Based on responses from other posters, I guess I may be alone in thinking
that Scooby is describing an *indoor* water feature -- if so, wind would
presumably not factor into things, but what happens if there is a disruption
in your water source? I have visions of the house burning down when all
those pumps get overheated!

Good point. I definately haven't thought of that. Is the wind really
that powerful that it can blow a huge, heavy stream of water by an
entire foot or more? If so, would this piece of art work on calm days
under close supervision (i.e. whenever I am out in the yard doing
yardwork, entertaining guests on a calm day with no wind, etc.)? or
would a tiny little gust of wind throw it all out of the pond?

I guess what I'm asking is how many miles per hour does the wind have
to be blowing in order for it to be strong enough to blow the jet foam
streams of water over a foot or two of distance which would be out of
the pond?

I'm not sure about how many gallons of water would be in the air at
any given time either. I would have to calculate that somehow but I
don't know how. It's starting to sound like I might have to limit
myself to only 1 or 2 of the foam jet fountains in a little 5x4 foot
pond, even then though, the wind may become my worst enemy until I can
build a bigger pond.

What if I just had 1 foam jet in the center of the pond? Would that
work on a windy day? If not, what is the smallest pond I could
purchase that could handle the wind problem? If I went with only 1
jet, the wind could blow the foam jet stream 2 feet in 2 directions
and 2.5 feet in the other two directions before the water would leave
the pond I guess, which leads me to my last question. Say a big 35
mile per hour gust of wind comes by. About how far does it normally
blow a 3 or 4 foot high foam jet stream? 2 feet? 4 feet? 6? Anyone
ever measure? I'm hoping my project isn't going to become a
catastrophe because of this wind issue (Damn Mother Nature!).

when wind gets 10 mph it starts drifting the water colums on my TT's to
where most of the water falls to the side so thats about 18 -24 inches
here we get 20-30 mph winds quite often those push the taller column
(the 2ft one) 10-12 ft to the side

mind you I am out in the open no buildings around at all in a city i
think it wouldnt happen too often

Pardon the pun, but I think we have a pipe dream here.
Simple math ..... three 3000gph pumps ...... less than 100 gal. of
water .... that's one complete turnover every 30 seconds.
Simple hydraulics ..... Too much turbulence. Pumps would cavitate.
Water could not return to the pumps fast enough.
Have you ever watered your lawn or washed your car on a windy day? You
get as wet as the car.
Like the song says "Don't tug on superman's cape or spit into the
wind!"
Try using a garden hose to simulate the effect you want. I think you
will find it much less than 3000gph. (IMO)
Time your garden hose into a 5 gal. bucket ......... See how far you
get in 30 sec.

In reading your questions and the responses, I would suggest solving the
wind problem first. Check with local weather stations / forecasters /
online to determine range of wind speeds. Limit wind variables by
screening, walls, location, location, location, of your water feature.
Limit wind variables by using fountain only when supervised. Connect
water feature to wind sensor to shut off if wind speed exceeds a
specific point. Then design your water feature with whatever pump /
basin / amount of water will work for your area / location. Sounds like
a fun project -- keep us posted.

Thanks. That gives me something to start with. What a difference an extra 15
MPH wind gust makes!
And that's only a 2 foot column? I'm hoping for 3 to 5 foot lighter foam
jets. Hmm. Hope that high wind sensor shutoff unit has a quick response
time.

Thanks for the info. I can't wait to start experimenting. I live in a rural
area with high winds so a unit similar to the one above will be a necessity
for this to work.

Don't get me wrong? I like the idea. Especially at night with the
right lighting, but (here I go being negative again) IMO I think that
the surface area of that pond is too small and that 100 gal. is not
enough water to achieve the effect you are looking for. The water
needs a larger surface area to return or you will end up with a
high-tech very costly lawn sprinkler.
I really am interested in how this turns out, but, but, but, but,
but, (Just my nature I guess)

I'm thinking it is going to be very very close to very very very very close
if it works. I always have the option to upgrade the pond size as the final
tweak but I want to save that option as the last resort option.

