[The Grizz]

Well I ordered one of the 1" model SCWD's and did a little test on it with a DC10000 Pump. Now this is not a total scientific test but its simple for anyone to do to get a close water volume movement value.

I simply took a Rubbermaid tube and filled it with water and had a bucket with exactly 18 liters marked in it. Put a 5' - 1" hose onto the pump and timed how long it took to hit the 18 liter mark in sec's, divided 60 sec's by the time in sec's, multiplied that by 18 liters to get liters per minute & then multiplied that by 60 Min's to get liters per hour.

Then I added in the SCWD with a 6" piece of 1" hose to the pump and 2 - 5' pieces of 1" hose coming out of the SCWD. Did the same time test as above.

Here is what i have come up with:

Waveline DC10000 pump alone was 6480 LPH / 1712 GPH ( little far off there 10000 LPH claim )

Waveline DC10000 pump with SCWD was 5400 LPH / 1427 GPH


SO needless to say i am not impressed with the flow rate out of the DC10000 and have to decide if I just go with it or add in 2 more return pumps.

I wanted to test the OM 4way that I bought used last year but it doesn't rotate, it is one of the magnetic versions and if I had look at it closer or know it was the mag version I would not have bought it.
