I live in a rented property and yesterday I tried to stop

Resolved Question:

I live in a rented property and yesterday I tried to stop the water to the toilet in order to drain the toilet bowl to clean some limescale. I tried to turn a screw as it looked like a valve but it didn't turn very much and I heard what may have been a small crack sound. Now it's leaking and I turned it back and it's very slowly leaking water (not enough to panic). I have taken two photos which perfectly show the valve and the leak, if I can send them over. What has happened? I am fairly practical and want to know what I should do. If I tell the landlord I still might have to pay for this since it's my fault.

Hi, my name is James.

I cant see from the photos where the water is leaking from, however these type of issues are rather common.

Firstly you are correct this is a isolation valve which will shut off the water to the toilet, this type of valve only turns 90 degrees to close.

From what you have said you may have either over turned \ forced the valve beyond its limit and damaged the valve which means the water is likely leaking from the screw, if this is the case you need to replace the valve (this isnt a big job, but at the same time I wouldnt think this would be a chargeable if you speak to your Landlord and tell them you notice a leaking pipe.

If the water is leaking from the top or bottom of the valve where the compression nuts are (which is more likely), you just need to give the compression nuts one tenth of a turn with a spanner, as you may have rotated / moved the pipe\valve when trying to switch off the water, just turning the nut by a few mm should do the job.

Please let me know where you think the water is comming from and if you require any further assistance.

No problem if its leaking from the screw its a sign the valve is starting to fail, you will probably find some lime scale has hardened around the minor washer you likely over compressed when trying to shut the water off.

It will probably be fine for many months, but start leaking over time or every time the toilet is used and the pressure in the pipe changes.

If you want to change it yourself (rather than notify the landlord) should it start leaking again, it would take a novice 30 minutes at most, have a look at the video here, it gives you the general idea of what is required.

To do this repair you ideally need two mole grips \ large pliers one holding the valve so it doesnt move the other unscrewing the nut, you can pick a pair up on ebay for £6. You will need a replacement valve which is about £4 from screwfix here, make sure you get the right size 15mm, I would also buy some PTFE tape which is about 50p from screwfix here. So all in all its going to cost about £10 including the tools.

The PTFE is only require if when you turn the water back on the valve starts to leak you wrap it around the compression two times and it helps with creating a water tight seal, the end of the video here probably explains it better than I am.

Please let me know if you need anything explained, appreciate if you can rate the service received so if not so I can close the case.
