|In response to Re: Sump pump drain line siphoning air|
: Thanks for your assistance! Where would I be able to purchase a "Watts Vacum vent"?
: A Watts vacuum vent would solve the problem. Your discharge pipe outlet must drop down lower than the pump for that to happen.
: : : : My sump pump discharge drain pipe rises up from the pit to the basement ceiling and runs along the ceiling for about 30 ft till it exits to the rear of the house. My problem is that once the pit has pumped clear and the pump shuts off, the evacuating water in the drainpipe is still traversing along the ceiling. While the water is draining from the pipe, there is negative pressure behind the evacuating water in the pipe and air is sucked up through the pump and through the check value. This causes a sucking and bubbling sound for 30 seconds after each pumping cycle. I have been looking for some sort of in-line air vent value to relieve the pressure. Does any one know of such a vent?
