Trying to install a sump pump discharge line by your self but not sure how deep it should be. In this post our team well outline how do you different types of discharge pipes need to be in order to properly drain sump water.
Installing your drain line at the wrong depth and not digging your trench deep enough can have disastrous results like a frozen line, a flooded yard and lines that do not completely drain.
While drain lines can also be installed above ground it is more convenient to dig a trench and set them up below your lawn. Keep reading to learn everything you need to know to dig your pipes to the correct depth
Discharge Piping Depth
You should install your sump pump discharge line 2 feet below The frost line in your County. This will help prevent the water in the pipe from freezing and causing clogs while still making it easy to dig and access the trench in case there are any problems.
In most areas this means the lines should be buried 2 to 3 feet underground in most parts of the United States. If the pipes are not deep enough they may freeze during heavy snowstorms.
Digging the Trench
Drainage trenches can be dug by hand or using a trench digging tool. Follow these step by step directions to dig your trench and correctly install the lines.
- A shovel or trench digging tool – If you need to dig a trench longer than 5 feet we recommend using a trench digger or else it will take a few days
- A measuring tape – A measuring tape can be used to track how far you have dug
- A tarp to pile the dirt onto for reburial
Digging the trench can be easy – or difficult depending on the soil, depth and the trench length. Start digging from the where the discharge pipe exits the home and end as the drain point.
Make sure to dig and lay the PVC pipe at a slight downhill so the water drains easily from the pipes. If it has to flow uphill and work against gravity you will need a more powerful sump pump.
