Hi all.
I'm after some advice about fitting a twin impeller shower pump.
The pump is installed in an upstairs airing cupboard level with the top of the hot tank & will be connected to the tank via a surrey flange. I've put in an anti gravity loop to drop the supply from the flange down about 250mm which the pump manufacturers recommend.
The hot & cold pipe work from the pump to the shower mixer has to go up into the loft, along the loft floor about 1metre then down into the bathroom.
What i want to know is do I need to fit auto air release valves in the pipework in the loft where the pipes run along the floor. I was told it is a good idea to fit them but would like other opinions.
Also at some point I have to change from 22mm pipe (from the pump) to 15mm to connect to the mixer. Does it make any difference where I reduce down, the best place for me is in the loft at the end of the 1metre horizontal run.
Thanks.
