Plumbing Question And Progress Pics Link
Okay, I'm to the point where it is time to start plumbing in my bottom
drain and skimmer tank. The external pump will be fed off of the skimmer some 20' away ( or so. ) The pond will be approximately 10' x 16' x 2.5' deep. Target pump should be a 1500 gph. Seeing as how most pumps I looked at have a 1.5" to 2" intake, I am planning to plumb my bottom drain and pump feed in 2" pipe. At this point I'm not concerned with the plumbing after the pump. Pros? Cons? Suggestions on staying at 2" or going larger, smaller?? Latest progress photos. http://www.bunchobikes.com/pond4.htm |

Latest progress photos. http://www.bunchobikes.com/pond4.htm Stay with 2" on the bottom feed and you can use 1 1/2" for the skimmer line which can tee into the bottom feed line. I would put a gate valve on both lines so you can selectively trim each line. You may want to connect a vacuum to the skimmer line. For the return line (kidda depends on the run length and head), but I would go with 1 1/2" but I would plumb in a waste line Tee with a hose bib for vinyl pool hose. I'd also plumb a line that goes directly back to the pond, bypassing any waterfall... both w/ gate valves to trim. 1500 gph, seems too small, especially if it has 2" and 1 1/2" out, which pump ? jay Sun May 30, 2004 |

It does have to be external and energy conservation a huge factor. Suggestions? TIA. The bottom drain is going to be plumbed into the side of the skimmer box. The skimmer box is a multi chambered box based on a "clarifier." Basically a multi chamber settling box. Chamber one is the skimmer, chamber two allows the bottom drain to feed into it, chamber three is the final settling chamber where the pump will draw from, pulling from the previous two chambers. |

Water level was going to be right above the skimmer opening, 1/4" to 1/2". With a fountain, that could be 1 days evaporation. The weir gives your that latitude and is a much better surface skimmer for bugs. chamber two allows the bottom drain to feed into it, Is by gravity or is this box pressurised ? Gravity or flow ( draw. ) Similar principals are used on a large scale as in a sump clarifier for water and oil / debris seperating in the automotive world. You think that poly box shown in big enough for these types of flow rates... but Im not exactly sure your idea... one thing I always hate is when I can't adjust the trim on my intakes... especially a surface skimmer line. Good luck, keep us posted. jay Sun May 30, 2004 Mark jay Sun May 30, 2004 chamber three is the final settling chamber where the pump will draw from, pulling from the previous two chambers. |

For the plumbing, the pumps are much less efficient at pulling water than
pushing water. Most of the pumps that I have seen have smaller input and output plumbing connections than the manufacturers recommend for the main run of plumbing. It is easy to use a bushing at the pump to reduce the plumbing to the size of the pump inlet. The larger the pipe, the less head loss, like friction, and the easier it is for the pump to give the desired flow. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Mark and Kim Smith" wrote in message ...
