This is my first pool and have fixed a number of issues but i want to make sure i have this one right before i go any further.
First off, I have a DE4800 filter and a solar heater.
When i dont have my diverter set to the solar heater, i have no issue. No DE in the pool.
When i have it diverted to the solar heater and my pump shuts off, DE gets pushed back into the pool through the main drain and skimmer.
I have a check valve in between the diverter and the filter and i think this is what has failed but i want to be sure before i replace it.
If it is the diverter, would it hurt it to put it after the diverter going up to the solar heater. It is in a much more accesable location.
Thanks in advance. Below is an image of my setup.
