I can’t see how it works……
How can you disconnect the inner pipe from the valve, open the valve to force the plastic widgit through without water pouring in?
…or is it just me??
^^ exactly what I was thinking whilst watching the show.
Youd have to remove the pipe and push it through whilst water is coming in. Which isn’t too bad as the pressure will be low, but if it fails to seal it coud be a whole load of fun
I could see it as an emergency device as it could stop you sinking but not as a maintenance device as why risk sinking your boat ?
