Heater auto drain?

[Plettschner]

Goofy question for the day...

When not using my heater, I plan on leaving it bypassed but concerned about water just sitting inside of it. I may even automate the bypass valve so that when heater is not active, it automatically is bypassed.

I know I could automate a drain valve, but I'm thinking an air vent into the heater manifold may be needed for it to drain. Small vent/check valve on a T fitting where pressure switch is (top of manifold)

I think you are over designing things.

What do you think the water sitting in the heater will do?

 

[Plettschner]

Yes! That's me! I tend to overthink everything

Not really sure what it will do. Cause corrosion? Turn mucky? Ok, maybe I have a solution looking for a problem.

It will do nothing bad. And when it flows into your pool it will be a drop in the ocean.

You should run your heater once a week for best life. It reduces corrosion and keeps spiders and rodents from nesting in an idle box.

Yea I don’t know about draining it, I would be scared of the Copper oxidizing. But bypassing isn’t a bad idea, I don’t know the benefits except water restriction maybe. The new Jandy Jxis have an automatic bypass built into the manifold.
