Plumbing With Pex Pt 2

Electric Bugaloo.

You know what two diy'ers should never, ever try to do. Replumb a tri-plex in a single day.
Wow, my back hurts....
Well, not really replumb the entire thing, but one of the units and the main floor of another unit...
We prepared as much as possible by doing as much work ahead of time as we could....but still...

See this picture below? that was only half of the amount of copper piping we removed.

The water supply piping in this house was really, much screwier than we could of imagined...
One mystery was solved though. The mystery as to why it took forever to get hot water in the MB even though the water heater is almost exactly above it......

For some unknown reason the hot and cold water supply lines to the MB start in the attic, go all the way down to the first floor, shoot over horizontally for like 10' and then go waaay back up to the MB....seriously, WTF...

Second mystery that we didn't even know was a mystery.
Off the main incoming cold water line was an old looking 3/4" galv water pipe.
We searched and searched and we determined that it was just some old abandoned pipe that didn't matter. I mean, there is a giant 1 1/4" cold supply pipe going straight up and appearing to supply cold water to the main house.

NOPE! Gosh-darned thing is supplying cold water to two bathrooms and the top floor laundry closet...
I am at a total loss as to what to do about it....why, oh why did they not just replumb the two bathrooms from cold water off the giant 1 1/4" riser?
One of the bathrooms is literally 3' from the attic WH and that big supply line?  GAH!
We, and by we I mean Igor who is much slighter of frame, are going to have to do some more
investigating to figure out what-the-what...

Now a bunch of pictures of pretty red-white-blue plumbing lines.
The lines start at the manifolds and then branch off.


Ugly shots of a bunch of pex....

Messy huh? Its all temp supported for now.

The tie-in to that big riser pipe.
You can see the hot tie-in to the cats bath also.

Screw-up #1
This T here feeds both hose bibs.
I cut the little tie in piece too small....When you do that the PEX expander
tool will get stuck in the plastic T and it will crack the T.
This spot leaked pretty well until we put the band clamp on it.....

Something you should never do part 2
We weren't even ready to pressure test the system until 6pm.....that, was a baaad idea...
Because, if everything wasn't perfect...we'd be chasing leaks till 3am.
Luckily, none of the sweated copper fittings leaked!
None of the PEX connections leaked except where we had to put in a push-to-connect T...
Turns out, both studio apartments have their own 3/4" cold feed lines...surprise...
Also, this would be the first time firing up either of the tankless units.....
So, so much coulda gone wrong....I was contemplating a hotel stay for the family...
Did I mention that several members of the family had food poisoning...and we had no water...
All five toilets got used that day and where in desperate need of flushing...yum.

Screw-up #2
See this nice little ice-maker box...we forgot to turn its valve off...
When we turned the water on a impressively large stream of water shot
out of the box exactly hitting the units electrical sup-panel....
Hurray!! Water plus electricity equals fun for everyone!

Another thing we didn't count on, was just how much water was left in the
horizontal runs of pipes...whenever we would cut some pipes we'd get at least
a half gallon of water out...on us...we were both soaked by the end of the night.

'Nother great thing that happened...I cut a line and the water shot out and exactly hit
our battery charging station!! Soaking all the chargers and batteries! Yay!! Plumbing!!!

Oh and about 3/4" of the way through Igor broke our only good soldering torch...we had to
rely on the back-up crappy torch that just doesn't get hot enough...

We got the bulk of it done and there was hot water to take showers, wash dishes and clean
clothes with....and I'm still tired and sore from this adventure days later....

Something Silly,
Along with un-F'ing the plumbing Igors been working on the wiring...all this
romex you see here was just random pieces that they used to wire things
together...with a buried junction box every 5'. 
Now, we walk through here and pretend we're Rapunzel with loooong
beautiful hair....

No, you can't have our copper scraps.
