To add inhibitor into towel radiator

[Knappers]

Once the towel rail valves are closed there’s no need to close any other valves around the house.

There will only be a little pressure. Just close the valves and open the top vent but with a towel. You’re not gonna flood the place, at most might be half a cup of water on the floor!

Yep - once you get to half a cup you know the valves aren't holding
