More keel cooler piping

Here is the return leg of the 2 1/2 inch keel cooler piping getting installed. Unfortunately, the connection for the upper keel cooler is above the finished deck plates, so I have a potential air pocket trap in the piping at this end. You can see the 1/2 inch brass plug I temporarily have in this fitting I welded in. I am going to install a small bleeder valve here later to let out any trapped air.

A 2 1/2 inch tee with a threaded plug is at the top of each leg. I also installed a thermometer and welded in fittings for the connection of temperature sending units.

The orange plugs are to keep dirt out of the coolers until the final installation.

And here is the supply leg for the same cooler awaiting sandblasting and priming!

    A Boiler hot water air vent will get rid of the air automatically.

      Hi Bill – thanks for that advice! I’ve looked at the ones in Home Depot, but they seem a bit fragile. I will check McMaster Carr and see if they have one thats a bit beefier.
