Sorry Im acting like a noob here.

What does BSP mean.

if I want a 3/4" outlet from the settlement tank into another filter (both at same level so no overflow) would I be able ot use this?

What kind of pipe fits to these? I presume the standard 3/4 inch pump hose wouldnt. Would i need ot use a small length of 3/4" PVC pipe to fix tank connector to hose?

Thanks,

Daniel
