Attachments/gadgets

Grip

It should work fine, its simple so as long as there are no leaks ball valves work well, if you want more power you can always buy a QEV, or spring load the valve
Good Luck

Yep should work... I would suggest spring loading the ball valve. This will probably double performance...

if you are going to use a ball valve i would get a burst disk and spring-load the ball valve.

Why bother with a ball valve when you can get a sprinkler valve for 25 quid?

"Bob" are little people, (generally of male gender...but with some European ladies...when they don't shave, who can say quantitatively??? :roll: ), loosely resembling fairies or leprechauns, which in certain parts of Europe are traded for goods and or services....much like cash is used on this side of the pond. :wink:

I hope no one asks "What's a sawbuck?" though...they really don't want to know. :lol:
