Pond PVC? :-)
I was going to use ABS for my bottom drain, but each coupling is another
chance for a leak and I need about 3 joins. Plus the couplings will make the pipe that much bigger, something I don't need for my tunneling project. But I was on the Home Depot site and I saw this flexible PVC. It's funny looking stuff, kinda looks like non kink hose with the ridges filled in. It looks different than the standard sprinkler PVC I've seen. I checked a couple of pond sites and one carries the funny looking stuff and the other looks more like the standard PVC I'm used too. But it's a little hard to tell from the blurry pictures. So does the funny stuff exist or is it my imagination? How does it compare to the standard flexible PVC? |

It's generally less susceptible to kinking and crushing than the standard flexible pvc. When it comes to construction of the bottom drain, the bigger the inside diameter and more solid the attachment and support structure (especially at the drain) the better in the long run. That's the last part of the build you want to deal with doing over. grin joe |

Joe is right about the size and firmness of the drain. How big had
you planned finally to make it? If it is your main bottom drain, you will want it pretty big. If you put plenty of cement on the joint, you should have no problem with the pipe joints (easier for me to say than for you to do). Our drain system is 2" rigid pvc. No problems for a decade. Jim |

I doubt I'll dig it up again. If it should plug I can easily shove a water hose through it, or plumbers tape. Regards, Hal |

4" is better! Will it ever drain a pond in a HURRY! Jim |

Even if I had to build a mock up to get it right. Regards, Hal |

Jim Not likely the bottom drain is hooked to a three barrel filter on the same waterline as the pond, with the pump in the third barrel and the pump is 1800 gph. It can only pump the barrels half empty except the last one, so the pump would only remove half the water in the pond. Regards, Hal |

I don't plan to dig up the existing pond until I'm closer to getting the piping done. I bored the concrete on the weekend, but did not start the 'tunneling'. Pesky rennovations saved me from the 'good stuff'. :-) |

No, in fact because there was about a 1 in 4 foot drop/taper to the center, it was sort of a stress point, since it was bolted, glued into the liner at that point and pulled, gently, from the sides. I couldn't work all the wrinkles out because of the tapered bottom and wouldn't allow more than a couple inches difference if I were doing it again. I can't see the liner needing any slack. I used Permalon as a liner, but rubber will give a bit and .040 should work fine as well. I'll have to work out the kinks once I actually lay my hands on one.

Pesky rennovations saved me from the 'good stuff'. :-) The reason I said I would take my time planning the concrete, the instructions with my bottom drain were a bit vague to me, so I calculated for myself how much space I wanted between the dome perimeter and the liner when it was set. The tapered bottom that I wanted made it more difficult to make measurements under the dome, but I was pleased when I finished. A year or so later I noticed fry in the filter barrels and found they could pass freely under the dome and when I checked the dome clearance between it's perimeter and the liner it had moved enough to allow the opening to increase to what looks like more than 1/2 inch maybe 5/8. That wasn't a serious problem, just wasn't what I expected. With concrete and a mockup of the drain I could have formed exactly what I wanted it to be and it would be exactly as I formed it years later. The instructions warned me to use cement, but I had plenty of confidence in Georgia clay. Regards, Hal |

Bottom Drains cemented in.
Here we deal with sand, sand mix with bigger sand (also called rocks. And stuff out at the D.pond they call clay (ick). Anyway, before I ever did a bottom drain, luckily another ponder had done it in his soil which is the 2nd above. He didn't cement it. A year later he decided to go deeper and found that the drain had settled several inches and stretched the liner to almost nothing. Talk about lucky it didn't give way. So the demo.pond in the 3rd type of soil (clay) above we cemented in. My lily pond, in the 1st type, sand, cemented in. Not worth the worry, and it is such a little bit of cement it could easily be dug out. Though I'm the type to build new not remodel. ;-) All 3 of the above were 3" tetra drains. ~ jan ------------ Zone 7a, SE Washington State Ponds: www.jjspond.us |

You guys are never happy, you're always finding ways to give me new pondmares. I get the tunneling started (almost) and you start talking about Bottom Drains sinking to the tenth level of HELL! Sheesh! ))))))))))))))))))))))))))))))))))) |

POND EQUIPMENT HORRORS
My father taught me one simple Murphy's rule. "Make a hole and water
will find a way in." My corollary is "make a hole and water will find a way out." I have a pond principle ...KISS. A properly constructed veggie filter will: remove silt by passive settling. remove nutrients by plants. look good, enhance the pond. be constructed so that if for some reason any part including the return is blocked, the water will overflow back into the pond. it requires a single pump with no doodads attached. need almost no maintenance!!!! Mostly men, but sometimes women, get excited by and wrapped up in RUNNING the pond with EQUIPMENT. |

Noted on a pond tour ~
women were all clustered around looking at fish and plants. Men all clustered around the filter setup. The more elaborate the better ;-) k :-) |
