Fill-Trol Expansion Tank
Anyone here ever use a Amtrol Fill-Trol Expansion tank for their boiler rather than just a typical Watts ET-30?
I'm looking into them because they look like they might save me money since the Automatic fill valve, and check-valve are built in. It seems for $90 or so I can buy the Fill-Trol, or for $130 I can by a standard tank with a Watts Combo 1156F - 9D Valve.
I don't want to put it in and then find that there are major disadvantages to it.

I'm not 100% sure but I think the tank fitting is unique for that which might be an issue if the tank ever ruptures and you need to find a new tank quickly.
One thing to keep in mind is that you'll still need an anti-backflow valve. That Watts combo has one but I don't believe the full-trol tank does. I'd also spend a few extra bucks and get the bronze version B911S.

From what I've read and gathered so far on the Internet, the Fill-Trol valve has a 1/2" npt thread, so it should screw right into the bottom of the Air Scoop. Also according to the manufacturer in an email I sent them, it also eliminates the need for the backflow preventer.
You make a good point in the fact that if the tank does blow, I probably wouldnt be able to get a new tank locally, so I would have to replace it with a new tank plus the watts combo, which would certainly cost me more money. And now that I think of it, if the tank ever does fail, it would cost me twice as much to replace since it's all in one unit.

Fill-Trol
Take Who's advice. Fill-trols do require a special tee. The tee is 1/2" female pipe thread but the tank is not. When they work, they work well but every one I have trouble with gets yanked out & a standard reducing valve & extrol goes in it's place. If the tank goes bad, especially on a weekend, finding a replacement fill-trol tank is not nearly as easy as a regular extrol.
