housing does not have the bleed hole as shown in
Bulents_Cosmo_pump2.jpg.  Did it come that way or did he add that?

I've resisted adding a purge line as it is an additional failure
point.  A petcock or Schrader valve would be preferrable.

I don't recall Bulents pump having that feature.
Bulent's pump had the bleed hole as stock.

What did you do about the bypass?

I see you are using the Wiggins couplings. Nice work!

That looks like the highest point in the system.
Where is your pressure container and pressure cap?
If it is above this point which it should be you
should not need this tap.

Mark, my pump (Cosmo) was very tall and had dual thermostats. Paul
volunteered to cut it down and made a block off plate inside. I
installed a 1/8" NPT hose fitting at the highest pount and let any
air escape to my pressure tank. It works very well sofar?
