    Plumbing - NPT vs straight thread

    They just thread on and the gasket seals them. I'm not crazy about them but they work and I have used them many times in the past.

    You sure that came from rock auto? That seems really odd to me.

    Any recent VOA of Providence 5w40 HDEO?

    I'd be curious to see what it looks like. I figure its run of mill but who knows.

    Made it to APRIL. Again!

    I converted to dual fuel about 5 years ago. Have a forced air oil furnace and added a heat pump because I had no AC. It has cut my oil consumption down so much that it has easily payed for itself. I have it set to lock the heat pump out below 20 and run oil. Above 20 it runs the heat pump. We...

    Weird Heat Pump Issues- Article

    My only other thoughts are its the contactor chattering or the reversing valve chattering but neither or those are generally that loud. Other than the fan motor and the compressor those are the only moving parts. Both the reversing valve and contactor run on 24 volt power so even with the...

    Weird Heat Pump Issues- Article

    I'll be curious to see what you find out because Bryant doesn't use a thermostatic expansion valve in their outdoor units. They use a fixed orifice called a piston.

    Weird Heat Pump Issues- Article

    If the system is sitting with no power on the pressures have equalized between the high side and low side so no refrigerant is flowing. Even temperature changes throughout the day wouldn't cause enough flow to make any noise. Ive been doing hvac for close to 15 years now and have never heard a...

    Weird Heat Pump Issues- Article

    If the unit isn't running it shouldn't be making any noise at all. No refrigerant is flowing. The only time the check valve in the TXV comes into play is when the unit is running an switching between heat and cool mode or when going through a defrost cycle. If your running the oil heat and...

    Mercedes driveline rumble

    Drop the drive shaft and check how the u joints move. They should turn freely without binding. If you turn them from side to side and they bind up at all they need replaced. Just because they dont have any play in them doesn't mean they are good and you won't be able to tell if they are binding...

    Morals and working with the public

    Business is in business to make money. If you gave them the part for what you paid for it you wouldn't be in business very long. Obviously people can shop around and get better deals but some people have no interest in going someplace different and some have no interest in tracking something...

    Coyote Encounter

    You did the right thing. There have been quite a few people attacked by coyotes. They are dangerous and when they get into a pack they will attack something much larger than them.

    Cold Climate Heat Pumps

    Surprised that thing isn't on snow legs. American standard/ Trane uses demand defrost activated by a coil temperature sensor on the coil. Some other manufacturers use timed defrost which is not as good. My bosch heat pump is demand defrost and on certain days the coil will be completely frost...

    Home inspector flagged multiple neutrals on single lug in breaker panel

    Check out "N Bundy Electrical" on youtube sometime if you are curious about how they wire houses across the pond. Way different from what we have here.

    A lot of the big companies have been doing this for awhile around here.

    Home inspector flagged multiple neutrals on single lug in breaker panel

    No because a GFCI outlet only cares about whats on the load side of it.

    Have an idea for transmission pans

    Would be nice to just have a spin on filter with the coarse style media they use for the regular trans filters that could be accessed without dropping the pan. Even if it wasn't a spin on and used a cartridge style that was external that would be nice.
