Upon arrival customer informed me that they bought a Moen shower valve that they would like to put in place of the current. Current valve is working but has a slight drip. Very minimal. Customer has a Moen repair plate kit on the shower behind the bathroom in question. I advised customer they would need to have the same repair plate if they wanted to avoid cutting the wall too much. I explained to the customer what I would need to do to access the valve with working space on a back to back shower. I told customer that plumbing wasn’t magic and there is a complex install process. Customers wife said she was not going to pay anything close to that and to send her an email. I asked the customer who they were thinking using as an alternative and maybe we can match the price. Customer said God!
