    Freeze protection for hot/cold outdoor hydrant

    I wouldnt use that valve in a single digit climate, and not even in low teens climate. Proper exterior hose bibs look like this...

    Cutting threads on grade 5 stock

    The problem with cable is that it is way too stretchy vs the rest of the structure. Even if you preload the cable, it will stretch under a high load, allowing connections in the wood framing to be damaged. Stick with steel strapping or rod.

    Finding a roughed in Toilet drain under slab.

    An option that hasnt been mentioned yet: Use a test plug with extension hose to plug the sewer line at the first cleanout. Use a rubber coupling to install a 5-10 ft standpipe. Fill with water, wait a few hours, and then look for a damp spot in the concrete floor. Concrete is very porous and...

    MWBC solutions

    IMHO, having AFCIs just increases the chance that an outlet wont work reliably. So you need to make more use of extension cords, and extension cords do not enhance safety.

    Roll up door side seal

    If you dont find something local, try these guys: https://www.garagedoorweatherseal.com/product-category/brush-seals/. I went with their blade seals on my overhead sectional and those have worked very well. The rails arent inclined on rollup doors so the door will drag on the seals for the...

    Steel Sources

    If there is a big steel fabricator nearby, ask them where they sell their leftovers. Otherwise, search for metals recyclers or scrap metal haulers.

    Steel Sources

    The most expensive place to buy is an online metals place. Second most expensive place to buy is a welding shop where they will cut a piece to length for you but will charge 4x-5x the price per lb that the steel yard will charge for a full 20 ft stick. If you have a large enough local metals...

    Any reason why I shouldn't use PVC jacket MC cable for barn power?

    A fair question. I have had to do this three times in my life but in each case this was only necessary because the original wire install had been botched. Worst install involved nm-b cable in the conduit that had been spliced with electrical tape.

    Cut and cap live PVC

    Just use a compression fitting intended for this purpose. You will get wet but not nearly as wet as if you were cutting into a 6" pressure line. https://www.plumbingsupply.com/pdf/spears-griploc-coupling-install-instructions.pdf

    Really Strong Wall Mount?

    If you don’t mind a slightly industrial look, this is what unistrut is made for. Cut two pieces to be bolted horizontally across two studs at the top and bottom of your bar. Then use strut pipe mounts for the exercise bar. If the bar has its own mount hardware, secure that to the strut using...

    Shop build (helping a friend) - load reactions at the columns

    If the metal building manufacturer cant provide proper drawings and calculated column reactions, how do you know that any aspect of the building is correct? You need to find a competent building manufacturer who can provide column reactions and calcs to show that the overall structure will meet...

    Spalling Garage Concrete Repair

    4. Maybe whoever placed the slab saved some time by using calcium chloride to accelerate the set.

    I cut open my air compressor tank. Take a look..

    The youtube video is why I am convinced that vertical compressed air tanks are a bit safer than horizontal. Horizontal tanks, unless significantly inclined, allow water to accumulate and cause corrosion in a line that can fail like a zipper. The dished bottom of a vertical tank has corrosion...

    Detached Garage Voltage Has Dropped to 103v

    I had similar symptoms at a well house. Was fed by UF cable in conduit but there was an electrical tape splice inside the conduit that had corroded badly. If your conduit isn’t full of mud should be easy to pull new cable.

    code inspection question for solar roof conduit steel building

    Rainwater on the conduit will follow it around the bend due to surface tension. So ordinarily you would want it to either enter the building through a watertight gland or you would bend a slight drip loop into the conduit. But you are in a desert so maybe inspector would just accept some caulk...

    Delamination on new pour

    You should clear any repair detail with the engineer who designed the structure and with the permitting agency. No idea where you are but particularly in earthquake country you don’t want to make ad hoc changes to a design. The rebar might have been run from footings to slab out of convenience...

    Rationalizing the purchase of a backhoe

    I have a backhoe attachment for my bobcat that has definitely earned its keep. But for big or complex jobs I typically rent a mini ex. The 360 degree boom rotation and ability to dig alongside a wall make a backhoe seem really primitive. If I ever buy another machine it will be a mini ex.

    Any experience with "Synthetic Macrofiber" in concrete slab? Euclid Tuf-Strand

    If you aren’t prepared to put in at least ACI minimum steel (and #4 at 2’ oc is less than minimum), the rebar is just a waste of time and money IMHO. Fiber will help to control how many cracks you have to look at.

    Building on a Slope

    It is hard to answer without seeing the site but here are a few considerations to discuss with the contractor you get on site: You dont want to build on top of organic material so you need to remove that. Could be anywhere from zero to 6" or more of organic material depending on vegetation at...

    Best electrical tape?

    Code specifies aspects of the finished product. At least in my experience, osha is looking at hazards that may be present in the workplace. Even a damaged extension cord that is patched with electrical tape can earn you a citation.
