Overpriced and lazy. 8 months ago, a Roto Rooter plumber came over to my house to check the pressure on my gas pipes to see if it was possible to have a gas stove. He spent 30 minutes checking the pressure and it didn't even hold pressure for 1 second (should have been a hint!). He was happy to charge me $250 for doing nothing and left. Fast forward to today, I was doing some maintenance on my furnace and I looked up. I saw a dead end gas pipe that the end was completely opened and not sealed off! In open air in my basement ceiling! I traced it back right to the line that would go up to my stove. I feel so foolish now for letting him take advantage of me like that. I already bought an electric stove and now it's possible that my gas-line can hold pressure and now I have to test it again. It should have been a dead giveaway that it didn't hold pressure for even 1 second.
AVOID at all costs. Don't make the same mistake I did and throw money down the drain.
