it's ok to disagree
imho and through experience with mine the JV is now continually flowing with coolant, whereas afore it did jam and cause problems.
to summarise it causes less problems without it
Yep when it jams it certainly cuases grief! I suppose that with no BB the water will just shot up into the tank and then a bit will get sucked back down again - that's how I had it with the EWP.
