I have a Rena XP3 for about 6-8 months now. I noticed the outlet pressure dropping recently. I took apart the filter cleaned all the tubing no obstruction and re assembled. Same problem-no pressure. I ran the pump for 20-30 seconds with no water--impeller spins but rattles a bit.
I notice my PVC CO2
diffuser only fills 3/4 with water. Water is trickling into the Difuser from the outflow of the Rena but with no force. New impeller? What would make a 6-8month old impeller weak? Maybe the electro magnet is shot?
Any suggestions are appreciated.
