A cup of coffee.

HI schools here include field mentoring in the cost of tuition.

The Code Council offers some on-line courses. Contact them about when the ICC University starts. I think that it was supposed to launch January.

I read that T&G manufacturing equipment was in use in mid 1880s.

Yes. CPVC is often used for DWV and floor drains in industrial buildings.

Heat from a chemical reaction. Likely sulfuric acid drain cleaner.

For years it has been reported that poly pipe and plastic fittings are a disaster waiting to happen. Oxidants in public water causes poly to wear away from contact with plastic fittings.

Poly pipe reacts poorly with the oxidants in tap water and becomes fragile. The trouble is from within; deterioration of the pipe takes place from within making it unforeseeable. There are no signs of impending leaking, and when it goes - it goes!

Last but not least, insurance companies purportedly cancel or refuse policies for houses with poly pipe problems.

I have a house where the plasic pex fittings are poping off the 90s and T's. Three so far. You hear a load pop then a flood. Has anybody else had this problem?

Got city water? Water-powered backup sump pumps are available from 700 to 1800 gph if you have 60 psi water pressure.

I initially misread the title of this topic. I thought it read "My first porno video"

I was a little disappointed.

Apply a spit-coat of dewaxed shellac before any dark stain.

I neither have a humidifier, nor a water softener.

The white residue can be made up of many things, but your issue is likely due to byproducts of combustion venting into your home and not outside.

It looks like the same format as Kenmore which is a letter followed by 7 or 8 digits. the 2 digits after the letter are the year. 00 = 2000

You can confirm with the date stamped inside the TP relief valve handle.

Perhaps some more pertinent info may help: The Propane Fueled Fireplace is a Direct Vent Fireplace. Other: About 3 years ago we installed a Water Softener & we take this water & put it into a portable humidifier that runs 24/7 during the winter. I am now wondering if what we are experiencing may be related to Softened Water Mist Particles evaporating & settling as the White Powder (perhaps combined with Dog Dander from our two Golden Retrievers) - I do NOT remember experiencing this issue prior to using Softened Water in the Portable Humidifier - ANY thoughts/Comments (or) Experiences along these lines ? PS. All of your comments & replies are very much appreciated (Great Website)

It is quite likely the humidifier. I guess it could be salt from the softener, but is likely some other minerals in your water. Thoroughly clean the humidifier and and go get some distilled water. Let us know if this clears it up.

He didn't "take control". It was already dissolved, gone, dead. Nick just got some more letters from the alphabet.

My dad (was a photographer) has been going to B&H Photo in Manhattan since the early 70s. Best customer service and nothing they don't have in stock.

I buy everything from them online. If I can find it anywhere else for less, they'll match it (they've slit open a box to give me an "open box" discount).

What are VF logs?

It reminds me of a farmhouse I inspected........ after a plane crashed into it.

The cracks are only in the surface glazing.

Google crazing.

Almost full schedule, mostly commercial buildings.

Now that DST has set in, I'm even more limited.

Positive vent pressure appliances must vent into pipe listed for positive vent pressure, which is UL 1738 or PMI, which is where the illegal use of PVC comes from. PVC has never been approved for venting in the US by UL nor by IAPMO nor any mfrs. I'm aware of. Still allowed though by IRC for now.

Is it okay to connect PVC to a B vent?

IRC sez vent material "as specified by the manufacturer". All manufacturer's of cat IV furnaces will specifically exclude B-vent.

Just did a building where 10 space heating units were just replaced with cat IV furnaces. I'm guessing the installer didn't want to change the B-vents through the roof.

That's right! His house was the original record at 2600 something.

This explanation is more on my level of comprehension:
