Wells, Sump Pumps and Septic Sewage Systems - Septic System Sprinkler Pump

I have septic system which utilizes three spinkler's in the yard to disperse the treated water. The system is about four years old and the sprinklers no longer work and the treated water is flowing out the overflow line into the yard. Is this a job for a do-it-yourselfer? I assume there is a pump and a float valve that activates the pump when the tank fills. Failure in one of these processes is likely the problem. The system otherwise works fine and the overflow water appears clean with no odor. What type of pump will I likely find? (submersible or one mounted to the tank itself?)

Not my area of expertise, but don't you have to be licensed to work on these? Maybe someone will clear that up...

I have checked that out - where I live the system has to be inspected at the time of installation by the State, before water will be hooked up. In essence an engineer has to layout a system and contractor builds it. No rules regarding working on the existing system - only if you completely re-do the system. There is nothing wrong with the treatment center and the aerator pump is working fine. (hence no back up or odor) it is just the pump that pressurizes the sprinlers that has failed.

I would find out how many gallons per minute the sprinkler heads deliver. Then buy a submersible pump for effluent that will pump that many gallons per minute with 115 feet of total head. 115 feet of total head will give you around 50 psi. at the the sprinkler heads. And install the new pump like the old one. There is a float that will turn the pump on and off. Make sure that is working properly. You should have the greenest grass in town.

Before you go out and buy a new pump I would do some testing first.
You need to determine if there is power to the switch. Is the switch bad? Maybe someone pounded a stake in the ground and damaged the wire feeding the pump.
Is there a GFCI that is tripped? Why did it trip? Could be a bad pump.

Just FYI, I opened up the clean water tank to see what was going on. The pump is a submersed pump and you guessed it, the tank has about 70 gallons of water in it. Tested everything electrical going into the tank and it seems o.k. (getting power). Don't know about the pump yet. It seems like the whole set up prone to failure to me - with electrical lines going down to the bottom of the tank and all. The tank is going to have to be pumped out, so while they are at it they are going to pump the other two tanks and troubleshoot the pump. The good thing is I talked to the previous owners of the house and the pump was installed less than a year ago and is still under warranty, so the people who installed it previously is going to do the work. I let you know how it comes out.

I have a similar type system, I have had to replace both the pump out pump and the airator pump.
The pump out, pump is 110v submersable like a water well pump. The original lasted over 30 years.

Hope you got her fixed, it a pain when the water just flows out the top of the tank.

I had a waste water company come fix the problem. It was a poor installation to begin with and none of the electrical parts were waterproofed, thereby making the pump prematurely fail. It wasn't cheap, but it is working now.
