In Jet’s laboratory testing the Jet system handled an additional 100% load for an entire week without any adverse effects on the system or its performance. However, if you are concerned about a large party, such as a wedding reception, being held at your residence you can arrange for a tank cleaning and pumping just prior to the event to ensure optimal treatment capabilities of your Jet system.
