Don't hire them for anything gas related unless you want to damage your appliances and possibly have trouble passing inspections later. I tried getting other plumbers to fix their mistakes but refused to work on it because they thought stuff could be broken and didn't want me to blame them. Three separate plumbers saw their work and politely told me to never hire them again. I was willing to let what they did slide because they were friendly and seemed to want to make things right, but they ghosted me so I figure I should warn people.
The main problem is when I upgraded my gas unit to a higher pressure, the gas company told me to make absolutely 100% sure there was a regulator between the unit and the house or my appliances could be damaged. They went on to say that if the plumber I called didn't think it was necessary to find a new plumber. I wish I had listened. I called this plumber and they explained to me for 20+ minutes how a regulator wasn't needed, and how dare the gas company try and scare me, etc. I repeated what the gas company told me in 5 or 6 different ways, particularly that pressure was going to increase by 4x. The plumber told me that a regulator wasn't necessary, appliances won't get damaged, appliances have their own regulators, etc. Literally a 20 minute conversation of back and forth. I decided to trust the plumber because he sounded supremely confident. Gas pressure was upgraded. Appliances stopped working. Found out later they could have been damaged. Called the plumber. I think they realized they messed up and the plumber called the gas company. Gas company showed up and removed the upgraded unit because apparently it was so dangerous it's not even allowed. Sanchez eventually came back out, put in a regulator, but when the gas company came back, they said the regulators weren't even facing the right direction and could easily get water inside of them. If it froze, my gas lines could seize up. The gas company guy was supremely polite and diplomatic but he basically said this was a brain dead mistake and would take 10 minutes to fix. He also wasn't sure if such a positioning was even to code.
Like I said, maybe they're good at water, but don't trust them for gas. I need to call another plumber to come fix the regulators and cross my fingers that my water heaters and dryer don't have any subtle damage that would take years off their lifespans. Oh yeah, and they ghosted me. I texted them 3-4 times over the past month or so and nothing.
If you're the owner, don't message me. I want nothing to do with y'all. I'm going to tell literally everyone I know to avoid y'all. I'm going to tell the person who referred me that he's screwing people.
