Upselling before installing (Insurance required) Moen shut off valve.
I had plumbers come to install the Moen shut-off valve. They tried to charge me $900 more and said the shut-off valve and pressure regulator I had just replaced had to be replaced. Both the valve and regulator were a couple of weeks old. He said he would not warranty having to re-solder something... Essentially, they are trying to force me into paying to replace something that did not need to be. It was an upsell and, from other reviews, seems to be common practice for the Moen shut-off valve installers.
