Faulty stopcock ??????

[chicklet]

HI Everyone

I think I have a faulty stop cock. I turned both hot and cold water off in my bathroom while I was tiling behind the sink.

When I turner them both back on, only the hot came on. The stop cock for the cold water is just turning freely and not letting water through.

What do I do. CAn I replace it???

Any help would be appreciated.

Thanks[b[/b]

Hi Again.

I don't know if this helps, but the valve is red and round. I hope this is the stop cock and I've not confused anyone.

Thanks

Red and round sounds more like a gate valve to me tbh. They do have a tendancy to sheer off if turned to hard and are fairly unused.

What do I do about it. I can't get my cold water back on in the bathroom??

Meaning you need to drain the cold water tank and change the valve for a full-bore lever valve:


Change this:

for this

obviously using the correct sizes....

or two adjustable spanners.

I think I could do the swapping over. But how do I drain the tank ???

Sounds really messy?

Thanks for the advice so far.

tie up the ball valve in the cold water tank to stop it refilling.

Turn on any tap that is fed from that tank, and leave it on until the tank is empty.

Or buy a pair of rubber bungs from the plumbing tools counter (but this is a bit more risky if you make a mistake)

I think I could do the swapping over. But how do I drain the tank ?

Through the cylinder and out of the bath tap. Unfortunately this will lose all your hot water, but whadd're ya gonna do?

 

[chicklet]

None of the taps coming from this tank will run??? Can't get them on because of the valve not turning.

Is there any other way to drain it. The tank is in a cupboard and I can't get in the top of it????

 

[chicklet]

Sorry for sounding dense!! Please bear with me!

Oh my word, those Pegler lever valves are just raw sex.

 

[chicklet]

So, If I get into the cold water tank and tie up the ball valve. Let the hot water bath tap run, It will eventually empty the cold water tank???????

Is that right or have I got it completely wrong?

 

[Softus]

You've got it completely right. However, it would be better to shut off the mains supply to the cistern.
