THE THREADS CRACK AND SEPARATE AFTER LITTLE USE ON THIS MODEL. WE HAVE NOT BEEN ABLE TO FIND A REPLACEMENT PART NO. 44 PART ORDER # 6884890440. CAN YOU HELP US. WE PURCHASED NEW AS CHRISTMAS PRESENT AND FOUND THAT IT DEVELOPED A LEAK FROM THREADS THAT CONNECT REGULATOR TO THE HOSE ATTACHMENT THE FIRST TIME WE USED IT. THANK YOU.
