No regulator when I flush. Usually empty tank. Turn on flush for while till kinda clear. Close valve letting more water build up. Open valve while flush still running. Run till water kinda clear. Close valve letting water build up again. Open valve. Continue till water runs clear. This is at full hookup site. Would never take this kinda time at a dump station.
And I am able to hear the water spraying in on mine.
