Can you backwash your pool into the street?

For many areas, a green pool cannot be pumped into the street or into the storm drains. Most cities restrict this practice to clean and clear pool water only. Some cities such as Phoenix require you to pump into the sewer cleanout of your home.

How long should you backwash a pool?

Open the air bleeder assembly on your filter and turn pump on. Watch the pressure gauge for spikes. After the hose fills with water, backwash your sand filter for 2 – 3 minutes, or until water runs clear.
