Hello, maybe someone can direct me correctly.
I have a Hayward hp21104t heat pump showing P5 error code.
Phone tech advised to run sand filter on recirculate and that took error code away. Filter shows 22psi after backwashing.
Units and pool operated no more than 2 months total. (new pool) install
here are my questions;
what is an ideal psi for filter?
should I change sand in filter? What type and size?
Does heat pump operate on all four speeds of pump?
Thanks, Al
