I'm in the process of installing a new shower, including new pump and pipework.
My plan is to site the pump next to the HWC, feeding hot from a dedicated essex flange and cold from a dedicated feed from the header tank in loft (about 3m directly above the pump).
I then plan to pump the water back up (about 3m) into the loft, across (about 2m) and then down (about 2m) into the bathroom.
Question: Will I need to install some kind of bleed / vent at the highest point, or not? Although the pipes will be up in the loft, they will not be any higher than the top of the header tank.
Thanks
