How far below frost line should water lines be?
12″
Water filled pipe should be buried at least 12″ below the maximum expected frost line. It is recommended that thermoplastic piping be run within a metal or concrete casing when it is installed beneath surfaces that are subject to heavyweight or constant traffic such as roadways and railroad tracks.
Should you run water to keep pipes from freezing?
When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe – even at a trickle – helps prevent pipes from freezing.
How do I protect my water pipes from frost?
Tips to help prevent pipes from freezing
- Insulate pipes. Pipe insulation in your home’s crawl spaces and attic helps even if you live in a climate where freezing is uncommon.
- Use heat tape or heat cables.
- Seal leaks.
- Secure outdoor hoses, valves and faucets.
- Let water drip.
- Adjust the thermostat.
- Open cabinet doors.
How deep do water lines not freeze?
The classic rule-of-thumb procedure for avoiding cold-weather damage to water pipe is “bury it deep.” If water lines are located below the lowest level of frost penetration—five to six feet or more in many cold region locales—they should be safe from freezing.
Can a water line be installed below frost level?
In certain circumstances it is virtually impossible to install a water service line below the frost level. These situations are not common, and in some instances other conditions exist that may freeze a buried water line solid. These are the 4 major reasons that steps have to be taken to prevent pipes from freezing that are buried underground: 1.
Why do you need footings below the frost line?
When water changes from liquid to solid, it expands 9% in volume. This resulted frost heave can be detrimental to footings and foundations. That’s why building codes specify structural footings be placed below the frost line. Additionally, water and sewer pipes need buried below the frost depth.
How to keep outside water supply pipes from freezing?
There are many ways to keep water supply lines from freezing when they can’t be buried below the frost line, but the trick is making it all happen reliably and with minimal electricity use. The first time I installed a Heat- Line product for one of my projects was back in 2011.
Is there a frost line in northern Ohio?
The frost line in northern Ohio is similar to Michigan. As long as the pipe sloap is enough to clear the pipe of standing water, you should be ok. Trapped water that freezes can expand and burst a pipe. With a drain pipe, the water flows out of it.
Do you have to put water pipes below frost line?
Water pipes should always be set below a frost line to prevent them from freezing in the winter. It’s also important that the footings for a building or a deck be well below the frost line so the posts don’t shift as the ground freezes and thaws. Check your local building codes to determine the proper depth past a frost line a footing should sit.

Do you know the depth of a frost line?
What is a Frost Line The frost line is the depth at which the ground freezes. It’s important to know the frost line depth for construction purposes. Water pipes should always be set below a frost line to prevent them from freezing in the winter.
