Bottom Drain
"Lee B." wrote in message ... According to the "experts" you should have one 4" gravity fed drain every 10'. To work effectively, you should have a 1/2" drop per foot to the drain. Don't forget the anti-vortex cover over the drain, or it will merely suck the water from directly above instead of being forced to draw the water from the bottom. 4" drains are preferred because they will not clog as readily, and if an inquisitive fish *does* go down the drain, it has room to make it to the settling tank on the other end without getting stuck. DIY types can jerry-rig a bottom drain very easily using toilet bowl flanges (one below the liner and one above) and terra-cotta "bowl" type planters for the anti-vortex. If you can get the type of anti-vortex that has an airdome attached, it will accomplish two things: a) it will aerate your pond for you, and b) the rising bubbles actually draw the bottom stuff towards the drain. snip My BD is a DIY...although I never put my DIY diffuser on last year. I think this year, I will be doing some swimming to get that done. Right now, I have the pump running to see how it works to remove leaf matter. So far, not so good without the diffuser. -- BV. www.iheartmypond.com |

Looks very interesting Bonnie.
Thanks very much! Priss "Bonnie" wrote in message ... pmwebdesigns wrote: No actually it was great! Thank you very much. You wouldn't believe some of the smart comments I got from another forum. The pond I have now is 5x11 3½ ft deep. I'm expanding next month to 15x15 4ft deep. I want to do this pond right so I don't have to mess with it again except to clean. I didn't have a bottom drain on the other. Didn't know anything about one until someone mention I needed one. Trying to make everything I can because on a one salary it isn't much. I just bought Greg's CD http://www.geocities.com/bickal2000/pond.htm so hopefully I can follow that pretty good. I am not a handywoman. lol I bought a sequence pump, huge pump. Liner will be on the way next weekend. I'll have mine in the middle of the yard. It will be close to my back patio. You got pictures on a website? Priss Hi Priss, My pond is also close to the house. I wanted to enjoy it year round and I do. I didn't put in a bottom drain at first but I have added one, using a retro fit drain. This way I didn't have to cut my liner. My web site is pitiful right now. I started to work on it and had to stop because of other work, but it does have a few photos -- Bonnie NJ http://home.earthlink.net/~maebe43/ |

Do I understand what you're saying to mean that you have no cover above the
drain? If so, then that's your problem.. Water will take the path of least resistance: it will draw from straight above rather than be forced to suck from the bottom. Experiments were made using the lid of a trashcan for a mold, then filling it with concrete with little PVC "legs" to keep it elevated above the bottom by an inch or so. It didn't work too well, because there wasn't enough room for "draw". However, same concept using a terra cotta bowl, *partially* filled with concrete allows room for the water to flow - and it will work. However, *some* kind of cover has to be placed over the open hole or it won't pull from the bottom. Is that what you meant, or did I misinterpret?

I installed the plumbing, the liner, and filled the pond. I have the diffuser parts, I just never built it and installed it. I know, naughty, naughty. But with that big hole in the ground...I had to get it full...I didn't yet have my diffuser designed and didn't want to wait. So this year, I'll just have to do some swimming. -- BV. www.iheartmypond.com |

I'm pretty Neurotic ;) but the thought of swimming in a Koi Pond (if I had one) sounds absolutely delicious :) -- **So long, and thanks for all the fish!** |

Alternatively, if you're using one of the retro-fit drains that sits on TOP
of the liner instead of through it, it will be powered by a pump, so a 2" drain can be used. I use one of these drains, and it uses gravity feed to the filter, not powered by the pump, and I've seen thru the liner one's powered by a pump. So I'd say it's the designer, not the drain type that configures the situation. ;o) ~ jan ~ jan (Do you know where your water quality is?) |
