Waterway Champion 1HP SF1.65 pump
Hayward 250 Lb Sand filter.
The pool is returning dirt into the pool upon start up for a few seconds. Filter was replaced by warranty company. The problem persists. The spider gasket was replaced about 2 weeks after the new filter was installed. The problem continued. After troubleshooting other potential causes of the dirt returning upon startup, i came back to the spider gasket. It was damaged again. I replaced the spider gasket again last week. This week it is leaking again. I don't know if this adds anything, but water only leaks out of the waste line when the pump is on recirculate mode, it doesn't leak on filter mode. I put it on recirculate mode as a way of checking if the gasket is damaged. If its not it wont leak on filter/recirculate, if it is damaged one of those modes will leak. thanks!
