    Do I need a check valve?

    I'm installing a heater. I'm going pump to filter to heater back to pool. No chlorinator or anything else. I thought I needed a check valve after the heater but now I'm wondering if that's only for people with chlorinators after the heater.

    Only if there is a chlorinator or if the heater is below the water level in the pool

I think the practices regularly espoused on this forum (especially the BBB method) are outstanding; however my comments will be often oriented towards the goal of getting it done, and getting it done right now!
