Hi Forest,
I replied to your email a minute ago. I think you might want to try priming the pump without anything plugged into the pump. This is something that sometimes needs to be done when the pump has run dry. If the pump doesn't run dry you won't need to do this. Start by unplugging the pump from the RainDome or misting nozzle. Place the tube into the water reservoir or even into your potted plant. Power the pump on and let it run for about 30 seconds. You will get a steady stream of water. Power off the pump and connect the tubing to the RainDome or misting nozzle. Power the system on again and you shouldn't have an issue anymore.
The AquaZamp pumps will self prime if the pump has an operation of a few minutes after it has run dry, but if very short misting or rain times are programmed the pump doesn't get a chance to re-prime itself.
Now that I am down to just one chameleon I am operating as if I were a customer, one RainDome, one pump and a timer. I have run dry, so I know how easy it can be to not refill. Since I run for a minimum of 5 minutes per operation I haven't had to re-prime the pump after running dry.
I am very certain your pump is functioning fine and might just need a good, no back-pressure priming and it will be back to normal operation. I included my cell phone number in your email, so feel free to text or call me tomorrow.
Thanks,
Kevin Zamp
