[weileong]

any idea?

[islander]

diffuse meaning?into small bubbles?or lower flow?or lowered pressure?

what u can do is fit a small plastic tubing that fits snugly into ur piping outlet from pump to create low flow or higher pressure.put a higher rated check valve to limit the flow.Or put gate valve to throttle down both flow or pressure.Or put a t-joint with a venturi intake to create a air being sucked in and produce bubbles.if i do not enlighten u pmed again.i'm no experienced plumber but i face pumps , compressors,pipings everyday iduring werk..
