Draining dual water tanks

I am attempting to drain my water tanks and would bet much appreciate any assistance. We have a dual water tank system. Our main tank is a hybrid water tank. We have a A O Smith water tank hooked to that tank that pulls from the hybrid and stores hot water. I have drained the hybrid but am unable to get the A O tank to drain. Any assistance is greatly appreciated. Thanks much in advance.

What happens when you open the drain valve?

Nothing happens. It doesn't drain at all.

Welcome to the forums.

Usually you need to let air in to the tank for it to drain.....otherwise the tank is under a vacuum.

Welcome Jamie!

The first thing you can try is to open a hw tap or loosen a union above the tank if yours has one.
It is possible the water will not empty because of not having any air being allowed to replace of a vacuum.

It is also possible that the drain valve is covered in scale.
If your tank is in an area where water can get on the floor and a catch basin nearby you could remove the valve and prod the tank with a rod of some type.
Another thing to try is to try opening a hose bib outside and hooking up a garden hose to the drain valve.
If you run water through the hose and valve it will likely push the scale away from the opening allowing it to drain.

This is how I drain my tank on a slightly hard well.
It does an amazing job of getting everything out.
