Siding nails shot into the backside of a panel
Garet replied to Stefan McGuire's topic in Electrical Forum
I'd find the siding guy, give him a buck and ask him to buy me a lottery ticket. -
I've run across about a dozen cases over the years whre a GFCI showed proper wiring at first w/ 3-light tester, tripped normally, but showed hot/ground reversal after resetting. Bizarre. I can't fathom how this could happen. In every case it tripped again and reset properly the second time. I'd love for someone to explain to my how this could happen.

My current laptop power supply has 3 prongs, but all of my previous ones have had only 2.

A simple, cost effective solution is to put 2-prong receptacles back onto the 2-wire circuits. Having a grounded circuit does nothing to protect your fancy gizmos. The house will be just as safe as the day it was built. However... If you have anything with a 3-prong cord (like a surge arrester - hint, hint) then it needs a GROUNDED 3-prong receptacle. It may be easy or difficult to upgrade an individual receptacle, depending on many things. Get an estimate from an electrician.

Why is this myth perpetuated? I've never seen anyone produce a case where an inspector was sued for missing one code issue because they chose to reference the building code as the source for their opinion on a different code issue. If it's happened I'd love to hear about it.

I'd be looking for dust clogged on the heat exchanger coil. That might take some amount of disassembly.

Power Vent Exhaust Clearance To Direct Vent Intake
Garet replied to dtontarski's topic in Plumbing Forum
Examples: 1) exterior air intake into return HVAC ducts (we're seeing a lot of these in new construction and tight houses), 2) air-air heat recovery ventilator, 3) make-up air inlet for large kitchen exhaust. -
Well I'm glad you mentioned the smoke alarm. I was just about to put out a report that said some smoke alarms are missing. Now I realize the gizmo on the ceiling wasn't part of the Nest thermostat. I've got a Honeywell wireless T-stat an like it just fine. I wasn't looking for a 'cool gizmo'. I just wanted to be able to turn the furnace back up from vacation hold in time for the house to be warm when I get home (actually, by the time the WIFE gets home).

Nachi Certification Exposed
Garet replied to Paul MacLean's topic in Open Discussion Forum (Chit-Chat)
I don't find anything "new" about that formula. -
Thanks for clarifying. I sometimes forget that one. What I meant was the "No switches or receptacles within 36" of a shower" rule is a Canadian thing. Just send us your beer & hockey. Keep your electrical rules. Next thing you know we're going to start seeing panels mounted on their sides.
-
OK, so the guy meant 36", not 36'. Even so, there's no 36" rule in the NEC. It's a Canadian rule that continually crosses south of the border. Another example of continuing folklore in our industry.
-
Hint: for many (most?) models you'll find a "0" before the numbers that indicate tonnage.

bhapgood, Congratulations, you've already figured out what lots of builders refuse to believe: 1) water can enter masonry construction and 2) freezing water causes damage. I'd be happy to help, but with a 3 hour drive each way that would be an all-day job for me. For that much money you could probably just have a competent roofer install coping over the top of the walls to keep water out.

I just bought a 4-pack of CFL for $3.00 ($0.75/bulb). Give it a few years for the price to come down (like it did for CFL) and consumers won't want anything except LED.

It's not a house, it's a warehouse. I have a hunch that the building shell wasn't constructed with the intent to keep it as warm as Shayna 23 is attempting. If you "can see the outside light coming in through the mortar of the brick" then you're loosing heated air to the outside. First step is to stop the hemorrhaging. Unfortunately, your landlord has little motivation to address the issue since they're not paying the utility bill. If you really want to get a handle on things you need to have a knowledgeable pro look the place over. That's usually called an energy audit. That process might pay for itself rather quickly, depending on how long you plan to continue renting.

Hardiplank doesn't have a structural rating; it shouldn't be part of the structure. When I see decks done wrong that "don't look all that bad" I try to keep in mind the housewarming party with all of their guests standing on it - a load the deck might have never been subject to yet.

In other words, the equation doesn't add up. It's time to ask yourself why. Either the equation is wrong, or one of your data is wrong. Did you own the building prior to this year? Do you have a basis of comparison from before the changes? Did efficiency improve or did it always behave this way? Have you 'clocked' the gas meter? IOW, watch the dials turn as the unit runs? Is the meter reading realistic?

I could easily see an uninsulated framing cavity where an interior wall meets the exterior wall as a place where more air leaks out of the house, making its way up into the attic.

Looks like an older home. My guess is the ridge venting is newer and the soffits haven't been painted since the ridge vents were installed (my 1973 home originally had only soffit vents). If so it could have been wind blowing in on one side of the house and out on the other. Read up on 'ghosting'.
-
Possible, but unlikely since it was a new appliance in a new house. You can heat the moist clothes all you want, but if you don't remove the moist air the clothes will never get dry.

Interesting. I've seen a dozen or so residential elevators over the years, but they've all been hydraulic. Then again, my market has a plethora of small foundation drill rigs used for installing drilled pier foundations, so getting they hydraulic piston into the ground is easy. Like others, I always punt. So far I've been able to resist the temptation to operate one.

Whoa! An engineer with a pragmatic solution?

I used to get a lot of repeats, but it's moving more toward random numbers. The frequency of spam callers has gotten so bad that I tend to not answer the phone if it's an out-of-state area code. That's a sad testament to how we conduct ourselves as a society. I see no need to be polite to them.

Different compressors?

This is why an Uber-HI-School would be doomed to failure. Given market realities, no one attending could ever recoup the expense of the education by charging a reasonable fee for the elevated level of service.