If it works and looks good under the right conditions in such a tiny pond,
it will definately make me want to upgrade the size of the pond sooner than
later but after digging 100 gallons of hard clay and dirt all last weekend
with a Garden Claw and a shovel by myself when it was 90 degrees outside, I
don't want to touch another shovel for a while (didn't seem right to rent a
small Bobcat or excavator device for what at the time seemed like a puny 100
gallons) and I haven't looked into how much it would cost to hire someone to
dig out another 100 to 200 gallons of earth (if anyone knows the cost,
please tell me), plus, I want to see if I can defy the odds by getting it
not only to fit in the tiny pond I have selected, but to have it look really
nice as well. Plus, this particular pond has the perfect shape for the area
I have selected in the yard (considering there aren't very many good designs
for preformed ponds - in my opinion).

I don't want it to look overcrowded either though, but since I have mastered
the art of making small rooms inside the house look huge, I should be able
to mask the fact that this pond is tiny and still have it all look perfect.

When you mention that the surface area of the pond is too small, what
exactly do you mean? Do you mean that with slight winds, the jets would blow
the water the couple feet out of the pond or that the jets require a larger
surface to land the water safely under calm to zero wind conditions?

The reason I ask is because besides the looks, the other reason I'm going
with the foam jets is because they have very small diameters when they come
down (compared to other fountains like the 3 tier sprinkles, etc.) The
diameter of space the jets need is very very small.

I'll just have to wait and see how it turns out I guess. Who knows. In 1
week I could be digging again, but I hope not...

I live in a clay area. Try wetting the ground really well and then
letting it sit and soak in for a while before digging. It's heavier
this way but a lot easier to dig.

The ground I live on is a form of clay known in the scientific community as
"Groundis as hardis cementis". I found the best way to dig for me, was to
use a pick axe or hand pick, and just hack a trench as wide as the tool. Let
the tool do the work. Then I would use a shovel to chip off the sides of the
trench, letting it fall into the trench. I'd then scoop out the loose pieces
of concrete...I mean clay. Lather, rinse repeat. Just keep expanding the
trench. Work in layers, getting wider each time.

Damn...ya know...I was going to take pictures of this when I discovered how
well the technique worked, but figured I would get laughed at.

From years of watching construction workers, I'd venture a guess that
you don't have a beer belly that overhangs the hammer, which seems to be
a requirement for proper operation.

Holy ****balls. Creating a pond is a lot of work. I thought of another
device I could use though. Besides a wind detector like this one:

http://www.smarthome.com/7196.html

I could also use a water level safety shutoff device. Anyone ever use any
before? It would just have to be able to turn off a normal AC switch when
the water level reaches a low level in the pond. That way, even if the water
does blow out of the pond during high winds, the pumps would be
automatically shut off so they don't get burned out.

What about trenching electrical? Anything to it that I need to know? I'm
guessing I should just trench a thicker guage extension cord to the pond
(about 20 to 30 foot cord), that way when I want to upgrade or replace old
pumps, I don't have to dig out the pump/light cord(s), which I was surprised
to find is not detachable from most of the pumps I have looked at.

My goal is to have 2 or 3 pumps plus lights attached to an extension cord
that goes to the outside house electrical jack which has a ground fault
interupter. I feel like I'm missing something though. What should I use to
waterproof the area where the pumps connect to the extension cord? Just wrap
them in plastic and seal with duct tape or something? Seems like there
should be a better way.

There is a much better way.... call an electrician! I can
see you are a quick fixer ;-) ... not good to hook up your pond
with nothing but extension cords. And Please
don't wrap the cords with plastic. It holds in heat and could
easily cause a fire. If you must use extenesion cords buy
some dielectric grease from an auto parts store. Smear that
all over the ends. It is water proof.

I would like to see you post that you've thought about it ..
and your going to hire an electrician.

I think I would call in an electrician who does this sort of
outdoor application to at least get an estimate.
They will let you know what you can
and perhaps should not do. I have no idea on fees.... they
are pretty much dictated by the union ... (I think??)

