Can I add a line to an HRV?

I have an HRV and an unfinished basement. In the basement, there are no HRV lines that directly bring in fresh air or exhausting air, but the HRV unit is in my basement and the HRV ducting is accessible before it goes elsewhere in the house.

If I wanted to have the HRV also work in my basement, is it just a matter of tapping into the existing lines? As if I was adding a water line? Is it DIYable?

You would have to get the HRV re-balanced after you add the new intake/exhaust.

Speaking of HRV. I have a HRV pre-installed in my house.

I can hear the motor and the fan are running fine when I turn it on. As you know, the HRV air flow is very subtle.....which is hard to feel especially the air flow is all from my hard-to-reach 9 feet ceiling grille.

How do I actually check to ensure my HRV is working up to the standard?

Check your filters and exterior grills are clean
Get up on a ladder and check for airflow at ceiling grill?
Those are basic checks if the unit is operating
Youd need to get a professional in to measure the airflow at the "standard"

Ideally, you would interlock the HRV with your furnace fan to help distribute the airflow.
