I recently did a rebed of my Fe filter (https://terrylove.com/forums/index.php?threads/change-fe-filter-to-katalox.81045/) .
Now it has a new problem --- water discharging from the drain line after the unit backwashes and goes back into service. If I relieve the air charge by manually cycling the unit into backwash and then putting it back into service without recharging the air, the leaking stops. So it seems the internal air pressure is causing this somehow.
My immediate thought was to replace the seals and spacers again (as I have done many times, and as recently as February). So last night I replaced the seals/spacers, piston, injector, and injector screen. but it did not make any difference. now I'm stumped.
