Turning OFF your water
Depending on how your system receives water will determine how you turn off the water. Your system will normally be supplied in one of the following ways: tap, plumbed, or a pump.

Connected to Taps
There are 2 different types of taps.
Taps that have a valve in the basement (older) that shutoff the water to the tap. We need the client to turn this valve off.
Taps that turn off the water inside (newer) the heated area of the house do not have a shutoff valve inside the house. We can turn these off ourselves.
See examples below
Connected to taps
By default we leave the pipe connected to the tap. We do not disconnect pipes unless you advise us in advance.

Connected to Plumbing
If your system is plumbed directly into the plumbing of the house, you will have a valve that shuts off all water to the sprinkler system only. We need the client to turn this valve off.
See examples below

Connected to a pump
There are 2 types of pumps we come across.
Pumps that are installed in a well, used only for irrigation. Pumps that are installed in rivers and lakes.
For winter, the safest course of action is to turn off the electricity to the pump. We need the client to turn off the electrical breaker.
