If a Tecma toilet does not hold water and the black tank is showing almost full...the vent to outside is blocked off and all the water will go down....if vent to outside is blocked, then air can't get in to hold water in toilet even if tank is not full...Check outside vent and make sure unobstructed before going for any toilet parts..and trust me THEY AIN'T CHEAP!....
