Ace Pelizon Plumbing found 1/2 nipple and 90 corroded. Will need to dig around gas line and then attempt to remove 90 and nipple. Once removed will install new 1/2 90 and 6†nipple. NOTE: this is an attempt no guarantees that I can get 90 off horizontal pipe. If this does not work will need to replace gas line. Ace Pelizon Plumbing removed gal 90 and nipple and replaced with gal new tee, gal nipples and gal caps.
