Re: Monoflo tees
two standard tees with a ball valve between give you more adjustability, and accomplish the same task

Re: Energy Kinetics System 2000 hard lock out
I finally fixed it. See the schematic drawing.
There is a pressure switch that is a prover to start the burner motor. It has two silicon hoses, one of which goes to the exhaust fan output. There is a hose barb fitting threaded into the exhaust and that hose barb was completely plugged up. It looks like the installer put pipe thread sealant on it and got more in it than on the threads. I believe over time it collected particulate and closed up almost completely. I cleaned it out and it all works now. Thanks to Robert Wickersheim for his help.

Re: Any plumbers good at small bathroom layout?
lack of counter space would be a non-starter with my wife. A shower instead of a tub would be another option.
How creative do you want to get??

Re: Disgusted by today's electricians, Today's rant
I had the certificate framed and it's hanging on the wall.
Disgusted by today's electricians, Today's rant
At one time I had about 12 licenses in different states, electrical, oil burner, gas fitting, sheet metal etc
But unfortunately, now licenses mean you don't know anything. Its becoming a joke. being a licensed electrician used to mean something back in the day. now it means your a hack.
I feel bad for HO calling contractors who not only pay contractors huge $$$ but the work is so shoddy. I have been on the other side for 50 years but I can't blame any HO for doing his own work now.
Long story short, a relative called me who I had re-wired their 1915 house in the early 80s, they have had electricians their doing work over the years since then and have a few issues. One issue is a nasty dirt floor damp crawl space. The other one is very shallow old-time framing that requires the use of shallow electrical boxes with limited space.
So even though I don't really do any "real" work anymore I was curious to take a look. I still have my electrical license and go to the update classes (don't know why).
What I found:
Electrician added new kitchen lights and an outdoor spotlight and wired them to the 20 amp kitchen small appliance branch circuit which has never been ok.
He mounted old work metal boxes by driving sheet rock screws though the back (there's 3/4 wood paneling on the other side of the wall so i am ok with that) but he "grounded" the box by wrapping the wire around the sheetrock screw. NG.
One of the shallow wall receptacle boxes I had installed back in the 80s he extended the circuit coming out of the box. The box is not large enough for the added wire and wire nuts so he hammered the receptacle in to the box crushing the wires which eventually shorted.
He added an arc fault circuit breaker to the panel for an existing circuit that he extended. When I looked inside the panel the neutral pigtail was not connected to the neutral bar. This should have left the circuit with no neutral but yet I had 120 on the breaker and the circuit worked.
Turns out the circuit has the neutral and ground shorted together somewhere. I ran out of time to track that down, but I disconnected that portion of the circuit (with the short) hooked up the AFCI breaker correctly and the breaker and the rest of the circuit is fine.
Because of the shallow boxes and wire fill problems with the smaller boxes you end up with more junction boxes in the crawl space than you would like. Most electricians don't want any part of a crawl space and I don't blame them being in the cobwebs, bent over, the damp dirt floor, rocks, rubble, broken glass tracing wire and a lot of boxes is tough. The difference is they will guess at things, and I won't.
I didn't like it when I rewired it when I was 28
I still didn't like it today at 72 but i spent the afternoon down there.
All the original stuff I did is pretty good. Every problem is where someone hacked things up when adding things like trying to add GFCI receptacles into boxes not large enough
Hope I can get out of bed tomorrow.
My curiosity is now satisfied.
Re: Soldering close to soldered fitting
If it were me, I'd remove the mess encircled in Red by cutting at the Yellow arrow and un-solder at the Orange arrow and rebuild as needed.
Re: I get all the weird ones...
Sounds like they need to hire an engineer to assume the responsibility of the design and the outcome. I would not take on the responsibility of the design.
Re: Best nest thermostat-Experts recommendations to choose
The thermostat is not capable of changing the heating needs of the building. You need X amount of BTUs to heat the place to X temperature when it is cold outside. If you want to save money reduce the heat loss of the building. Weatherstripping, insulation and air sealing usually do the job better than changing thermostats.
In my opinion the best choice is not using a Nest thermostat at all. Save yourself a lot of trouble in the future. If you want WiFi control get a Honeywell or Ecobee
Re: I get all the weird ones...
Tell them straight up, it's not going to work. They need to figure out a different strategy for material handling. Without knowing the process, I can't really offer suggestions. If they insist on trying to heat a 5k sf building with a 22x18 door hanging wide open, walk away. Working for idiots is financially risky and you won't get any satisfaction.
