BRR RODI + PUMP = LOW PRESSURE…

This is correct. Don't use a piercing saddle valve when feeding a booster pump. How is it your original vendor didn't pick up on this?

I never knew this although I’ve also never used a saddle valve. Is it because it can’t pass enough flow through the saddle valve?

Correct. And the pierced hole gets smaller over time as scale deposits around the opening.

Although we stock these self piercing saddles, we try to discourage their use.
