Hey guys just been looking at UKPSF and its a little contradicting on ally bottle hydro tests.

In the first part it says 5 years but under that in bold writing it says 10 years, I'm just wondering which is correct as my friend wants to use my old ally bottle that i dont use anymore.

Hope one of you nice people can help me out.

Thanks

Aaron A

p.s

hope this is ok in this section of the forum.
