If you’re going to be installing a septic tank in the future, there is a good chance that you’ll need to perform a perk test. Depending on where you live, you may be able to do this without a professional. However, some jurisdictions require consumers to hire a professional to perform the test. Therefore, you’ll need to do some research before moving forward. To perform the test, you’ll need to dig a few test holes, saturate the oil, and perform the test. It is a good idea to create a table for the results so the information will be easily presentable.
