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..... Gary |

Wishes, and good vibes, sent your way! ~ jan :o)

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? "~ jan JJsPond.us" wrote in message ...

Thanks - it actually looks pretty good right now since the filter was
cleaned. But it looks as if I should change out the 1.5" to 2" if I want a bigger waterfall. From what I can see, it looks pretty significant. Anyone out there change out pipe size and notice a big difference? There are some areas where it must stay 1.5", such as the pipe that is cemented into the waterfall. Will this negate me changing out the rest of the pipe? Is the flow only as good as the smallest pipe size?

Based on the flow rating of the Sequence 7200, the friction loss for 1.5
inch pipe would be about 50 foot of head per hundred foot of pipe, which means the pump is not capable of getting that flow. For 2 inch pipe the head loss is about 11 feet, and that is reasonable. For the 1.5 inch pipe, the flow is probably about 1/2 what it is capable of. -- RichToyBox http://www.geocities.com/richtoybox/index.html "gng" wrote in message ...

Thanks - so the big question is whether it would make any difference at all
if I changed out the input feed tubing with 2" but left the output (to filter, uv, and waterfall) 1.5". Right now the waterfall is looking great - should I just forget about it?

I does make a difference on the suction side also.
i.e. If you get your self a coffee stir, and a soda straw, and try to suck you soda (pop to all you non-Pennsylvanians) through both of them you will find it harder to suck it through the smaller straw. So it is with a pump, the smaller the suction piping the more the pump has to work, thus less flow. The smaller the discharge piping the harder the pump has to work. Thus less flow but more pressure. -- /\/\ike Chagoi http://ourkoipond.com gng wrote: Thanks - so the big question is whether it would make any difference at all if I changed out the input feed tubing with 2" but left the output (to filter, uv, and waterfall) 1.5".

Changing the input side will do more to increase flow than changing out the
output side, making water available to the pump. A restricted input will cause the pump to cavitate and wear prematurely. If you are happy with the current flow, then you do not have to increase the discharge pipe size, but by changing it you would at least double the flow. -- RichToyBox http://www.geocities.com/richtoybox/index.html "gng" wrote in message ...
