In the future, if you need a Goodman part quick to get your heat going, Ferguson HVAC in Raleigh will normally have it in stock. They are a Goodman distributor and not a repair company.

If you use the pressure rating and wall thickness of M copper to calculate its stress at the rated pressure, and then use that stress and the wall thickness of copper fin tube, you'll get a max pressure in the range of 400 psi for the fin tube. This is based on values for 3/4" M copper and 3/4"...

You're correct. I only looked at the pumping characteristics which are similar to a centrifugal pump in that the design of the impeller limits the maximum head. I'd call it a semi positive displacement as opposed to a true positive displacement such as a gerotor pump or piston pump which...

Use a centrifugal pump rather than a positive displacement one and you'd have no need for any bypass or recirculating loop. For example, this 12V pump from HF https://www.harborfreight.com/12v-dc-transfer-pump-290-gph-63324.html at zero flow will produce 17 psi and it would just sit there and...

The male end of a fitting isn't a flare nut. And, in working on this sort of stuff for about 55 years, I've never seen or heard of a sweat flare nut.

The one you linked has 90+ percent 4 and 5 star reviews based on 500+ reviews. That's about as good as you'll do since there's always a certain percentage of people who buy tools and are so dumb that they couldn't figure out how to use a soup spoon, but they still blame the tool for their own...

Using the size of the marker light in the pic to judge the size of the tubing, those outside corners look way too sharp for 3/8 wall tubing. Standard outside radius is 2X wall thickness, or 3/4" for 3/8 wall.

I've got a Komatsu PC-05 from the 90's. About the same size and weight as these Chinese machines. One of the most handy features of mini hoes is the ability to swing the boom to the side so you can dig alongside a foundation or other obstruction and still have the ability to swing the entire...

5 inch pipe should be fine as a substitute for 5" square tube as a column in this application, but unless you have some means of verifying the soundness of the pipe, I wouldn't recommend using some unknown piece of pipe that's been hacked out with a torch as a part of some demolition as the one...

If you intend to spray, keep in mind that adding hardener to any paint other than epoxy creates a mix with all the hazards of full blown urethane paint. The hardeners in all these products contain isocyanates, so, to safely spray them you need full protective gear and preferably a fresh air...

A 12K Pioneer 19 SEER kit is $860. 12K 22 SEER kit is $1100. Pioneer has the same line cover sets as Mr Cool for roughly half the price. I have 2 Pioneers, both self installed and going on 3 yrs old with zero problems. One 9K and one 18K. Couldn't be more satisfied. pioneerminisplit.com

Based on a few articles I've read, the common practice for mini split installation in Asia is to do something {quick evacuation, blow some refrigerant thru the lines, etc} to remove the bulk of the air from the system, then hook up the lines and let 'er rip. The helter skelter variation of...

You have to look at the definition of high and low pressure refrigerants as defined by federal regulation 40 CFR 82.152. A low pressure refrigerant is one that has a saturation pressure less than 45 psia (30 psig) at 104*F. In simple terms, this means if you put a liquid refrigerant in a...

Here's some information on required certifications published by the EPA. https://www.epa.gov/section608/epas-refrigerant-management-program-questions-and-answers-section-608-certified If you scroll down thru it, there's some information regarding mini splits. One notable statement is that...

A 608 type 1 certification allows you to work on the refrigeration system of small appliances such as refrigerators, window units, and other appliances with 5# or less of refrigerant. The restriction on type of refrigerant applicable to such appliances isn't really restrictive at all. Over the...

I've got one of these. Bought it for a hundred bucks from a guy who didn't realize it was 3 phase when he bought it at a machine shop auction. Takes a bit to learn how to use it, but once you do, it does a real nice job. It uses a porous wheel where coolant is fed thru the spindle and out...

That would be General Tools and not US General. The General model 825 drill grinding fixture is still manufactured and is available for about $25. I bought one in the early 70's to modify some drills to a 90 degree point angle to work as a countersink for about a bazillion flathead screws for...

Unless there's something out of the norm with warranties on mini splits as compared to other contractor installed hvac systems, the labor warranty will be for only one year regardless of the length of the parts warranty. That's pretty much standard across the HVAC business. The contractor is...

He doesn't need a taper pipe tap. He needs a straight thread tap. 1/8-27 NPS. The plug would use an O-ring for sealing. When he gets the one out that's in there now he'll likely find some hammer fisted ***** in the past has used loctite or some similar compound to seal rather than using an...
