I need to install a water heater in a basement

According to IBC codes, pressure-relief valve piping must exit the structure but the basement floor is 8' below ground and the piping cannot go uphill. So what do you do to drain water should it discharge?

New construction insulation options

We're having a new home built in southern NH, roughly 2100 sf. with southern exposure to the rear of the home. The builder is including ZIP System R-Sheathing R6.6 with 6" R21 fiber glass batts in the standard price. I've been quoted about $5k to add 2" of closed cell foam in the wall cavities on the back side of the sheathing (keeping 4" of fiber glass in the remaining space). They are also putting R49 in the ceilings, R30 in the slopes (our plan has a few slopes on the 2nd story). They build to better than energy star standards, taping seams, caulking etc.

Can someone please provide feedback on floor mounted air ducts?

We are building a raised home using shipping containers and want to put the air ducts in the concrete floor since there will be little to no room between the roof & ceiling. I'm wondering if this is recommended or if I should re-design the roof to fit the HVAC system under it instead of under the house.

How do you install rigid insulation to a foundation wall?

EcoSeal in Maine?

Does anyone know where I can source a couple pails of EcoSeal sprayable caulk, in Maine?

I was fully intending to seal our house (new construction) with sprayable caulk, but I can't find a source anywhere . I've tried contacting Knauf, area reps, etc. but that does not seem to be getting me anywhere.

Any tips or suggestions, or better yet, somewhere I can place an order??

I have 4,300 sf of Chicago brick that needs to be power washed and sealed

Which is better: oil-based sealers or water-based? And can I use water-based over oil-based?

I need more information on the care and maintenance of Chicago brick in a climate like Ft. Myers, Florida. The previous owner also used polymeric sand to fill the joints. Is this best or regular sand?

Thank you.

Using ZIP R Sheathing

I'm using ZIP R sheathing on the exterior walls and wonder if it is a good option for the roof. I was considering exterior insulation, but it is a more complex solution than my framer may be willing to tackle. I'll probably go with closed cell against the sheathing and then another type of insulation to achieve the required R value. If I used this strategy, should I have the plan ZIP panels for the roof sheathing?

And yes, I'm aware of the growing controversy concerning spray foam. I would prefer not to use it, but I have to keep this project moving along.

Attaching extra fiberglass to 2x4 attic wall?

Simple question How do I support extra batts on an attic knee wall?
My attic has knee walls next to a bedroom, and I want to add 6" fiberglass insulation on top of 4" existing fiberglass between the 2x4 studs. On a hot day the interior wall temperature was 110 degrees!
Is stapling the facing to the studs adequate? Do the batts need wire supports, and would I be able to bend 24" OC wires to bow out to fit between 16" OC studs? similar to Lowe's insulation supports?
Other DIY support methods?
Would you put rigid insulation on the back of the hatches leading into the crawlspaces?

Venting between kneewall attic and peak attic

Hi everyone -

First time here. I have a 1956 home that I am gradually upgrading various parts of.

I need advice/help with knee wall to peak attic ventilation.

I am in the process of deciding whether to seal/insulate the kneewall attics for storage/year-round temperature regulation. (Previous owners had a weird mixture of batts and poly, which I aim to rectify with polyiso, etc.)
