A quick question as I am om my way to a friends house to do a job, we are putting in a thermostatic mixer shower, as he has yet to buy the shower & I want to a run the plumbing in chased into the wall, my question is is it always hot into the right and cold into the left on thermostatic mixer valves on showers? I ask because I want to avoid having to cross over later?
Many thanks
