Detailed notarized experience letters from past employers on letterhead are not acceptable to municipality or state? You got that in writing?

The hilo in the original thread only wanted somebody to rub its' belly. Either that or it died.

Hey, you ever priced out a bunch of black couplings and nipples, and not to mention the amount of teflon tape that would take? We don't own no stinkin pipe threader either, just a waste of money....

Cutting that paddle down to fit was not his job. Or, the pipe has so much crap in it that it actually used to fit. Been there.

If that job has a problem with repeat broken paddles, other than by...

RSES sells the Dewalt HVAC certification study guide that is Q & A. McGraw-Hill has a HVAC licensing study guide that is Q & A. These questions are similar to the city or state license exam...

Overfeeding of water treatment. Possibly incompatable treatments mixed. Biocide may foam some, but overfeeding of one biocide. Hopefully you have not been mixing two biocides together at the same...

Sounds like an engineer who thinks he has all the answers . What was his alternative material? Was he looking for the red and blue PEX like in the house? Copper is what is offered and has a lot of...

Regarding the flare gauge, check with a Daiken supplier. I have one, but no part number on it, at least in english. http://www.behler-young.com/tech-tips/what-do-we-know-about-flare-fittings ...

That's either a romex connector or mc cable connector on the furnace, not compatable with emt. Should have painted it so it wasn't so obvious. Switch, we don't need no stinkin switch. It may have...

Is that copper going to that fernco connected to the black pvc in pic.2?

Wait till Barney Fife catches up with them and slaps the EPA fine on em for venting.

Hopefully it's the Hydrobalance. But maybe it's copper sulfate, the stuff they put in decorative ponds.

Use a sheave gauge to judge wear on both sheaves. With distance in photo it is hard to tell, but it looks like belts are riding too low in sheave. So that's either wear or wrong belts. Are the...

The control board was called ICECON, and from what little I recall the software was of the same name, but it came on an unmarked CD. You have to contact ICE for it. These low temp rise units were...

Borrowing a Three Stooges plumbing line, "no wonder it don't work, it's all clogged up with wires!"

Your inquiry was about mandating that the northern states have only 90% furnaces on new/replacement installations starting May 1 this year, while southern states have a minimum of 80% furnaces. That...

RX-11 is non-flammable but paint thinner is flammable. RX-11 is also approved for the use, while I would guess paint thinner is not, nor would it probably be compatable with system components. ...

You guys got it all wrong. That's either a rescue transformer like a dingy towed behind a boat, so in case the blue smoke comes out of the main transformer, it can take over in an emergency, or it's...

If it had been a metal wall, it may have been rotted through by now. As for the wall, maybe it's bad mortar or stucco.

Sorry,...

My experience with ICE units is similar. We had about a dozen non-Icecon controlled units which worked great, and they are high temp. rise units. The four newer units controlled by Icecon boards...

Oh goody, railing as required by code, but don't think working on it from that side of the railing is approved. Almost makes you wonder which was there first, the rail or the RTU.

Couldn't find the article I was thinking of when I first posted. Go to page 7 for "One Engineer's Opinion.
