Hi Tom.
I have been watching your youtube videos and found them very useful.
I have an old stop cock conncted to a mains lead pipe.
There is a very small weaping of water from the gland nut. I have tried nipping it up, but hasn't made a difference.
It's a couple of drops a day. Nothing serious.
Please could you do a video on how to repair this.
Many Thanks.

hello locknut, yes using ptfe is your only option other than changing the pipework, so here's another tip you might find usfull in that situation, Attachment Deleted |

That's great.
Thanks for the advice and videos
I've requested a "Lead replacement" pack from Yorkshire Water. I'll see what it contains. Prefer to get the work done in the summer after this miserable weather had ended

Here's some lead replacement fun. Don't worry, it won't come to this. PTFE will do it.

Ultimate Handyman is great!
Before undoing the gland nut and packing in PTFE, does the stop cock need to be turned off ? |

Clean up the spindle with some emery cloth first. Add a little bit of silicon grease. Fully turn on the stop tap before wrapping the ptfe tight around the spindle. As you turn the tap off the ptfe will now be drawn into the stop tap body, try turn the gland nut into the body at the same time. |

I have also used Orings to fix leaking glands as a temporary measure but it a no no on any valve which you wish to operate regularly.

Made me wonder what is the purpose of this design to even have a gland that can leak?

where ever there is moving water and moving parts, there is going to be leaks, stopcocks are good, gatevalves are less good and ball o fixes are shite, all qwork good from new so, stopcocks are the right choice for high pressure,  |

If out of site of course?. I'm getting too many standard iso leaking on me and I'm thinking of replacing with full lever ones, could remove handle if on display. |

to be honest I've not used many on mains pressure, I've used loads on gravity pressure and prefer them to gate valves but, on mains pressure my head says, go with what you trust, and that is stopcocks, I'd like some younger opinions on this too,
