What size plumbing for 22 gallon setup?

[izg]

Hi there,

I've got a big shiny pot (100litres) and a mash tun all insulated with foil and bubble wrap (75litres), and I'm about to go and buy the tank connectors (I believe you call them bulkhead fittings in the US) and ball valves.

But I've just realised, will 1/2 inch be big enough, or should I get 3/4 fittings? The mash tun already has a 26mm hole in it, so will need to be reduced to 1/2 inch anyway if I go for this option.

Thanks for any advice!

My brewpot is around 22 gallons too. I set my system up for 1/2". It seemed the logical choice since the pumps I use are the same size.
