Hi all,
I recently purchased an Amtrol expansion tank. I'm hoping someone familiar with these tanks can help me with a problem I've run into.
I purchased model ST5:

Amtrol has a unique (?) part that installs in the incoming water connection called a "turbulator". I have attached a photo.
The instructions state to: "Press Turbulator fully into connector prior to installing tank." The included illustration (attached) shows the part fully inserted up to the top of the ribs which prevent the turbulator from going inside of the tank. Link to instructions here:

However, when I insert the turbulator into the tank, it only inserts about halfway - well short of the top of the ribs. I have attached a couple photos. As you can see, the turbulator is tapered and is too large to insert any deeper into the tank.
My guess is that I either have an incorrect part (turbulator is too large and meant for a larger model) or the instructions are incorrect (turbulator does not need to be fully inserted on my model).
Does anyone have experience with this particular model (ST5)? What's the deal with the turbulator - should it in fact fully insert into the tank's opening?
Thanks for reading
EDIT: to answer my own question - it seems that the turbulator part is manufactured a bit too large for the opening in the ST5. It can be forced in, which scrapes just a bit of the plastic off the sides of the part. I had to turn the tank upside-down and push it on the ground to force the turbulator part inside as designed. I could not push it in by hand. I would consider this a small manufacturing error on the part of Amtrol; in my opinion, the turbulator should easily slip into place.
