About the time we received our new pump, the old one quit squeeling. Not sure why..unless I finally backwashed enough.
Now I'm torn...
The water is circulating very well..strong suction/strong return. Not sure about the pressure as I've got a new gauge but have not replaced it yet. While the old one is quieter now, it still has infrequent periods of loud grinding noises and then returns to normal sound.
I am tempted to not replace the motor and pump just yet EXCEPT that I can not seem to get my pool clean. Had major algae upon opening and have now run close to 50 bucks of chlorine through it. Alkalinity was low yesterday but I put 8 lbs in so should be good (waiting on reagents to arrive to test again). I broke down yesterday and put clarifier in it only to get up this morning with dead algae floating on top instead of settled on the bottom.
Is it possible this pump/motor is not working effectively at all times...maybe hanging at times causing poor circulation? I've watched and watched and have not noticed a flow decrease, but I can not figure out any other reason that I have been unable to clear the algae. I've kept it at shock level for close to a week and other than the alkalinity, all other numbers are good (well, am adding CYA now).
Would you replace or stick the new one in the basement as a back up?
