New Article on CO
Hi, Allison Bailes has just published an interesting article on CO and the ways we can be poisoned by it, even in an all electric house. 🙀 Here's the link:

Re: System 2000 oil fired boiler
Good sleuthing, @skyline137 !
A good clue is that the zone output light for zone 5 is off, so it was not open from the control, but mechanically stuck as you determined.
Best,

Re: Skimming Sump Setup
I would do a short nipple thru the jacket, and ball valve, then have the extension nipple and drop El removeable(loose ish), so you don't have much leverage hanging out there, a plug in the valve when not in use,

Re: 3,500 PPM CO
We just finished the service. We clocked the boiler at 250K, so no problem there. The burner and HX were pristine and on first glance, the venturi was in good shape. But then I noticed that the adjustment screw was retracted all the way, so the problem seems that the burner was getting too much gas.
I could have tried dialing down the venturi, but I had a new one and I didn't want to di*k around with a device that may have something else wrong with it.
The boiler is working fine now. CO numbers come in at 60-70 ppm on high fire.
Re: Appliances
A switched receptacle under the sink for the disposal is another method I have seen in new homes. We put cords on disposals when I was doing new construction plumbing. Johnstone Supply dold disposal cord kits with nuts snd. Ird vonnectir in the bag.
A hot receptacle under the kitchen sink is handy for a HW dispenser also
I have also seen dishwashers corded and plugged into receptacles
I’d add a receptacle behind the toilet if I were an electrician these days, bidet seats are becoming more popular.

Appliances
Hooked up a dishwasher for my nephew. Maytag label on the front door. Paperwork says Whirlpool which is also Kitchin Aid.
The inside is a dead ringer for the Kitchen Aid I installed in our condo 3 years ago. Just different controls on the door.
While I was laying on my back under the kitchen sink hooking up the DW drain I noticed the cord on the Insinkerator 750 PRO disposal (about 4 years old) was falling out of the disposal. Well, guess I might as well fix that too.
Guess I have been away too long as all the disposals I ever wired had a little junction box with 3 wires in (or 2 with a ground screw) it and a knockout and you either used a cord or hardwired it and connected it with wire nuts.
No more.
This thing has a rinky dink plastic connector that plugs on to the motor terminals and then the field wires plug into the other side of the connector…..like backstabbing a receptacle. How do you plug stranded wire into a backstabbed receptacle type connector ???…..you don't.
I knew something wasn't right.
When I got home I looked it up on line. The connector that come with the disposal is for hardwired only so you can plug solid NM or AC cable into it.
If you want to use a cord you have to go to HD etc and for $17 you buy the "Insinkerator Eazy Connect factory cord" which come with a plastic connector on the end to fit the motor connections.
The guy that originally installed it just tried to push the stranded wire into the connector with the backstab type spring clips. Didn't work.
Insinkerator say this was done to "help" diy homeowners wire their disposals. ……………..Not if they can't read the instructions. And Neither did the plumber who got paid to install it.
Re: Dope & tape?
Still far, far better than sitting watching reality tv….
At least that's my honest opinion.

Re: Glycol Additives for new Ground Loop commissioning
Dowfrost abd Dowfrost HD are both PG non toxic glycols
Dowtherm is an EG. While slightly more toxic, EG does break down easier when spilled. Just don’t drink it
GEO fluids are often ethanol or methanol, easier to pump compared to glycol

Re: New Article on CO
there are basically no fumes coming out of my oven while normally cooking or while in self clean mode. i put a sheetpan in the oven that had some grease on it and turned it on at somewhere around 475 or 500 because i was going to put something on it to make the crust brown. that grease smoked a lot but I didn't see or smell the smoke in the kitchen until i opened the door. I had to turn on the hood over the cooktop and open the door in a couple stages to get the smoke out without setting off the smoke detector. If I don't see or smell smoke from inside the oven cavity I just don't see where there is a lot of air moving in and out of the cavity during normal cooking or self cleaning. It also seems like if it weren't fairly well sealed that it would lose a lot of heat from the convection fan stirring things up.
I wonder if that big lock lever on an older ge moves a shutter to close off the vent at the top of the oven cavity.

Re: New Yorker Boiler Coexisting with Hot Water Heater
Hi, I'm wondering if the tempering or mixing valve (at the boiler) is working. You should be able to use that to prevent "too hot" water from feeding the water heater.
