Arrowhead Brass 480 Series Vacuum Breaker Will Not Thread On Troubleshooting

     If the Arrowhead brass PK1390 (1019-A 486 BFP) breaker has never been replaced this job will require a pipe wrench, or a pair of good adjustable pliers. If you just grab the old breaker and take it off you will leave the collar of the old breaker on the faucet. See picture below to see what the collar looks like when it is still on the faucet. The collar will have to come off. Arrowhead brass uses sealant on the threads which makes it very hard to get off. The pipe wrench, or adjustable pliers should work for the removal of the old collar. Once the collar is removed, the new breaker will thread on.
