comment At what height should CO detectors be installed?
Found this: NFPA 720 "9.4.1.2 Each alarm or detector shall be located on the wall, ceiling, or other location as specified in the manufacturer's published instructions that accompany the unit. and "9.7.1.1 All carbon monoxide alarms and detectors shall be installed in accordance with the manufacturer's published instructions. and "A.9.4.1.2 The location for effective performance is not generally dependent on mounting height. The density of carbon monoxide is similar to that of air at room temperature, and carbon monoxide generally mixes readily with air."

International Residential Code also points to NFPA 720, and the manufacturers installation instructions.

comment Electrical Circuits in a Workshop
If you're not verifying power is off before sticking your hands in the box, then you shouldn't be sticking your hands in the box at all. I'm simply pointing out that it's incorrect to say "You cannot have multiple circuits in one box unless it's on a two pole breaker", because it's simply not true.

comment GFCI circuit is contaminated
Sounds like you've got a bad neutral. Check all the neutral connections in the circuit, including in the panel. And test continuity of the neutral from that location, back to the panel.

There's no problem with having multiple circuits in a box. The only time a simultaneous disconnect is required, is if the circuits feed a device on the same yoke (split receptacles for example).

comment Should I move this support post in my basement?
If you get a permit for this job, the inspector should only be inspecting aspects of this job. Also note that bedrooms in basements require an emergency escape route, other than the stairs leading out of the basement. Which means you're going to need an egress window or door leading to the outside from the bedroom. Well, that is to say. If you were doing permitted work, you'd need the escape route. If you don't include the escape route, you can't list the bedroom as a bedroom if you ever sell the house.

comment Quarter turn connection for plastic tubes — Design idea request
Look at common PVC fittings. You'll notice that where the pipes mate, the diameter of the pipe is increased to allow one pipe to fit into the other. Without at least this level of diameter increase, you'll likely never find a way to mate the pipes without using an additional fitting. The pipes have to slide past each other in some way, but reducing the wall thickness to allow this would likely weaken the pipe too much.

comment A/C Air Handler Leaking Water Everywhere
If you're using one of those things, you could just leave open a cap on the side away from the air handler.

comment A/C Air Handler Leaking Water Everywhere
@Mazura I'm not saying this is the cause of the leak, just pointing out that it could be contributing to the problem.

comment A/C Air Handler Leaking Water Everywhere
@Mazura From a random air handler installation manual "A drain trap in a draw-through application prevents air from being drawn back through the drain line during fan operation thus preventing condensate from draining".

comment A/C Air Handler Leaking Water Everywhere
@Mazura A positive pressure system would push air (and water) out of the drain, which is why furnaces (positive pressure) don't require traps.

comment A/C Air Handler Leaking Water Everywhere
If air is coming in through the drain, the water is likely not draining until the unit shuts down. If it runs long enough, the condensate could theoretically overflow the pan. When the unit is running, put your hand (or a piece of toilet paper) over the vent. If you feel suction (or the TP is pushed in), you're going to want to consider replumbing the drain. NOTE: If you're using toilet paper to test, make sure you keep a firm grasp on it. You don't want it to be pushed into the pipe.

comment A/C Air Handler Leaking Water Everywhere
The tee is left open as a vent, it just happens to make a handy clean out. Just as you have to vent the traps in your plumbing system, you have to vent this trap as well.

comment A/C Air Handler Leaking Water Everywhere
If this is an air handler (negative pressure), the drain is installed wrong. The vent (open tee), should be after the trap. As it is now, air can be pushed in through the vent (open tee) and prevent water from draining. This could be part of your problem. The purpose of the trap, is to prevent air from entering through the drain. This setup does not accomplish this.

comment Spa pump wont run when in spa
I agree with Paulster. It sounds like the motor is good, but the pump is stuck. The motor can't spin the pump, which causes it to draw a very high current and trip the breaker. Usually there's fuses in place, to protect the motor from this type of situation. The idea is that the fuse will blow before the motor burns up.
