I got my first controller last week and 2 flow meters for my return pump lines, now I was expecting to see some reduced flow, I guessed about 50%, due to several bends, and under rock work return piping on one line and an ocean motion on the other return line... I have 2 8000L Jecod return pumps... guess what flow I'm getting at full power?????
1975L/hr on the under rock line and 1618L/hr on the ocean motion line, it was 1459L but I removed the direction beak and it rose 150L... that's less than 25%!!!! I have a head of 48" so not huge... it just goes to show how much the pipework and fittings reduce the flow, who would of thought the directional beak would of had such an impact... I know the Jecod pumps are not the most powerful, I might try to get my hands on a more gutsy 8000L/hr pump and see what the difference is...
