PRIVATE WATER SYSTEMS - Piping - Protection

Protection

If the piping in not installed deeply enough, the water may freeze in the piping system during cold weather. This will either block the pipes, or burst them. Pipes also need to be protected from mechanical damage caused by tractors, cars, and large animals.


Protection From Freezing

Protection from Freezing The pipe installer should know the commonly accepted depths for placing pipes underground for the area.


stop-and-waste  valve Pipe lines not in use during the winter months should be drained. Using a stop-and-waste valve for a cut-off in the supply line should take care of the problem. When the water is turned off, the valve automatically opens the waste port. Water from the non-pressure side of the line drains into the the rock-filled sump around the waste outlet. Faucets must be opened to allow air into the pipe and insure complete drainage.

Insulation
Electric Lift
Provide either insulation or electric heating tape and thermostat if the supply line is exposed to freezing where it passes from the ground into the pumphouse.

For hose connections in unheated buildings and for outside use, it is best to use a frost proof hydrant. To avoid possible contamination caused by water from outside the hydrant flowing into the supply line while the drain port is open, install a drain line that will allow the water to drain to an open outlet at a lower level.

Protection from Mechanical Damage

Places for Pipes Avoid putting a water outlet where cars, trucks, or tractors, may run into them, or where livestock can have direct contact with it.

Where possible keep the outlets on the opposite side of the fence from livestock, or mount them along a post or other permanent protection.

If plastic pipe is in shallow trenches, it is a good idea to provide mechanical protection where it extends under driveways. Heavy vehicles passing over the pipe can force a sharp stone or metal object through it if it is not protected. Placing the plastic pipe inside a steel pipe will certainly provide the necessary protection.
