Dear Compositerpro, i am not sure from water pressure after the backwash, i think there should be a pressure drop through the filter and then the discharge pressure is minimized.

the issue is for a sand filter for swimming pool, while the main problem is the pump room at basement level and i have a confusion regarding the drain of the filters, shall i discharge to the existing sump pit or to consider the backwash as a forced main and to be elevated to the sewer manhole.

Good Morning All, i have a concern regarding the backwash discharge from water filters, will it be under pressure or not ? i.e. when i am going to design the drain system, shall i consider the backwash as a forced main drain or to be discharged by gravity ?
