![]() Okay, you guys that have external pumps and uses 55 gal drums are going to have to help me here. My pump is suppose to push 1500 - 5400 G.P.H. If I have the pump pulling from the 55gal drum to push water flow in the pond, I was thinking if it max's 5400 how can I get the water to flow into the drums being gravity fed fast enough without the drum going dry. I'm go have 3 drums. One the settlement, one with loads of filter mat and the other empty with a hair of filtermedia and this one will be the one the pipe from pump pulls from. Also the pipe going to the pond I was going to have a venturi thingie set up. Did I explain that? I am so tired. Priss |

If you do your plumbing with 4 inch pipe, there should be very little
difference in the elevation within each of the drums and they will not go dry. If the pipe size is small, then you run the risk of having the pump run dry. I have an external pump feeding from a bottom drain and vortex filter and do not find that I have a problem. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "pmwebdesigns" wrote in message ...

You don't have any pics of your pump and filter set up do you?

Sorry, got pictures of about everything else but filter system. If you
would like, I will try to take some and post them. The bottom drain is a vertical piece of 4 inch pipe, going down into a deep spot in the pond. It flows into the vortex filter with all 4 inch pipe. The outflow from the vortex steps down to 2 inch pipe going into the shed. In a hole in the floor of the shed, below pond water level is a "T" going to 2 sequence pumps, one feeding a BBF-2 bubblebead filter, and the other feeding a 6 cubic foot bead filter. Each has its own return to the other end of the pond. One return currently feeds a trickle tower, the other an upflow gravel filter. The trickle tower and upflow gravel filter are scheduled for replacement this year. Do to total length from one end of pond to back of shed, it would take multiple pictures. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "pmwebdesigns" wrote in message ...

Hi Priss You can calculate the head loss from charts like at http://www.mdminc.com/friction_loss_chart.htm For 5400 gph flowing into the drum, 100 feet of 4" pipe will result in the water level in the drum being about 1/2 inch below the pond level whereas 2" pipe will stabilize at about 12 inches below. This scales linearly so for 25 feet of pipe the numbers are 1/4 as large. Fittings add to this, see the chart. Fittings are speced as equivalent feet of pipe so the calculation is: 1) add up all the feet of straight pipe 2) add the equivalent feet of fittings 3) read the pipe chart at the desired flow rate and pipe size to see the head loss for 100 feet of pipe 4) figure the proportion for the feet you have (50 feet is half, etc). Also this is best case, don't forget things like clogged filter media and intake screens :-) Hope this helps Andy PS Or you can just use "Rich's Rule": You can't go wrong with four inch pipe |

Priss,
Did you check out my filter design/diagram on my website? Similar to what you describe below. ~ jan http://users.owt.com/jjspond/ ~Keep 'em Wet!~ Tri-Cities WA Zone 7a To e-mail see website On Tue, 11 May 2004 18:47:59 -0400, "pmwebdesigns" wrote: Okay, you guys that have external pumps and uses 55 gal drums are going to have to help me here.
