A series of recent incidents of plumbing leaks in the community are the reason for this alert.
The following are two examples of the types of leaks that have occurred:


UPDATE
Based on the advice of the above homeowner, I had a plumber in to look at possible trouble areas in my own home.
The plumber advised that the plastic water supply lines pictured above sometimes fail at the connection to the shut off valves. (A plastic ferrule which holds the connection together slips off.) This is what happened to the above homeowner.
Accordingly, I had the plumber replace the following plastic water supply lines with braided stainless steel connections.
– 3 bathroom sinks
– dishwasher
(kitchen sink already had a braided stainless connection)
He also checked the toilet connections, but he saw no reason to replace them. Also, the toilets have metal supply tubes which leak slowly into your basement when a problem starts. They don’t destroy your house without warning.
Shut off the main water valve when leaving home for an extended period of time.
The photos below show the main shut off valve.
The first one shows the shut off lever vertical in line with the water pipe (this is the “ON” position).
The second picture shows the shut off lever horizontal to the right (this is the “OFF” position).

To turn “OFF” turn lever clockwise until it stops (only turns to the position shown in the picture).
To turn back “ON” turn lever counter clockwise to vertical position.
