Fellas,
I'm getting my pump delivered tomorrow (one of the morebeer March ones -- got stung for VAT big style

). Now I plan to have the brewery on two tiers. Is there any problems having the HLT on the upper tier, fly sparging via gravity, then pumping from the MT to the Copper while carefully controlling the speed of the pump? Or is it preferable to have the MT on the upper tier and pump upwards and drain the liquor via gravity into the kettle?
Also how far below the tap does the pump need to be for it to prime?
Cheers!
