Used to distinguish individual users by means of designation of a randomly generated number as client identifier, which allows calculation of visits and sessions. I had been wrapping rubber roofing with hose clamps on the pipes where i could get to them but some of this ran through finished ceilings and i was starting to see spots there. I changed the piping routes and had the whole thing fixed in about 3 hours with the press tool. I was convinced. If you, as the hirer, refuel any equipment while it is in your possession, it must be with WHITE DIESEL. I think NSF-61 is a standard that assure the components are safe for potable water. I don't know it has anything to do with a 50 year life assurance? Onboard diagnostics indicates battery life, success of crimp, service needed and operating temperature range

Even with balanced Ph, I wonder that some of the new water treatment chemicals used in public water treatment are going after copper when all conditions line up? I think that sweat copper fittings which are properly installed will outlast press fittings. Lots of bad installs both ways, probably more bad sweat connections. Something causes copper to corrode like that. Flux, electrolysis, aggressive water, maybe a combination. At BES, we like to say not only that We’ve Got It, as in we’ve got every fitting or part you need, but we like to make sure that you will not find a better selection of press-fit fittings or pipe tools at a better price anywhere else too.

Given the right water chemistry they will form little cysts that will eat the pipe. I have to admit opportunity cost is adding up in its favor. I hope I'm not creating and more problems for later albeit my experience with this cooper pipe system makes me wonder if the pipe can't last as long as the joining system whether fretting about the joining is as worth it as I thought.

Of course Luigi Galvani has to be involved. The city water pipes up this way are a mishmash of old oak mains and cast iron growing god knows what inside. Moreso than any other buildings on this same water system, I have notice that this building manifests clogged aerators like going out of style with no question iron oxide amongst the constituents of the clogs. So on another note, we're now ondemand hot water which we installed during the pipe rerouting and replacement in the basement. There was an old gravity based hot water recirc with a half inch branch off the top of each hot manifold returning to the cold water feed to the water heater. It was only marginally effective anyway and a source, in my mind, of festering who knows what being stored with all the crap coming in from the city. In hindsight, whole house filtration would have been appropriate here but I'm only discovering all these issues 45 years down the line from this major replumb - and I must say that the folks who did it wouldn't have known that this house was a particular vector for every bit of crap in the system for some reason. service with 2, 1 and 1/2 and 1 and 1/4 copper piping that had , on the hot side, started to develop pin hole leaks in the hot side basement transits before the risers. See attached picture. That of course includes the opportunity costs of the different systems in labor. I didn't actually get into press fittings until I had to renovated an eight apartment manifolded water Manufacturers can do accelerated testing to predict life cycle if the product has not been around for 50 years, for example.
