I'm not following what you're saying. If it leaks on the suction side, you probably need to disconnect it and rewrap the the threads with fresh thread tape (5-6 wraps). If you're using stainless steel fittings, you need to use tape made for stainless steel threads, or they will leak. Again, wrap SS thread tape 5-6 times.

@@rainwaterequipmentllc7835 Thank you very much for your insight I appreciate it

It sounds like the check valve isn't sealing properly. Please use this video as a guide to check the valve for debris.

Ill give that a go and thanks so much for your prompt reply!​@@rainwaterequipmentllc7835

I don’t know of any of our clients who have done that with this pump, but they have used smaller versions of the ESYLINE pumps to lift water. While it does have the ability to lift a maximum of 26 feet, I don’t ever like to test the limits of a pump’s lifting capability. It’s my understanding that it will significantly reduce the flow rate if it must lift the water before pushing it.

No.

Depending on what part of the country the tank is in, there may only be a few inches of ice that forms in the top of the tank during sub freezing temperatures over several days. It typically would require temperatures to be in the 20s for many days before ice would begin to form on a tank of this size. Then, of course, as temperatures increase, the ice will melt leaving the tank without damage. Tanks in colder climates may be equipped with insulated board between the liner and the steel walls to mitigate freezing.

Yes to both questions, although the CMBE 1-44 may have a long lead time. The DAB ESYBOX MINI 3 would likely be a better option if you need something right away. rainwaterequipment.com/esybox-mini-3-on-demand-constant-pressure-pump/

Sorry, but we don't handle the DAB swimming pool pumps. You'll want to contact a nearby dealer for assistance. And since you mentioned "cubic meters per hour", I'll assume you aren't in North America. Start your search here: www.dabpumps.com/en

If it’s been working fine, I probably wouldn’t change it now, but yes, you were supposed to change the configuration for the city water pressure coming in.

@@rainwaterequipmentllc7835 yes. It’s been working perfectly for 5 years. The location my cabin is in and the way the water is ran we basically had zero pressure. It would barely pour out of the faucets. I could pee a bigger stream lol. I never even messed with the settings. I unboxed it. Hooked it up. Plugged it up and forgot about it. What about that plug on the back with oil can logo? I just noticed it the other day is why I started doing searches on it now. I’m happy to see all the positive stuff about this pump tho. I did zero research and honestly had very low expectations Are you suppose to add oil or change it at all? It’s a black plug on the very back bottom corner

well that sucks. Is the thread NPT?

Yes. 1" NPT@@vo2098

The DTRON 2 and 3 are not "constant pressure" pumps. But they are "on demand" pumps. If you need a submersible pump that is also "constant pressure", I suppose you could use the DAB ESYBOX Diver, but for an evaporative cooler, you should probably use an expansion tank between the pump and the cooler to act as a buffer. 1st time we have ever been asked this question.

@@rainwaterequipmentllc7835 thank you for answering

We are not well water experts when it comes to iron in the water, but we can say with some amount of confidence that the iron will make its way into the pump and may shorten the life of any pump over time by weakening the seals and potentially causing the pump to leak at some point. Depending on the level of the iron in the water, it may have an impact on the performance of the pump, but whether this occurs in 6 months, 10 years, or longer is difficult for to say. That being said, people use these pumps in well water applications all the time with success, but we couldn't say with any amount of certainly what the level of iron content is in these users' well water applications. Sorry we couldn't be of any real help in this area. Try searching online for competent sources on this specific topic. You're sure to find some relevant and helpful content. Good luck!

It depends on the flow rate that you’re wanting. For 8 - 10 GPM, we recommend this constant pressure, variable speed pump. It allows you to set the PSI where you want it. And it will run off of 115V or 230V. rainwaterequipment.com/esybox-mini-3-on-demand-constant-pressure-pump/ For 15 to 20 GPM, we recommend this 230V one. rainwaterequipment.com/dab-esybox-electronic-water-pressure-system/

No. Sorry.

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

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.

@@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.

The overflow is shown on the top/left of the tank in the video. The tank includes a 1 inch outlet that feeds a booster pump that is not shown in this particular video.

No. CMBE 5-62 is not offered as a Twin.

