shower pump question

[rolysatch]

hi

i'm fitting a shower pump in my airing cupboard and i'm just figuring out the routing of the pipes from the pump to the bathroom. will i have any issues if i take the pumped hot and cold back up into the loft and then back down into the bathroom (which will be a lot easier than going under the floor)?

Possible issues - air in the pipes which will be difficult to get out, the hot water will take longer to reach the taps, increasing wastage.

thanks for the reply, well it isn't very much further so waste isn't something i'm worried about. as far as air in the pipes would an air vent prevent this? and what sort of air vent should i be looking for?

would these be the sort of air vent i would need or some sort of automatic vent? http://www.toolstation.com/shop/Hea...r+Vent+Caps+Capillary+15mm/d230/sd2708/p45763
