Pcw-250

A ball valve at the delivery point would be needed to throttle the flow down to a more manageable rate. It would probably be better suited to flood coolant on a mill or lathe than a power hacksaw.

Thats a good price for that pump, but thats huge compared to the ones we are talking about.
I have a big one in the pond but it's for the water fall, I forget how many liters and hours it is.

Mine is a water feature pump, about 320 L/hour with 1.5M head. That works out to ~90 ml/s but the back pressure tap restricts that to somewhat less than this.

I am also using a water feature pump but be warned that any fine steel particulates will be attracted into the brushless motor and grind away the insides slowly.
Put a good filter and check regular.
I have two filters on mine and might add a large magnet in the tank.

Hi Russel, I also have a round speaker magnet around the drain hole in the gutter, and I find only a little bit gets past it because all the shavings then acts like a magnet. The one in the funnel then picks up anything else.
If you have room try one in the same spot in you gutter.
