Secure the loop back to the house so it can't be snagged.

I see similar things on multi million dollar homes...it's the "dressing room".

It doesn't sound excessive for competent trades people to do what they were doing. I don't know pay scale out there, but around here that would be very reasonable. I'd want at least that much for the work they provided. That said, if I were you, I'd be looking at the contractor that installed it to pay everything. The mistakes they made have the potential to be life threatening; messing up an exhaust is the sort of thing that kills people. If not life safety, then health, as it is well established that long term exposure to low levels of CO can cause a number of health issues. There is no reasonable excuse for getting this wrong. The installer was a screwup. I'd push life and health safety issues in the installers face and tell them I'd be satisfied if they'd get it all taken care of and then go away. Expect their opinion to differ from mine, but you asked, and that's what I'd be looking for. I'd probably back it up with a letter from my attorney to make it clear I wasn't blowing smoke.

That's a nice presentation. Holding the stuff in my hand, I can see it would work great. It's just so ****ing ugly, though.

As timing plays out, yesterday afternoon a roofing contractor came by to give us a pitch for his services. Seems like a good guy. He is also a certified Duradek installer, so he had his samples and handouts for Duradek. Why would anyone go to the work and trouble of building a cool outdoor space and then layer it with stuff that makes it look like a 60's ranch house kitchen? Soulless. Empty. Embarrassingly nasty looking.

The recurring theme in Hardie specs is clearance. That stuff is buried. It's way wrong.

It looks like Kerdi for exterior use. Fuzzy membrane, waterproofing layer directly under tile. Should work like Kerdi. Troba is more an active drainage plane material; big airspace and waterproofing under the drainage plane.

It's the right idea, sort of, but it's also the wrong idea. I really like the house and concept, but why are building everything at the shoreline? Yes, I know, because people like the shore, but..... Forget the politics of climate change for a while, and just think about the ideas of access to shorelines, cultural enjoyment of the commons of the shore, or similarly un-American ideas about how to live, meaning things like shorelines are extremely limited resources and mucking it all up with a couple people's houses is really poor policy.

Yes, I got a couple of those in my history too. Guy's don't get mortar beds right in showers nowadays, so it's unlikely they'll get it done right anywhere. Troba and Troba Plus are both good and we've had them work here @ the 42nd parallel. I wouldn't trust anything with a grout line if there's freezing; we've done loose fit tiles and stone, ungrouted. They hose down and drain just fine. I still wouldn't know what to do until the OP indicated specifically what floor they wanted.

Would you put a permanent flooring system over Duradek?

We've used Troba successfully. It's a great product, but it depends on your flooring. First, determine what your finished floor is going to be. Can't determine much else until you do that.

I rarely don't have the camera in my hand; it's my primary note taking device.

Really. The nice setup is the Fantech inline rated for two inlets....run one duct to the WC and the other to the main bathroom. The whole shebang is up in the attic (or someplace) and you can barely hear it. I've seen single fans work fine; it's more about CFM than two separate fans. Mother Nature takes care of moving moisture around pretty well, and if there's active exhaust, things seem to equal out satisfactorily. Most of the fans I see, you could use 3 or 4 and they'd still not work worth a damn. Also, having one of those nice Lutron switches with the timer buttons is nice.

Very well could be a Lochinvaar jacket then. Tough to say on age. Most will cite 30-35 years, but water quality, flushing maintenance, etc., etc., play a part. When you see the rust stains coming out from under the cabinet like in that one pic, there's draft issues, draft issues often means blockage in the coil, which means the copper is all crapped out and corroded. I usually tell folks to run them 'til they die but don't be surprised when it does.

Was the jacket cast iron or a copper coil?

There's some decent possibilities in there. If I may, I'd suggest moving your horizon lines off center. Basic composition sez have it up or down, but don't split your comp with a horizon. Not surprisingly, the one's I like have the horizon off center.

I think you're looking at the ignition line. There's gotta be a way for the flame to engage down the line. I don't know if there's specific terminology for that area, but it's on every furnace I see.

I'd probably give them an FYI about wanting more ventilation. It seems most builders continue to use those POS little dinks with about 35 cfm, and by the time it's ducted and static is taken into consideration, 8-10 cfm is about what you got. If it was a nice inline Fantech or Panasonic cranking 80cfm+, or even a decent Broan giving 50cfm, it all might be OK. Depends on the cfm discharge.

No, it's the Texas diet; lots of ventilation necessary to keep IAQ below toxic levels.

Yes, I see it all the time. It's compliant AFAIC. If the bathroom is a mega monstrosity with the car wash turbo shower arrangement, I might mention it to the customer and gauge their concern.

We get tubes that small; I see surprisingly small tubes, maybe 1/8" sometimes. It's odd though.

Agreed on composition. Makes or breaks it.

OK, so why is it OK to bond neutrals and grounds in a 2nd building but not subpanels in a single building?

That drawing seems to show bonded ground and neutral in the 2nd subpanel. 3rd panel they're isolated. Why is the 2nd panel bonded?

OK then. I got it. Actually, I always got it. It's the dissertations referencing NEC and acronyms no one I know uses that confuse me. I (more or less) ignore the pre-2008 part; it's dangerous, right? That's why it's no longer allowed, correct?
