I am in year 3 of our pool, and have finally run into something I just can't figure out. I have a Jandy 2-speed pump with an inline secondary filter basket, chlorinator, and cartridge filter setup. For the past month, my pump loses prime on every start-up and I have to pull the lids off both filters and close them back down and eventually it will pull enough suction to get the water to the pump. Before, I have never had this problem and the pump basket was always kept full of water when idle and the pump started right up.
I have lubed all o-rings, can't find where any air is getting in, and there is no water evidence of a seal leak. I am also not losing more than the usual amount of level in the pool, so it is very unlikely I have an underground leak.
Are there any more troubleshooting things I can try before I pay someone (NOOOOO!) to come take a look at it? Any help is appreciated!
