The only thing I can think of is that the check valve, if there is one, is leaking back to the pit for about 10 seconds. The water flowing back could be making the noise. Does the water level in the pit change(get higher) as the noise happens? are there any ripples inthe water as the noiswe happens? kenz@zoeller.com
