## Questions & Answers

**Q: How do i get a 20mm replacement nozzle for this pump ?**
A: I have been trying to reach this seller for quite some time now without any success.  I have used the email address on the box as well as tried messaging them here.... no luck

**Q: How do i set this product to be on a steady flow. The manual isn't clear.**
A: If you press the mode button it switches between 3 digit numbers starting with a 1 or a 2. anything starting with 1 is steady flow. If you decide to use wave mode though the number preceded by 1 also affects wave mode. The number preceded by 1  appears to affect duration of the pulse where as the number preceded by 2 affects the time between pulses if the fist number is set to high the pump runs continuously regardless because the cycle doesn't end before the second begins. So long story short if I set the first setting to 101-104 then set the second number to 209-210 my tank really rocks and roles. Timing and duration are key to getting a wave going.

**Q: Can I use this pump externally?**
A: Yes and No.  Mine leaked external.  I had to silicone it by unscrewing it and sealing it completely with silicone.  Now it doesn't leak and is external. Caveat Emptor.  But, so far a great pump.

**Q: Is it submsial?**
A: yes, i have 2 of the 18000 models and they are both submerged ...

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent silent pump
*by  on Reviewed in the United Arab Emirates 18 December 2023*

This is the best pump I have used, it is super silent, I have to check the output to make sure its running, installed it yesterday only, will update incase of anything

### ⭐⭐⭐⭐⭐ Best Pump I have ever bought
*by  on Reviewed in Canada 11 October 2021*

I used this pump for almost a month now, it is so quiet compared with the 2 other pumps I have purchased before, even those 2 other pumps were also advertised they are quiet products.I have a 200-gallon fish tank set up in my living room, the sump pump is below my fish tank inside the cabinet. The environment is really quiet. After I use this DC-4000 pump, I can't even hear the pump is working, all I can hear is the water running.When I first install it, the pump was set to pulse pumping mode, without the user manual, I can not figure out how to change it to the proper setting. Those setting does not make sense by just look at the controller display. After I read the manual and programmed it to the setting I want, it works perfectly.From time to time, I turn off the power to do the water change, the setting will remain after I power it back on.Overall, just need to read the manual, program to the setting you want, then it works perfectly.I totally recommend it to other users.

### ⭐⭐⭐⭐⭐ Odd thread size
*by  on Reviewed in the United States 11 November 2024*

Fantastic pump! Plenty of power and extremely quiet. Time will tell but so far great value. Love the variable speeds and digital display. Have it running submerged in my sump pushes plenty of water straight up 5’ through 1” PVC. 300 gallons per hour on setting 7.Odd thread size though. There’s no fitting out there at your local hardware store that will fit it. Not a problem if you use hose or tubing but I wanted to hard plumb it into my existing system. Had to get creative. Used the large hose barb fitting it came with and glued that into the pipe. Works great.
