It works - though I would like a bit more flow. The pond is fitted with
1.5" tubing. Would upgrading to 2" make a difference?

Today I attempt to install a new Sequence 7200 pump on my 2500 gallon

pond.

Will keep you posted and post some pics when done. Keep your fingers
crossed that Murphy's Law is broken today.....

~Power to the Porg, Flow On!~



larger pipe = less restriction = more flow

I know this is for PVC, but it shows the relationship between different
sizes



Table1: Saturation Flow Rates for Schedule 40 PVC
Pipe Size Approximate Saturation Flow Rate
1 inch 25 GPM 1500 GPH
1 ½ inch 60 GPM 3600 GPH
2 inch 150 GPM 9000 GPH


Table 2: Maximum Recommended Flow Rates And Pump Sizes
for Various Pipe Sizes
Pipe Size Max Pump Size Approx. Flow Rate with Max Pump Size
1 inch 1/3 hp 15 GPM 900 GPH
1 ¼ inch ½ hp 25 GPM 2100 GPH
1 ½ inch ½ hp 45 GPM 2700 GPH
2 inch 1 hp 75 GPM 4500 GPH
2 ½ inch 1 ½ hp 110 GPM 6600 GPH
3 inch 2 hp 200 GPM 12000 GPH
