Re: Brewtus III Pressure Issue

Ok, being amazon the '2 day free shipping' ordered friday was due to arrive 
tomorrow but instead the mailman knocked at my door this sunday at 10am.

Thats good news. More good news is that the new pump appears to be a drop 
in replacement and seems to work fine.

However, the pump replacement was more difficult than I expected. I might 
have been approaching it the wrong way, maybe my mind wasn't prepared for 
the difficulty but I found it pretty desperate.

With left and right being relative to front of the machine:

There is "pump assembly" connected to water tubes on left and right. Tube 
to left draws from tank, tube to right goes to brew area.

Pump assembly is pump, then pressure relief valve (with its screw control.) 
To replace pump you must separate it from the pressure relief valve. But 
the right side of pump can spin freely... I found there was no room with 
the tools I had to undo the pump from the pressure relief. No confidence 
that I could put it back properly, so decided to remove pump and rubber 
angles.

Pump is held in place by 3 rubber "angles", the angles bolt to the base 
plate of the machine, the pump slides through.

To get pump out I undid the bolts on the bottom of the machine that feed to 
washers and nuts. Then disconnected tubing from left and right side of pump 
assembly, then pulled it out. Then use a 12mm thin wrench and a 14mm wrench 
to separate the pump from the rest.

Attach new pump, then thread assembly back into place. Now comes the fun 
part. You need to feed the washers and nuts in, there's no room. Keep 
dropping and losing them. I even undid the portal under the boiler to give 
my fingers more room.

Took me about 6 tries to get those washers and bolts on.

Whole job took me just under an hour and was pretty damn fiddly 
and desperate. In hindsight it would habe been much easier to thread the 
bolts from the top out the bottom, use the nuts on the outside of the 
machine. Oh well.

For time comparison, removing both boilers was 40 minutes, installing both 
was an hour, pid upgrade was 40 minutes.
