Its built from the barrel bushing using the $18.95 adapter. But, heres the fun part. Both pieces need to be worked and fitted. Takes over a day to marry them with the barrel for a perfect match. I'm selling the two piece adapter for $400.
I contacted you maybe a few years ago about the USAS-12 if it was still available for the sake price, I got a buddy on social media that may be interested if you are still trying to sell it.
Thanks for the question. The problem was the recirculation pump had seized due to either weather conditions or natural failure, the technician said. So, $500 later and no hot water for 5 days the part was replaced. I investigated what could of caused the problem which I determined the ceramic washer had shattered in the unit, locking up the shaft so the motor would not turn.
