Septic Tank Pump Help

Hey Everyone, I'm having a problem and looking for some help.....

I have an aerobic septic system and have been very pleased how it works...until now! Been here for 5 years and this is the first major problem that I've run into and haven't been able to fix.

My pump that sits in the gray water tank, the one that pumps the water to the sprinkler heads is spraying out of a small blow off hole on the side of the pump. When the water gets to where the float engages, it's blowing the water straight out the side of it instead of it going through the pipes and out the sprinklers. I can take a few pics if needed. I'm not familiar with the technical terms or anything, I can only tell you what I see from watching it.

Any ideas from anyone??? Your help is greatly appreciated.

There is a relief valve on the pump line?
If there is a hole on the side of the pump. It shouldn't be there.
I may be going way off base on this. If you could get a pic of the leak, that would be a big help.

If the pump looks like a 4" well pump. It could be the kind that has a wire guard going down the side of the pump.
On some there are two screws that hold the wire guard on. If they have fallen out. Water will spray out the holes.

There are so many installers out there with different ways of doing things.

Most of these types of pumps have a small hole in the discharge piping, right above the pump, to allow air to escape to keep the pump from becoming air locked. These holes are usually only about 1/8" in diameter. It's normal for a small amount of water to come out at this hole.
If the water is coming out of the pump housing itself, then you probably have a problem.
See if you can pinpoint where the spray is coming from.

It sounds as if the line from the pump to the sprinklers is plugged (or a valve is shut), which caused you to notice the flow from the little hole on the side of the pump or its discharge piping.

That's not a criticism, as few people would choose to spend their time watching a pump that is working correctly.
