Question

expansion tank position


is it better to have an expansion tank right side up or upside down? or does it even matter.

i've seen them both ways

As long as the drain valve is in position to drain the tank.

Most small expansion tanks have no drain--only an air valve for the bladder--so it makes no difference with that type---

The old style big ones with a drain need to have the drain down ,obviously.

Agreed that it does not matter. Two things to consider. Installing it in the upright position will require less fittings. If you install it in the upside down position, you'll have less water dumping out when you remove it, but it will take more fittings and you'll likely have to do more work to support the thing.

I prefer installing them upright directly on top of the cold inlet.

I like them above the fitting so that any debris or particulate matter circulating in the system doesn't collect in the expansion tank.

Bladderless expansion tanks must be installed above the pipe. Tanks with bladders (diaphragms) can be installed in any position.
