    Why I love installers...

    This is from a large York RTU that has been in service now for oh, 6 or seven years. On 12/1, I was sent to do a heating inspection for this store, and found a rusted HX. During the disassembly, I found that no one had used any pipe dope on ths fitting during the install.

    It was finger tight.

    So, I get it all back together, and I'm ready for the burn-off. On the initial visit, the unit had fired, but not well. Due to the bad HX, it could not be operated long enough to fully delve into whatever problems might be present.

    I get out the Testo and find the gas pressure to the unit is not what it should be.

    I look at the regulator, and find the setting was screwed down ALL the way, in an effort to get more gas into the unit.

    Now, it has a nice new one. Not screwed down to the bottom, either.

    Maybe these guys are a necessary part of the industry, to keep the rest of us working. It still bothers me, though.

    that street elbow looks like it would have been done at the factory. not making an excuse for the installer, that's part of the startup but just saying.

    Im pretty sure the street ell on that unit comes factory, still it should have something on it.

    Also on your new regulator, you gonna put a proper vent on it or buy a maxicap?

    That is scary. They are either so cheap or lazy that they can't spend the extra few minutes to use pipe dope...

    All they would approve is a like-for-like replacement. Same part number, same method of install, no extra parts.

    Like most of our customers, it's a chain store that is contracted through a third party service broker.

    You dont actually need pipe dope to make a leak free joint. The pipe dope is more of a lubricant than a sealer..... If you ever get into a court of law over pipe dope....you need to remember that...

    It is the threads grinding into each other that is supposed to do the sealing.

    The pipe dope allows you to make up the tapered threads easier.

    Yes... Im sure pipe dope does have sealing properties at low pressure....but so would any kind of "goo".

    But it is the tapered threads and the tapered fitting that do the sealing as they are forced together.

    Where pipe dope and teflon tape does help are on some unions and on those god awful non tapered pipe couplings that come on the end of threaded and coupled pipe but if you have used those cheap ass unions or those all thread couplings you probably know that sometimes nothing at all will help until you replace with a decent fitting.

    I dope my pipe according to the directions on the can.... its way too much pipe dope to the job but I do it that way in case there is ever a problem and then I can truthfully say I applied the dope according to manufacturers instructions.

    I would think that any spring would be fully compressed with the adjuster screwed all the way down. I could be wrong though.

    New one works great.

    I know how those third party service people are, we also take care of national chain stores. Some national chains are great for service, will fix anything, some are so damn cheap.

    Still needs a proper vent on there, the brass limiter isnt for outdoor use and will let water in.
