Hi, I am about to install a new bath which I have purchased with a combined overflow and filler, which will be fed by a mixer/diverter mounted on the wall above the bath, which will feed both the bath and the shower above the bath. The connector on the side of the filler/overflow is ½”BSP and I was planning to connect between the mixer tap and the filler with 22mm copper. However I have the following questions :
I had always assumed that the filler/overflow should be positioned on the same wall as the mixer, but this gives me a problem with how to connect the 22mm pipe from the mixer to the filler. There is no way to access the back of the filler once the bath is in position. If I connect to the filler 1st and then connect to the mixer I will have to cut a channel in the plasterboard and not tile between the pipe run and the mixer, until after the bath is installed, I don’t really want to follow this route as I don’t want to break the plasterboard at the lip of the bath to maintain the seal on this edge.
So I have considered using a flexible pipe connected to a 22mm copper pipe that runs down from the mixer and connected to 22mm copper that goes into the filler. This would allow the bath filler to be connected and then the bath slid into its location. However the maximum bore flexible pipe I could find was 13mm so would this restrict the flow to the bath, considering that he connection to the filler is ½”bsp anyway ? and that there is both hot and cold running down the same pipe (the hot water system is supplied by a Megaflow)
The other option I considered this morning was to turn the bath through 180 degrees and mount the filler on the outer edge off the bath (i.e. away from the wall) This would make fixing a lot easier for both the filler and the waste as they will both be on the accessible side of the bath. However will this be ok because the 22mm copper from the mixer will run under the bath and then back up to the filler so a lot longer run than before (1/2m compared with probably nearer 2m)
