### ⭐⭐⭐⭐⭐ What are they like?

### ⭐⭐⭐⭐ Great value for money

Needed to replace olive for a copper one. Everything else is brilliant and great quality.

### ⭐⭐⭐⭐⭐ Just works
*by D***D on 29 January 2025*

I couldn’t get the feral off the old valve so I had to saw 15 mm of the end of the copper pipe, but it’s still the highest point in the central heating system. Fitting the venting valve was extremely easy having drained the central heating system and applied PTFE tape to the thread, went on without an issue.And the first for me it didn’t leak 🤣. Don’t forget to loosen the plastic cap slightly on the top of the valve to allow the free air to escape.
