DAB E.SYBOX MINI 3 VFD Pump

E.SYBOX mini 3 uses the most advanced DAB technologies to create constant pressure according to the system demands and thus an optimization of energy consumption. The new 3-rotor model ensures further noise reduction and energy consumption. Managing the water pressure in your home has never been so simple and quiet. E.SYBOX MINI 3 is the DAB compact automatic booster system for the water supply of a single dwelling. E.SYBOX mini 3 offers the comfort of constant pressure (Pressure Set Point adjustable from 15 up to 79 psi) inside the system. Suitable for use with drinking water, in domestic systems, and in gardening applications. E.SYBOX mini 3 does not require any additional components for its installation.

Is this pump supposed to run (like there was a call for water) occasionally even when there is no call for water ANYWHERE in the house? This is the 3rd dab easybox I’ve had and the first “3” model and they’ve ALL done this.

Hey how are you.. how do u increase the KW

Hi, I have at home Dab Easybox mini 3, every time when starts, a powerfull sound can be heard. Also start almost every minute. Can you advice me please? Thanks

[@rainwaterequipmentllc7835]

Is the pump boosting city water pressure, or is the inlet of the pump being flooded with water from an above ground storage tank?

[@User_2051]

@@rainwaterequipmentllc7835I’m having the same issue, city water in this case.

[@wally6193]

So is the pump still working okay after a year of service? I'm curious about the reliability of these all in one units over a typical submersible with a pressure tank or the ole jet pump system(which are generally noisy I know).

[@rainwaterequipmentllc7835]

Yes, it's still in service, and we've had no issues with it. The MINI 3 has become one of the most popular, if not the most popular, pumps we carry. We've sold a few hundred of them.

It's been 2 years since your video. How is the pump doing these days? Is it more durable and reliable than the scala2 pump from Grundfos?

[@rainwaterequipmentllc7835]

We are still using that same pump in that same location. We’ve had no issues with it and have been very happy with the performance. The Scala 2 pump from Grundfos has been improved, and it is performing much better than in years past.

[@stevewee]

@@rainwaterequipmentllc7835 Scala2 should be improved because it's a very good pump if not for its shortcomings. I will also consider the Esybox mini 3 based on your review and assessment. Thanks.

[@lookin4ward1]

Do you install a pressure vessel on this?

[@rainwaterequipmentllc7835]

It's not required (there is a small one built in), but it's ok to add one if you wish. They can be beneficial to help with thermal expansion when older hot water heaters are in use. They can also be useful in applications where your system is calling for small amounts of water over and over again many times making the pump turn on/off, on/off, on/off, like with a swimming pool auto-refill system or a drip irrigation system as examples. The rule of thumb is to set the pressure on the expansion tank at about 15 PSI below the pressure set point on the pump.

[@corym2695]

What does that angled bit on the intake do? I've been seeing them a lot lately

[@rainwaterequipmentllc7835]

I have the same question. does anyone know?

[@tennesseeboi_8754]

How high of pressure can it maintain, I need a constant 75 lbs, no less, can this pump do it.

[@rainwaterequipmentllc7835]

Yes, the pump can be set at 75 PSI, but it can only produce that much constant pressure up to 6 GPM according to the performance curve shown on the product page. rainwaterequipment.com/esybox-mini-3-on-demand-constant-pressure-pump/

[@daltonsalaskanadventures7673]

What about when the demand for water happens and pump isn’t kicking on right away can take hours or minutes to notice draw and kick on and is lack of water pressure yet pump reading proper pressure on screen no trouble codes, need help 🙏🏻

[@rainwaterequipmentllc7835]

At first pass, I'd guess you had something obstructing the suction to the pump. And you might check to make sure there's nothing stuck in either the suction side check valve or the discharge check valve (aka, non-return or shutter valve) of the pump. We always recommend a pre-filter to prevent debris from entering the pump.

[@daltonsalaskanadventures7673]

@@rainwaterequipmentllc7835 it is a holding tank with filtered water, so on the discharge end there is a valve? Is that inside unit?

[@rainwaterequipmentllc7835]

​@@daltonsalaskanadventures7673 Yes. It's inside the front cover to the left of the digital screen. Kill the power to the pump, and close the ball valve on the water tank that feeds the pump. Open a valve on the discharge side of the pump to alleviate the pressure. Use the small Allen wrench found inside the lid on top to open the green cover on the front of the pump. Then use a set of needle-nose pliers to grab the check valve, and turn it counter-clockwise while pulling toward you. It should come out so you can see if there's anything obstructing it. Don't mess with the rubber cap inside the cover. It's the valve stem cover for the internal pressure tank.

You would only need a check valve or foot valve if you are lifting water from a cistern or tank positioned below the pump.

I have a grunfos MQ3-45 that's been going strong for 8 years now. Researching the scala2 vs the DAB mini box 3, what's your opinion on these 2 pumps?

[@rainwaterequipmentllc7835]

DAB MINI 3 is the way to go. The MINI is a variable speed, constant pressure pump that allows you to control the pressure at the push of a button. It can be installed vertically or horizontally, is dual voltage (115/230V), has a frost prevention feature, and now comes with stainless steel union connection fittings. As of my response on 8/20/22, the SCALA 2 has long lead times. The SCALA 1 3-45 and 5-55 are single speed pumps that are in stock and are very similar the functionality of the MQ, albeit with Bluetooth capability and some cool features that you get when you install the free GrundfosGO app. SCALA2 is not Bluetooth enabled, and the app doesn't work with it. Note that if you purchase from us, we handle any warranty issues on all of our pumps with the manufacturer on your behalf. Other sites/companies don't necessarily do that. Thanks!

[@ntme9]

@@rainwaterequipmentllc7835 How many years can I expect to get out of the dab 3? Say.. 3 people, 2500sqft home. On RWC only.

[@rainwaterequipmentllc7835]

​@@ntme9 That's always a tough question to answer, because some applications use the pump more often than others, and some don't pre-filter like they should. DAB warranties all of its pumps for 2 years, and the MINI has only been around for 3-4 years in the U.S. I believe. But due to the nature of its design, including soft start and VFD (motor speed up/slow down) capabilities, I would imagine if you use a pre-filter to keep debris out of the impellers and you keep an eye on it to make sure there are no leaks in your piping (which causes pump cycling), you should expect 8-10 years of use, maybe more. A small (2-4 gallon) expansion tank is not required but would limit the number of pump starts/stops over the years and might extend its life a bit.

Do you think this could replace my 3/4 hp shallow well pump in my basement?

[@rainwaterequipmentllc7835]

Possibly. It does offer up to 26' of suction lift, but a shallow well jet pump typically has more lift capability, so it would depend on the flow and pressure that your pump is producing and how many vertical feet the jet pump is having to lift the water before pushing it.

[@AG-xf2er]

@@rainwaterequipmentllc7835 thank you for the response. Thankfully the pumps source of water is from above as our small community has a water tower that produces 30 psi without the pump on. In the current setup it is being used as a booster to produce enough pressure to water my lawn with underground irrigation pop up sprinklers.
