What is the correct size of the pit that should have been used? 33" deep? also if I had him come back out to put the correct size in place what are the requirements as far as the bends in the vent pipe? I assume he would just put the correct pit liner with new cover in and vent the same way but I'm not sure if that's correct? please also give me the proper vent requirents for this application.

I have noticed that my sewage ejector cycles on very often for a short period of time. It does this when there is no water being used in the house, but seems to do more so when we have had rain. It does not appear to be the check valve as I do not hear any water running back into the pit. I am not confusing my sewage ejector with my sump pit. I know the difference between the two and know it is the sewage ejector. In the front yard, near the street, a stream of water flows from my yard into the street. It is a small amount of water, but is constant. It is pretty much at the lowest part of the yard. This is not the sump pit discharge, as that line is in the back of the yard. My thought is that ground water is seeping into the sewage ejector pit (don't understand how that could be) and that there is some type of obstruction or damage in the line leading out to the street. Any thoughts on this would be appreciated. Thanks

There used to be a sewage smell coming from the ejector pump. To solve this, I put a vacuum on reverse on the vent pipe and then sprayed a soapy solution onto the top of the pump. I watched some air bubbles come out of certain areas where the lid has either cracked or broken over the years. That seemed to solve the problem in the short term although if you leave it for a week or so, the smell would come back but usage on a day to day basis was fine. Now that the colder weather has appeared again with temps down to near zero overnight, the smell has come back on a daily basis in the morning, ie the water sits in the tank overnight and as soon as the pump goes in the morning, some air comes out of the leaks. I cannot find any more air seepage holes with the vacuum method but it seems odd that the symptom has come back with the colder weather. Could there be a negative pressure problem with the vent? Is there anyway to solve this? I have attached a picture of the pump: (a) lots of silicone as you can see my attempts to seal it. (b) the vent pipe runs about 6ft the right of the pump, then 10ft to the outside, then you'll see an outside picture, where it runs 25ft up to the roof. (c) The vent pipe looks like a 2inch pipe (6cm diameter) (d) There is no central stack venting in this house as all wastewater runs into the ejector pump in the basement and the only venting is this pipe from the ejector pump Pictures: https://drive.google.com/folder/d/0B...RjaXctX2c/edit Edit Did a diy smoke test today. Smoke comes out from where the basin joins the concrete. Presumably this could mean a crack above the water line in the tank. How would I know if sewage was leaking onto the concrete below? I cannot replace the basin as it is set into the concrete.

Thanks for the reply. The french drain is 10 inches deep from the concrete floor. i'm not sure if that is under the slab or above the slab. the french drain links to a sump pit and pumps water out when the bucket fills up. The pump is not constantly running. It runs more frequently in the spring after it rains but it comes on about once every hour in the summer months or less frequently. We've had no water issues since the french drain was installed and we had lots of water in the basement after heavy rainfalls before.