The only way to alter the flow rate is to partially close a shut-off valve on the discharge/outlet of the pump to restrict the flow. And you can set the pressure on the pump pretty much anywhere you like. Just select a PSI between 15-30, and set. Hold down the Mode and Set buttons simultaneously for about 3 secondsn until the PSI level begins to flash, and use the up/down arrows to increase/decrease the PSI. Then press the Set button.

We almost never get snow in Texas. But the heavy rain events will fill it surprisingly quickly when collecting from a roof of substantial size. The multiplier is .62 for every square foot of roof space. For example, 1,000 sqft will yield approx. 620 gallons of water in a 1" rain event. This building is 9,000 sqft. So a 1" rain will produce approx. 5,580 gallons of collection.

It depends on the amount of roof space from which you are collecting. The multiplier is .62 . You multiply .62 x # of square feet being collected. For example, in a 1" rain event, you can collect 620 gallons of water from 1000 sqft of roof. 1000 x .62 = 620. This 500 gallon tank frequently overflows when it rains.

We can customize the length for you when you order. Just choose the length you prefer, and if you need something shorter than 6' please indicate the preferred length in your order notes: rainwaterequipment.com/search.php?search_query=floating You can do it yourself, but it's incredibly difficult to remove the barb that goes inside the hose after it has been fabricated. It would essentially need to be cut out, the hose shortened, then the barb re-installed in the hose. Not an easy task.

Sorry, but this video is for the CU301. We don’t have experience with connecting floats to the CU300.

Do you have a shut off valve installed right after the pump? If not, you should. If so, close the valve, and allow the pump to deadhead the water against a closed valve. If the pump shuts off, there's nothing wrong wit the pump. And you either have a leak downstream in your pipe somewhere, or a leaking or running toilet, etc. If not, then yes, try inspecting the check valve (like in the video) for debris.

I have the same problem, I will try to inspect as you said. I will turn back with answer. Thank you!@@rainwaterequipmentllc7835

Yes, it should be fine. Let it dry out completely as you have indicated before sending power to the lamp.

If you are lifting water from below the pump, you will likely need to install a foot valve on the bottom of the suction pipe down in the "water hole" to prevent the water from going back the opposite direction. Once you have it installed, start filling the pump with water, which will also fill the suction piping that goes down to the foot valve where it will stop. Once the pipe and pump are full of water, the pump should be able to prime.

​ the thing is there is already a foot valve in the waterhole on the suction line. Doesn't the pump have an integrated foot valve ? So if I fill the pump, it will just fill the internal reservoir and not go into the line up to the water hole?

Yes, you can use an ESYBOX Mini 3 as the pump to pressurize the water in your 1500 gallon tank to send to the point of use. We recommend installing the pump close to the outlet of the water tank.

Hold down the “mode” and “set” buttons simultaneously for about 3 seconds. When PSI begins to flash, use the up or down arrows to select the desired pressure, and press “set” button. That’s it.

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.

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

​@@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.

@@rainwaterequipmentllc7835 will I need to re prime unit after doing this? And what psi should the air bladder be at for 48-50 psi water pressure

No, sorry. They come in black, dark green, dark brown and mocha only.

Yes. You would simply need a T or Y in the suction pipe that feeds the pump with an isolation shut-off valve on each supply, so you can manually open/close one at a time as needed. Be sure to use a pre-pump filter between the rainwater tank and the pump to prevent debris from entering the pump. City code may require a back flow prevention device (like an RPZ) to be installed in order to prevent the rainwater from commingling with the city water.

@@rainwaterequipmentllc7835 Thank you!

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/

Of course. Thanks Scott!

Since this pump is dual voltage 115/230V... 9.6 Amps at 115V 4.8 Amps at 220V They are very energy efficient due to the soft start feature and the fact that the motor speeds up/down based on use.

In this situation (if you want to wall mount it), don't change the position of the shutter valve. It really only needs to be changed if your inbound flooded pressure is around 35 PSI or higher (I found this out after posting the video), but it won't hurt the pump if you do change it in low pressure, flooded suction scenarios. Be sure to install a check valve at the ball valve of the water tank to keep the pump primed and water from going the other direction, especially if you mount the pump on the wall.

@@rainwaterequipmentllc7835 this is an awesome and super useful answer! Thanks so so much!
