Jebao pump OWNERS apply within!

Very true. Besides one member saying his pumps got fried along with his power supply, the power supply is the only issue. One member said he had one surge but was still operating. Have yet to hear back on that one. I theorized it was a faulty........ You guessed it! Power supply. There are others who said that their pumps failed but it was never verified if the pump itself died or the controller or power supply. Bugs me that a sub $20 part is killing this whole line up.

still have not messed with it. I was thinking I tried one from a existing and did not solve the problem it would run for a while then quite.

Also wanted to ask the newer one out now you can not access the impeller correct?

My DCT4000s are very easy to access the impeller. The whole face of the pump just twists off. No hardware. Kind of a tongue and groove set up with a gasket. Not sure of the new 6000, 12000, and 16000 though. I find it very convenient and even have stuck my hand in the sump to see if I can feel any flow leak. It seals up tight.

Just a quick update.

The DCT4000s are still kicking! The PC fan has kept the power supplies cool. It is actually too much fan as it is cooling the sumps as well. Noticed that the tank temps drop a few minutes faster and evaporation rate has gone up. Flow is great. They are whisper quite even at 100%. They do make a funny but normal noise on start up after using "feed" mode.

I cracked open one of the factory included power supplies, and looking at the layout of the components inside it will be easy to modify the case for some ventilation which is all I think these need. There are two big heat sinks inside that run almost the entire length of the box. Some properly placed vents, or some vents and a 40mm $2 case fan tied into the factory board and bam. Problem solved! That will be the next update as the 120mm PC fan gots to go. Lol. Here's some pics for those who don't care to go opening their power supplies just because.

if we wanted to add a fan where would we solder the fan to the factory board?

Dct12000 just arrived. Already have some questions. It came with two barbed adapters that different in diameter from top to bottom instead if seperate sized fittings. Im guess i have to cut them to the size i want ?

My plan is to use the (+) and (-) leads leaving the case and run two 40x40x10mm fans in series. Doing it this way turns two 12vdc fans into one 24vdc fan. Removes the need for any other parts required but the fans and some basic soldering. The amperage draw of the fans I have chosen will have a 0.3 amp draw. I'll post pics when I get it done showing where to drill holes and where to mount the fans.

If you plan to use a smaller hose barb you would just cut off whatever is smaller down the line. I didn't use those at all. Many reviews stating that they leak which makes sense because there is no gasket to make the seal. I went to Menards and spent $4 on 4 fittings. Two thread x thread connectors and two threaded hose barb connections. You then just use teflon tape to close the gaps in the threads and make it leak proof.

Thx Red_Man i dont wanna derail this thread sorry man.
Im gonna just start a thread on the sunp build. But yeah i guess that makes perfect sense. Gonna tag you on the thread

Thanks I have the new 12000 but saw no srews to the housing so assumed you couldn't.

I put about 2' of 11/2" pvc reduced to 1" with a check valve and a spray bar . I was surprised I thought I would have to reduce flow conciderbly but that little bit of 1" pvc really reduces your flow so if you can go all 11/2" that's the way id go.
