Welcome to IRV2.
I would definitely look into Rettrobands and Proteng. We had both installed when we picked up our DS. The peace of mind is priceless.
Make certain that the shower in the master bath is working properly, including the aguamiser. We had an issue with the mixer cartridge that was an easy fix once the issue was identified.
