Indeed.

I was going to bolt something like a PC watercooling block to it to give
a nice high area passage for the water.

I also discovered that the solenoid will probably get rather warm. Im
going to have to make sure this doesnt heat the water! spec says
solenoid at 100% duty will hit 90 degrees! I dont think this will carry
to the water too much though looking at the design. We shall see.
