Brinsea Octagon 20 - humidity pump

Date sort Score sort
OK we have been using the humidity pump for 2 weeks and it works, then STOPS working and just spins and spins and spins!!!!! We replaced ALL the hoses SEVERAL times. It will work perfect for a day or three, then it STOPS working. ***?!!?!?!?!?! I need to call Brinsea first thing Monday. Now that I am in lockdown it really can't hold 60%. I even ordered EXTRA tube when we bought it, and we have all but gone through it all. No way the tube could wear out after a few days. Sigh this IS so frustrating . My hubby thinks the design is TERRIBLE and they could have made this pump so much better. Maybe we just got a dud unit but we have spent HOURS messing with it. So frustrating!!!
 
Called Brinsea, the instructions say the middle tube should be 5 1/2 inches but it really should be tighter at 5 1/4 inches! Good to know, hope I can help someone else out with that information.
 


Totally agree on sucking the water through the tube with your mouth. I tried all solutions, I.e. Changing hoses, checking for obstructions, etc. nothing worked until the sucking trick.

I have been working with mine for a couple of hours. I checked for leaks and I had none. I loosened the hose going into the reservoir so it would reach the bottom, loosened the ones around the gear shaft so it would be a little longer and not flatten the tubes and I raised it higher. I had the bator set at 35% RH and it quickly jumped from 22% up to 48%. I decided to lower the pump because maybe the gravity was working too well. The pump cut off, so I will continue to watch it tonight and tomorrow because I want to start my hatch on Saturday. Maybe I can get the kinks worked out by then. I am not sure the design is so great and the instructions were clearly written by their engineering staff, not normal people. I am not sure that this was $150 well spent.
 


I gave up on my Brincea pump. Never could get it to work and I, too, changed out the tubes. I suggest you " Google " Dry Incubation Method". I have had very good success with this.
 
I want to thank everyone who posted to this thread. I received my humidity pump today so spent the evening setting it up. I incubated 23 eggs, out of the 14 fertile eggs, only 2 hatched and only that is healthy. So I broke down and spent the money for the pump and going to give it another try. After setting it up, even though the instruction said to wait an hour for the humidity to stabilize, it did not after 3 hours. BYC thread came to the rescue. I sucked the air out and voila, it worked within minutes. Boy, you guys are the best, thank you for the tip. You saved me many hours of frustration.