$400 just for the electrical help? That seems rather high. I only have to
trench about 20 to 30 feet. I watched a neighbor trench his cable line in
about an hour and it didn't seem that involved. Did you have a lot of other
electrical done at the same time or something?

Speaking of shut-off devices based on water levels, do the pumps that have
shutoff capabilities work very well? Or is it always better to use a
separate shut-off device and not rely on the pumps with built in shut-off
capabilities (especially when running multiple pumps in an array)? I guess
what I mean is this: By the time the low water level activates the shut-off
mechanism on the pump, is the pump already slightly (even very slightly)
damaged in any way or is it just a normal proven method for shutting off a
pump that has no side-effects whatsoever (or shorten lifespan of pump in any
way)? (I keep hearing horror stories of people who let their pumps run dry).

The reason I ask is because my pond will be teensy with wind blowing the
fountains spray out of the pond on a constant basis (unless or even if I use
a wind detection shut-off device with this setup) and the water level could
reach shut-off levels on a daily or at least weekly basis (grass should be
okay because it's all down hill or in a rocky area with good drainage).

Is it kinda like with a PC? You could use an average powerstrip for your PC,
or you could do the right thing and use a UPS that not only protects against
electrical spikes but also has a battery backup to prevent your PC from
shutting down hard in case the electricity goes out.

I'm all for redundancy, but to a point. I would not run any PC without a UPS
so I'm guessing I shouldn't just rely on the built in shutoff mechanisms
built into certain pumps, but, as I'm slowly finding out, ponds and all the
electrical devices that go with them (pumps, underwater lights, wind/water
level shutoff devices, etc), are very far from the PC realm.

Hopefully this week I should have some pictures of this crazy super pond
project from heaven (I can hardly wait to hear the laughter of my attempts
to get 3 pumps with fountain jets in this small 4x5 foot pond), but I must
complete the project, even though it is going much slower than I had
originally anticipated and has cost me a few extra dollars than I had
accounted for. Hopefully it will be worth it in the long run.

Once again, thanks for all the help. It has been not only fun but amusing as
well.

hmm I wouldn't know.

I'm sure It adds to their ????? you pay them.

but I don't think he wants to do digging!!! if 'I were an electrician I'd
only want to do the hookups.

Almost assuredly. You may be able to save by doing the digging
yourself. A pro may have a vibratory plow, which can put the cable in
with out digging.

The GFCI should go at the house part, so that this way, your protected
if the cable is hit or breached, it will trip.

There is special cable that is rated for burial underground, to handle
both the heat, and soil exposure, moisture, and bugs.

You may also want to put in a post or something else to attach the
remote box to, if you want something other than a plain pipe, like a
wood post.

Nedra is right use an electrician and do it to code
my 1cents worth if you bury the extension cord and somehow a fire
startss your insuranc may not pay somtheing to consider
I have seen that happen when I was a firefighter

Not just the help. The conduit, the wiring, the post, the box, the burying,
contacting city, the permit, the inspection.
It is all what your market charges.
My husband is an electrical engineer and wanted someone who knows city codes,
etc. (He can build you a safe nuclear reactor but he relys on electricans for
work on our home.)

The reason why I suggest this is you sounded a little wonky on the whole
electrical business. Don't want to fool around with electricity if you don't
have a clear understanding of it. With as many children, now teenagers, around
our yard we felt that safety was our highest concern and cost wasn't an issue
when you consider the consequences. I was the before and after-school care mom
on our block so we're talking a lot of kids ;-)

The pumps that I have seen with auto shutoff devices are all sump pumps.
They have the switch to turn them on automatically when the water in the
sump comes up to a point, and cut off when it goes back down. Those pumps
are not rated for continuous operation, and most of them are real energy
hogs. You can buy the parts for a switch, a piece of threaded rod, a few
nuts and a toilet bowl float.

I have both systems. One on the pump built-in is probably best for you, so
you don't have the large bobber in the water.... though as an artist you
could probably disguise it to look like a boat or glue some fake silk
aquarium plants to it. One on the pump will let your water go lower, the
bobber can be set so it turns off at a point you prefer. Either way, both
work. I got my mercury float switch from www.aquaticeco.com ~ jan
