I laid down my pavers beautifully, gave them some time to settle, and then swept the polymeric sand into the joints. I was very careful to get as much of the sand off the actual pavers as possible, but inevitably there was still a light dusty residue that couldn't be swept off. I misted the pavers as advised (4 times in 20 min increments), and when everything dried up, my pavers looked terrible! There is an obvious residue left on the pavers. We tried scrubbing with a wire brush, but that changed the texture of the pavers. I am hearing that vinegar and a regluar (less abrasive) brush might work? How about a power washer? Has anyone else gone through this beforeif so, please help!
When you take off in a space shuttle, you have to be going insanely fast. And that speed generates a lot of heat. Have you ever seen a movie of something falling from really high and catching on fire? Anyway, the thermal blanket is a protective layer so that the people in the shuttle don't heat up and explode or something equally dreadful. What the article is saying is that a piece of the thermal blanket came loose, but luckily it wasn't in a really critical place (as mentioned above, the most vulnerable places to heat damage are the wings and nosecap). Hope I helped!
Isolate which detector may be doing it. Did you buy the same brand and simply plug it into the same connector without touching the wires? There may be a loose connection at the splice or at the interface plug to the detector. Each detector Should have 4 wires in the box (and 4 leaving to the next one) Ground, white black and red. The grounds get tied up together. The black is hot, white neutral and the red should carry the interconnect to each one. Check the wire and the wire nuts with the power off. Hold the wire nut, and tug at each wire to make sure none are loose. Since you have the same problem with brand new units it's likely a loose connection at the wire nut or the interface plug.
