12 mths of use on a daily basis, no problems.

"Maybe I trapped some air and over pressurized the bladder."

NO , air compresses so is no problem , expanding water just keeps getting to a higher pressure , so blowout.

Winterizing be sure to get to the sink diverter valve and hand spray , theycan freeze and leak too.

Dont ask!

Air compresses but if pressure in the tank exceed tank maximum the tank will blow. Not sure what is the max pressure for these tiny plastic tanks but should not be very high.

If the accumulator tank is mounted incorrectly with the filler top most then it cannot drain. It also will not blow out.

That means water will stay in it almost full. Even though you winterize there may not be enough A/f to fully protect it so it freezes.
Even though one would think the pressurized bladder would push the water out maybe it cannot do so enough to prevent damage.

When it freezes the result is a burst accumulator.

Remount the accumulator. It may need some different fittings and a bit more hose but better than bursting the unit. But the outlet/filler needs to be the low point.

Of course I could be all wet.

In Pack Mule's post #7 he indicates the pic is upside down. IOW, his units are mounted correctly.

Maybe I wasn’t clear.Mine is mounted opposite of the picture with the bladder facing down . If I have enough room under the deck for the bladder to face up , I could just flip the whole unit over .

Yes, bladder facing downward -- i.e., Schraeder valve underneath -- is correct.

For other readers, I just told Marty in our PM exchange that I probably really should have instead said that his mounting position is workable and apparently not uncommon. I don't think there's a mandatory orientation. Jabsco's literature shows the accumulator mounted one way, the pump another, etc... Happens ours is mounted like his, too, likely a builder's decision based on PEX routing and overall mounting considerations for the three-piece unit, strain relief, and so forth (just guessing).

Another point is the expansion tank does not have to be located near the pump or HW heater.

Any place in the FW line will work , perhaps in a different location a larger bladder can be used.

We mount the house style tanks with the water hookup on the bottom , aith quality SS reinforced hose.

To winterize , the hose is simply disconnected and the tank drains.
