There are valve lock out devices available

Hello,

Kris, we hope yoyur mother is doing well. I think her operation was about now.  A big surgery when you are older.

We have seen that merely turning the valve to restrict flow is not working. Its too easy to reverse it.

I Googled valve lockout devices and there are lots. Here are some of the links.

The other option is to revisit the definition of "restrict".

There could be a case for turning it off completely for certain hours and then back on the rest of the time. The advantage would be its either on or off not someplace in between that is uncertain.

Of course we need to follow the law per our attorney.

All the Best,

Steve
