I have a Hayward C1200 cartridge filter with a AO Smith USQ 1102 motor married to a Sta-rite Dynaglass pump. Yesterday I replaced the old filter cartridge which had an operational pressure of about 30 psi after deep cleaning. Before draining the Hayward I closed the skimmer valve (the only one opened) and closed the inline chlorinator. After replacing the filter I turned the pump on then walked away for about 1 minute when I realized I hadn't reopened the skimmer valve. I did that immediately and got water flowing. It took longer than usual for the air to bleed out of the relief valve on the Hayward. Also, the pump motor is a little louder and rougher sounding than normal. The operational pressure is now about 3 psi. In addition to the increased noise I've been going out about every 15 minutes and bleeding more air out; it just keeps building up. The motor is less than a year old and the seals were just replaced last week (a small rock destroyed the impeller and seals). After the seal/impeller replacement the motor was pretty quiet. I'm guessing the noisy motor and increased air build up is a result of running the pump dry for a minute. Is this anything I should be concerned about? Why would it continuously build up more air in the Hayward? Any advise greatly appreciated. Tim

Thanks for the tip, PC! It actually required a 1/2 open end wrench and some elbow grease and that worked fine! Tim

Hi all, I have an AO Smith USQ 1102 model pump motor. It's about 6 months old. The impeller is a yellow hard plastic type that has broken apart from it's axle nut. I'm trying to get the axle nut off the put on new seals and impeller but can't keep it from turning the whole axle. At the opposite end of the motor where the electrical connections are located is the other end of the axle. It terminates with a screw head surrounded by a metal plate with two springs on either side. I can't get a good screwdriver grip on the screw because of that metal plate. Is there some way I can remove that plate? Or is there a different method I should use to keep the axle from rotating as I try to take off the impeller nut? I'll try and post a pic of what it looks like but if anyone has info please reply. Thanks! Tim
