good morning YouTube so this is the inside of my Breville barista Express so I was poking
around inside here looking at doing a water pump replacement and in the process I noticed up here
there was some signs of a water leak there was like white water residue around this valve here
you can see down on the top of the metal here and I brushed some of it away but it was coming out of
this area and I just happened to touch that hose and it did that this is the hose barb that was
inside of that hose broken off it's anyway that pose here connects to this valve this is your
hot water and steam valve and right down there is where it connected and it just broke off but if we
look at the end of that there it's just a really paper-thin piece of metal left I don't know if the
inside of this corroded out or what happened in there I wanted to figure out what I was working
with so this hose here is probably six millimeter inner diameter or roughly quarter-inch this hose
barb was probably six millimeter hose barb that was cast into this this is probably some sort of
zinc alloy casting metal when I first got here this inside was all plugged up with corrosion
so I took some drill bits and I started with a number 24 bit and then worked up one drill bit
at a time this is a number fourteen bit and it was finally able to get all the way in there and
get that hole opened up because I wanted to get to some clean metal so that I knew what I was working
with I need to put something like that back on there a little hose barb that I can hook this
hose to I kicked around a few ideas some things I came up with I have a quarter inch hose barb has
quarter inch pipe thread fitting on there which you know that's that wouldn't work at all it's
way too big but the hose barb itself is the right size to fit in the hose there so that would work
for the hose so one other thing I was thinking of is I've got some brass bolts so I was thinking I
could drill and tap a hole in there and then run a bolt in there and then take the bolt and drill
a hole through the middle in my lathe but what I like to do when I'm faced with a repair like
this is I like to consider all the possibilities for repairing this before I start doing anything
and then have a plan a and a plan B and a Plan C so that if one doesn't work I've got someplace to
go to and the reason I like to work out the plans ahead of time is I can make the hole bigger but I
can't make it smaller so what I like to do is work out my options in increasing order of the
size of the hole that I need and start with the smallest hole option first if that doesn't work
I can always drill the hole out and pick it bigger and do something else with it when I finally got a
drill bit to clean out some actual metal particles here in fact there you can see there's some of the
metal shavings so I'm getting clean metal out of there now this like I said was a number fourteen
drill bit which is a hundred eighty mm this hose barb quarter-inch on the outside 250 thousand s
the drill just barely fits in there so one option I came up with is some brass tube 3/16 or four
point seven six millimeters and three sixteenths of an inch is one eighty eight thousand 0 so
this tubing is just barely bigger than that hole right now so that's plan a is we'll just cut the
end of this thing off cut off a length of tubing and shove it in there and if that doesn't work
then what I'll do is keep this I'll have the tube inside but now I've got the thickness of
the tube inside of the hose barb and I can thread this to match this and then I can drill that hole
out I have to drill it about ten drill bit sizes bigger I've got to go to a number three drill bit
and then I could tap some threads and I could shave this down to quarter inch thread it and
then screw that in place with some Loctite and then if that fails Plan C is to go to the bolt
because I'll already have a threaded hole in there and I can just get a brass bolt drill it
cut the head off screw it in there and hook the hose on to the end of the bolt basically okay
starting to prep this hose barb so what I did was cut the threaded piece off there just left
with this what I really want to do is preserve as much length of this part as I can in case I need
to thread it for one of my backup plans the hole actually goes partway through the hex head here
I'm just gonna keep going like that I just want to take light cuts because I'm
not sure how strong that hose barb is the material law that's what's left yeah 277
that's what I want to do is take this down to 250 which is quarter in or if you want
millimeters were right at 7 now what I want to do is I'll probably take this section and
maybe take that barb right there off that'll give me about a half-inch that I could thread
this down little under a quarter inch okay you've got a 3/16 inch bit in the
drill I was hoping I could drill it with my little micro Chuck but this
is the biggest bit 180 mm that'll fit in there can't quite get that fit in there so
ok I think that worked pretty good there's the hole and let's see the tubing should fit in there
now that's pretty snug fit once it gets in there yeah I think that's gonna work so if I just keep
this point to the outside there and I can slide that in and just have it bottom out yeah figure
that way I can just bottom that thing out and then we'll just slide this piece over the other
end okay I think that'll do it so I've got my hose barb slid over and what I'll do is just slide this
in and find where it goes in as far as it wants to okay there we go I just pushed the tube out
of the hose barb aways is up a little jig here with a hole in it oh that it's tight yeah there
we go just wipe that off with a little isopropyl alcohol and all the fingerprints off of there and
then I think I will repeat here that should be enough on there let's see there's my bevel up
that way so I want to shove that in I guess that's their figure I'll just leave it sitting here let
the this stuff cure up yeah hopefully the brass will be a better solution and if that retaining
compound does the trick all I need to do is put this hose back on so that's the original hose
clamp I'll see if I can get that back on there we go so that's what it looked like let's see if
I can get that on there on the right way yeah that might be that might be tight enough yeah
get that sorted out once I let this cure for a while but that should solve my water leak here
so there we go and yeah it wasn't a terribly expensive fix I'll put a link to this tubing
on Amazon it was a little under five dollars for the one foot section and then a hose barb I just
picked up at the local hardware store or they're probably $2 apiece something like that so you
just want a quarter inch hose barb it doesn't matter what the other end is but yeah I think
I think that's gonna work the thing is this valve is no longer available according to the website I
looked out they have it listed as a part number but they say it's not available from Breville
anymore hopefully that fix will work so we'll test that out once I get the pump replaced and I think
that should do it yeah if you have any questions about that post up in the comment section below
and I'll put links to the various parts I used in the video description if you like this sort
