Researching on how to fix the issue where when you turn on the shower head you get cold water for a few seconds.
I really like the RV shower mizer. Great idea and solves the issue plus some:
But the install in my trailer will be a pretty big pain due to how its laid out.
The second solution is to change out the mixer to a thermostatic shower valve. Obviously not as cool as the mizer but done right it looks really good.
Third is to add in a back flow valve to the water lines. This looks super easy and is the cheapest solution.
Wondering what anyone on here has done this, and if their is any other solutions I have not found.
