Gave customer price to clear stoppage and toilet and customer agreed. Pool toilet and used auger to push out toy car from toilet. Reset toilet and tested. Toilet is flushing as it should and no leaks are present at this time. Cleaned up work area. In basement, listen for noise and check valve is not really making a loud bang. Let customer know that if it gets louder we can replace quit check valve.
