A percolation (PERC) test is used to determine the ability of the soil to absorb and filter wastewater from a septic system. The ideal time of year for a PERC test depends on various factors, such as weather conditions, soil moisture content, and vegetation cover. In general, the best time for a PERC test is during the dry season, when the soil is not saturated with water.
In most areas, the dry season occurs during the summer months, making it an ideal time to perform a PERC test. However, in some regions, the dry season may occur at a different time of year, and it's essential to consult with a licensed septic system professional or local health department to determine the best time for a PERC test in your area.
It's important to note that PERC tests must be performed by a licensed professional and may require permits from the local health department or building department. Contacting a licensed septic system professional well in advance can help ensure that the PERC test is scheduled during the optimal time of year for your area.
