  1. 5 individual wires and a few meters of heat shrink or pull in conduit/poly tube or place in panduit on wall ? if you have that much current, heat might be an issue over time, so i would consider the insulation temperature rating for full conduit rather than air.
  2. Then a Square U bolt bracket and flat plate with a bulge for tensioning should work. Otherwise, the square reinforced concrete poles i have seen around the world had sleeves where through bolts were required. here is an example- note the angles of the clamps
  3. Look at the far right picture . Pair of stainless band clamps anchoring. If the concrete pole has any taper, that should work if the manufacturer gives it as an option for attaching.
  4. What is running on the pc at the time and what program is being displayed ? if it was one, i would look at video cable or other loose connections. do they all do it at the same time or is it more random ? what updates happened just before this started ?
  5. Another issue to consider is getting the coating to bond to the block substrate. It certainly has to be cleaned of dirt and any friable or spalling surface material and salts and allowed to dry. Usually takes a pressure wash and/or vigorous wire brushing which sounds difficult in this case.
  6. Is the base wood board, Medium Density Fiberboard, or plywood ? Are the legs on a steel plate that these screws are anchoring to the base ? you really want a drill press to screw in the nut insert in the picture above using the double nutted bolt or all thread method. Even using a hand power drill will work, but is easy to get off line and tilt the nut insert or tear out the MDF. Just go very slow on rotation while pressing firmly into the MDF. I’ve seen many using the screws you were provided. They work as long as the cabinet does not get shifted around much as they will tear out after a while. the insert in your picture has no pull out resistance to speak of and really isn’t suitable. The threaded nut inserts do a much better job of it.
  7. Go back to the doc. Get checked out. Also ask about mycoplasm ( walking pneumonia - takes 5-6 weeks of antibiotics ) or fungal infection.
  8. And you have to drain the system too …… i would find a “recommended” plumber to figure it out. is this a standalone condo or part of a larger building ?
  9. Is access only from the sides or do you have full access from above ?
  10. There may be compression union fittings than can join the two materials , but i would avoid if possible as you should only need to run from one or the other type.
  11. One tip - don’t use fast cure pvc cement if possible if this is your first attempt. Make sure the surfaces stay dry inside and out until the glue has fully cured. Otherwise, you should use glue designed for wet applications. It has a higher THF concentration and you will have to work faster. Don’t put water pressure on it until fully cured.
  12. If you only need cold water, why do you want to connect the hot and cold supply lines together ? You only need to cut in a repair branch fitting on the cold supply and run a pvc line over to the washer location. Make sure you cut the line square leaving a gap equal to the branch line id, clean off the burr, clean and prime the line and fitting, then apply the pvc cement to both the fitting and the pipe. You need to give it a quarter turn twist and line up in the correct orientation. If you can’t get a repair fitting, you will need to be able to move the pipe to one side or both the full length of the fitting while gluing. If that is not possible, cut a larger section out and use the branch fitting, a short piece of pvc pipe and a repair coupling. Glue the repair coupling in place last. PVC glue joints do not like to be be under stress. The “glue” will creep and the glue joint can fail. i assume you will be using a hose to connect to the washer cold supply valve ? What about the plans for the drain line for the washer ? Most codes require an air break to prevent siphoning from the drain line back into the washer.
  13. There are many reasons the weld can fail, but done correctly, it becomes the “same” as the surrounding metal. One issue can be stresses created in the metal near the weld if it is not heat soaked to allow the crystals to redistribute. Contamination of the weld, or using the wrong composition sticks for the metal or poor technique are others.
  14. Next versions are targeting areas of the virus that do not change as rapidly as the spike and are common across all of the variants. This should allow for an annual approach or longer. Researchers are looking at a similar approach for the influenza virus family.
