Just opened the ingrouind 32X16 retangular with Hayward 3600 Hayward 3/4 h.p. motor which is about 15 years old. Pump motor is running, however it is barely moving water. Not sure what to address....impeller?, seal?, ect.
The filter couplings all seem to be fine, and the filter itself seems to be sealed, but there seems to be a lot of air still bound in the system. Please advise.
