Need help. You can clearly hear when a valve is opening to let air out when i turn off the engine and close the door. It lowers to a certain height. And then by next day the car is lowered to the ground

The lowering to a certain height is normal.

The abnormal part is leaks that cause the car to be on the ground over night.
The most common issue that causes that is a small leak in air bag at the fold.
Especially in air bags that are 10 years old or older.

Diagnosing with a soapy water spray would be recommended.

Normal function of the system
Checking for any leaks would be in order.
Open the trunk and shut off the air suspension via the switch in the trunk then jack up the rear of the vehicle allowing the axle to dangle.
Once the airbags are stretched out inspect the very bottom of the bags for cracking and spray them down with soapy water.
IF you see bubbles then replace the bags

You did not state the bags were brand new. Don't understand why you would not state recent repairs to the very system that is having issues.
May not be a bag leak. Maybe an O ring leak. Or something else.

And the diagnosis is the same with soapy water.

The other question is why replace good parts?

I replaced a noisy pump, and thought to have a better ride with new bags

Same diagnosis, soapy water spray the entire system.

If you have car ramps this would be an easier approach to getting the vehicle off of the ground to get under it. And still maintain a load on the air suspension system.
In addition, you just might be able to hear the air leak hissing. If not, that spray bottle with some water and liquid soap will be your friend.

Good luck. Post back your result.

A leak following replacing the airbags almost always is a solenoid o-ring issue or possibly the airline collet at the solenoid.

Did you reuse the original solenoids or use new solenoids supplied with the airbags?

If you reuse the original solenoids, it is imperative to put in a new o-ring kit.
