Power flushed a one today, 20 rads, some are great, like the back of the house where its been re-piped, others on the old system not so great, warm, you can keep your hand on them, theirs 2 on the old system like that and the last one, the furthest one away is new, piped up in 8mm and again Lukewarm.
I never work on big systems like this, but am i right in thinking i can add another 15/60 ? on the return next to the old pump or 1 25/80 ? or should i skip all that and re-pipe the 3 rads that are just pants ? current pipework in 22mm core, its messy and 15 off shoots, one on 8mm, its a 15/60 pump..
Cheers for the help.
