Hi, my central heating system the gravity fed .... with hot tank in airing cupboard.
I am in middle of a DIY installation and about to replace existing bath mixer tap (with shower head) to just a bath mixer tap and then install a wall mounted thermostatic bar mixer shower, the exposed type.
We do get a decent pressure to the shower head with no complaint for the current setup.
When I removed the bath, I then realised that the pipes to the bath are actually 22mm but wall mounted thermostatic bar mixers use 15mm pipes. Since I will now connect the Wall bar mixer to the existing hot and cold using a T Joint, my fear is that a reduction in pipe width will result in a lower water pressure to the shower head. Am I right or wrong?
