dcbeerboy...I just had the same problem with mine, breaking the head in the same way. I swapped out to the bronze head, but just a heads up, my impeller post had to be changed out too, as well as the gasket. The brass head took a slightly larger gasket, and my post on the plastic head was a slotted cut, but the bronze was a reverse thread. YMMV, and I may have gotten new old stock that was an older design.

The older style bronze heads had a reverse thread shaft....all the newer style heads have the same shaf as the plastic ones...all press fit into a "D-slot" in the pump head.
And yes the O-rings are different between the two. Everything else will all swap over between the bronze and the plasic versions.

Ya Bronze contains LEAD ie not food safe it can kill you. Some bronze does not have lead, but all bronze have zinc. In large quantities zinc is just as bad as lead. I will stick to Stainless Steel, pay the money and dont worry about it!

A 20 minute flush with vinegar and hydrogen peroxide will remove any lead that is on the surface.

that is interesting, I did a quick look up on the topic. Here is what John Palmer had to say about it:

Cleaning Brass
Some brewers use brass fittings in conjunction with their wort chillers or other brewing equipment and are concerned about the lead that is present in brass alloys. A solution of two parts white vinegar to one part hydrogen peroxide (common 3% solution) will remove tarnish and surface lead from brass parts when they are soaked for 5 minutes or less at room temperature. The brass will turn a buttery yellow color as it is cleaned. If the solution starts to turn green and the brass darkens, then the parts have been soaking too long and the copper in the brass is beginning to dissolve, exposing more lead. The solution has become contaminated and the part should be re-cleaned in a fresh solution.
