      TPR location

      Hi all! I am planning to put tpr’s on the spots marked with red and have them flow in a counter clockwise direction with the skimmer located in the spot marked green.
      Each tpr will be connected to the output of an s&g filter.
      I originally wanted the tpr’s to be in the center but it would be impossible to move that huge mound of dirt under the tarp so I am hoping these locations would work. The barrel filters will be to the left of the pond.

      Rain has stopped me from digging out the rest of the pond. The soil here doesn’t seem to absorb the water and even after 2 weeks of no rain the water level seems to remain the same. I had to use a utility pump to drain my excavation. Guess I’ll have to wait until spring to continue as the soil is so sticky and slippery. But in the meantime maybe i can dig out the trench for the tpr’s while the soil isn’t hard as concrete.

      I can't really tell if the pond is square or not but if one side is longer than the other
      I try and point the tpr's along the long wall side. It doesn't look like enough to make
      a lot of difference though if you're using a single BD.

      The pond is an irregular shape (about 13’ x 10’). It will have one bd. Sorry I don’t know why the pic uploaded sideways.

      Thanks for that, Steve. So once I dig out the trenches I will have to connect 2” PVC from the s&g’s output to each tpr, correct?
      Do both tpr’s need to flow at the same rate since one is closer & the other further away from the s&g’s?

      Right, if they're what you'll be using to feed them just connect each one to a tpr. They don't have to flow the same but
      normally if feeding two different s/g filters from one pump you would put a ball valve on each line so you can balance
      the flow between the two. You may need to adjust the long return because if it has too much head you may need to
      slow it down to keep it from overflowing the filter and you could do that with that ball valve.
      How much higher is the s/g filter outlets than normal pond level?

      The barrels will be completely above ground and on concrete blocks so maybe 4-5 feet.

      Then I think you should be fine. I'd still use the ball valves on the s/g filter inputs so you've
      got flow control over each and remember to follow the rules for gravity feeding flow to the pond,
      i.e., no humps in the pipe level that would cause the pipe to trap air.

      You mean to make the trench perfectly level so the pipe is laid down straight?
      Can I use flex pipe to connect the end of the tpr to the pvc or do I have to use elbows to connect the pipe?
      I saw it here in this video:

      You sure can use flex pipe, that will work fine.

      You don't have to remain level and actually you can't if you need to reach a tpr that his several feet lower than the
      outlet of the filter... but you need to always try and allow air an escape route to either the filter outlet or the tpr.
      Here's some examples of routes that might need to be taken:

      The first two are fine since air (shown by the arrows) have escape routes. The last one is the type to avoid since
      there's no where for the air to rise to except the "hump" in the pipe. There are ways to make it work if it's absolutely
      unavoidable, but it's easier if you can just route it differently.

      Hmm, I might have trouble digging the 2nd TPR location as that is where the patio is. Would it be okay to move it to the left like in my diagram? I’m thinking of placing them 12” from the pond floor.
      Also, could I use 3” pipe for the tpr since the output from the s&g’s are 3” or just reduce it to 2”?

      Sure, that should be fine... you're just trying to get a rotational flow around the BD to keep the
      debris moving away from the edge. 12" from the floor should be fine I think. No need to point
      them down really but if you're not sure they make flanged connectors that have internal threads so
      you could screw in a fitting to point it differently:

      http://highdesertkoi.com/accessories/

      Scroll down to "Flanged Connector 2 inch (SLIPxFIPT)"
      Not sure if they come in 3" though but you could call Steve and check.

      And 3" pipe is great. When gravity flowing returns I always go bigger when possible. With gravity you
      won't get any increase in "velocity" from making the returns smaller, you just increase the head.

      Ok thanks for the info! BTW, I am concerned that my barrel filter's output might be a problem. If you check in the pic, it is facing upwards a bit because of the barrel's shape. Would this be a problem and trap air as the pipes would have to go up gradually before descending? Name:  IMG_5870.jpg

      At the outlet it shouldn't be a problem since the pipe at this point isn't full of water and therefore
      won't trap air. But don't bring the outlet up any more than absolutely necessary or you'll be in danger
      of overflowing the barrel. It's hard to tell from the angle of the picture, but the bottom of the outlet
      pipe needs to stay well below the top of the barrel. Here's a terrible drawing :

      I can't tell the actual top of the barrel but just for an example the red dotted line represents the
      top of the barrel and the blue dotted line is the lowest point of the outlet pipe. The water will
      flow a bit like a waterfall if there is a big drop from filter outlet. The more the water backs up
      in the outlet pipe (depending on the amount of head on the entire run to the tpr), the closer
      you'll be to overflowing the barrel as it fills the pipe... but with a 3" pipe run and about 2k gph,
      I think you'll probably be fine.
