What are the flow rates for the Zakki Sieve?
The 16" Zakki Sieve has a maximum flow rate of 4500 GPH and work best with more than 1500 GPH.
The 24" Zakki Sieve has a maximum flow rate of 9000 GPH and work best with more than 4000 GPH.
How many inlets can be welded onto the sieve?
The 16" Zakki Sieve can have a single 3" or 4" inlet pipe, but if 2" pipe is desired then you can have up to three 2" inlets.
The 24" Zakki Sieve can have up to three 3" or 4" inlet pipes, but if 2" pipe is used on some of the inlets then you can have up to five inlets.
Can the Zakki Sieve be installed BELOW pond water level?
Yes and no... The lowest elevation that the Zakki Sieve can be installed is so that the BOTTOM of the sieve is 27" below pond water level. That leaves 7" of the filter above pond water level.
Can the Zakki Sieve be installed ABOVE pond water level?
Yes. That is exactly what the filter was invented for. You can install the Zakki Sieve as high above pond water level as you need. Keep in mind though the higher it is installed, the stronger the water pump you will need to flow the same amount of water.
What are the dimensions of the Zakki Sieve?
The large Zakki Sieve is 24" in diameter and the small Zakki Sieve is 16" in diameter. Both sizes are roughly 34" tall including the domed lid. In order to open the draw latches on the lid properly you will need to have at least a 4" air space all the way around the filter. You also want to have at least 10" or air space on top of the filter so you can easily remove the lid and sieve screen from above.
What is the Zakki Sieve made out of?
The body and internals of the filter are PVC, the 250 microns sieve screen and the draw latches are 316 stainless steel, the o-ring seal is EPDM rubber, and the domed lid is acrylic.
What is included with the Zakki Sieve?
There will be a union provided for each pipe that is welded onto the filter. You will also receive two 2" Pentair 3-way valves so you can incorporate the bypass plumbing and pump assisted cleaning circuit on the filter. All other valves and fittings are up to the customer to purchase.
How is the filter shipped?
In order to protect the filter from damage they have to be strapped to a pallet and shipped via truck freight. Even though this is the safest shipping option sometimes damage still occurs. It is your responsibility to inspect the filter for damage BEFORE signing any paperwork from the freight company. If you see damage, take a picture of it and note the damage on the paperwork. Unfortunately the website cannot calculate freight charges at the time of purchase, so a second freight payment will be required before your filter can ship. This is the only option for shipping the Zakki Sieve, unless you want to schedule a time to pick it up personally.
Can I connect a bottom drain and skimmer together into the sieve?
Yes, you can connect them together if necessary. Each suction point should have its own true union ball valve so you can control the water flow through each pipe, as well as a true union swing check valve to prevent water from back flowing into the pond when the water flow is stopped.
How is the sieve screen cleaned?
The easiest way to clean the screen is to install the included 3-way valves into the plumbing so you can use the water pump to flush off the screen. More information on this process can be found by clicking the "Find Out More" button below. If you want to keep your plumbing more simple, then you can eliminate the 3-way valves and turn off the water pump, remove the domed lid and use a hose to wash the waste out of the filter.

Can I install the Zakki Sieve in direct sunlight?
Yes, but you need to make sure that there is water flowing inside the filter to protect it from over heating. The domed lid acts like a magnifying glass and if there is no water flowing through the filter to keep it cool, then the inside temperature can spike very quickly and cause the plastic to distort inside the filter. The greatest risk for damage is before installation. If you need to keep the filter out in the sun, then remove the domed lid so the inside can be cooled by the ambient air temperature.
How do I remove and install the sieve screen?
In some cases the screen fits more snugly than others, so the removal and install process is a little bit more tricky, but over time you will get the hang of it. I created this video to show you the proper screen fitment.

I've seen different types of valves for your setup, 3-way, or knife-valves.What comes with the unit?
All systems come with 3-way valves and standard ball valves. The knife valves were only used for prototype models to save money.
Waterflow > 90gpm. Will this not suck all the air out of the unit like on my existing priming pot?
That is a big difference in flow, but the resulting water levels inside the filter would remain the same. The waste trough would just get splashed on more than it should due to the higher flow rate.
Is the v-screen easily removable in the event I have to hose off debris?
Yes it slides right out, and as with all sieve screens it does require periodic maintenance with a hose.
Can I take off the cover and hose the debris out through the cleanout port without cleaningline?
Yes this is possible, but it would be an inconvenience for you to drag out the house each time.
Is it possible to get the unit painted flat black?
You are more than welcome to paint the unit black, but it will be shipped white.
What are the dimensions for the sieve models?
16" 4500 GPH , and 24" 9500GPH. About 3' tall
How far would you locate your sieve away from the pond ?
There is no specific distance that is too far, but obviously closer is better. The further away the sieve is the greater the dynamic head losses so the larger the pump needs to be. Personally I wouldn't go further than 30'
Have you seen multiple small drains hooked up to one Zakki Sieve ??
I haven't seen a bunch of little drains but I have seen skimmer and bottom drains together on a single sieve. Just make sure that each suction line has a ball valve so they can be shut-off individually.
