asihi Posted July 26, 2010 Report Share Posted July 26, 2010 Over the weekend we had some torrential rains, upwards of 7" overnight on Saturday. I just got a call from a client canceling an inspection that we had scheduled for tomorrow because the basement of this house he's looking at was flooded. He didn't go into details and couldn't talk all that long, but he did say that there was at least 8" of water all the way around the basement and he wants to re-schedule for later in the week after the clean up. Here's my question; this is a large home with at least 2 boilers and multiple water heaters. If these systems were buried under water, do they need to be replaced or can they be dried out? I would think at a minimum, the burners and control valves on all of them would have to be replaced. Thanks for your help. Tony Quote Link to comment Share on other sites More sharing options...
Terence McCann Posted July 26, 2010 Report Share Posted July 26, 2010 Hopefully they got a pump in the basement and got the water out quickly. The only thing I'd replace is the electric/electronic controls that were under water. You can reuse the burners. If it's a finished basement they should be replacing drywall too.

Jim Katen Posted July 26, 2010 Report Share Posted July 26, 2010 They should remove the bottom 2' of drywall from the entire basement and have a half dozen fans running till it's dried out. They should hire a real drainage contractor to design & install a real drainage system so that this doesn't happen again. They should replace all NM cables that got wet. If the boiler or water heater controls were underwater, they should be replaced. I agree with Terry that the burners are probably fine. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...

Disaster restoration was once my business and there's no way you can possibly dry that wall cavity fast enough to avoid fungal growth without yanking the drywall AND the insulation and then, as Jim says, get those hurricane fans going.

asihi Posted July 26, 2010 Author Report Share Posted July 26, 2010 From what I understand it's an unfinished basement. Also they're not sure if the sump failed or if the sewer backed up. My only concern with the burners is being able to clean out the silt or whatever debris got in there. Quote Link to comment Share on other sites More sharing options...

asihi Posted July 30, 2010 Author Report Share Posted July 30, 2010 Just to close out this thread, I was at the building yesterday. These were 2-75 gallon Rheem water heaters. I called Rheem and they told me that the water heaters should be removed and replaced, not repaired. I guess that they were worried about the integrity of the tanks (water getting trapped in the insulation around the the tank causing corrosion) and of course the burners and controls.

Terence McCann Posted July 30, 2010 Report Share Posted July 30, 2010 I'd say that too if I were Rheem / rep. Quote Link to comment Share on other sites More sharing options...
Marc Posted July 30, 2010 Report Share Posted July 30, 2010 Terry's got a point. It might be more of a CYA measure. Marc Quote Link to comment Share on other sites More sharing options...
Neal Lewis Posted July 30, 2010 Report Share Posted July 30, 2010 If they have the FVIR newer technology, the manufacturer will recommend replacement if the flame snuffing safety device at the bottom gets wet. Only takes a few inches of water. Quote Link to comment Share on other sites More sharing options...

If they rust up, they might not work. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
mgbinspect Posted July 30, 2010 Report Share Posted July 30, 2010 I'd say that too if I were Rheem / rep. Before I had finished his recap, I was already having the same thought. I suppose a corporate attorney could be thinking of eliminating possible liability on someone else's nickel too - Let's take a ride on the Home Owner's Insurance Company! Yes!

Terence McCann Posted July 30, 2010 Report Share Posted July 30, 2010 It also boils down to selling units. I must amend my statements. In a normal world, where people take responsibility, there is no need to change the unit. Given the present state the only correct action is to replace the tank. We live in an time where people can not, for the most part, think responsibly, intelligently or mechanically. The minimal amount of prudence that would go into making sure a hot water tank, that has been under water for X amount of time, stays safe is actually beyond most people. Perhaps not beyond intelligence but surely beyond extending any extra effort. As most know I take very little seriously but in this case the best thing to do is recommend replacement. It's the only way to take the "idiot" out of the equation. Quote Link to comment Share on other sites More sharing options...
