| water heater installed right?
I just had a replacement A.O. Smith water heater installed by someone recommended by a contractor friend. The installer brought an apprentice to do the work, supervised him--I thought. But after they had left I noticed solder dribbling down the incoming and outgoing water pipes (about 3 inches or so, ugly blobs) and solder drips on top of the water heater. Plus other minor indications of a sloppy job. It doesn't leak, but it looks bad.
They also used adhesive aluminum tape around the connection for the exhaust pipe. I've purchased a similar tape in an auto supply store and wasn't too happy with it. One step up from duct tape. Can it be all right to use on a heated appliance?? How long can it possibly last? I assume there's a more solid connection under the tape. The old heater had a sheet-metal to sheet-metal, riveted connection between the heater and the exhaust pipe.
I tried to whack off the solder with a hammer and chisel, but no luck. The installer says he'll come back and clean it up. Should I object to the tape too? This wasn't a cheap job, $830 for a 50-gallon, non-conservationist tank. They used the same plumbing as the old heater.
Thanks to anyone offering insight. |

Sure it could have been a little neater but really it's ok. That tape is standard fare now.
Oh, if it was me I would stop chisseling off those dribles now. You're really looking for trouble there. |

I'm sorry, but I have to disagree with mityfowl  about sloppy work being "normal". I take great pride in my installations, including work I do in attics, even if no one but me ever sees it.
If you're not happy with the job, I'd recommend calling the contractor and telling him you're not happy. Aesthetics is important. There's nothing wrong with using an apprentice. How else are they going to learn, but if he did a sloppy job, he needs to know.
As far as the aluminum tape being used on the double-wall vent pipe, I'm pretty sure that's a code violation and would not be allowed by The National Fuel Gas Code. If the vent pipe is installed correctly, there is no reason to use aluminum tape.

| I don't see the fact that the solder dripped down indicating the job was done in a sloppy or unworkmanlike manner. Now if the copper were kinked or they made a 3" hole through the ceiling for a 1/2" pipe it would be a different matter. Solder sometimes dribbles and even drips (the solder on the top of the tank should be easy enough to clean up).
I'm not a plumber but I don't think the aluminum tape would be a fire hazard. It certainly would help prevent minor vent leaks. Perhaps one of our plumbers will chime in on this issue. |

Your quality of work will get around. It takes very little extra effort to ensure a neat job. Even on the hidden work behind the walls. |

Found this on a DIY site.
The last step is to wipe the joint. With an old, old rag (which you're going to throw away and never use again), perhaps moistened slightly, folded to several thicknesses to protect your hand from this very hot pipe, quickly wipe the excess solder and flux away. Your goal is a bright, clean, shiny joint, with clean copper on both sides and a little band of silver-gray right at the joint, with no big blobs of solder or streaks of flux. You might imagine you can skip this step, because an unwiped joint doesn't look too bad at first, either, but a few weeks later, the residual flux will have corroded the exterior of the pipe and left ugly green streaks. (Also the greasy flux residue will be impossible to paint, if it matters.) |

I think SandShark knows what he's talking about. Ugly joints are, well, ugly. |

The joints should have been wiped but there really is no issue if it is not - it will not corrode the copper or anything else - it is only a 'problem' with looks and nothing else. I certainly would not use it as an excuse not to buy a house or anything like that.
The installer offered to come back and fix it up - no big deal and what he should have offered (rather than blowing you off which is what they could have done).
For this reason - I usually have my plumber to this type of work rather than deal with contractor roulette at any big box store (Blue/Orange box).

If it's just an aesthetic issue then why not insulate the pipes? It'll hide the dribble and improve the heat retention of your pipes leading into and out of the unit. |

Thanks to all who replied. I'm more concerned about that aluminum tape than the solder dribbles. Will check out whether the tape is OK by the Code. And that's a good idea about covering them up with the pipe insulation.
But still, since cleaning up the dribbles would have been so easy when they were still warm, why didn't he just do it? So sad about the state of craftsmanship today. Glad to see there are still a few craftsmen still at work; the trouble is to find them. |

Thats called flue tape and yes, that is what it's designed for. I've used it on stovepipes on indoor free-standing cast iron wood and coal stoves. Using it on a gas hot water heater is allowed, the adhesive sets with exposure to high temp, and as long as you dont try to remove it, it sets up and provides a really good seal on leaky flue joints.
Think of it as extremely high temp duct tape. I even used it to patch a cars rusted out old muffler (just before I sold it) to keep the noise down. Works well, just dont expect longevity when exposed to the weather.

That's useful information, however, on a gas hot water heater there is absolutely no reason to be using any kind of tape on the vent, especially a new installation.

The tape is OK according to the National Fuel Gas Code. It's nice to know why--thanks, Cheese. Roses to Sand Shark for his high standards.
I had uploaded a photo of the job but it didn't show up. The tape is wrinkled and looks amateurish, but not as bad as the drooling solder. (And hardy har har, mityfowl, about my wanting to pull the permits and tags.)
Thanks again for all your helpful insights and amusing putdowns. DSL reports is the best website on the entire Web, IMHO.
BWT, I was astonished that this thread showed up already on Google, at the top of the list, when I entered the right keywords. |

| No irked there was another thread, I think it was in the suburbs of Chicago, where the guy DID get fined from the city for not pulling a permit for the water heater he bought either at HD or Lowes. Cost him about $400 extra for that!
Glad it worked out ok. I would like to see the pics too if you get it worked out. |

Yes Google does a great job of getting content on popular forums up to the top of search listings. I'm not sure what the reason is but I see it happen all the time, and not just on this site. I think because it could be more likely to be real content and because they know its very fresh.
It's actually a great way to get a message out. Say "john smith plumbers" installed a water heater incorrectly and it blew up and you want to warn people... start a thread "John Smith Plumbers Blew up my House!" and anyone that searches google for "John Smith Plumbers" will find that probably at the top of the 1st page of search results.

2 edits | Tape is NOT certified by NFGC.
There is no tape certified to hold to 400°F, this is why.
If one of the joints has to hold any weight of the pipe, and the tape lets go, the flue line will fall off and fill the room will combustion components. Then we have dead or sick people.
Sheet metal screws or rivets are the only certified method of securely joining flue pipe.
As it was mentioned before "tape is good for a leaky flue" NOT.
Chimneys operate on -.02" of water column, plus or minus -.03. If the chimney cannot provide enough draw, and hot gasses can be felt either at the joints or at the flue diverter, there is a problem. Metal flue line needs no seals.
Yes I am a licensed plumber.
