Water leaks can cause tremendous damage costing tens of thousands of dollars or more (depending on your particular circumstances) so it's important to do what you can to prevent them. Following are 2 simple things you can do to that end.
First, install self-contained water systems (bottles) on all of your delivery systems and disconnect them from your municipal supply. That way, if you get a leak, you'll be limited to the capacity of the bottle in volume. A leak of a liter of water (or 2) is going to do a lot less damage than hundreds of gallons from a continuous municipal feed. Of course, there are a lot of other benefits to self-contained water systems which we don't need to get into now.
The second thing you can do (and which I also strongly recommend even if you use bottles for the units) is to put a solenoid on your main water line into the dental office. Even if your units aren't connected to the municipal water supply, you'll still have bathrooms, break rooms, a sterilization area, and other things that may have sinks or toilets connected to the city water. These things too can fail and cause extensive damage if not caught in a timely fashion.
Statistically, your office is closed for more time out of the week than it is open, so a leak is more likely to happen when no one is in the office. For a few hundred dollars, you can have an electric solenoid (shut-off) installed on your main water line so it's easy to shut the water to the entire office off at the end of every day. Have a switch for it installed near the staff door so it's easy to shut it off before leaving the office.
It's also important to get a manual by-pass installed with the solenoid as most solenoids shut OFF when they fail. If the valve should happen to fail while you need water (i.e. during business hours), it's important to be able to bypass it.
These 2 simple (and relatively inexpensive) things can save you from thousands or even tens of thousands in water damage.
