good afternoon YouTube so we're gonna test this hump that I picked up for the Breville barista
Express so this is supposed to be a 52 watt Ulta model II f-type e FP v and I figured what I would
do is s this pump out before I put it in make sure it works and then I want to see how far it shoots
water just to do a CAD Hawk pressure and flow test so what I'll do is I've got my Clif quick test
here so I've got that plugged into the FCI outlet and then I've got a little cable harness hooked up
to the pump so when I close the quick test the pump will start and right over here I've got a
bucket of water and a clear PVC tube dropped into the water so we'll suck some water up the tube out
the pump and then we'll try to shoot the water out of the small tube and see how far it goes so let
me switch over here get lined up so what I'm going to do is close the cliff quick test and we'll see
if the pump works here and there we go sucking up water let it build up and pressure there
the far bricks that are under my tomato plants that's 22 feet and I was just getting to the
base of those blocks that is the flow and pressure out of this new pump once I get the
old pump out of the machine I'll run this same test and just see how far it pumps because if
the old pump has low pressure it's probably not going to shoot the water out as far that would
be a reasonable test of pressure right yeah we'll come back and test the old pump once I
get it pulled out of the machine and see if there's any difference okay YouTube so this
is the original pump from my Breville barista Express and got the original safety valve on
there and I've got this plugged into my cliff quick test so we can supply power
and we'll see how far it pump the water here getting about the same distance over there
maybe a little bit less the new pump was giving up on to the bricks on the side of the shed this
one is getting this the short of it but I think I might see part of the problem right here if you
look there's water dripping out of this safety valve so I think it may have actually been the
safety valve that was the problem I don't have the water in there that's gonna leak a little bit but
let me see if I can find a ring or something to put in there okay so fun this small Oh ring that
might seal this up see if that water is leaking out of the valve or just out of the seal there
so that one might be too big but let's see what happens here yeah okay yeah you can see
it's still leaking out of the end of that safety valve there looks like the pump pressure is okay
but I'm I'm thinking this valve was probably bleeding pressure off there's a little clip on
there of some sort oh I wonder if this thing is adjustable yeah so this just holds the it's kind
of like a little lock nut so yes I read someplace that this thing was possibly adjustable so maybe
that's been the problem with my machine it's gone through cycles where the pressure gets really low
and then it oscillates the pressure gauge would go up it'll drop and it just oscillates between
high and low pressure so I was thinking it was the pump but it might be this thing because there's
probably a little valve and a spring in there and then this center part pushes harder on the spring
takes more pressure to open I think I'll have to figure out if there's a way to test these
the only thing that might do is take the pump and you can take this pump head off and inside
here there's an o-ring and a little plastic ball that's the check valve and that little plastic
ball supposedly so I might pick up a rebuild kit for this and then just compare the size of the
ball in here to the size of the new ball in the rebuild kit and see if there's any difference it's
supposedly the little plastic ball gets smaller and smaller and smaller until it doesn't seal
up very well anymore and then that's when you replace it if I can screw this into the pump
and then maybe get something to put into a gauge for this end because then I could put a pressure
gauge on and then let the pump run and see where this thing blows off at because I'm guessing it's
probably something less than 10 bar which would cut down your espresso brewing pressure yeah if
you've had any experience with these post up in the comment section down below and if I get any
follow-up testing I'll put those videos over here on the left side and as always thanks for watching
