Hi there.....I signed up here to pick the brains of fellow ponderers.

I have had a 10,000 gallon koi pond for quite a few years now and think I know a little bit about pumps etc but I have a question I am hoping someone can help me with. I have an external pump and bead filter/UV etc but I am on my third submersible pump now for two new gargoyle spitters. I had one cheapy gargoyle hooked to a 500 gph and when it got damaged I got the new ones. They are quite nicer than the old but I am having problems with water flow. I knew the 500gph was way too small so I went up to a 1360 gph but it only produced a dribble out of each. Then I bought a 2400 gph and the water does hit the pond now but not in the way I was hoping/expecting.


I have a 3/4" fitting coming out of the pump running uphill about 3' to 4' vertically and 6 or 7' horizontally to a tee that reduces to 1/2" tubing that corresponds with the gargoyle fittings. I am getting ready to drop a couple more hundred dollars on a Little Giant 5500 that has a 2" outflow so I will have to use creative plumbing but everywhere I have read says that the flow will be reduced and the pump power wasted if I plumb down to 1/2".
I want it to spray halfway across the pond and think the bigger pump should produce the results of a hose sprayer that you can crank down to a forceful hard spray but please tell me if I am way off base here.

If so any ideas to create the spray I desire? Thanks so much for any help with this.

Hello and welcome @April55.

Do you have any pictures you could post?

How deep is your pond?

I have several DIY spitters [1/2" or 3/4" black tubing connected from pumps to PVC arrays]. I have each pump [from Home Depot] enclosed in one of the black pump boxes [the kind that come with 2 sponge filters]. I don't recall the gph of the pumps, as they were all sort of left-overs and are different sizes. I never have a problem with flow, and I only clean the filter pads twice a year. However, my spitters are designed for the water to drop directly back into the pond and I don't expect the water to flow out at with any distance.

I'm sure someone else here can help you. I just hook things up and hope for the best.

Here is a picture of them with the 2400gph pump. I want them to spray across more than half the surface. Thanks for your helpful information.
The pond is 4' deep in the middle with shelves of 2 1/2' and 1'.

Be sure to match, and not exceed, the recommended flow rate (in gpm) for the desired arc length as indicated on the chart shown at the above link.

Yes you'll loose flow rate but it's pressure you need to arc the water across the pond. The mentioned spray nozzles will do what you need. Nice pond by the way, keep the pics coming for us.

Thanks for the help and kind words about my pond. I built it all by myself when I was younger (couldn't do it now!) and I will post pix once I get those gargoyles to really spit!

I see two issues you'll need to deal with.
One is will there be a way to hook up those nozzles to your gargoyles? Generally those spitter things come with their own outlet nozzles built it. Sometimes they may have a "jet" type nozzle, but very often it is simply a straight pipe.
The other issue is the rated head of the pump. Some pumps are designed for max gph flow rate at very low head ratings. The head is basically the outlet pressure rating at which the pump is designed to work which relates to how high it can pump the water. You should be more concerned with the head rating of the pump then the gph flow rate since you'll need good pressure to force the water through a restricted nozzle to get it to shoot a long distance.
With that in mind I don't now if that Little Giant 5500 that has a 2" outflow would be the pump that would work for you. Look at the charts on the link that Meyers posted, you see the flow rates are much lower than 5500 gph (91 gpm), it is the head ratings that are important to obtain the distance through those jet nozzles.

Thank you for all this intellectually challenging (for me) information. I hate to throw money at the problem and end up in the same spot so I will check out the head rate of the pump I have and any I look at to replace it. I am not sure how the nozzles will connect except with forcing tubing over the end of the straight nozzle to continue on to the spitter. I wll have to have one in hand to look at it and my options so I don't want to order a $50 one. Maybe an $8 from Amazon since I can't figure out who might have them locally. Thanks again!

I like laguna pumps most come with a 3 or 4 year warranty and they are energy efficient

There are usually some type of connectors, fittings, or clamps for this. Maybe with this help and the advice you've gotten from KOIPHEN, you'll get it worked out. Be sure to post pictures so we can see the end results and see how well the nozzle suggestion works for you.
