Fair enough, - that's okay & would work fine if the pipes had good flow. Looks like you have to get those pipes joined to the bigger pipes somewhere.
Will be a fairly easy job getting these pipes to the main 22's in the boiler cupboard as its only about 2m away and the joists run parallel. just out of curiosity, would a 6m head pump as opposed to a 5m head pump make any differance?
