Inline pipe valve/taps dripping after turning off and back on

[Gary555]

I’ve recently moved into an old house and I’ve just replaced the immersion heater in a copper cylinder.
The problem is that, to stop the tank from refilling I turned off two pipe valves (not knowing which did what) and now I’ve truned them back on they’re both dripping. How do I stop the dripping? Do I replace the valve or can I tighten the slim nut beneath the tap heads?

You can tighten the gland nut "slim nut)

As above, some valves have a gland nut that can be tightened or repacked, other than that replace the valves - full bore lever valves cost more but are more reliable.

Ok, how do you repack if I was to have a go?

If I was to replace them which seems the best solution, I’m just not sure which pipes are for what, so I guess I’d have to drain the system and hope for the best when I undo the compression fitting ha ha

Loads of info online about repacking gland nuts, quicker than one of us typing it out for you 😀

Aah right repacking sounds simpler than I thought, I’ll get myself some ptfe tape and give it a go. Thank you.

Success - valves repacked and not dripping and new immersion up and running.

Admin can close this thread now if they like. 🙂

Thank you.
