Topic: OT I HATE Plumbing (14 msgs / 537 lines)
1) From: miKe mcKoffee
Or why I walked away from the Bricoletta and starting typing before the
sledgehammer came out. 
Replacement T connector arrived this afternoon. Ok, installed and tightened
all fittings as tight as possible. NOW slow leak from male compression
fitting end, other end of T which had crack and previous leak! Took assembly
out and tightened until fitted 12mm wrench slipped partially stripping the
line connecting nut. Leak almost stopped, but not quite. I HATE PLUMBING AND
COMPRESSION FITTINGS!!! And this frackin' line is the feed into the frackin'
boiler. May have to manufacture a whole new line with new compression
fittings. Going to try teflon taping the male thread of the connector, which
you normally don't need to do with a compression end. Not so sure teflon
tape will hold up to ~9bar pressure anyway but gonna give it a shot, or is
it under ~9bar or only line pressure? Don't want to think that hard and who
cares, off to give it a try before resorting to dynamite, I mean off to
hardware store to manufacture new line...

Mike:
your compression ring most likely had a nick and when you cranked down on it, all hell broke loose. teflon tape will not help you are correct but try a bit of JB Weld, you will smile in the morning!!
heck they even have that new 3 minute J B Weld. 
then just cut and weld when it poops out the next time.
ginny
gorilla glue is also fantastic but you must wait overnight and it does expand a bit!!

I don't know if you're describing a 37° flare fitting- it's straight
threaded and does not seal on the threads.  Teflon tape can seal pipe
threads, but will only botch compression fittings like we had on a 3,000psi
MTS  testing system or the associated 12,000psi intensifier.
At either pressure, a leak would have been deadly. I couldn't believe the
tape that was causing hydraulic oil to weep from compression fittings. Some
fittings were severely overtightened and still wept oil.
More tape and tighter is the way.

First DJ,
VB? Went over my head...(very black?)
Ok I'll cop to it. I hate filling an espresso machine tank all the time =
more
than I hate plumbing:-)  Heck I ran plumbing to float-valve direct fill =
Miss
Silvia way back when! As luck or fate or actually logic would have it, =
the
teflon tape on the T male threads of the compression fitting end did the
trick. Logic because duh, it was barely seeping so not under line 4.5 =
bar or
when on pump pressure 9 bar hitting the tape. Hours later (including =
pulling
after dinner Misty Valley Café' Crema Americanos) fitting dry as a =
bone.
Bricoletta all better, now to find storage space/location indoors for =
the
backup/vacation espresso machine Audrey. (Until I can afford a good =
lever
machine that'll double for vacation travel duties:-)
Funny thing, after verifying no line pressure only leaks when I first
powered up the Bric' with the cover off was amazed as the tank filled. =
At
first couldn't hear the pump and thought I'd screwed something up! No, =
just
those dang vibe pumps are so loud the rotary was whisper quiet in
comparison. Especially with the covers off! When covers on noisier =
because
of the cups etc. on top rattling around, not the pump itself:-)

i try to make a habit to not use compression fittings more than once.  or,
at a minimum, replace the compression nut each time.  also, no teflon is
needed with compression fittings, it can cause them to leak.  finally,
unless using hard piping, make sure to coil the copper line so there is som=
e
flex built into the line.

Normally I'd agree but these aren't "standard" compression fittings with
ring around the tube but rather factory lines with compression male end hard
attached. Maybe I'm using the wrong term for the fitting type (ain't no
plumbing expert!:-) since it's not a compression ring fit to the line but
rather the curved line end compressing to the female fitting end...

Do you mean the end is flared into a truncated cone shape?
You can get a flaring tool to form the flare at the end of copper tubing,
they're inexpensive.

those stupid things always leak. :(
 i think there should still be a plastic compression nut used with them.  id
just replace with a pipe to john guest fitting.  cut the pipe if you have to
so its smooth and solder the adaptor on. at least you know it wont leak.

The end isn't just "flared" but rather ends in a solid truncated cone. This
is a common tube end type used in higher end espresso machines... Bottom
line it's not leaking/seeping at all 12 hours later and I'm not concerned.
Put the cover back on this morning. The teflon tape worked fine to stop the
slow seeping. I am going to be prudent and order a moisture detector to
cut-off water supply should a leak develop in the future!

miKe,
After my flood earlier this year, I installed a leak detector and I have =

it does work.  A couple of weeks ago, I removed the drip tray to clean =
it and dripped a few drops of water. (less than 1/2 tsp.)  While I was =
rinsing the tray, I heard the valve close and the alarm sounded. The =
water had hit the corner of the paper towel and wicked to the sensor =
which did its duty.  I replaced the paper towel and reset the valve and =
all was normal again.  I feel confident that I won't have a flood again, =
unless, of course, the line breaks before the valve which is highly =
unlikely.

Sorry, talk about a burnt-out geek brain, of course VB a.k.a. Visual =

It just goes to show, for me the paranoid thought of coming back from =
