off valve at exit of the cold water tank, assuming it is tank fed and not mains fed.

Tie up the ballcock to prevent it refilling. Obviously that will not prevent water inflow if you remove the valve though.

As it would appear that the problem is with the filling mechanism. You will have to isolate the cistern in order to do any work on it..You will need to turn the stopcock off, wherever it is situated. Once that is done you can empty the cistern by flushing the toilet and getting the rest of the water out with a large sponge.
Then fit an isolation valve in the feed to the cistern. They only cost a pound or so.

It is the ball-!!!! that regulates the water. As has been said shut the water down, at the stop-!!!!, drain as much water as practical (via a flush), disassemble the ball-valve, and replace the washer - if the ball arm is an old metal one - might be a good idea to replace that to - less wear on the washer.
Reassemble, and put the water back on - though slowly, too fast and you'll drown the float and have an overflow!
