To All, you do not need documents to know that an 8 percent reduction will cause AC units and other equipment to to fail. Ask the people in my community. Just think about it. If you have a normal reduction in voltage that occurs during the summer, lets say just 4 volts, then you add a reduction of 8 percent, which is about 9 volts. What do you have?

Jamie, I did not say it was to spike the customer. I said it was not for you the customer. The main goal of the utilities is to protect their equipment. As for the situation in Spain, They and any person with a good understanding of power grids knows what happened. They just did not admit that they did not know what they were doing. Your power network cannot rely on a high percentage solar and or wind energy plants mixed in with coal, diesel or hydro turbines. If they do when there is a sudden drop of power because of cloud cover, wind velocity or load change, you will have chain reaction disconnects. Why, Because gas, oil powered and hydro powered systems have centrally located large turbines. Solar and wind systems do not. The massive size of the turbines spinning will have inertia and temporarily compensate for any sudden changes in the grid so they can be corrected by automated systems. Politics in Spain [the push for solar and wind power] led to their situation. How can you not know what happed days later, with an automated and fully monitored system?. Getting back on the subject, those of you who have local law 97 requirements should do all you can to optimize your steam systems and think twice before playing games with these heat pump alternatives. Heat pumps have compressors too and the reliability and cost of these systems must be determined. The price of electricity is also an issue. Coop managers and Directors: Do your home work
Re: Any idea for this radiator hookup?
I think what @mattmia2 means is use a "standard union" female pipe X female pipe on the existing pipe coming up through the floor then use a nipple and elbow to get the correct height and a nipple into the radiator.
You can also get copper unions that are sweat on 1 end and either male pipe thread or female pipe thread on the other.
Depending on the room you have you could use a copper sweat x female union on the pipe coming out of the floor or use a copper sweat x male union in the radiator.

Re: Frost free sillcock rated for continuous use
the screw on vacuum breakers are really the same as the built in ones. either one will spray some water if the wrong pressure differential happens and either can fail to close after that either from debris or a degraded seal.

Re: Frost free sillcock rated for continuous use
The 32 is really just a very expensive valve, escutcheon, and union.

Re: Mystery domestic water line
Hi, I saw this on Ebay "Metrotech Model-420 Pipe And Cable Locator Vintage Transmitter/Receiver". It's not expensive. A locator that can be attached to the pipe inside will let you trace the line wherever it goes.

Re: What happened to Rems Tools(USA)
The REMS came with a pair of pliers with a couple prongs to dimple the tube. I lost mine.
The T-Drill tool cuts the curve profile and puts the dimples in. When you look down the trunk you do not see ant branches protruding in. You do with the REMS tool, however.
